The lower the interest rate, the more willing people are to borrow money to make big purchases, such as houses or cars. When consumers pay less in interest, this gives them more money to spend, which can create a ripple effect of increased spending throughout the economy.

Higher interest rates are thought to affect consumer spending through both substitution and income effects. Higher interest rates lower consumption through the substitution effect, because current consumption becomes expensive relative to saving–households reduce their spending today in favor of spending tomorrow.

Under a system of fractional reserve banking, interest rates and inflation tend to be inversely correlated. As interest rates are increased, consumers tend to save because returns from savings are higher. With less disposable income being spent, the economy slows and inflation decreases.

The rate at which financial institutions can lend to one another directly impacts consumption at the household level. The Federal Reserve can better control for consumption levels by identifying the optimal interest rate. This study suggests that lower interest rates lead to higher consumption levels.

However, higher interest income raises the permanent income of net lenders and, thus, tend to increase their consumption and decrease savings through the income effect. Higher inflation depresses the value of real wealth and through the wealth effect negatively affects consumption and thus enhances savings.

Interest Rate Changes Interest rates affect the cost of borrowing money over time, and so lower interest rates make borrowing cheaper – allowing people to spend and invest more freely. Increasing rates, on the other hand makes borrowing more costly and can reign in spending in favor of saving.

Interest rates determine the amount of interest payments that savers will receive on their deposits. An increase in interest rates will make saving more attractive and should encourage saving. A cut in interest rates will reduce the rewards of saving and will tend to discourage saving.

The higher real interest rate reduces consumption, but future income is higher, which increases consumption. If investment actually rises, then the increase in government spending causes private investment to be “crowded in” rather than “crowded out.” In this case consumption is crowded out. 5.

Monetary policy affects consumption most directly by changing the timing of household spending. For households with assets, lower interest rates also make their assets worth more, creating a windfall of greater wealth. Households spend a much smaller fraction of wealth gains than of income gains.

An increase in the price level (i.e., inflation), ceteris paribus, will cause an increase in average interest rates in an economy. In contrast, a decrease in the price level (deflation), ceteris paribus, will cause a decrease in average interest rates in an economy.

Those with large loans must use a larger proportion of their income to pay interest on debt when the interest rate rises. Statistics show that the more people earn, the higher their loans. However, people with high incomes have proportionately more savings. Young people often have large mortgages and student loans.

A monetary policy that lowers interest rates and stimulates borrowing is known as an expansionary monetary policy or loose monetary policy. Conversely, a monetary policy that raises interest rates and reduces borrowing in the economy is a contractionary monetary policy or tight monetary policy.

Monetary Policy’s Impact on Interest Rates For instance, open market purchases of US Treasury bonds by the Fed don’t just boost the money supply; they also tend to reduce short-term interest rates by boosting the amount of liquidity in the economy.

The followings are the disadvantages of expansionary monetary policy: Consumption and investment are not solely dependent on interest rates. If the interest rate is very low then it cannot be reduced more thus making this tool ineffective. The banks’ Standard variable rate didn’t reduce as much as the base rate.

If interest rates are higher than the equilibrium where supply equals demand, there will be excess supply in the market. At the same time, a low interest rate tends to attract a lot of borrowing (larger quantity demanded) The interest rate will rise to equilibrium as borrowers compete for the loanable funds.

Supply-side policies are government attempts to increase productivity and increase efficiency in the economy. Free-market supply-side policies involve policies to increase competitiveness and free-market efficiency. For example, privatisation, deregulation, lower income tax rates, and reduced power of trade unions.

The disadvantages

• However, supply-side policy can take a long time to work its way through the economy.
• In addition, supply-side policy is very costly to implement.
• Furthermore, some specific types of supply-side policy may be strongly resisted as they may reduce the power of various interest groups.

Critics of supply-side policies emphasize the growing federal deficits, increased income inequality and lack of growth. They argue that the Laffer curve only measures the rate of taxation, not tax incidence, which may be a stronger predictor of whether a tax code change is stimulative or dampening.
