Bond investors, uncertain about the outlook for Federal Reserve tightening, have been paying more to protect against the possibility of a sharp rise in U.S. interest rates. U.S. financial markets are grappling with questions about whether new Fed Chair Kevin Warsh will keep the central bank focused on containing inflation, which could require rate hikes, or bow to President Donald Trump's repeated calls for rate cuts.
Activity in the interest rate options market has shifted in recent months, with growing demand for a specific type of swaption, or an option on interest rate swaps, that would profit if long-term borrowing costs rise. Some are hedging against the 10-year swap rate reaching 6%, more than 200 basis points higher than today's 4.23% level.
