The Big Three
Iran strike reshapes the risk landscape overnight. The coordinated US-Israel attack on Iran killed Ayatollah Khamenei and effectively closed the Strait of Hormuz, triggering a classic safe-haven rotation into USD, gold, and Treasuries. The DXY surged ~1% to a five-week high near 98.5, dragging EM currencies lower — but the real’s 0.60% loss was contained relative to the magnitude of the shock, thanks to heavy exporters selling into the spike above 5.21.
Brent crude surges 6.7% to $77.74, a double-edged sword for BRL. The oil shock helps Petrobras revenues and Brazil’s terms of trade in the near term, but a sustained move toward $90+ would reignite domestic inflation fears and complicate Copom’s March easing signal. PPI coming in hot at +0.8% MoM in the US already suggests tariff pass-through is building, reducing room for Fed cuts.
Focus survey trims YE dollar to R$5.42 and Selic to 12% — but that was pre-strike. The March 2 Boletim Focus cut the 2026 Selic forecast from 12.13% to 12% and trimmed the dollar from R$5.45 to R$5.42 for a second straight week, with IPCA steady at 3.91%. However, these inputs were collected before the Iran escalation, and next week’s survey will test whether the geopolitical shock alters the easing consensus ahead of the March 17–18 Copom.

02Market Commentary
Monday’s session opened under the heaviest geopolitical cloud FX markets have faced since the early days of the Ukraine conflict. The coordinated US-Israeli military strikes on Iran over the weekend — killing Supreme Leader Khamenei and effectively shutting the Strait of Hormuz — triggered an immediate flight to the dollar, with the DXY vaulting ~1% to 98.42, erasing its year-to-date losses and printing a five-week high.
USD/BRL spiked to an intraday high of 5.2146 (+1.56%) in early São Paulo trading before exporters and institutional sellers stepped in aggressively above the 5.20 handle, compressing the move to a +0.60% close at 5.1651. The reversal from the highs was notable: the pair gave back nearly two-thirds of its intraday gains, suggesting the market views the Iran shock as a transient risk event rather than a structural BRL re-rating. Correparti Corretora’s Jefferson Rugik noted that the initial spike attracted heavy selling from exporters locking in favorable rates.
Beneath the geopolitical noise, the fundamental picture for the real remains constructive. The Boletim Focus released Monday morning — with data collected before the strikes — showed the market trimming its year-end dollar forecast to R$5.42 (from R$5.45) and the Selic to 12% (from 12.13%), both for the second consecutive week. IPCA expectations held at 3.91%, well within the BCB’s 1.5pp tolerance band around the 3% center. The BCB’s January Copom statement had explicitly signaled that easing could begin at the March 17–18 meeting if conditions confirmed the expected scenario.
The complication now is oil. Brent crude surged 6.7% to $77.74 — its highest in over eight months — with WTI jumping 8% above $72. If this proves to be a short-lived supply disruption, the real’s carry advantage (Selic at 15% vs. Fed funds at 3.50–3.75%, a 1,125 bps spread) should reassert itself quickly. But a sustained Brent above $85 would force a fundamental re-think of the inflation trajectory, particularly after the US PPI already surprised to the upside at +0.8% MoM, signaling tariff-driven cost pass-through that could delay Fed cuts and keep the DXY bid.
The 10-year UST yield tells the story of competing forces: it fell as low as 3.96% on Sunday (haven bid) before reversing to 4.04% on Monday as inflation expectations reasserted themselves. The VIX rose 8% to 21.44, elevated but well below crisis levels, suggesting markets are pricing a contained conflict rather than a multi-front regional war — for now.
03Technical Analysis
Daily (ICE, Mar 3 09:04 UTC)
The pair opened Tuesday at 5.1712, flat from the March 2 close area. The dominant trend remains bearish — price trades well below the Ichimoku cloud (base ~5.30–5.36), below the 200-SMA at 5.4052, and at the lower Bollinger Band (5.17). However, the MACD histogram has printed its first positive tick at 0.0026, with the MACD line at −0.0380 vs. signal at −0.0405, hinting at waning downside momentum. RSI sits at 41.31 (signal 37.35), recovering from oversold territory but still below the neutral 50 line.
Monday’s intraday reversal from 5.2146 back to 5.1651 carved a long upper wick on the daily candle — a classic rejection of the 5.20 resistance zone. The 5.17 area (Bollinger lower band, recent consolidation floor) is acting as immediate support, with the 52-week low at 5.1154 the next downside target if the geopolitical premium fades. On the upside, the Kijun-sen at ~5.27 and the cloud base at 5.30 represent significant resistance zones that would require a sustained risk-off environment to test.
| Support | Level | Resistance | Level |
|---|---|---|---|
| Bollinger Lower / Floor | 5.1712 | Kijun-sen | 5.2690 |
| Feb 28 Close | 5.1344 | Bollinger Mid / Cloud Base | 5.2982 |
| 52-Week Low | 5.1154 | Cloud Top | 5.3616 |
| Psychological | 5.1000 | 200-SMA | 5.4052 |
04Forward Look
Iran escalation path is the dominant variable this week.
If the conflict remains contained — no sustained closure of Hormuz beyond 48–72 hours, no direct strikes on GCC oil infrastructure — the geopolitical premium should fade quickly and the carry trade will pull USD/BRL back toward the 5.12–5.15 range. However, if Iran retaliates with sustained missile strikes on Gulf states (Qatar’s Ras Laffan LNG facility was already hit) and oil pushes above $85, the dollar will maintain its bid and USD/BRL could retest 5.25–5.30.
Copom March 17–18 meeting is now in the crosshairs.
Before the Iran strike, the market was pricing a 50bp cut to 14.50% with high confidence. The oil shock introduces a clear upside risk to inflation expectations — the BCB will need to weigh the direct impact of higher energy costs (Petrobras is monitoring crude before adjusting fuel prices) against the counter-cyclical logic of easing into a slowing economy (GDP forecast at 1.82%). The DI curve will price this tension in real time this week.
Data calendar and year-end consensus.
ISM Services (Wednesday), US jobless claims (Thursday), and payrolls (Friday) will determine whether the “no-landing” narrative persists. Domestically, Brazil’s February trade balance and PMI data will test the real’s fundamental underpinning. Year-end consensus: Focus survey R$5.42; Long Forecast R$5.06; EFG International sees real rate support even with cuts. The structural BRL bull case — 1,125 bps carry, declining fiscal premium, October election positioning — remains intact but now faces its first serious exogenous stress test of 2026.
Verdict
Monday’s 0.60% dollar gain was a geopolitical reflex, not a trend reversal — the intraday rejection from 5.2146 back to 5.16 tells you the market is still selling rallies, not buying dips in USD/BRL. The 1,125 bps carry advantage and improving Focus consensus continue to anchor the structural downtrend from 6.10, but the Iran conflict has introduced genuine two-way risk for the first time since the February consolidation.
The critical question is whether Brent stays above $80 long enough to contaminate the inflation outlook and force Copom to delay or dilute its March easing signal. If oil normalizes below $75 within the week, USD/BRL retests 5.12. If the Strait of Hormuz remains disrupted and Brent pushes toward $90, the pair revisits 5.25–5.30 and the March cut becomes a coin flip.
Bias: Neutral-to-Bearish USD/BRL on the daily, downgraded from Moderately Bearish pre-strike. The structural trend favors the real, but geopolitical risk demands tactical patience. Elevated Volatility expected through the week. Year-end consensus range: R$4.66–R$5.42.
