European banks struggling - government lubrication needed!

European governments bail out more lenders - International Herald Tribune

As the US financial system holds its breath to see if the US government’s injection of $700 billion of liquidity actually results in new lending and restored business and consumer confidence, Europe is beginning to see its own government takeovers of European banks.

Regulators in Britain, Belgium and Iceland swooped in Monday to engineer emergency rescues of three banks with heavy exposure to soured mortgages, echoing moves underway in the United States.

In the latest sign of trouble to hit Europe from the global credit crisis, the Belgian, Dutch and Luxembourg governments announced a partial nationalization of the troubled Belgian-Dutch financial conglomerate Fortis, involving a combined injection of €11.2 billion from the three governments, which take a 49 percent stake…

Meanwhile, the British Treasury on Monday confirmed that it had seized the lender Bradford & Bingley - the third British bank to tumble this year - after no private buyers emerged.

Much as in the United States, several European banks have gotten into trouble as their assets tied to real estate have lost value due to the weak European and American real estate markets. As more and more borrowers are unable to pay their mortgages, banks’ assets decline in value and the banks’ willingness and ability to make new loans decreases. This limits the amount of credit available to households and firms, and with it their ability to make investments in consumer goods and capital. Tighter credit markets mean weaker aggregate demand (less consumption and investment), leading to slower or negative economic growth and rising unemployment.

In the past, when one bank got into trouble with bad assets like those tied to the real estate market, other private banks would come along and bail the troubled bank out, swapping cash for the assets, allowing the troubled bank to continue making loans. But when all banks find themselves in the midst of the same financial crisis, the likelihood of finding a private buyer for a struggling bank is low. This is where the government steps in:

The bailout of Fortis (Belgium’s largest commercial bank) orchestrated by the three neighboring countries (Belgium, Luxembourg and the Netherlands) and the ECB (European Central Bank)… was meant to restore confidence in the bank before the reopening of markets on Monday after a tumultuous week of imploding share values at Fortis. The shares gained 4.8 percent to €5.45 Monday.

In Britain, regulators were unable to find buyers to keep Bradford & Bingley afloat. The lender’s shares are down 90 percent from the peak, touching new depths Friday as an already skittish market punished the company, prompting the talks.

When the private sector is unable or unwilling to purchase the assets of a bank that has experienced a write down of its asset value, the government must intervene to make sure such banks have the liquidity (meaning the hard cash) they need to make loans to borrowers, whose spending is needed to keep the economy going.

In the US, the government has agreed to trade $700 billion in hard, loanable and spendable cash, in exchange for financial assets tied to bad mortgages worth something less than $700 billion. If the swap has the effect the government hopes it will, then lending institutions will feel more confidence and be willing to loan cash to each other and to borrowers (households and firms), spending in the economy will increase (consumption and investment) and aggregate demand will rise, meaning more total output, more employment and higher incomes. In addition, more lending will also lead to an increase in the capital stock, effectively pushing the American and European aggregate supply curves outwards, leading to a more stable rate of inflation (a major worry for both economies as oil prices hit record levels this year).

In spite of the recent round of bailouts in both the US and Europe, confidence among European firms and households is low:

Euro-zone economic confidence plunged to its lowest level in seven years in September, the EU said Monday.

A regular survey of European companies and consumers showed the index of confidence in the economy falling to 87.7, close to a 2001 trough, the European Commission said.

The EU executive warned that the survey carried out in the first two weeks of September may not fully reflect growing gloom in the last few weeks as worries over a U.S. and European recession widened on a financial market crisis.

Industry, services and construction were all more pessimistic than a month ago, it said, while consumer confidence was unchanged from a low level. Retailers were slightly more upbeat about their prospects.

It said industry managers’ employment expectations fell - meaning they believe they may have to cut jobs - although services companies were more hopeful.

Consumers thought that unemployment would increase in future months and expect prices to rise.

The 15 nations that share the euro are battling high inflation as oil prices remain high - although below recent record levels - and increasing fears that a financial crisis will freeze or sharply hike the cost of borrowing.

That would slow growth as companies found it harder to get credit and people faced high costs to buy homes. The U.S. government is trying to stave off tighter credit conditions by buying up hundreds of billions of dollars of bad debt from major lenders

As can be seen, falling confidence and tighter credit markets are evil twins. If the Euro zone economy is to avoid recession, the European Central Bank and the governments of the 15 Euro nations should follow closely events in the US over the next few weeks. The $700 billion injection of liquidity, if successful, will act as lubrication in the engine of the US economy.

Think of it this way: lately, the US economic engine has slowed down. Friction in the financial markets has slowed the flow of cash from households to banks to firms and back to households. In IB and AP Economics terms, the circular flow of money and income has slowed to a halt. To get the engine moving again, cash is needed. Banks with liquid cash are more willing to lend to one another and to households and firms. A healthy economy depends on a well lubricated economic engine, which in today’s world means a functioning financial market.

The government bailouts in the US and Europe are intended to do one thing: lubricate that engine and get the economy moving forward once more.

Discussion question:

  1. Why does the government need to intervene in financial markets? Shouldn’t those who took risks by making bad loans pay for their mistakes and be allowed to go under?
  2. What will it take to turn consumer and investor confidence around in Europe?
  3. How might the crisis in the financial markets affect you and me in the real world?

It may not be a recession, but it sure feels like one…

FT.com / Columnists / Wolfgang Munchau - Inflation and the lessons of the 1970s

It seem that everyone’s speculating about the US economy today. Recession or no recession, that is the question. The economy has even surpassed the Iraq War as the number one issue in the US presidential race! John McCain, who has publicly admitted that economics is not his strong suit, may just find himself in trouble in a general election where the most important concern among voters is the economic situation.

So what IS that situation, anyway? Is the US in a recession? In other words, has real gross domestic, or total output in the US economy, actually declined over the last six months? Technically, the answer is no. My fellow blogger, Steve Latter, explains this clearly here. What is true, on the other hand, is that the current situation shares many similarities to the global economic slowdown that did occur in the 1970s.

In 1973 OPEC, the newly formed oil cartel consisting at the time of only Arab states, reduced its output of oil and cut off exports to the United States in response to US support of Israel in the Yom Kippur War, in which the Israelis officially occupied the Palestinian territories of the West Bank and Gaza and seized the Golan Heights from the sovereign nation of Syria. To punish the US for its position on this conflict, OPEC cut off supplies of oil to the west, driving gas and energy prices upwards by 70%, triggering a supply shock characterized by a decline in total output and an increase in both unemployment and inflation, a phenomenon known as stagflation: a macroeconomic policy maker’s worst nightmare.

Recently the world has seen a similar (albeit of a different cause) rise in the price of oil and energy prices. Today the rise in energy prices is driven primarily by rising demand, rather than reduced supply (since the 1970s the OPEC cartel has grown to include many non-Arab nations, making it harder to achieve collusion to restrict output and drive up oil prices). Global demand for oil has risen steadily, driven ever higher due to rapid growth in China and other developing nations, and exacerbated by the falling value of the dollar, the currency in which oil prices are denominated.

The supply shocks of today have combined with falling aggregate demand in the US due to weak consumer spending to slow real growth rates to nearlry 0%. So technically, the US has avoided a recession, but the effect on American workers and consumers may be just as painful as the real recession of the 1970s. In order to prevent the “r” word from becoming a reality today, central banks (including the US Fed) have eased money supplies, lowering interest rates, fueling even greater increases in the price level.

…the global weighted average inflation rate will be 5.4 per cent this year, while the global money market interest rate is currently only 4.3 per cent. This means that global short-term real interest rates are negative – at a time when inflation is rapidly accelerating. As monetary policy has been excessively accommodating for more than a decade, inflationary pressures have built up in the global economy.

Central bankers like Ben Bernanke have to make tough decisions sometimes, weighing the trade-off between unemployment and inflation, and determining their monetary policies based on whatever they deem to be the “lesser of two evils”. Rising energy prices have forced firms to cut either cut back their production and raise the price of their products, both actions that result in less overall spending and output in the economy. Falling house prices have led consumers to cut back their own spending, further reducing demand for firms’ output. These factors have all pushed the unemployment rate from around 4.8% a year ago to 5.1% today, which combined with an estimated additional 3-5% of American workers having dropped out of the workforce, (referred to by the Department of Labor as “discouraged workers”) paints a pretty ugly picture of the reality for the American worker today.

The harsh reality of the weak labor market has led Mr. Bernanke and the Fed to pursue an expansionary monetary policy aimed at avoiding further increases in the unemployment rate and decreases in the GDP growth rate. Expansionary monetary policy means lower interest rates, with the goal being increased consumption and investment, both factors that could worsen the inflation problem already experienced thanks to the global supply shock. Evidence indicates that the inflation problem, even in the US where slow growth usually leads to lower price levels, is not going away:

In the US, a survey-based measure of inflationary expectations recently showed an increase to more than 5 per cent. I would estimate there are now several hundred basis points of difference between the current Fed funds rate and an interest rate that would be consistent with price stability in the medium term.

…meaning the Fed, in its attempt to avoid recession and rising unemployment, has created a condition where real interest rates are actually negative, a highly inflationary condition. All this wouldn’t be so bad if wages in the US were rising along with the price level. This however, does not appear to be happening:

The main difference between the situation in the 1970s and now is today’s absence of wage inflation, which explains why absolute inflation rates are a little more moderate. I guess this is probably because of some combination of deregulated labour markets and globalisation. But the lack of wage-push inflation is not necessarily good news. Falling real wages mean falling disposable income and tighter credit conditions mean less borrowing for consumption.

Rising prices for energy, transportation and food have put American households in a tough situation. In the past, periods of inflation have often been characterized by rising wages, meaning the full brunt of nominal price level increases was not entirely born by the American worker. Today, on the other hand, a recession has thus far been avoided, but the combination of record numbers of “discouraged workers”, rising unemployment and inflation may make the pain of our current economic situation just as real as recessions of the past.

In the words of billionaire investor and economic sage Warren Buffett just today:

“I believe that we are already in a recession… Perhaps not in the sense as defined by economists. … But people are already feeling the effects of a recession.”

“It will be deeper and longer than what many think,” he added.

Discussion Questions:

  1. What is the difference between nominal and real GDP? Which must decline in order for the economy to be in a recession?
  2. What impact do rising energy prices have on the behavior of individual firms?
  3. Why are low interest rates likely to make the inflation problem even worse?

China’s “silver bullet” - a strong RMB could solve her biggest economic woes…

Asia Sentinel - The Answer for China’s Inflation
Two goals recently voiced by the Chinese leadership: increased consumer spending and reduced inflation. These are worthy goals for policymakers to pursue; if accomplished, they will mean increased well-being for the average Demand-pull inflation caused by increase in consumptionChinese household, which will enjoy more goods and services at lower prices.

The problem is, increased consumption usually means rising prices, as can be clearly illustrated in an aggregate demand / aggregate supply diagram. Household spending makes up somewhere around 40% of China’s GDP, exports, government spending and investment account for the rest. Whenever one component of total expenditures increase in the economy, all other things equal, the price level will rise.

Only two things could happen to make the Chinese leadership’s goal of increased consumer spending and stable prices a reality: either productivity in the economy must increase more rapidly than consumer spending, shifting aggregate supply outward, or another component of aggregate demand must be reduced more rapidly than consumption increases, offsetting the increase in overall expenditures cause by rising consumption.

So what magical combination of fiscal and monetary policy can be employed to both increase consumption and stabilize the price level? The answer may not rest purely in the realm of domestic macroeconomic policy-making, but rather in the foreign exchange markets, where a weak RMB has kept domestic consumption low and net exports (thus the price level) high. Allowing the RMB to appreciate should make “magic” happen and lead to rising domestic consumption and disinflation simultaneously:

A stronger currency, commensurate with China’s increased economic strength, would both tamp down inflation and allow Chinese consumers to buy more goods and services. However, for reasons not entirely clear to me, or few others for that matter, China’s leaders are resisting this simple and beneficial solution.

The Chinese leadership’s stated goal in prodding their citizens to spend more is to decrease their economy’s dependence on exports. If the Chinese, who currently save 50 percent of their incomes, saved less, more of their production would be consumed locally. As a result, China would be less vulnerable to economic downturns abroad. Without a vibrant domestic market, over-leveraged Americans will apparently remain China’s most important customers.

A strengthened yuan would lower the real costs of goods for domestic consumers and allow the Chinese themselves to compete more evenly with consumers in other nations to whom they currently send the fruits of their labor. As goods become more affordable in China, the Chinese would naturally consume more. A rising yuan would therefore kill two birds with one stone: it would reverse recent consumer price increases and it would induce Chinese consumers to buy their own products.

Some members of the US Congress estimated sometime last year that the Chinese currency was undervalued by 27%, leading certain politicians to call for an across the board tariff on all Chinese imports to the United States. Such protectionist sentiment was not uncommon 12 months ago, but as America faces its own economic slowdown, compounded by rising inflation and the falling value of the dollar, such calls for more taxes on imports have disappeared from Washington.

The sensible action for the Chinese to take in response to its own overheating economy (letting the RMB appreciate in order to relieve inflation and encourage domestic consumption) could spell economic doom for the US. As China adopts a “strong yuan” policy, its demand for US dollar-denominated financial assets, including government debt, will decline, reducing demand in the US bond market, lowering bond prices and driving up interest rates in the US. Higher US rates will discourage investment and consumption, exacerbating the slowdown already underway in America. Furthermore, reduced demand for US assets by China will cause demand for the dollar to slide in foreign exchange markets. Since much of American’s household spending is on imports, inflation will rise in America as not only Chinese goods, but all imports, are now more expensive to Americans.

Usually in economics class, we adopt the frame of mind that economics is not a zero-sum game. In other words, through free trade based on comparative advantage and specialization, individuals and nations will benefit due to increased total output, increased productivity, higher incomes, and greater variety of goods and services produced within and among communities and nations. In the case of China and the US today, on the other hand, we appear to be in a situation where increased consumption by Chinese may be achievable only at the expense of American consumers, who because of rising interest rates and a falling dollar, may be forced to live “within their means” for the first time in decades.

Discussion questions:

  1. Why is a strong RMB necessary to simultaneously increase consumption and reduce inflation in China?
  2. Why would interest rates in the US rise if China adopted a “strong RMB” policy?
  3. Would Americans be better off without trade with China? What about the statement that Americans will be worse off if China is to achieve greater levels of domestic consumption?

Exactly what does inflation measure?

All of Inflation’s Little Parts - The New York Times

This is really cool… The Bureau of Labor Statistics releases monthly data on prices to let Americans know just how much inflation affects their livelihoods. The Consumer Price Index, which is studied in both AP and IB Economics, consists of a “basket of goods”, that when bundled together represent the “typical” American consumer’s expenditures. The CPI is broken into a few broad categories:

  • Health care
  • Apparel
  • Housing
  • Education/communication
  • Recreation
  • Food/beverages
  • Transportation
  • Miscellaneous

Here’s the cool part, though… within each broad category the BLS tracks the prices of dozens of specific categories, around 200 to be precise. Each of these is then broken down into individual products, around 84,000 in total! The task of tracking the prices of 84,000 individual goods and services every month is daunting, and just thinking about the tedium of this job makes me glad I’m a teacher!

The New York Times has assembled what can only be described as a mosaic of consumption, organizing the 200 specific CPI categories into what looks like an ornate stained-glass window, in which the size of each piece of glass represents the percentage of Americans’ income that go towards each specific category. Some of the categories represented in this mosaic include items such as:

  • Oils and peanut butter (0.1%)
  • Gasoline (5.2%)
  • Garbage collection (0.3%)
  • Internet (0.3%)
  • Nursing homes (0.1%)
  • New cars and trucks (4.6%)
  • DVDs (0.2%)

This graphic is a great tool for teaching and understanding the Consumer Price Index, not to mention a beautiful pattern for any stained-glass artist looking for inspiration!

Excuse me, China… could you lend us another billion?

The $1.4 Trillion Question - James Fallows - the Atlantic

What’s the deal with American consumers? How, exactly, does a nation’s average savings rate fall to 2%, then 1%, and then become negative, like in the US over the last couple of years? What does negative savings actually mean? It means that Americans consumer more than they actually produce.

On the micro level, the only way to consume beyond ones income is to borrow from someone else to pay for the additional consumption. In other words, savings must be negative for one to consume beyond his or her income. The US is a nation of borrowers, but from whom do we borrow? China, in short.

China is a nation of “savers”, where national savings averages 50% of income. What exactly does this mean? Well, just the opposite what negative savings means; rather than consuming more than it produces, the Chinese consume only about half of what it produces. Here’s how James Fallows, a Shanghai-based journalist, explains the China/US dilemma:

Any economist will say that Americans have been living better than they should—which is by definition the case when a nation’s total consumption is greater than its total production, as America’s now is. Economists will also point out that, despite the glitter of China’s big cities and the rise of its billionaire class, China’s people have been living far worse than they could. That’s what it means when a nation consumes only half of what it produces, as China does.

What happens to the rest of China’s output? Naturally, it’s shipped overseas for Americans and others in the West to consume. The irony is that the consumption of China’s products has been kept affordable and cheap thanks to the actions the Chinese government has taken to suppress the value of the RMB, thus keeping its products cheap and attractive to American consumers.

When the dollar is strong, the following (good) things happen: the price of food, fuel, imports, manufactured goods, and just about everything else (vacations in Europe!) goes down. The value of the stock market, real estate, and just about all other American assets goes up. Interest rates go down—for mortgage loans, credit-card debt, and commercial borrowing. Tax rates can be lower, since foreign lenders hold down the cost of financing the national debt. The only problem is that American-made goods become more expensive for foreigners, so the country’s exports are hurt.

When the dollar is weak, the following (bad) things happen: the price of food, fuel, imports, and so on (no more vacations in Europe) goes up. The value of the stock market, real estate, and just about all other American assets goes down. Interest rates are higher. Tax rates can be higher, to cover the increased cost of financing the national debt. The only benefit is that American-made goods become cheaper for foreigners, which helps create new jobs and can raise the value of export-oriented American firms (winemakers in California, producers of medical devices in New England).

Clearly, a strong dollar is good for America in many ways. The dollar’s strength in the last decade can be credited partially to the Chinese, who have been buying dollar denominated assets in record numbers over the last seven years.

By 1996, China amassed its first $100 billion in foreign assets, mainly held in U.S. dollars. (China considers these holdings a state secret, so all numbers come from analyses by outside experts.) By 2001, that sum doubled to about $200 billion… Since then, it has increased more than sixfold, by well over a trillion dollars, and China’s foreign reserves are now the largest in the world.

China’s purchase of American assets keeps demand for dollars on foreign exchange markets strong, thus the value of the dollar high relative to other currencies, allowing American firms and consumers the benefits of a strong dollars described above.

As we learn in AP Economics, a nation’s balance of payments consists of the current account, which measures the difference between a country’s expenditures on imports and its income from exports (China last year had a $232 billion current account surplus with the US, meaning the US bought more Chinese goods than China bought of American goods), and the capital account, which measures the difference between the inflows of foreign money for the purchase of real and financial assets at home and the outflows of currency for the purchase of foreign assets abroad. In the capital account, China maintains a deficit (meaning China holds more American financial and real assets than America does of China’s), to off-set its current account surplus.

The two accounts together, by definition, balance out… usually. Any deficit in the China’s capital account that does not cover the surplus in its current account can be held as foreign exchange reserves by the People’s Bank of China. The PBOC, however, prefers not to hold excess dollars in reserve, as the dollar’s value is continually eroded by inflation and depreciation; therefore it invests the hundreds of billions of excess dollars it receives from Americans’ purchase of Chinese goods back into the American economy, buying up American assets, with the aim of earning interest on these assets that exceed the depreciation and inflation rates.

The “assets” the Chinese are using their large influx of dollars to buy are primarily US government bonds. The government issues these bonds to finance its budget deficits (when government spending is greater than tax revenue; this figure was projected at around $400 billion this year alone!), and the Chinese are happy to buy these bonds for a couple of reasons: They are secure investments, meaning that unless the US government collapses, the interest on US bonds is guaranteed income for China. That’s one reason; but the primary reason is that the purchase of these bonds puts US dollars that were originally spent by American consumers on Chinese imports right back into the hands of American consumers (via government spending or tax rebates), so they can continue buying more Chinese imports.

The Chinese demand for dollar denominated financial assets, including government bonds, corporate stocks and bonds, and real assets like real estate, factories, buildings and so on, has resulted in a long period of a strong dollar. If the Chinese ever decided to stem the flow of dollars into American assets, the dollar’s value would plummet to record lows, leading to high inflation and eventually a balancing of America’s enormous current account deficit with China and the rest of the world.

However, a falling dollar is the last thing China wants to see happen, for two reasons: One, it would make Chinese imports more expensive thus less attractive to American households, thus harming Chinese manufacturers and slowing growth in China. Two, US dollars are an asset to China. Its $1.4 billion of US debt would evaporate if the dollar took a major plunge. To China, this would represent a loss of national wealth; in effect all that “savings” that makes China so unique would disappear as the dollar dived relative to the RMB. For these reasons, it seems likely that China will continue to be a willing buyer of America’s debt, thus the financier of Americans’ insanely high consumptive lifestyle.

When it comes to America’s low personal savings rates, I have a theory here as to why we can’t break the consumptive habit that’s caused us to run up $9.3 trillion of national debt. It relates to something I teach my Asian History students when we study ancient China.

Confucius said something about government that might just explain why Americans have evolved into the negative savers that we are: “If a government desires what is good, the people will be good. The character of a ruler is like wind and that of the people like grass. In whatever direction the wind blows, the grass always bends.”

From the Help Desk: Long-run vs. short-run economic growth, consupmtion and investment…

*Click on the graphs to see full-size versions

The following message was submitted through the AP/IB Econ Help Desk:

Jason,

An AP Macro Question: Comes from the recently published AP Practice Exam

An increase in which of the following is most likely to promote economic growth?

A. Consumption Spending
B. Investment Tax Credits
C The natural rate of unemployment
D The trade deficit
E Real Interest Rates.

The answer is B, and I understand the economic principles of why that would promote economic growth, but what I can’t answer for my students is why A, Consumption Spending wouldn’t work. I know that consumption spending makes up part of the demand in aggregate demand, but I can’t help but think that an increase in it, would promote economic growth.

Thanks, “Econ Teacher”

For what it’s worth, here is my reply:

Hello “Econ Teacher”,

That’s a good question. I would explain to my students that in the short-run, an increase in AD alone will lead to some growth, but would be accompanied by inflation, since AS does not shift out when consumption increases. However, an investment tax credit will result in REAL long-run economic growth (by real I mean nominal GDP will increase while the price level remains stable), since it encourages investment. Investment is a determinant of AD, just like consumption, so AD will shift out, but it is also a determinant of AS, since firms are investing in capital. Increase the quantity or the quality of capital, and labor becomes more productive. Greater productivity shifts out AS, leading to growth AND stable prices.

Economic growth is defined, in terms of the AD/AS model, as an outward shift of both AD and AS. Increases in consumption will increase AD, but this will lead to inflation, and in the long run, workers will demand higher wages, increasing the costs of production and shifting AS leftward, returning the economy to the full employment level of output at an even higher price level, i.e. no economic growth occurs (see graph to the right). Investment, however, encouraged through a tax credit, will have positive demand and supply side effects, resulting in real economic growth and stable prices (see graph below)

Hope that helps!

Helicopter Ben and Monetary Policy: the cartoon version!

Monetary Policy

Much hoopla is made over the US Federal Reserve’s power to affect markets through its injections of liquidity into the economy. These days, the Fed appears to have some new tricks up its sleeve, but still uses its traditionally dominant tool of Open Market Operations to affect the Federal Funds rate, and thus the interest rates that commercial banks charge borrowers financing consumption and investment.

The power of monetary policy lies in the fact that spending stimulus can be achieved without running the risk of crowding-out, wherein expansionary fiscal policy drives up interest rates, potentially off-setting any increases in aggregate demand by triggering declines in consumption and investment due to increased borrowing costs.The whole aim of expansionary monetary policy, on the other hand, is to drive interest down by increasing the reserves held by commercial banks.

The cartoon above illustrates the process that leads to lower interest rates and greater spending when the Fed undertakes expansionary open market operations. Government bonds (the blue bills above) are held as assets by both commercial banks and the public. These are illiquid, meaning they cannot be spent. In order to stimulate new spending, the Fed can take some of its reserves of money (the green bills), and buy bonds from the public and banks.

Banks receive cash from the Fed, which increases their excess reserves. Further, the public will deposit the checks they receive from the Fed into their banks, increasing checkable deposits, which add to both the banks’ required reserves and excess reserves. The result is banks now have new liquidity that they want desperately to lend out in order to earn interest (remember, banks rarely want to hold onto their excess reserves, because inflation will erode the value of any money that’s not earning interest!).

When banks’ reserves increase, due to their growing checkable deposits and the inflow of cash from the Fed’s purchase of bonds, the supply of “federal funds” shifts down, lowering the interest rates that banks charge one another for overnight loans. These are loans that banks often give and receive in order to meet their reserve requirements at the end of a business day.

For example: If Bank A has finds at the end of the day that it has received more deposits than withdrawals, and it now has $1m more in its reserves than it is required to have, it wants to lend that money out as soon as possible to earn interest on it. Bank B, it just so happens, received more withdrawals than it did deposits during the day, and is $1m short of its required reserves at day’s end. Bank B can borrow Bank A’s excess reserves in order to meet its reserve requirement. Bank A will not lend it for free, however, and the rate it charges is called the “federal funds” rate, since banks’ reserves are held predominantly by their district’s Federal Reserve Bank.Federal Funds market

When the Fed buys bonds, all banks experience an increase in their reserves, meaning the supply of federal funds shifts out (or down in the graph above), lowering the “price” of federal funds, i.e. the federal funds rate. Lower interest rates on overnight loans will encourage banks to be more generous in their lending activity, allowing them to lower the prime interest rate (the rate they charge their most credit-worthy borrowers), which in turn should have a downward effect on all other interest rates.

Expansionary monetary policy involves the buying of government bonds on from the public and commercial banks by the Federal Reserve Bank. The result of this buying of bonds is an increase in the money supply, a decrease in real interest rates, and hopefully the stimulus of aggregate demand through new consumption and investment. Unlike expansionary fiscal policy (such as the stimulus package announced by Congress last month), crowding-out should not occur. Ideally, lowering the federal funds rate will lead to lower interest rates across the economy as a whole.

This, however, does not always transpire. In a future post, we’ll discuss why, and look at what the Fed is experimenting with today to stimulate investment and consumption, in response to the apparent failure of open market operations at providing the needed stimulus.
