USD/BRL Daily Report · March 4, 2026 · Covering March 3 Session
The Big Three
Dollar spikes 1.92% to R$5.2652 in classic flight-to-quality as Iran conflict deepens. The real gave back nearly all of its February gains in a single session. At its intraday peak, the dollar hit R$5.3441 (+3.45%), the highest level since early January, before exporters sold into the strength. The DXY climbed 0.70% to 99.07 as global investors piled into the greenback.
Hormuz closure and oil surge rewrite the Copom playbook — 50 bps cut now off the table. Brent crude surged to $82.14 (+5.8%), its highest since July 2024, after the IRGC formally declared the Strait of Hormuz closed. XP estimates each $10/bbl oil rise adds ~40 bps to IPCA in 2026, and the DI curve repriced sharply, collapsing the consensus from a 50 bps to 25 bps cut at the March 17–18 Copom. The inflationary pass-through from oil to the real economy represents the biggest threat to BRL since the December 2025 “Flávio Day” crisis.
Fed speakers turn cautious — Kashkari and Williams flag war-driven inflation uncertainty. Minneapolis Fed President Neel Kashkari said his confidence in the rate outlook eroded in days, shifting from expecting a cut to needing to “see how the data react to the war.” New York Fed’s John Williams called it “very early” to assess inflation impact but warned that past oil price moves of this magnitude have historically altered monetary conditions.

02 Market Commentary
The real’s worst session of 2026 was a study in cascading risk premia. Monday’s resilience — when USD/BRL rose only 0.62% to R$5.1651 despite the outbreak of war — gave way Tuesday to the full recognition that Hormuz is not a symbolic escalation but a material supply disruption. The dollar hit R$5.3441 intraday, a level not seen since early January, before exporters and BCB signaling brought it back to R$5.2652.
Bruno Shahini of Nomad described the session as a textbook flight-to-quality: the oil surge, VIX spike, and bond selloff combined to drive capital into the dollar and out of EM currencies. The BRL was not the worst performer among Latin American peers — the Colombian peso and Mexican peso suffered comparable or worse losses — but the speed of the move erased weeks of gains from the foreign flow that had driven the real to May 2024 lows.
The domestic macro backdrop was mixed but secondary. Brazil’s Q4 2025 GDP came in at +0.1% QoQ, with full-year growth of 2.3% — the weakest since the pandemic contraction. XP’s Rodolfo Margato noted that without agribusiness and extractive industries, 2025 growth would have been just 1.3%. January’s Caged report showed 112,334 formal jobs created (vs. 92,000 expected), but the deceleration in hiring pace from 135,000 to 80,000 per month in H2 2025 signals the lagged impact of 15% rates.
The critical channel now is oil-to-inflation-to-rates. Brent at $82 changes the calculus for both the BCB and the Fed. The carry trade that powered BRL strength through January and February — 15% Selic vs. 3.50–3.75% Fed Funds = ~11.25% differential — only works if both sides of the equation move predictably. An oil shock that simultaneously delays Fed cuts and forces the BCB to cut less compresses the differential and removes the anchor for BRL appreciation.
03 Technical Analysis
Daily (1D):
Tuesday’s long bullish candle broke above both the Tenkan-sen and Kijun-sen, which had been converging near 5.2763. The close at 5.2652 sits just below this Ichimoku equilibrium zone, suggesting price is testing resistance rather than confirming a breakout. The Senkou Span A and B are both clustered near 5.2301, meaning the cloud is thin and vulnerable — a daily close above 5.30 would put the pair firmly above the cloud for the first time since early January.
The MACD histogram remains negative at −0.0352, with the MACD line at 0.0148 and signal at −0.0204. However, the MACD line is above zero and attempting to cross above the signal — a bullish crossover that would confirm the trend shift if validated. The RSI fast line surged to 58.03 from below 40, while the slow line sits at 39.92, creating a wide divergence that typically precedes further upside momentum. The 200-day SMA at 5.4037 remains the major resistance overhead — the pair has not traded sustainably above it since December’s spike.
| Level | Rate | Reference |
| R3 | 5.4037 | 200-day SMA |
| R2 | 5.3567 | Bollinger upper |
| R1 | 5.3441 | Mar 3 intraday high |
| S1 | 5.2763 | Tenkan-sen / Kijun-sen |
| S2 | 5.2301 | Senkou Span A/B (cloud) |
| S3 | 5.1999 | recent swing low |
| S4 | 5.1798 | Bollinger lower |
04 Forward Look
Iran Conflict Duration:
The single most important variable for USD/BRL. Trump warned the conflict could last more than four weeks. If Hormuz reopens quickly and Brent retreats below $75, the carry trade reasserts and BRL can retrace toward 5.12–5.16. If Brent stays above $85 for weeks, USD/BRL likely tests 5.40+ and the 200-SMA.
IPCA February (March 12) and Copom (March 17–18):
The February IPCA will be the first hard data on whether oil pass-through is materializing. If inflation prints hot, the BCB may signal a pause rather than a cut, which would support BRL through rate differential but hurt equities. A 25 bps cut with hawkish guidance is the current base case — any deviation in either direction moves the pair sharply.
Foreign Flows and Election Premium:
Foreign inflows into B3 surpassed all of 2025 by late February, and the real’s YTD strength of ~5.9% reflected that structural bid. The key question is whether this flow reverses under geopolitical stress or merely pauses. The October 4, 2026 general election continues to shape medium-term positioning, with Flávio Bolsonaro’s rising polls adding a political premium that has paradoxically supported risk appetite.
Verdict
Tuesday shattered the BRL bull narrative that had dominated 2026. The real‘s 1.92% loss — its worst daily move since the December 2025 crisis — arrived not from a domestic policy mistake but from an exogenous energy shock that rewrites the inflation-and-rates calculus on both sides of the Atlantic. The carry that powered BRL to May 2024 lows is now under threat from both compression (delayed Fed cuts) and erosion (shallower BCB easing).
Technically, USD/BRL is probing the Ichimoku equilibrium near 5.2763 — a zone that served as resistance through all of February. The RSI fast-slow divergence (58 vs. 40) and the incipient MACD bullish crossover both suggest the pair has more upside runway if the conflict persists. The 200-day SMA at 5.4037 is the key overhead target; the Bollinger lower band at 5.1798 is the floor if de-escalation materializes.
The structural case for BRL — 15% Selic, record foreign inflows, improving fiscal optics ahead of elections — remains intact but is now conditional on the war’s duration. A week-long conflict produces a tradeable BRL dip; a month-long conflict produces a regime change in the pair.
Bias: BEARISH BRL (BULLISH USD/BRL) — downgraded from Bullish BRL. The pair needs to close below 5.2301 (cloud support) to restore the pre-conflict downtrend. Above 5.30, the 200-SMA at 5.40 becomes the next target.
