USDMXN opened last Monday at 16.8831 and closed Friday at 16.9673. That is a net gain of 0.0842, roughly 0.50% on the week, with the dollar taking back ground after a soft midweek dip. The bulk of the move came on Thursday, when price ran from a 16.8802 low up to 17.0115 before closing at 16.9820. Friday gave a little of that back. The weekly low at 16.8712 was set on Wednesday, so the full range last week ran from 16.8712 to 17.0115.
The Federal Funds Rate decision on Wednesday 16 September at 18:00 is the event that matters. Consensus in the bundle is 4.00%, up from the previous 3.75%. That decision arrives alongside the FOMC Statement and the FOMC Economic Projections, with the press conference at 18:30. For a high-carry pair like USDMXN, the projections carry as much weight as the rate itself, because the dot path shapes how much of the peso's yield advantage survives into next year.
Two other US prints frame the Fed. Retail Sales lands Wednesday at 12:30, forecast 0.8% after a previous reading of -0.6%, with Core Retail Sales forecast at 0.5% against -0.3% previously. Unemployment Claims follow Thursday at 12:30 with a forecast of 209K versus 206K prior, and the Philly Fed Manufacturing Index the same morning is forecast to drop to 28.9 from 47.4. Outside the dollar, the Bank of England decides Thursday at 11:00 with the Official Bank Rate forecast to hold at 3.75%, and the Bank of Japan announces Friday at 02:30 with the policy rate forecast below 1.25% against below 1.00% previously. Those two set the broad risk tone that emerging-market currencies trade against. Open an LHFX account to trade USDMXN through this week's Fed decision.
If the Fed delivers the forecast 4.00% and the projections point to more tightening, the dollar side of the pair gets the rate support and last week's 17.0115 high becomes the obvious reference on the upside. If the hike comes with a softer statement or a press conference that plays down further moves, the peso's carry appeal is the cleaner story and Wednesday's 16.8712 low from last week comes back into focus.
If Retail Sales beats the 0.8% forecast ahead of the decision, expect the dollar bid to build into the announcement rather than wait for it. A miss against the -0.6% base sets up a choppier session where price hovers into 18:00. Watch the broad dollar through EUR/USD as a cross-check. If the dollar strength is broad rather than peso-specific, USDMXN and the euro pair should move in step, and a divergence points to something local in the peso.
The BOJ on Friday is the wildcard for risk appetite. A hawkish surprise from Tokyo tends to pull carry trades in, and high-yield currencies like the peso are usually first to feel it. A hold-and-wait tone leaves the week's direction with whatever the Fed said two days earlier.
Retail positioning sits at 61.5% long and 38.5% short as of Monday morning. That is a clear skew toward more dollar strength against the peso, and it follows a week that closed higher, so the crowd is trading with the recent move rather than against it. A crowded long book going into a binary event cuts both ways. If the Fed confirms the hike path, those positions get paid. If the statement lands softer, the unwind tends to be faster than the build, because there are more positions on one side to flush.
Last week's high at 17.0115 is the first reference, and it sits just above the 17.00 round number, which makes that zone a natural place for reactions. Below, Friday's close at 16.9673 is the short-term pivot, and Wednesday's 16.8712 low marks the base of last week's range. If price holds above 16.9673 through the Monday and Tuesday sessions, the 17.00 area is the level the market is testing into the Fed. If it loses that pivot before Wednesday, the 16.8712 low is the reference on the way down. These are reference levels drawn from last week's price action, not entry signals.
