Ceasefire sparks FX mean reversion

Ceasefire sparks FX mean reversion. USD/CAD breaks range as CAD lags risk relief. Peso gains big on relief rally.

In my earlier note on post-conflict FX mean reversion, I argued that once the war premium starts fading from energy, the crowded long‑USD trade should begin to unwind. Today’s price action looks like the first chapter of that script: the USD is softer across G10, led by high‑beta rebounders like SEK and NZD, with CHF also firmer, consistent with a broad de‑risking of the conflict premium rather than a single-currency story.

The move lines up with the headlines. The United States and Iran agreed to a two‑week ceasefire framework tied to a reopening of the Strait of Hormuz, after Pakistan pushed for a last‑minute off‑ramp ahead of President Trump’s escalation deadline. Iran’s foreign minister also signaled that transit would be permitted for two weeks, but under coordination with Iran’s armed forces, which is an important nuance for how “open” Hormuz is in practice.

Oil sold off hard on the announcement, with Brent briefly down in the mid‑teens at the lows, while equity futures jumped, a classic relief‑rally mix that typically pressures the USD and supports the most beaten‑down G10 currencies. A useful recap of the immediate FX reaction is below.

It also helps explain why CAD can lag on days like this. When crude is the macro shock absorber on the way up, it can become the headwind in reverse when prices reset lower, even if the broader USD pullback lifts most currencies. That’s one reason I keep coming back to “oil first, FX second” in this episode.

Still, it’s worth separating “risk” from “flows.” A ceasefire window reduces tail risk, but it doesn’t automatically restore full confidence for commercial shipping overnight. The details and execution matter for a real normalization in tanker behavior, not just the headline.

Zooming out, China’s role remains more structural than mentioned on media. China is the dominant buyer of Iran’s exported crude, largely through independent “teapot” refineries in Shandong, and those channels have proven resilient through sanctions and conflict. On the payments side, China’s CIPS system has reported record volumes, which the Atlantic Council’s GeoEconomics Center has flagged as a notable signal alongside broader yuan-settlement narratives, while the system’s own published metrics are available via CIPS.

Bottom line: the ceasefire reduced escalation risk, and markets immediately priced that through lower oil, higher equities, and a softer USD. Whether this turns into a sustained FX mean‑reversion trend will depend on two things that are harder than a headline; whether the truce holds, and whether the physical oil and shipping system actually normalizes.

FX mean reversion on ceasefire

USD/CAD breaks range as CAD lags risk relief

USD/CAD is currently trading near 1.386, after breaking out of a tight consolidation range that had held for three sessions prior to confirmation of the Iran ceasefire. Ahead of the announcement, the pair was locked between roughly 1.389 and 1.393, reflecting headline risk and position-squaring rather than conviction. The ceasefire triggered a clear relief move lower in USD/CAD as broader risk sentiment improved and the USD weakened across G10.

That said, the follow‑through in CAD has been notably muted relative to higher‑beta peers, consistent with the FX mean‑reversion framework outlined in my previous note. While the unwind of geopolitical risk has driven a broader USD pullback, CAD’s lower beta to USD in risk‑on phases, particularly when oil prices are falling rather than rising, continues to limit downside momentum in USD/CAD.

Positioning data reinforces that restraint. Net futures positioning remains slightly bearish at around ‑39k contracts, improved from late‑2025 extremes but still far from signaling enthusiasm for a sustained Loonie rally. Both leveraged funds and asset managers remain cautious, suggesting the latest move reflects macro relief rather than a decisive shift in CAD sentiment.

Domestic fundamentals remain the key constraint. Idiosyncratic Canadian risks, soft data prints and evidence of a stagnant growth backdrop, continue to weigh on CAD relative to peers that benefit more directly from improved global risk appetite. This divergence keeps USD/CAD supported on dips, even as broader mean‑reversion dynamics pressure the USD lower.

Looking ahead, near‑term direction will hinge on U.S. macro releases, including the Fed minutes and the closely watched PCE and CPI inflation reports later this week. A firmer‑than‑expected inflation outcome could temper the USD pullback. On the Canadian side, another soft labor report, particularly if March unemployment rises toward the expected 6.8%, would reinforce the Bank of Canada’s cautious stance and argue for USD/CAD downside remaining gradual rather than directional, despite the improved global risk backdrop.

Sentiment remains slightly bearish

Peso gains big on relief rally

USD/MXN downside momentum has re‑emerged following the confirmation of the Iran ceasefire, with the Mexican peso gaining around 2% against the USD over the past three sessions and the pair now trading near 17.40, its lowest level since early March. This marks a clear reversal from the sharp risk‑off rally that carried USD/MXN from near 17.00 in February to a peak around 18.20 in early March. The pair had been consolidating around 17.80 ahead of the ceasefire, but broader risk relief and a softer USD have allowed MXN to outperform within EM FX.

Despite the improvement in spot performance, caution remains visible beneath the surface. Emerging‑market FX volatility remains elevated and, at times, has traded above G7 volatility, underscoring the fragility of sentiment. The recent peso strength appears more driven by global risk normalization, USD weakness and carry appeal against a rather weak fundamental macro-outlook based on recent data.

Domestic fundamentals remain a limiting factor for sustained MXN appreciation. Recent data have undershot expectations, with private consumption growth slowing to 1.5% and gross fixed investment contracting 3.3% year over year. Combined with Banxico’s recent 25‑bp rate cut, the peso’s yield advantage has narrowed at the margin. While inflation remains relatively high near 4.65%, the central bank’s easing bias highlights the trade‑off between price stability and a cooling growth outlook. As a result, the peso’s recent gains look more cyclical than structural, leaving USD/MXN vulnerable to consolidation rather than a straight‑line extension lower.

Options markets continue to reflect that asymmetry. While the immediate stress has eased, nine‑month and one‑year risk reversals remain elevated, suggesting that investors are still paying a premium for protection against renewed USD strength. This points to lingering concern that geopolitical calm may prove temporary or that global conditions could re‑tighten quickly. For now, big gains on relief rally.
