Goldman Sachs Sees Short-Term Bond Volatility Rising After Fed Chair Warsh's Hawkish Debut

Goldman Sachs Asset Management (GSAM) predicts increased volatility for short-term U.S. Treasuries but greater stability for long-term bonds following Federal Reserve Chair Kevin Warsh's first hawkish rate decision meeting. GSAM attributes this to Warsh's "unambiguous hawkish signal" prioritizing inflation suppression, which surprised markets and prompted immediate adjustments to rate hike expectations. Market data now shows an over 80% probability of a Fed rate hike by September 2026, with some pricing in multiple hikes by October, a significant shift from earlier expectations of a December hike. The 2-year Treasury yield surged 13 basis points on June 17, 2026, marking its largest single-day increase since April 2025 and matching the biggest jump on an FOMC decision day since 2008. This short-end volatility is driven by Warsh's emphasis on inflation, reduced forward guidance, and data-dependent policy. Conversely, the 30-year Treasury yield fell to a two-month low on June 18, 2026, as investors anticipate Warsh's aggressive inflation control will stabilize long-term price expectations and potentially enhance long-term bond appeal.
