How Central Banks Move Markets

7 Ogo

Central banks captivate traders across the world because of their immense importance: they are the institutions responsible for managing a nation's monetary system. One change by a major central bank can send markets moving by directly impacting the cost to borrow and the value of money within a nation. Most recently, the Bank of Japan's decision to hike interest rates, reflecting a shift in its monetary policy to address inflationary pressures, sent a shockwave throughout the markets, which can especially be seen on the USDJPY. In this post, we’re going to dive into the basics of central banks, why they matter, and how new traders can understand them.

What Do Central Banks Do?

The primary duties of a central bank include setting monetary policy, controlling inflation, ensuring high employment levels, and maintaining currency stability. They can also issue currency to control money supply, function as the bank for the government, regulate the credit system, oversee commercial banks, manage exchange reserves, and act as lenders of last resort. In short, central banks do a lot! They manage a nation’s money, and their actions can move markets.

The Primary Tool of Central Banks

Central banks perform a delicate balancing act to manage economic growth and control inflation. Their primary tool for doing this is setting interest rates and communicating that to the markets. For example, if the economy grows too quickly, inflation can rise, making prices too high for consumers. Conversely, slow economic growth can lead to higher unemployment. The main tool central banks use to maintain this balance is the base interest rate, which they control and communicate through meetings, announcements, and economic calendars. By raising or lowering these rates, central banks influence economic activity, either encouraging spending and investment or promoting saving.

Why Interest Rates Matter

Interest rates impact the economy by encouraging either saving or spending. Lower interest rates make borrowing cheaper, prompting businesses to invest and individuals to buy homes, stimulating economic growth. However, if growth becomes excessive, inflation can surge, leading to reckless spending and potential economic instability. Raising interest rates can slow down economic activity, reduce inflation, and discourage borrowing, ensuring a more stable economy. Once again, central banks need to find a fine balance.

How Fed Decisions Impact Markets

Remember we mentioned the Bank of Japan earlier in this post? Well, by raising interest rates, they signaled to the market a possible new direction in controlling inflation not only in Japan, but also those who trade related instruments like Yen-denominated forex pairs from USDJPY to GBPJPY. Higher interest rates attract investors seeking better returns, increasing demand for that country's currency. Conversely, lower interest rates can lead to currency depreciation. More importantly, traders may also use strategies like carry trades, buying currencies with high-interest rates and selling those with low rates to profit from the interest rate differential, highlighting the interconnectedness of central bank policies and global financial markets. So, when interest rates change, it can have sweeping impacts across markets.
