The Big Three
Dollar sheds 0.89% against the real as Iranian ceasefire signals compress geopolitical risk premium. The New York Times reported that Iranian intelligence reached out to the CIA via an unidentified third country to explore an end to the conflict. The move triggered broad dollar weakness globally — the DXY fell 0.30% to 98.758 — and the real led EM currency recoveries as risk appetite returned after Tuesday’s panic sell-off.
Kevin Warsh nomination and Beige Book shift the Fed narrative toward a dovish medium-term path. Trump sent Warsh’s Senate nomination to replace Powell — whose mandate expires mid-May — formally opening a transition expected to favor rate cuts. The Beige Book confirmed modest U.S. growth and stable employment, keeping the next cut priced for July 28–29. A more accommodative Fed trajectory is structurally negative for the dollar against EM currencies including the real.
Spain reverses course on U.S. military cooperation, removing one layer of geopolitical friction. White House press secretary Karoline Leavitt confirmed that Spain agreed to cooperate with U.S. armed forces — a day after Trump threatened trade sanctions over Madrid’s refusal to allow U.S. aircraft to use jointly operated Spanish bases for the Iran offensive. The de-escalation on the NATO-ally front reduced tail-risk premium in the dollar and supported broader risk sentiment.

02 Market Commentary
The real reclaimed ground on Wednesday in a session defined entirely by geopolitical diplomacy. The dollar fell 0.89% to R$ 5.2182, reversing nearly half of Tuesday’s 1.92% surge — when the Ibovespa and the real both capitulated to the shock of the Hormuz closure and the death of Iran’s Supreme Leader. The move tracked global currency markets broadly: the DXY retreated 0.30% to 98.758 as risk appetite returned across EM FX, European equities, and Wall Street in lockstep.
The catalyst was the New York Times report on Iranian intelligence reaching out to the CIA to explore a ceasefire. Iranian agents signaled openness through the espionage agency of an unidentified third country — a backchannel, not a direct approach. Washington officials quoted by the paper remained skeptical about the sincerity of both sides’ willingness to exit the conflict in the near term. That skepticism is the key qualifier: the real’s recovery was driven by hope, not resolution, and is therefore fragile to any hardening of positions over coming days.
A secondary geopolitical positive emerged from Spain. White House press secretary Karoline Leavitt confirmed that Madrid had agreed to cooperate with U.S. armed forces — reversing its earlier refusal to allow American aircraft to use jointly operated Spanish bases for the Iran offensive. Trump had threatened trade sanctions the prior day; Spain’s capitulation removed that headline risk and added another layer of diplomatic de-escalation supporting risk sentiment. The episode nonetheless underscores the fragility of alliance cohesion in the current conflict, a variable the dollar will continue to price.
On the monetary policy front, the Fed’s Beige Book reported modest U.S. growth, persistent price pressures, and stable employment — a neutral-to-hawkish backdrop that, in isolation, would favor the dollar. But Trump’s formal submission of Kevin Warsh’s nomination to the Senate to succeed Jerome Powell added a medium-term dovish narrative: Warsh is expected to favor the rate cuts Trump has repeatedly demanded, and his anticipated arrival by mid-May reshapes the forward rate path. The next cut is priced for July 28–29. A more accommodative Fed is structurally negative for the dollar, providing a tailwind for the real beyond the near-term geopolitical noise.
03 Technical Analysis
Daily (1D):
The daily chart shows USD/BRL in a well-defined medium-term downtrend, with the 200-day SMA (descending blue trendline, ~5.4013) acting as the dominant structural ceiling. Wednesday’s close at 5.2182 sits comfortably below the 200-day and is pressing toward a dense cluster of short-term moving averages in the 5.2301–5.2731 zone. The pair’s price action since late January has been a compression within that MA cluster, making the Hormuz spike to 5.2652 on Tuesday a temporary breakout that was immediately rejected and reversed — a bearish signal for the dollar.
The MACD histogram turned positive at 0.0132 (MACD line: −0.0194; signal: −0.0326), the first green bar after a prolonged negative sequence — a nascent bullish crossover for the real (bearish for the dollar). The RSI at 51.29 is neutral, confirming no overbought conditions for further real strength. The Stochastic RSI at 40.22 has room to rise before reaching overbought levels, supporting potential continuation of the dollar’s decline toward the 5.19–5.18 support zone visible in the right-panel labels. Downside targets for the dollar are the 5.1956 and 5.1809 MA levels; a recovery above 5.2731 (orange MA) would neutralize the near-term bearish bias.
| Level | USD/BRL | Reference |
| R3 | 5.4013 | 200-day SMA (descending) |
| R2 | 5.3512 | MA resistance band |
| R1 | 5.2731–5.2887 | Orange MA / MA cluster ceiling |
| Close | 5.2182 | Mar 4 close |
| S1 | 5.2301 | Short-term MA support cluster |
| S2 | 5.1956 | Lower MA band |
| S3 | 5.1809 | Structural floor / recent cycle low zone |
04 Forward Look
U.S. Payroll — Friday, March 6:
The February jobs report is the single most important near-term driver for USD/BRL. Wednesday’s ADP print came in above expectations, raising the risk of a strong official payroll. A robust number would reinforce the Fed‘s hold posture, push back cut expectations beyond July, and give the dollar renewed strength — threatening the real’s recovery. A soft reading would do the opposite, accelerating BRL appreciation toward the 5.18–5.19 zone.
Iran Diplomacy — Ceasefire or False Dawn?
The Iranian backchannel needs to produce concrete momentum — a formal contact, a named mediator, a pause in hostilities — before the dollar can price in a sustained de-escalation premium. Washington’s public skepticism is a ceiling on the real’s gains. Any military escalation or U.S. rejection of the Iranian overture would push USD/BRL sharply back above 5.27–5.35 within hours, as markets proved on Tuesday.
Copom March 17–18 and Selic Path:
Brent at $82 with the Hormuz still closed complicates the BCB’s decision calculus. The DI curve has already repriced the March cut from 50 bps to 25 bps. If oil prices remain elevated into the February IPCA release on March 12, the BCB may signal a shallower cutting cycle — which would support the real via the carry differential. Conversely, a hawkish hold would risk damaging Brazil’s fragile growth outlook and hurt risk sentiment for BRL.
Kevin Warsh Confirmation Timeline:
Any dovish signals from Warsh during Senate confirmation hearings would accelerate dollar weakness and support EM currencies including the real. Conversely, Senate resistance or a hawkish pivot by the nominee would remove the medium-term dovish Fed narrative that is currently supporting BRL. Powell’s mandate expires mid-May, limiting the window of uncertainty.
Verdict
Wednesday’s dollar retreat to R$ 5.2182 confirmed that Tuesday’s spike to 5.2652 was a fear-driven overshoot, not a structural break. The 200-day SMA at 5.4013 remains a ceiling that has not been seriously threatened, and the medium-term downtrend in USD/BRL — established since mid-2025 — is technically intact. The MACD histogram turning positive for the first time in weeks adds a fresh momentum signal aligned with BRL strength.
The asymmetry of risks is worth noting. On the upside for the dollar: a hot payroll, a failed Iranian ceasefire attempt, or oil breaching $90 could rapidly push USD/BRL back above 5.35 and put the 200-day SMA in play. On the downside: a soft payroll, a genuine diplomatic breakthrough, and a dovish Warsh confirmation could accelerate the real toward 5.18 and eventually test 5.10. The carry differential — Selic at 15% versus Fed at 3.50–3.75% — continues to provide structural support for BRL on dips.
The Banco Master episode added domestic governance noise but did not materially alter the FX calculus. Brazil’s institutional risk premium has been elevated since the Lula fiscal shock of December 2024; one more scandal, however significant, does not reset the equation while the external carry trade remains intact.
Bias: BRL POSITIVE (USD NEGATIVE) — downtrend resuming. Geopolitical fragility caps conviction. Key trigger: Friday payroll. Hold below 5.2731 maintains the bear dollar case; a close above 5.2887 invalidates near-term BRL strength.
