03 Market Commentary

Wednesday’s session delivered the rebound the market needed after Tuesday’s geopolitical shock. The Ibovespa closed at 185,366 — up 1.24% and 2,261 points — with 73 of 85 index constituents ending in positive territory. The breadth of the recovery matters: this was not a rotation rally driven by one or two heavyweights but a broad-based repricing as investors decided Tuesday’s panic was overdone. Context, however, demands caution: the index recovered roughly one-third of the 6,200 points shed on March 3.

The catalyst was diplomatic, not fundamental. The New York Times reported that Iranian intelligence had reached out to the CIA — via an unidentified third country — to explore a possible end to the conflict now in its fifth day. Washington remains openly skeptical: officials quoted by the Times called the offer ambiguous and said neither Iran nor the Trump administration appeared genuinely ready for a resolution in the near term. Yet the mere possibility of an off-ramp proved sufficient to compress the geopolitical risk premium that had crushed markets. The dollar shed 0.89% against the real, landing at R$ 5.2182, and ADP’s February private-sector jobs print — above expectations — added a constructive data point ahead of Friday’s official payroll.

The domestic narrative was dominated by Banco Master. Federal Police arrested Daniel Vorcaro, the bank’s controlling shareholder, on the morning of March 4 in the third phase of Operation Compliance Zero. Investigators allege a four-pronged scheme: a financial nucleus structuring fraud against the banking system; a corruption nucleus targeting BCB supervisors; and two additional operational wings. The central bank confirmed that ex-Supervision Director Paulo Sérgio Neves de Souza and ex-Banking Supervision department head Belline Santana received improper payments and reported them to the Federal Police. B3 absorbed the scandal without spreading contagion to Itaú, BTG, or other major financial names — the market’s implicit verdict was that this is an idiosyncratic failure, not a sector-wide rot.

Globally, the split between developed and emerging markets sharpened. Europe and Wall Street rallied — the Stoxx 600 gained 1.37% after two days of heavy losses; the Nasdaq added 1.29%. Asia went the other direction: Japan’s Nikkei slid 3.61% and Hong Kong’s Hang Seng fell 2.01%, still digesting Tuesday’s shock and the absence of a definitive Hormuz resolution. The VIX pulled back from Tuesday’s close of 25.95 to 23.57 — a meaningful improvement, though still in elevated territory that warrants vigilance.

04 Technical Analysis

Daily (1D):

Wednesday’s candle was a constructive bullish close off the lows, but it stopped well short of recapturing Tuesday’s breakdown levels. The close at 185,366 sits above the 20-day moving average (~181,152) — the critical near-term line that held as support at the session lows — but below the 186,570 area that now represents the first meaningful resistance cluster. The intraday high of 186,306 tagged that zone before sellers reasserted, producing a slightly bearish upper wick and signaling that supply remains overhead.

The MACD histogram deepened to −1,233.83 (MACD line: 4,460.13; signal: 3,226.31), more negative than Tuesday’s −1,085.81 — the bearish divergence is widening, not yet reversing, and requires a confirmed histogram uptick before calling a momentum bottom. RSI recovered to 65.95 from the mid-50s area, suggesting momentum returned but did not re-enter overbought territory. Stochastic RSI at 53.06 is neutral, consistent with a market still finding its footing. The 200-day SMA at approximately 151,229 remains a distant anchor, confirming the secular uptrend is structurally unbroken even as the tactical picture stays unsettled.

05 Forward Look

U.S. Payroll — Friday, March 6:

The official February jobs report is the week’s dominant macro event. Wednesday’s ADP beat — private sector jobs above consensus — raises the bar. A strong payroll number would reinforce the Fed‘s wait-and-see posture and could reverse some of the real’s recovery and weigh on rate-sensitive B3 sectors. A soft reading reopens the early-cut narrative and would be risk-positive for emerging markets.

Iran and the Strait of Hormuz:

The diplomatic signal from Tehran needs concrete follow-through before markets can price in de-escalation with conviction. Washington’s skepticism is not performance — officials are assessing whether Iran or the Trump administration is genuinely prepared for an off-ramp. Any recurrence of provocative military action, or a formal U.S. rejection of the Iranian overture, would rapidly erase Wednesday’s gains. Brent holding at $82 remains a real inflation threat to BCB’s March 17–18 Copom decision.

Kevin Warsh Nomination — Senate Process:

Trump’s formal submission of Warsh’s name to the Senate triggers a confirmation timeline. Any statements Warsh makes during the process about his monetary policy views — or Senate resistance to the nomination — will move rate curves and EM FX. Powell’s mandate expires mid-May, limiting the runway for uncertainty.

Operation Compliance Zero — Banco Master Fallout:

New phases of the operation or additional revelations about the scope of BCB infiltration could amplify reputational and regulatory risk for the broader financial system. Markets treated Wednesday’s news as idiosyncratic; a widening of the probe to other institutions would change that calculus. The October 2026 elections add political sensitivity to any narrative of systemic regulatory failure.

Verdict

Wednesday’s bounce was necessary but insufficient. The Ibovespa needed to prove the 181,000–183,000 zone would hold as support, and it did — the session low of 183,110 matched the open almost precisely, suggesting buyers defended that level with intent. The 1.24% close and 73/85 positive breadth argue against a broken market. But recovering one-third of Tuesday’s losses while the Hormuz closure persists, the MACD histogram stays negative, and the VIX remains at 23.57 is not a green light — it is a yellow one.

The Banco Master scandal reinforced an uncomfortable truth about the pre-election domestic environment: governance risk is not priced out of Brazilian equities. The BCB’s confirmation of compromised supervisors, just weeks before a Copom decision made more difficult by an oil shock, adds institutional noise to an already complex macro backdrop. That said, the market’s refusal to punish the banking sector broadly is a constructive signal — discrimination between names is returning.

The structural case for B3 remains intact. The 200-day SMA at 151,229 is 18% below current price. Foreign inflows in 2026 have been substantial. Selic at 15%, even with repricing risk, remains in a cutting cycle. But the next 48 hours — Friday’s payroll and any developments on the Hormuz diplomatic track — will determine whether Wednesday’s rebound becomes the base of a new leg higher or merely a dead-cat bounce within a deeper geopolitical correction.

Bias: NEUTRAL — upgraded from Bearish. Support at 181,152–183,110 validated; resistance at 186,306–186,570 intact. A confirmed close above 186,570 turns bias Bullish; a break below 180,772 (Bollinger midline) reinstates the Bearish case.
