B3 / Ibovespa Daily Report · March 31, 2026 · Covering March 30 Session
02 Market Commentary
Today’s Ibovespa market report covers a session that demonstrated Brazil’s now-structural oil advantage. The index rose 0.53% to 182,514 — snapping a three-day losing streak — while US equities struggled to hold pre-market gains. Vale and Petrobras led the recovery as Brent surged above $107, the highest level since mid-March. WTI settled above $100 for the first time since the war began. Brazil’s commodity-heavy index continues to outperform Wall Street in the war regime: when oil rises, Petrobras carries the Ibovespa while the Nasdaq sinks. This is part of The Rio Times’ daily coverage of B3 and Latin American financial markets.
The FT’s Kharg Island report was the session’s most consequential headline. The suggestion that Trump would prefer to seize Iran’s primary oil export terminal — rather than negotiate — represents a potential escalation from sanctions to occupation. The market’s reaction was telling: oil surged but equities did not crash, suggesting investors are beginning to differentiate between escalation that benefits commodity exporters (Petrobras, Vale) and escalation that hammers rate-sensitive names (banks, retailers). This rotation has been the Ibovespa’s defining feature for five weeks.
The week ahead is shortened by Good Friday (April 3) and loaded with risk. Fed Chair Powell’s Harvard appearance on Monday offered no new policy signals but reinforced the “data-dependent” stance. The VIX above 30 — its highest in a year — means options markets are pricing extreme tail risk into the Easter weekend. The Dow, Nasdaq, and Russell 2000 are all in correction; the S&P 500 is the only holdout, hovering near the −10% threshold.
03 Technical Analysis
The daily chart shows a constructive green candle (O 181,561 / H 184,414 / L 181,559 / C 182,514), opening at the low and rallying nearly 2,900 points to the session high before fading. The MACD histogram at 78.83 (signal: −53.60, MACD: −132.43) is positive and growing — the strongest reading since the recovery began. RSI at 51.06 (fast) has reclaimed the 50 line, while the slow line at 47.91 is approaching from below. This is the most technically constructive configuration since mid-March.
Price closed above the Kijun-sen at 180,720 and the Bollinger mid-band at 181,333, sitting between the Senkou Span cluster at 182,276–182,316. The Tenkan-sen at 183,831 is the next resistance target. The lower Bollinger at 177,299 and the prior week’s low at 176,677 provide downside support. The 200-day SMA at 155,131 confirms the secular uptrend.

04 Forward Look
US markets close Friday for Good Friday. March NFP releases that day into a closed market. Thursday becomes the de facto weekly close — expect defensive positioning into a 3-day weekend with an unresolved war, VIX above 30, and the April 6 Iran deadline three days later.
The Kharg Island report changes the calculus. If the US is considering a ground seizure of Iran’s oil export hub, the April 6 deadline becomes more dangerous than the original March 28 one. Petrobras benefits from any further oil surge but the broader index would sell off on escalation fears.
Iran deadline (Apr 6), February PCE (Apr 9), and Warsh hearing (possibly Apr 13) compress the highest-stakes catalysts of the war into a single week. The Ibovespa’s positioning will depend on whether Petrobras’ oil leverage can offset the broader risk-off that each of these events could trigger.
05 Verdict
Key Facts
— Monday’s bounce confirmed the Ibovespa’s now-structural pattern: oil up → Petrobras up → index up, regardless of what Wall Street does. The MACD histogram is positive and growing, RSI has reclaimed 50, and the three-day losing streak is broken. But the session also showed the limits of the pattern — the index touched 184,414 before fading nearly 2,000 points, reflecting the market’s inability to sustain gains when every rally faces an escalation headline. The FT’s Kharg Island report is the most significant escalation signal in weeks, suggesting the conflict may be entering a new phase where oil infrastructure becomes a military objective rather than a diplomatic bargaining chip.
— Bias: NEUTRAL — technically improving but macro headwinds intensifying. A close above 183,831 (Tenkan-sen) would upgrade to Cautiously Bullish. A close below 181,333 on Kharg escalation would downgrade to Bearish. The holiday-shortened week with VIX above 30 means positioning will be defensive regardless of direction.
