The U.S. Federal Reserve raised its short-term interest rate, the federal funds rate, by 25 basis points on September 16, marking the first increase in three years.
The rate moved from a range of 3.5%-3.75% to 3.75%-4%.
The decision by the Federal Open Market Committee, led by Chair Kevin Warsh, aimed to combat persistent inflation.
U.S. inflation, measured by the Consumer Price Index, stood at 3.4% in August, remaining above the Federal Reserve's 2% target.
The increase in interest rates occurred amidst rising U.S. public debt and increasing 10-year U.S. Treasury bond yields.
Detailed Insights:
The federal funds rate is broadly comparable to the Reserve Bank of India's repo rate, serving as a key policy tool.

Long-term bond yields, including the 10-year U.S. Treasury bond, crossed 5% on September 14, driven by inflation fears and government borrowing.
The U.S. public debt-to-GDP ratio reached 122.6% in the first quarter of 2026, nearly double what it was two decades prior.
