A spike in long term rates would lower the price of JGBs, destroying household wealth and, in turn, reducing consumer spending.

This is intended to stimulate private spending by bringing down the rate of interest at which banks lend to their customers.

China s Interest Rate Challenge

The Real Interest Rate Risk

Officially, America still talks about the virtues of a strong dollar, but lowering interest rates weakens the exchange rate.

America s Interest Rate Puzzle

Lower interest rates are not a solution to this dilemma.

The European Central Bank has lowered its main refinancing rate eight times, by a total of 325 basis points, to 0.75 . The Bank of Japan has twice lowered its interest rate, which now stands at 0.1 .

The central bank has already cut its benchmark interest rate by 150 basis points, to 11 , and the downward trend is expected to take real rates to record lows in the post crisis period.

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 .

A spike in long term rates would lower the price of JGBs, destroying household wealth and, in turn, reducing consumer spending. The higher interest rates would also apply to corporate bonds and bank loans, weakening business investment.

In other circumstances, the US would benefit from the exchange rate weakening that follows from lower interest rates a kind of beggar thy neighbor competitive devaluation that would come at the expense of America s trading partners.

Lower the interest rate too much, and inflation and monetary instability result. Raise it too much, and the economy slides into recession and unemployment.

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.

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).

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.

Similarly, new processes may make it cheaper to make the same product.

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

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

These policies did succeed in lowering long term interest rates.

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.

When the central bank succeeded, it lowered those rates and the economy bounced back.

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.

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.

After all, if a country s debt GDP ratio is to decline without austerity, the interest rate that it pays on its debt must be lower than its GDP growth rate.

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.

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.

The process of reducing interest rates anchored on a solid tax policy and enabled by the removal of institutional obstacles (such as the rule of remuneration of savings accounts) was extended to the second half of 2012, leading to a real annual rate under 2 .

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.

So, while bringing down short term T bill rates to near zero has failed, the hope is that bringing down longer term interest rates will spur the economy.

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 .

He has cut short term interest rates to the bone.

Interest rate cuts after bubbles burst would be a safer way to safeguard the economy.

Government can either spend more money itself, or try to stimulate private spending by cutting taxes or lowering interest rates.

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.

Although it is difficult to anticipate how high long term interest rates will eventually rise, the large budget deficit and the rising level of the national debt suggest that the real rate will be higher than 2 . A higher rate of expected inflation would also cause the total nominal rate to be greater than 5 .

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