Base rates

What Are Base Rates?

Base rates, often referred to as policy rates, are the benchmark interest rates set by a nation's central bank. These rates represent the cost at which commercial banks can borrow money directly from the central bank. As a cornerstone of monetary policy, the base rate serves as a critical tool for influencing broader economic conditions, including inflation, lending rates, and savings rates. By adjusting the base rate, a central bank aims to manage the money supply, stimulate or cool down economic activity, and maintain price stability.

History and Origin

The concept of a central authority influencing a nation's money supply and interest rates has evolved over centuries. Early forms of central banking emerged with institutions like the Bank of England, founded in 1694. However, the modern understanding of base rates as a primary monetary policy tool solidified in the 20th century. In the United States, the Federal Reserve System was established in 1913, following a series of financial panics that highlighted the need for central control over the monetary system to mitigate financial crises. The Federal Reserve's ability to adjust its discount rate and engage in open market operations began to take shape in the 1920s as a means to achieve macroeconomic objectives. For instance, the Federal Reserve actively uses its policy tools to influence borrowing costs and economic activity.19,18

Across the Atlantic, the Bank of England's Base Rate became a focal point for the UK economy. It determines the interest rate the Bank of England pays to commercial banks that hold money with it, and in turn, influences the rates those banks charge for loans or pay on savings.17,16 The evolution of central banks and their use of base rates reflects a continuous effort to achieve macroeconomic stability, particularly after periods of high inflation in the 1970s and 1980s led to a widespread consensus on the importance of price stability.15

Key Takeaways

  • Base rates are the benchmark interest rates set by a nation's central bank.
  • They influence commercial bank lending rates and savings rates, impacting consumers and businesses.
  • Central banks adjust base rates as a primary tool of monetary policy to manage inflation and promote economic growth.
  • Changes in base rates can affect mortgage payments, loan costs, and investment returns.
  • The effectiveness of base rate changes can be influenced by various economic factors and the broader financial environment.

Interpreting the Base Rate

The base rate provides a clear signal about a central bank's stance on monetary policy. A higher base rate generally indicates a tightening of monetary policy, intended to curb inflation by making borrowing more expensive and saving more attractive. Conversely, a lower base rate signals an easing of monetary policy, designed to stimulate economic growth by reducing borrowing costs and encouraging spending and investment.

Individuals and businesses interpret changes in the base rate to make financial decisions. For example, a rise in the base rate typically translates to higher lending rates for mortgages, personal loans, and business credit, while also potentially increasing returns on savings accounts.14 Conversely, a reduction in the base rate makes borrowing cheaper and can reduce the interest earned on savings. The central bank's communication around base rate decisions, including the rationale and future outlook, is closely monitored by financial markets and the public.

Hypothetical Example

Consider a hypothetical scenario in the country of "Diversifia," where the central bank, the Diversifia Reserve, has maintained a base rate of 2% for several years. The economy has been experiencing steady economic growth, but recent data indicate a rise in inflation above the central bank's target.

To address this, the Diversifia Reserve's Monetary Policy Committee decides to increase the base rate by 0.50% to 2.5%. This decision aims to make borrowing more expensive, thereby reducing demand and cooling inflationary pressures.

  • Impact on Borrowers: A homeowner in Diversifia with a variable-rate mortgage linked to the base rate will likely see their monthly payments increase. For instance, if their mortgage rate was 2% plus the base rate (total 4%), it would now become 2% plus the new base rate of 2.5% (total 4.5%). Similarly, businesses seeking loans for expansion might face higher interest costs, potentially delaying or scaling back investment.
  • Impact on Savers: Individuals with savings accounts linked to the base rate would likely see a slight increase in their savings rates, making saving more appealing.
  • Broader Economic Effect: The Diversifia Reserve anticipates that this increase in the base rate will temper consumer spending and credit growth, gradually bringing inflation back towards its target without significantly hindering long-term economic stability.

Practical Applications

Base rates are integral to the functioning of modern financial systems and have several practical applications across various sectors:

  • Commercial Banking: Commercial banks use the base rate as a reference point for setting their own lending rates for mortgages, business loans, and consumer credit products. They also determine savings rates based on the base rate, influencing depositor behavior.
  • Mortgage Market: For many homeowners, particularly those with variable or tracker mortgages, changes in the base rate directly impact their monthly mortgage payments. A rise in the base rate can lead to increased housing costs, while a fall can make mortgages more affordable.13,12
  • Investment Decisions: Investors monitor base rate movements closely as they can influence bond yields, stock market performance, and currency values. For instance, higher base rates might make bonds more attractive relative to equities.
  • Government Policy: While base rates are primarily a tool of monetary policy, they interact with fiscal policy. Government borrowing costs can be influenced by the central bank's rate decisions.
  • International Trade: Differences in base rates between countries can affect exchange rates, influencing the competitiveness of exports and imports. High base rates might attract foreign investment, strengthening the domestic currency.

Central banks, such as the Bank of England, frequently explain how their base rate decisions impact the broader economy and financial landscape.11

Limitations and Criticisms

While base rates are a powerful monetary policy tool, they are not without limitations and criticisms.

One significant limitation is the "zero lower bound" (ZLB) or "effective lower bound," where nominal interest rates cannot effectively be cut below zero. When the base rate approaches or hits zero, the central bank's traditional ability to stimulate the economy by cutting rates is constrained. This has led central banks to employ unconventional policies like quantitative easing to provide further liquidity and lower long-term rates.10

Another criticism centers on the potential for delayed or uneven impacts. Changes in the base rate do not immediately translate into changes in economic growth or inflation. There is often a lag, making it challenging for central banks to perfectly time their interventions. Furthermore, the impact can be uneven, affecting different sectors or groups within an economy differently. For example, homeowners with variable-rate mortgages feel the immediate pinch of a rate hike, while those on fixed rates might be unaffected for a period.

The independence of a central bank in setting base rates, while generally seen as crucial for price stability, can also draw political pressure, especially during periods of slowing economic growth or rising unemployment.9,8 Critics sometimes argue that central bank policies, including base rate decisions, can be overly focused on inflation control at the expense of other objectives like employment, or that their communication can be unclear.7 The Brookings Institution has examined how central bank frameworks may have contributed to delayed responses to surging inflation, particularly concerning the use of forward guidance.6

Base Rates vs. Federal Funds Rate

While "base rate" is a general term referring to a central bank's primary policy rate, the "Federal funds rate" is the specific equivalent in the United States. Both represent the target rate for overnight interbank lending, but their naming conventions and the specific institutions that set them differ.

The base rate (e.g., Bank of England Base Rate) is the official interest rate set by the central bank of a country (e.g., the Bank of England in the UK) that influences other interest rates in the economy. It is the rate at which commercial banks can borrow from the central bank.

The Federal funds rate is the target interest rate set by the Federal Open Market Committee (FOMC) of the Federal Reserve in the United States. It is the rate at which commercial banks lend their excess reserves to other banks overnight. The Federal Reserve influences this rate through open market operations, primarily by buying or selling government securities. While the mechanism for achieving the target rate differs slightly, both the base rate and the Federal funds rate serve as the primary short-term policy rate influencing the broader cost of money in their respective economies. The aim of both is to manage liquidity, control inflation, and promote stable economic growth throughout the business cycle.

FAQs

What happens when the base rate goes up?

When the base rate goes up, commercial banks typically increase their own lending rates for products like mortgages, personal loans, and credit cards.5 This makes borrowing more expensive for consumers and businesses, which can discourage spending and credit growth, aiming to cool down an overheating economy and curb inflation.4

How often does the base rate change?

The frequency of base rate changes depends on the central bank's scheduled meetings and economic conditions. For example, the Bank of England's Monetary Policy Committee reviews its Base Rate about eight times a year.3 The U.S. Federal Reserve's Federal Open Market Committee (FOMC) also meets eight times annually to discuss the Federal funds rate. However, a decision to change the rate is not made at every meeting; it depends on the economic outlook.

Does the base rate directly affect my mortgage?

The direct impact on your mortgage depends on its type. If you have a variable-rate or tracker mortgage, your payments will likely change in line with base rate adjustments. For fixed-rate mortgages, your payments remain constant for the fixed period, but the rate you get when you remortgage will be influenced by the prevailing base rate.2

Why is the base rate important for the economy?

The base rate is important because it is a key determinant of the cost of money in an economy. It influences all other interest rates, affecting everything from consumer spending and business investment to inflation and unemployment. By adjusting the base rate, the central bank can manage the pace of economic growth and maintain price stability.1
