What is Monetary Policy?
Monetary policy refers to the tools and strategies used by central banks to control the supply of money and the cost of borrowing. The primary conventional tool is setting short-term interest rates. The US Federal Reserve targets the federal funds rate, the European Central Bank sets the refinancing rate, and the Bank of Japan controls the overnight call rate. When conventional tools are insufficient, central banks turn to unconventional measures like quantitative easing.
Monetary Policy and Portfolio Strategy
Interest rate decisions ripple through every asset class. Rate cuts generally boost stock prices by lowering discount rates and borrowing costs, while rate hikes have the opposite effect. Bond prices move inversely to yields, so rate hike cycles reduce existing bond values. The yield curve shape, influenced by rate expectations, signals economic outlook. An inverted yield curve has preceded every US recession since 1955.
Key Considerations
Monetary policy operates with a lag of 6-18 months, meaning today's rate decisions affect the economy well into the future. Central bank communication (forward guidance) often moves markets more than actual rate changes. Investors should focus on the trajectory and terminal rate of policy cycles rather than reacting to individual meetings.
