Under these conditions, the Fed will want to raise the interest rate to prevent an acceleration of inflation.

Some are recalcitrant and are more than willing to see the euro rise because, with rate hikes off the table, the strong euro may be the only way left for fighting the incipient inflation they fear.

China s Interest Rate Challenge

The Real Interest Rate Risk

But such an insignificant rate hike will do little to relieve long term pressures, because investors will expect more rate hikes and move money into China, increasing upward pressure on the yuan s exchange rate.

Experts estimate that, in terms of guarding against inflation, the euro s appreciation has been equivalent to about 35 basis points rise in the interest rate.

Finally and perhaps most importantly the People s Bank of China has raised its benchmark policy rate five times since October 2010.

America s Interest Rate Puzzle

Lower interest rates are not a solution to this dilemma.

And it is the real interest rate not the money rate that counts for economic growth.

At present, the interest rate is less than 0.5 .

The oil price goes through the floor. That company goes out of business, and then you can bring the oil price back up.

(The Fed raised its benchmark federal funds rate from 1 in 2004 to 5.25 in 2006 and held it there until August 2007).

Emerging Markets After the Fed Hikes Rates

Because the inflation rate is also about 2 , this implies a negative real interest rate, which is confirmed by the interest rate of 0.6 on ten year Treasury Inflation Protected Securities (TIPS), which adjust interest and principal payments for inflation.

But the current version of this promise not to raise the overnight interest rate until the unemployment rate drops below 6.5 no longer implies that short term rates will remain low for an extended period.

The second element of the debt relief package would be more innovative If Greece s economy performs well, the generous extension of maturities can be clawed back or the interest rate raised.

However, this is no longer applied since the central bank started changing rates by 0.25 percentage points on October 19, 2010 (which was a rate increase).

Right before the Fed acted, the Reserve Bank of India raised its benchmark short term interest rate by 25 basis points, to 6.25 , to fight inflation, and China s central bank now indicates that it might raise interest rates further.

But when prices are falling, the real interest rate exceeds the nominal rate.

In Japan, the ten year rate has drifted to below 0.8 .

And, due to rising consumer prices, the nominal interest rate will continue to rise.

Why the Fed Should Postpone Rate Hikes

There could also be strong pressure from the US Congress not to raise interest rates.

In May 2006, the fairly free domestic interbank rate was just 1.62 , while the US Federal Funds rate was 5 .

An independent monetary policy requires a flexible exchange rate, not a revaluation.

According to the followers of Knut Wicksell, the central bank must keep the market rate of interest near the natural rate of interest.

But the interest rate that Greece must pay buyers of its government bonds has shot up to a record high level of nearly 9 5.9 percentage points above the benchmark rate paid by Germany.

The second adverse effect of deflation is to raise the real interest rate, that is, the difference between the nominal interest rate and the rate of inflation.

Since the interest rate set by the ECB is now less than 1 , there is little difference between its current monetary policy and what the Bank of Spain would do if it could set its own interest rate. But when the euro zone starts to recover, the ECB might choose to raise the interest rate before a higher rate would be appropriate for Spain, which could exacerbate Spanish unemployment.

Although it has not indicated just when rates will rise or how high they will go, the Congressional Budget Office (CBO) projects that the rate on ten year Treasuries will rise above 5 by 2019 and remain above that level for the next five years.

As a result, the interest rate for 12 month fixed deposits has reached 3.9 .

All the above assumes that the interest rate remains constant throughout the whole period.

Domestic deflation means that the real interest rate on Japanese bonds is higher than the nominal rate.

Foreign investors then sent their money to New York to take advantage of the higher rates.

In these circumstances, there is no good reason to wait to raise interest rates.

The first, the Secular Stagnation Hypothesis, has been proposed by Larry Summers. Its key premise is that the equilibrium interest rate at which demand would balance supply is currently below the actual interest rate.

Recently, the PBC raised the one year lending rate and the one year deposit to 6.56 and 3.5 , respectively.

A direct effect of the higher interest rate would be to increase the budget deficit and the rate of growth of government debt.

Past experience implies that the real rate will rise to at least 2 , taking the total nominal interest rate to more than 4 , even if expected inflation remains at just 2 .

And that is important, because a rise in the federal funds rate will cause other, somewhat longer interest rates to increase as well.

Monetary policy is now drawing on a more comprehensive toolkit, such as the policy rate, the interest rate corridor, required reserve ratios, and the reserve option mechanism.

Politicians will not sit quietly, however, if the Fed attempts to raise rates.

Indeed, inflation may even force the Bank to raise interest rates by the fall.

The Chinese government is hastening its shopping spree in America these days, pushing up the renminbi s exchange rate slowly but steadily.
