A quieter U.S. Federal Reserve under potential chair Kevin Warsh could spark market volatility and push interest rates higher, according to Blake Gwinn, head of U.S. rates strategy at RBC Capital Markets.
Warsh's Policy Shift
Gwinn warned that Warsh's approach, which favors less frequent communication and a more hands-off style, may leave investors guessing about the central bank's next moves. This uncertainty could amplify market swings and lead to higher long-term borrowing costs.
"The risk is that markets misinterpret the Fed's intentions or overreact to sparse guidance," Gwinn said in an interview. "That could mean higher term premiums as investors demand compensation for greater uncertainty."
Impact on Borrowing Costs
Higher term premiums would push up yields on Treasury bonds, making mortgages, corporate loans, and other debt more expensive. The 10-year Treasury yield could rise by 20 to 30 basis points under a more opaque Fed, Gwinn estimated.
This contrasts with the current Fed under Jerome Powell, which has emphasized clear forward guidance and regular press conferences to manage market expectations.
Market Reaction
Markets have already priced in a more cautious Fed, but a shift to less communication could disrupt those assumptions. The S&P 500 fell 1.2% on Monday as speculation about Warsh's nomination intensified.
"Investors crave predictability from the Fed," Gwinn added. "Any departure from that norm could trigger a repricing of risk across asset classes."
The Federal Reserve declined to comment on the speculation. Warsh, a former Fed governor, has not publicly outlined his policy plans.
