Mexico Inflation Miss Lowers Bar for Banxico Cut

The Mexican peso has been this year's best-performing major currency, underpinned by a nominal rate differential exceeding 600 basis points over the Federal Reserve's upper bound. Carry traders have piled into MXN on that differential alone. If Banxico cuts rates sooner than the Fed, that gap shrinks – and the trade begins to unwind.

USD/MXN has traded in a tight 16.80–17.20 range for weeks. A one-basis-point miss on a quincenal print is not enough to break that range. The better market read focuses on positioning. Crowded carry trades are vulnerable to a catalyst. A series of low inflation prints would increase the risk of a snapback in USD/MXN.

Real yields temper that risk. Mexico's 10-year real yield sits near 7%, above its pre-pandemic average. Even after a 25 bp Banxico cut, the peso would still offer the highest carry among G10-EM crosses. The unwind risk is real, the bar for a sustained MXN selloff is high.

Next Decision Point: May CPI and Policy Signal

The next catalyst is the May headline CPI print, due in early June. If that confirms the quincenal trend – or prints below the 4.5% year-over-year median – Banxico will face pressure to signal a cut at its June 27 meeting. If inflation holds, the policy path remains unchanged, and the peso stays in its current range.

USD/MXN traders should watch two levels:

• A break above 17.20 would signal that carry trade positioning is cracking.
• A move below 16.80 would indicate that the real yield argument still dominates.
