Increasing Interest Rates as a Contrary Measure to Curb Inflation - Examining Methods and Consequences
In an economy experiencing high inflation, central banks often resort to a contractionary monetary policy to cool things down. This policy aims to reduce the growth rate of the money supply, thereby weakening aggregate demand and ultimately lowering inflation.
A contractionary monetary policy is implemented through several means. Central banks can raise the policy rate, the interest rate for short-term borrowings that has become the primary monetary policy tool at several central banks. This move makes borrowing more expensive, influencing aggregate demand and consumption and investment behavior.
Central banks also conduct open market operations, selling government debt securities to commercial banks. This action reduces the money supply, encouraging interest rates to rise. Another instrument used is increasing the reserve requirement ratio, which forces commercial banks to set aside a larger portion of deposits as reserves, thereby reducing the amount of money they can lend.
When the inflation rate deviates from the central bank's target, it intervenes in the economy. Its aim is to reduce pressure caused by high inflation and cool the economy. To avoid overheating, the central bank will adopt a contractionary monetary policy during an overheated economy, usually at the end of the expansion stage before the peak.
Rising interest rates make loans more expensive for households, causing them to delay purchasing durable items such as homes and cars. Businesses, too, reduce investment because capital costs are more expensive, and demand for goods and services weakens. This weakening of aggregate demand occurs because households reduce consumption, and businesses reduce capital investment.
The contractionary monetary policy reduces the rate of inflation, particularly demand-pull inflation, by creating an excess supply that pushes prices down. However, it also leads to slower economic growth. As demand weakens, producers also moderate the pace of their production, leading to slower economic growth.
It's important to note that the central bank has the power to shift from a contractionary policy to an expansionary one when the economy requires it. For instance, the European Central Bank (ECB) conducted a contractionary monetary policy through a series of rate hikes, but later paused its rate increases and started in late 2024 and through 2025 to lower its key interest rates, indicating a shift from a contractionary to a more neutral or easing stance.
In contrast, expansionary monetary policy is used during weak growth, such as during recessions, to stimulate economic growth by expanding the money supply and encouraging aggregate demand.
In conclusion, contractionary monetary policy is a vital tool for central banks to manage inflation and maintain a healthy economy. By understanding this policy and its implications, individuals can make informed decisions about their consumption and investment behaviour.
