Readers Question: Hello can you please tell me what the disadvantages of using interest rates would be for the economy?
Interest rates are used to try and achieve low inflation and stable, sustainable economic growth. However, interest rates are limited, they can’t always achieve all the governments’ macro economic objectives at once.
Interest Rates and Inflation
For example, if an economy is overheating (with inflation increasing), a rise in interest rates can help to reduce growth of aggregate demand and reduce inflationary pressure. If implemented correctly, this can avoid a boom and bust economic cycle. For example, in the late 1980s, interest rates were increased in response to higher inflation.
In a recession, interest rates can be cut. This reduces cost of borrowing and helps firms and householders avoid being overwhelmed with debt repayments. Low interest rates can help the economy to recover and achieve positive growth.
When Are Interest Rates Damaging for an Economy?
Conflicting With different macroeconomic Objectives.
High interest rates in 1991 and 1992 led to recession of 1991 and early 1992.
In 1990, the UK had high inflation and was a member of the ERM – a semi fixed exchange rate. The pound was falling to the lower limit of the exchange rate band. Therefore, between 1990 and 1992, the government increased interest rates to 12% (and for a few hours to 15%). This did help reduce inflation, and for a short period enabled UK to remain in ERM.
However, arguably, interest rates were far too high for the economic situation. The government persisted with high interest rates, even when the economy was in recession and unemployment rising. The government were pursuing a strong exchange rate, when this shouldn’t have been their primary macroeconomic objective. see: Recession of 1991-92
High interest rates created several problems
- Demand in economy fell creating unemployment
- Home-owners were faced with very high mortgage interest payments. This led to a record rise in home repossessions.
- It caused a bust in the housing market, which caused house prices to fall for four years.
Problems of Relying on Interest Rates
- Relying on interest rates to reduce inflation, disproportionately hits debtors and homeowners.
- Cutting interest rates to boost growth, disproportionately hits savers (currently many savers have negative interest rates)
- The impact of interest rates can be limited. For example, we are currently in a liquidity trap, which means zero interest rates are being ineffective in boosting growth.
This doesn’t mean interest rates are always bad. With hindsight, the government should have raised interest rates earlier to prevent inflation and reduce the size of the boom. When the economy went into recession, they should have been quicker to reduce them.
In a liquidity trap, lower interest rates can fail to promote economic growth. In March 2009, the UK, cut interest rates to 0.5%, but this failed to prevent the deepest recession since the 1930s. Therefore, lower interest rates may be insufficient to boost demand. In this case it may be necessary to pursue unconventional monetary policies such as quantitative easing.
