If you’re like most people, you probably don’t spend much time thinking about monetary policy.

You might have a vague idea that it has something to do with interest rates, inflation, and the economy, but you’re not sure how it affects your daily life.

And you’re not alone. Even the experts who make monetary policy decisions face a lot of uncertainty and challenges in their job.

In this blog post, we’ll take a closer look at what monetary policy is, why it matters, and how it works in practice. We’ll also explore some of the current issues and dilemmas that policymakers face in a changing and unpredictable world. By the end of this post, you’ll have a better understanding of the complex and fascinating world of monetary policy, and how it impacts you and your finances.

This post is encouraged by the speech titled "Signal versus noise" - by Ben Broadbent (Deputy Governor of Bank of England) Given at the London Business School.

What is monetary policy and why does it matter?

Monetary policy is the set of actions and tools that a central bank, such as the Bank of England, uses to influence the amount of money and credit in the economy. The main goal of monetary policy is to keep inflation low and stable, which helps to promote economic growth and stability.

Inflation is the general increase in the prices of goods and services over time. A moderate and predictable rate of inflation is good for the economy, because it encourages people to spend and invest, and allows businesses to adjust their prices and wages. However, if inflation is too high or too low, or changes unexpectedly, it can cause problems for consumers, workers, and firms. For example, high inflation erodes the purchasing power of money, reduces the real value of savings and debts, and creates uncertainty and confusion. Low inflation, on the other hand, can signal weak demand, discourage investment and innovation, and increase the risk of deflation, which is a harmful and persistent fall in prices.

To keep inflation under control, the central bank uses its main policy tool, which is the Bank Rate. This is the interest rate that the central bank charges commercial banks for borrowing or depositing money with it. The Bank Rate influences the interest rates that banks charge their customers for loans and mortgages, and that they pay them for savings and deposits. By changing the Bank Rate, the central bank can affect the cost and availability of money and credit in the economy, and thus influence the level of spending and saving by households and businesses.

The central bank also uses other tools, such as quantitative easing (QE) and forward guidance, to support its monetary policy objectives. QE is the process of creating new money and using it to buy assets, such as government bonds, from financial institutions. This lowers the yields on these assets, which reduces the borrowing costs for the government and other borrowers, and increases the amount of money and credit in the economy. Forward guidance is the communication of the central bank’s expectations and plans for future monetary policy, which helps to shape the expectations and behaviour of market participants and the public.

How does monetary policy work in practice?

In the UK, monetary policy is decided by the Monetary Policy Committee (MPC), which is a group of nine experts appointed by the government and the Bank of England. The MPC meets eight times a year to assess the current and future state of the economy, and to decide on the appropriate level of the Bank Rate and the size of QE. The MPC’s decisions are based on a range of information and analysis, including official statistics, business surveys, market indicators, and economic models.

The MPC’s main target is to keep inflation at 2% per year, as measured by the Consumer Prices Index (CPI). This target is set by the government and reflects the optimal rate of inflation for the UK economy. The MPC also has to consider the impact of its decisions on the wider objectives of the government, such as economic growth, employment, and financial stability.

However, the MPC does not have perfect information or control over the economy. There are many factors that can affect inflation, some of which are outside the MPC’s influence, such as changes in oil prices, exchange rates, taxes, and global events. Moreover, there are often uncertainties and trade-offs involved in making monetary policy decisions, such as:

  • The lag between monetary policy actions and their effects on inflation. It can take up to two years for a change in the Bank Rate or QE to fully affect inflation, because of the time it takes for people and businesses to adjust their spending and saving decisions, and for prices and wages to change. This means that the MPC has to base its decisions on forecasts and expectations of future inflation, rather than current inflation, which can be subject to errors and revisions.
  • The difficulty of identifying the underlying causes of economic fluctuations. The MPC has to distinguish between different types of shocks that can affect the economy, such as demand shocks, supply shocks, mark-up shocks, and NAIRU shocks. These shocks have different implications for inflation and output, and require different policy responses. For example, a demand shock, such as a rise in consumer confidence, increases both inflation and output, and may call for a tighter monetary policy to prevent overheating. A supply shock, such as a technological improvement, lowers inflation and raises output, and may call for a looser monetary policy to support growth. A mark-up shock, such as a change in firms’ pricing power, affects inflation but not output, and may require a neutral monetary policy to avoid unnecessary volatility. A NAIRU shock, such as a change in the unemployment rate consistent with stable inflation, affects both inflation and output, but in opposite directions, and may pose a trade-off for monetary policy between stabilising inflation and supporting growth.
  • The uncertainty about the behaviour of the supply side of the economy. The MPC has to estimate the potential supply of the economy, which is the level of output that can be produced without generating inflationary pressure. The potential supply depends on factors such as productivity, labour force participation, and the NAIRU, which can vary over time and are hard to measure. If the MPC overestimates the potential supply, it may keep monetary policy too loose and allow inflation to rise above the target. If it underestimates the potential supply, it may keep monetary policy too tight and prevent the economy from reaching its full potential.
  • The trade-off between timeliness and accuracy of information. The MPC has to rely on a range of information sources to assess the state of the economy, such as GDP, employment, wages, and inflation. However, these data are not always available, accurate, or complete. Some data are subject to revisions, measurement errors, or sampling errors, which can change the picture of the economy over time. Some data are subject to lags, which means that they reflect the past rather than the present or the future. Some data are subject to noise, which means that they contain temporary or transitory movements that do not reflect the underlying trends. The MPC has to weigh the benefits and costs of using different types of information, and decide how much weight to put on them. For example, GDP growth is a timely and comprehensive measure of economic activity, but it can be affected by both demand and supply shocks, and can be revised significantly over time. Unemployment is a more direct measure of spare capacity in the labour market, but it can be affected by changes in the NAIRU, and can lag behind output growth. Wage growth and services inflation are more direct measures of domestic inflationary pressure, but they can be affected by other factors, such as import prices, taxes, and expectations, and can lag behind changes in spare capacity.

These challenges and dilemmas mean that monetary policy is not a simple or mechanical process, but a complex and judgemental one. The MPC has to balance the risks and uncertainties, and make the best possible decisions based on the available information and analysis. The MPC also has to communicate its decisions and reasoning to the public and the markets, and explain how it will respond to new information and developments.

Summary

To wrap up, here are the key takeaways from this post:

  1. Monetary policy is a crucial tool used by central banks to manage inflation and promote economic stability.
  2. The Monetary Policy Committee (MPC) at the Bank of England uses a range of indicators to make informed decisions.
  3. Uncertainty is a constant in monetary policy, and the MPC must balance timeliness and accuracy of information.
  4. Communication is key in monetary policy, both in terms of transparency with the public and clear guidelines for markets.
  5. Staying informed and engaged with monetary policy can help individuals make better financial decisions.

Remember, monetary policy might seem complex, but it doesn’t have to be inaccessible. By breaking it down, we can all gain a better understanding of the financial forces that shape our world.
