Fed Chair Warsh Focuses on Yield Curve Management Amid Rising Debt Costs
Analysts say Federal Reserve Chair Kevin Warsh is prioritizing long-term Treasury yield management over inflation concerns as U.S. debt interest payments climb.
Federal Reserve Chair Kevin Warsh has shifted attention from traditional inflation debates to managing the yield curve, according to senior Brookings fellow Robin Brooks. Brooks wrote in a Substack post that the Fed’s actions are driven by the “precarious U.S. debt picture,” with Treasury yields threatening to worsen a debt burden that now exceeds $40 trillion and a fiscal year 2026 interest cost that topped $1 trillion.
Brooks argued that the Fed and Treasury Department appear to be coordinating to stabilize borrowing costs, citing Treasury Secretary Scott Bessent’s surprise buy-back of long-term bonds, which briefly lowered yields, and his intervention in the currency market to support the yen without prompting Japan to sell U.S. debt.
While external factors such as oil price spikes and expectations of renewed conflict in Iran have pushed yields higher, other developments have eased pressure. Concerns about a potential slowdown in the AI-driven growth surge and political instability in France have reduced investor anxiety, allowing Treasury securities to regain appeal and the 10-year yield to fall below 5%.
Brooks concluded that Warsh is neither a hawk nor a dove, but is “trying to keep long-term yields manageable.” He warned that sustained high yields could lead to fiscal dominance, where debt and deficits limit the Fed’s ability to conduct independent monetary policy. The Congressional Budget Office’s scenarios for yields 150 basis points above its baseline project net interest costs rising by $4.9 trillion over ten years and publicly held debt reaching 133% of GDP by 2036. Bank of America analysts noted that under such conditions the effective interest rate on government debt could exceed long-term nominal GDP growth as early as fiscal year 2028.
Despite these risks, nominal GDP growth remains strong, recorded at 5.6% in the third quarter, driven by AI-related activity and elevated inflation. However, Bank of America cautioned that assuming the United States can simply outgrow its debt burden may be overly optimistic.
