But real interest rates did not fall enough, because nominal interest rates cannot go below zero. By increasing inflation, the Fed would turn real interest rates seriously negative, thereby coercing thrifty households into spending instead of saving.

The zero lower bound arises because nominal interest rates cannot fall below zero. But if nominal interest rates stay positive, while inflation is negative, then real interest rates may become too high for an economy in recession, causing recession to become more severe and prolonged.

In a country with large fiscal deficits, the central bank may have to keep interest rates high to control inflation. In this scenario, budget cuts create room for interest rates to fall.

In normal times, any effort by a central bank to take short term interest rates too low for too long will boomerang. Short term market interest rates will fall, but, as investors begin to recognize the ultimate inflationary consequences of very loose monetary policy, longer term interest rates will rise.

In the US, households have a prepayment option on their mortgages should interest rates fall. Moreover, mortgages are usually securitized.

Summers s argument, in a nutshell, is that if the expected profitability of investment is falling, interest rates need to fall to the same extent. But interest rates cannot fall below zero (in fact, they may be stuck above zero if there is a strong desire to build up cash balances).

Interest Rates

Alternatively, low interest rates could push her (or her pension fund) to buy risky long maturity bonds. Given that these bonds are already aggressively priced, such a move might thus set her up for a fall when interest rates eventually rise.

In the very near term, certainly indeed, interest rates could still fall further. Over the longer term, however, this situation is definitely not stable.

In addition, a fall in the dollar could also push up inflation in the United States, leading to higher American and global interest rates.

When Interest Rates Rise

The Trouble With Interest Rates

Interest rates are still low.

If we push interest rates up, Greenspan thought, millions of Americans would become unemployed, to no one s benefit. If interest rates were allowed to fall, these extra workers would be employed building houses and making things to sell to all the people whose incomes come from the construction sector.

Slow Growth for US Interest Rates

Interest rates and inflation were high.

However, he believed that as the interest rate rise cycle of the Hong Kong Bank began and the Hong Kong dollar interest rates were normalizing, the situation that Hong Kong dollar interest rates were lower than US dollar interest rates would change in the future.

on the interest rates on private loans.

US Interest Rates Will Continue to Rise

The Long Mystery of Low Interest Rates

Real estate rental yields and stock market payouts are low, and real estate and stock prices may well fall as much as or more than bond prices if interest rates spike. Only businesses that can borrow long term now, lock in a low real interest rate, and invest in expanding their capacity can make the domestic bet that interest rates will rise.

China s Five Year Plan and Global Interest Rates

Do Low Interest Rates Ensure High Asset Prices?

Another interpretation is that awash with liquidity merely means that interest rates are low. But interest rates have been increasing around the world since 2003.

But, while the worldwide recession of 1981 2 brought inflation down rapidly, nominal long term interest rates did not fall immediately, for the world s markets were still not convinced. Hence, real long term rates remained quite high in the mid 1980 s.

Bank of England to keep interest rates at 0.25

Will Rising Interest Rates Torpedo Stock and House Prices?

Coverage rates still fall short of national objectives (80 per cent).

CAMBRIDGE Six months ago, I wrote that long term interest rates in the United States would rise, causing bond prices to fall by so much that an investor who owned ten year Treasury bonds would lose more from the decline in the value of the bond than he would gain from the difference between the bonds interest rate and the interest rates on short term money funds or bank deposits.

The total foreign debt of US residents (most of which is in US dollars) is above 7 trillion. This implies that any reduction in US interest rates would benefit the country as whole, relative to creditor countries, like Germany, where interest income would fall.

In this case, the price of loanable funds is the real interest rate. An expectation that interest rates will be high sometime in the next decade should mean high interest rates on long term bonds today.

On the contrary, rather than spiking higher following S P s unprecedented move, US market interest rates continued to fall, reaching record low levels. This seemingly contradictory fall in financing costs reflected an abundance of foreign capital seeking to invest in the US, including money fleeing from Europe.

The bottom line is that when interest rates rise, asset values will fall. It is during such periods particularly when asset values fall swiftly and substantially that we discover exactly how good our central bankers are at their main job reducing financial volatility and promoting economic stability.

Because the US Federal Reserve and other central banks have driven their short term interest rates close to zero, they cannot lower rates further in order to prevent deflation from raising the real rate of interest. Higher real interest rates discourage credit financed purchases by households and businesses.

Moreover, even if prices on average exhibit some downward flexibility, deflation necessarily increases the real rate of interest, given that nominal interest rates cannot fall below zero. The result is an increase in the cost of capital to firms, which lowers investment and exacerbates the crisis.

The low interest rate on long term Treasury bonds has also boosted demand for other long term assets that promise higher yields, including equities, farm land, high yield corporate bonds, gold, and real estate. When interest rates rise, the prices of those assets will fall as well.

When the markets see that coming, they will drive Italy s sovereign interest rates even lower. Given Italy s very large national debt, interest payments add more than 5 of GDP to the fiscal deficit. The combination of economic recovery and lower interest rates would produce a virtuous dynamic in which falling interest rates and a rising budget surplus are mutually reinforcing.

It is more difficult to deal with than inflation, in part for the technical reason that interest rates can be reduced only to zero. The closer to zero they fall, the more problematic monetary policy becomes.

In theory, as the economy picks up and interest rates begin to climb, central banks will simply pay higher interest rates on their reserves, so that they can finance their holdings of long term securities and shrink them slowly. But higher interest rates also imply large capital losses for central banks asset holdings.

The trend of Hong Kong dollar interest rates and US dollar interest rates will be more consistent. Everyone must be more careful to manage risks and prepared to cope with market fluctuations.

But the creation of the euro caused a sharp fall in interest rates in the peripheral countries, leading to debt financed housing bubbles and encouraging their governments to borrow to finance increased government spending. Amazingly, global financial markets ignored the credit risks of this sovereign debt, requiring only very small differences between interest rates on German bonds and those of Greece and other peripheral countries.

Third, contributing factors included low interest rates, compressed risk spreads, and global imbalances that accommodated low savings in the US, consumption in excess of output, and a mounting trade deficit. Absent the willingness of large developing countries to run trade surpluses and high savings rates relative to investment, the asset bubble in the US leading to a rise in domestic consumption and a fall in the savings rate would have triggered inflation and higher interest rates.

Moreover, ECB chief economist Otmar Issing predicts long term interest rates would go up not down as inflationary expectations increased. So cutting interest rates would not only be stupid it would be crazy.

Europe must ask itself how can interest rates induce a slowdown in 2007 when real interest rates have hardly budged despite an economically healthy 2006? Moreover, because profits are high in Europe, likely future increases in real interest rates needed to ensure price stability easily can be financed out of profits without economic disruption.
