Why are short term rates volatile?

Short-term interest rates are volatile primarily due to changes in monetary policy, economic indicators, and market sentiment. Central banks, like the Federal Reserve, may adjust rates in response to inflation, employment data, or economic growth, leading to fluctuations in borrowing costs. Additionally, market participants react to news and economic forecasts, causing rapid shifts in demand for short-term debt instruments. This responsiveness to both policy and market conditions contributes to the inherent volatility of short-term rates.
