The Mexican peso weakened against the dollar on Wednesday as investors kept their focus on Kevin Warsh’s Jackson Hole speech, with the currency moving in step with shifting expectations for U.S. monetary policy and the widening yield premium on American assets.
Mexican peso weakens before Jackson Hole speech
The peso’s retreat matters because Mexico’s currency has been one of the clearest pressure points for global macro traders this year: when U.S. yields rise or the dollar firms, the peso is often among the first emerging-market currencies to adjust. That makes it a key barometer for risk appetite, carry-trade positioning and the outlook for capital flows into Mexico, which has been drawing support from nearshoring and export-linked investment.
On the rates side, the latest move came against a backdrop of U.S. Treasury yields edging higher. The two-year note was at 4.24%, up sharply from 1.7% at the end of 2008 and underscoring how much policy-rate expectations have re-priced over time, while the 10-year yield stood at 4.74%, leaving the curve still elevated by historical standards. Forecasts for the next session pointed to only modest further firming in both maturities, suggesting traders were waiting for fresh guidance rather than making an aggressive macro bet before Jackson Hole.
That caution has spilled into foreign exchange. The peso traded around 16.96 per dollar on August 27, after touching 16.94 earlier in the week, compared with 17.54 on July 20 and 18.68 in early November last year. The move has taken the pair below its 200-day moving average of 17.54 and kept it under the 50-day average of 17.32, while the relative strength index has fallen to 21.3, a level that typically points to technically oversold conditions. The broad dollar fund UUP, meanwhile, held near 28.00, with its 50-day average at 28.27, reinforcing the view that the dollar remains the cleaner trade until the Federal Reserve’s next signal becomes clearer.
For investors, the key question is whether Warsh — widely watched for any comment on policy independence, inflation and the timing of rate cuts — reinforces the idea that U.S. real yields can stay high for longer. A more hawkish message would tend to support the dollar and keep pressure on the peso, even if Mexico’s domestic fundamentals remain relatively stable. A softer tone, by contrast, could revive carry demand for the peso and other higher-yielding currencies.
The move also has direct implications for Mexico’s economy. A weaker peso can help exporters and border manufacturers by improving their competitiveness in dollar terms, but it can also feed imported inflation and complicate the central bank’s task if the slide persists. That balance is especially important for Mexico’s maquila sector, which is tied closely to U.S. demand and trade flows.
The broader narrative remains the same: the peso is less a local story than a live referendum on U.S. rates, global risk sentiment and how much room emerging-market currencies have to rally when the dollar is on the defensive. Until Jackson Hole resolves some of that uncertainty, traders are likely to keep trimming risk rather than chasing the peso higher.
