Rio Times — B3/Ibovespa Daily Report · Covering March 31 Session · Published April 1, 2026
01Session Summary
Today’s Ibovespa market report covers a session that delivered the sharpest single-day gain in weeks. The B3‘s benchmark index surged 2.71% on Tuesday, closing at 187,461.84 — its highest finish since early March — as Iran de-escalation hopes unleashed a powerful risk-on rally across virtually every sector. Only four stocks in the entire Ibovespa ended in the red. This is part of The Rio Times’ daily coverage of Brazilian equities and Latin American financial markets.
The catalyst was unmistakable: reports that Iranian President Masoud Pezeshkian is open to ending the war with guarantees, combined with President Trump telling aides he was willing to end military operations in Iran, triggered a global relief rally. The Strait of Hormuz remains largely blocked — its effective closure for weeks has fueled a sharp spike in global oil and gas prices — but the prospect of a resolution sent Brent crude tumbling and bond yields falling, creating a powerful tailwind for rate-sensitive sectors.
The breadth was extraordinary — the mirror image of recent selloffs. Banks, industrials, utilities, and miners all rallied in unison. The only meaningful losers were oil-linked names: Petrobras and PRIO fell as the de-escalation narrative implied a lower oil-price trajectory ahead. Despite the strong session, March still ended negative for the Ibovespa, capping a volatile month dominated by the Iran war.
1
Iran peace hopes unleashed global risk-on rally. Reports that Tehran is open to negotiations under specific guarantees, combined with Trump signaling willingness to withdraw U.S. forces within two to three weeks, sent equities soaring worldwide. The S&P 500 gained 2.91%, the Dow climbed 2.49%, and the Nasdaq surged 3.83% — each posting their best day since May. Brent crude pulled back sharply as the geopolitical risk premium began unwinding.

Banks and Vale led the Ibovespa while Petrobras was the notable laggard. Itaú surged 4.21%, Bradesco gained near 3.3%, and Banco do Brasil rose 2.68% as falling bond yields boosted the rate-sensitive financial sector. Vale jumped 3.75% after unveiling plans for Vale Base Metals to contribute 30–35% of consolidated EBITDA by 2035. Natura soared 12.99% on board renewal and Advent’s entry. Petrobras, however, dropped — PETR4 fell 2.01% and PRIO cratered 8.17% — as lower oil prospects undercut the energy trade.

Domestic data painted a mixed picture behind the rally. Brazil’s CAGED report showed 255,321 net formal jobs created in February, below the 269,000 consensus but the strongest reading for any month since February 2025. Gross public debt rose to 79.2% of GDP in February from 78.7% in January. The Focus survey revised 2026 IPCA inflation expectations upward to 4.31%, while Itaú BBA, Santander, and XP all lifted their inflation forecasts to 4.5%. The oil shock continues to push cost-of-living pressures through fuel, freight, and food chains.

03Technical Analysis
The Ibovespa gapped up from Monday’s close of 182,515 and never looked back, printing a convincing bullish engulfing candle on the daily chart. The close at 187,462 sits above the Ichimoku cloud’s Senkou Span A at 181,273 and reclaims the Tenkan-sen (182,769) and Kijun-sen (182,291) — both of which had acted as resistance during the late-March correction. Price is now testing the upper Bollinger Band at 186,877, suggesting a possible short-term overextension, though the band itself is expanding, indicating rising volatility rather than a ceiling.
The MACD histogram is marginally positive at 418.81, with the signal line at 391.09, confirming a fresh bullish crossover. The RSI has recovered to 58.64 from oversold territory reached earlier in March, with the slow line at 48.42 still playing catch-up — a configuration that typically supports continued upside before overbought conditions emerge.
The USD/BRL daily chart tells the complementary story. The pair dropped 1.65% to 5.1781, falling through the Kijun-sen at 5.2325 and testing the 200-day SMA cluster around 5.23. The pair sits within a descending Ichimoku cloud, confirming the medium-term bearish dollar/bullish real trend. RSI at 50.85 is neutral, while MACD is near zero, suggesting the real’s direction will depend heavily on whether Iran peace talks progress or stall in coming days.

04Forward Look
Trump has set April 6 as the deadline for Iran to reopen the Strait of Hormuz. Defense Secretary Hegseth stated the U.S. plans to leave Iran in “two to three weeks.” However, Iran’s Foreign Minister Araghchi pushed back, stating Tehran seeks a full end to the war, not just a ceasefire — including guarantees and compensation. The gap between rhetoric and reality remains wide. Any collapse in talks could instantly reverse Tuesday’s rally.
ISM Manufacturing PMI and ADP private payrolls release Wednesday (April 1). The March nonfarm payrolls report hits Friday (April 3) — Good Friday — when U.S. cash markets are closed. These reports will determine whether the oil shock has begun compressing growth and hiring, or remains isolated to prices. ISM Prices Paid above 73 would signal the worst input cost environment since 2022.
Petrobras will raise jet fuel (QAV) prices by approximately 55% starting April 1, compounding pressure on airlines already reeling from elevated crude. Meanwhile, André de Paula (PSD-PE) takes over the Agriculture Ministry from Carlos Fávaro, who leaves to run for Senate in Mato Grosso. The transition comes at a sensitive time for agribusiness policy amid soaring fertilizer and fuel costs.
The Focus survey revised 2026 IPCA to 4.31% (from 4.17%), and major banks have now lifted their forecasts to 4.5% — approaching the upper bound of the target range. Itaú BBA raised its terminal Selic forecast to 13.00% (from 12.25%), reflecting the persistent inflationary impulse from the oil shock. The BCB’s ability to continue its cautious easing cycle now hinges on whether peace materializes or the Hormuz disruption persists.
05Verdict
Tuesday’s session was the Ibovespa’s strongest performance in weeks, but it was driven almost entirely by a single variable: the probability that the Iran war ends soon. The breadth — only four losers across the entire index — tells you this was a binary geopolitical trade, not a fundamentals-driven advance. When one headline can move the index 2.71% in either direction, position sizing matters more than conviction.
The domestic backdrop is deteriorating quietly behind the geopolitical noise. Job creation missed consensus, gross debt keeps climbing, and inflation expectations are drifting toward the ceiling of the target range. The BCB is boxed in: the oil shock demands caution on rates, but the economy needs relief from 14.75% Selic. Petrobras’ 55% jet fuel hike starting tomorrow is a tangible reminder that oil-shock inflation is not just a forecast — it is arriving in real prices.
The technical setup favors cautious optimism. The Ibovespa reclaimed both Ichimoku equilibrium lines and sits above the cloud, with MACD freshly bullish. But the close is pressing the upper Bollinger Band, and the rally needs follow-through to avoid becoming a one-day wonder. The April 6 Hormuz deadline is the make-or-break catalyst. A deal opens the path back toward February’s record highs above 192,000. A breakdown in talks could send the index tumbling back to the 175,000–178,000 support zone faster than most portfolios can adjust.
Bias: Cautiously bullish — headline-dependent. Trade the structure, not the hope.
