Mexican Peso Rises to Two-Year High on U.S. Treasury Buybacks

Boosted by the U.S. Treasury's expanded long-term bond buyback program, U.S. Treasury yields retreated, dragging the dollar lower and lifting the Mexican peso, with USD/MXN trading at 16.96571, near two-year highs.

**Expanded Buybacks Ease Yield Pressure**

The U.S. Treasury doubled its long-term bond buyback scale, pushing Treasury yields down from recent highs. The Treasury market had been under sustained pressure, with the 30-year yield hitting its highest level since 2007 and the 10-year yield rising more than 0.5 percentage points over 12 weeks. The expanded buybacks provided marginal support to the market, weakening the dollar and broadly benefiting emerging market currencies.

**Peso Strength but Sustainability in Question**

The peso's rebound is directly driven by lower Treasury yields and a softer dollar, rather than a significant improvement in Mexico's domestic fundamentals. Market participants note that upward pressure on Treasury yields has not been fundamentally resolved, with rising energy prices and inflation expectations still supporting U.S. bonds. George Catrambone, Head of Fixed Income Americas at DWS, believes that only a de-escalation of conflicts, a recovery in energy supply, or signs of an economic downturn prompting market bets on Fed rate cuts could bring the 10-year Treasury yield back to previous levels.

**Short-Term Direction Still Tied to Treasuries**

The peso's near-term trajectory remains highly dependent on Treasury yields and the dollar's direction. If the U.S. Treasury further expands buybacks or signals clearer policy moves, the peso could sustain its strength; conversely, if yields resume their climb, the peso's gains may face pullback pressure. Markets will closely monitor Treasury auction demand and marginal shifts in Fed policy expectations.
