# Economic growth and interest rates relationship

interest rates, and, in particular, the relationship between variations in interest rates and the rate of economic growth. Is there a positive correlation, as suggested. Interest rates are on the rise, at their highest levels in over 4 years. there is a strong relationship between bond yields and the real economy. PDF | Using time-series and panel data from to , this paper examines the Granger causality relations between GDP growth and real interest rate in.

According to standard economic theory, such slower growth would push down the level of the natural rate of interest. This natural rate, also called the neutral or equilibrium real interest rate, is the risk-free short-term interest rate adjusted for inflation that would prevail in normal times with full employment Williams Moreover, a decline in the natural rate of interest would tend to lower every other real and nominal interest rate in the economy.

Therefore, understanding the linkage between economic growth and the natural rate is crucial for forecasting all types of interest rates.

Indeed, this linkage has been at the center of recent fiscal and monetary policy forecasts. In addition, earlier this year, some Federal Open Market Committee FOMC participants appeared to reduce their estimates of the natural rate of interest because of an expectation of slower growth ahead for potential output.

This Economic Letter examines the linkage between growth and interest rates as embodied in recent projections by FOMC participants, the CBO, and private-sector forecasters. Although forecasts of potential growth or the natural rate are rarely reported, we can construct reasonable proxies from long-run forecasts of GDP growth, the short-term interest rate, and inflation.

In essence, the long-run nature of these forecasts strips out cyclical variation and reveals the fundamental secular trends that underlie the concepts of potential growth and the natural rate of interest. Although in the CBO and FOMC policy projections long-run forecasts of growth and the real interest rate have fallen together, private-sector forecasters do not anticipate a similar dual drop.

In particular, the recent downward revisions in private-sector expectations for long-run growth have been associated with no change in their long-run projections of the real short-term interest rate.

If the private-sector forecasters are correct, this would raise a concern that the CBO and FOMC may have overestimated the effects of slower potential growth toward reducing interest rates, which may introduce some upside risk to CBO and FOMC interest rate projections.

FOMC and CBO projections of growth and interest rates In standard economic theory, the natural interest rate—that is, the short-term real interest rate at which the economy would stay at full employment—is related positively to the growth rate of potential output.

Higher potential growth can affect the real interest rate via two key channels. First, it increases the returns on investment and thus leads to higher investment demand.

Second, because higher growth boosts future earnings, it leads forward-looking households to consume more and save less. The combination of higher investment and lower savings raises the real interest rate. As a result, higher potential growth would be associated with a higher natural rate Laubach and Williams Of course, this simple theory is not definitive, and in the real world, other factors may obscure or overwhelm this relationship, including those highlighted in the recent debate about secular stagnation Summers Most importantly perhaps, in an open economy with international financial flows, the real interest rate is determined by the interaction of growth, saving, and investment at a global level—rather than by developments in any single country.

Because we do not directly observe the natural rate of interest or potential trend growth, we construct proxies from long-run forecasts of real GDP growth and short-term real interest rates. Long-run real GDP growth forecasts are available since Long-run forecasts of the equilibrium real interest rate can be constructed since using long-run forecasts of the nominal federal funds rate and of inflation in the price index for personal consumption expenditures.

We use the average of five- to ten-year-ahead forecasts. We calculate the real interest rate forecast using projections of the three-month Treasury bill rate and of inflation in the consumer price index CPI. Based on historical differences among the data series, we subtract 0.

Since the beginning ofFOMC participants have lowered their projections of the short-term rate from 2.

- Effect of raising interest rates

Echoing the views of FOMC participants, the latest report on the long-term budget outlook from the CBO emphasized that a key factor behind the declining real rate was the decline in potential growth. The two series have a fairly close correlation of 0. Evidence from private-sector forecasts and historical data Are the views of FOMC participants and the CBO about the linkage between long-run growth and interest rates shared by private-sector forecasters?

Sincethe Blue Chip Economic Indicators has reported long-run forecasts from business economists for growth and interest rates. We use the average five- to ten-year-ahead consensus forecasts for real GDP growth and for the short-term real interest rate. If we get lower AD, then it will tend to cause: Lower economic growth even negative growth — recession Higher unemployment. If output falls, firms will produce fewer goods and therefore will demand fewer workers.

Improvement in the current account. Higher rates will reduce spending on imports, and the lower inflation will help improve the competitiveness of exports.

Evaluation of higher interest rates Higher interest rates affect people in different ways. The effect of higher interest rates does not affect each consumer equally.

Those consumers with large mortgages often first time buyers in the 20s and 30s will be disproportionately affected by rising interest rates. For example, reducing inflation may require interest rates to rise to a level that causes real hardship to those with large mortgages. However, those with savings may actually be better off. This makes monetary policy less effective as a macro economic tool. The effect of rising interest rates can often take up to 18 months to have an effect.

However, the higher interest rates may discourage starting a new project in the next year. It depends upon other variables in the economy. At times, a rise in interest rates may have less impact on reducing the growth of consumer spending.

For example, if house prices continue to rise very quickly, people may feel that there is a real incentive to keep spending despite the increase in interest rates. It is worth bearing in mind that the real interest rate is most important. The real interest rate is nominal interest rates minus inflation. It depends whether increases in the interest rate are passed on to consumers.

Banks may decide to reduce their profit margins and keep commercial rates unchanged.

The concern is that after several years of zero interest rates — people have got used to low rates. US interest rates Increased interest rates had a significant impact on US housing market.

Higher mortgage costs led to a rise in mortgage defaults — exacerbated by a high number of sub-prime mortgages in the housing bubble.

In this case, higher interest rates were a significant factor in bursting the housing bubble and causing the subsequent credit crunch. The UK has experienced two major recessions, caused by a sharp rise in interest rates.

In and 81, the UK went into recession, due to the high-interest rates and appreciation in Sterling. If the Central Bank is worried that inflation is likely to increase, then they may decide to increase interest rates to reduce demand and reduce the rate of economic growth. Usually, if the Central Bank increase base rates, it will lead to higher commercial rates too.
