Fed Chair Kevin Warsh is actually managing U.S. debt costs not inflation, economist says, as interest rates threaten to top GDP growth soon

Economist Robin Brooks argues that Federal Reserve Chair Kevin Warsh's mixed statements about his stance on monetary policy should not be seen as hawkish or dovish. Instead, Brooks suggests that Warsh's actions are focused on managing long-term yields, which are directly tied to the precarious state of U.S. debt. With debt costs already exceeding defense spending and projected to reach $1 trillion in fiscal year 2026, Warsh's primary concern appears to be keeping borrowing costs manageable.

This approach has involved interventions in the bond market and currency markets, as seen in Treasury Secretary Scott Bessent's surprise buyback of long-term bonds and intervention in the yen market. However, Brooks cautions that these efforts may lead to fiscal dominance, where high debt and deficits overshadow the Fed's ability to independently tackle inflation.

While Bank of America economists acknowledge that the U.S. can still avoid a debt spiral if nominal GDP growth outpaces interest rates, rising yields have surpassed long-term estimates, raising concerns. If yields continue to rise beyond the current levels, long-term nominal GDP growth could be outpaced as early as 2028, highlighting the potential risks of the situation.
