Ibovespa Hits All-Time High as Iran War Pause

01Session Data

02What Happened

Today’s Ibovespa market report covers the most important session of 2026. The B3’s benchmark index surged 2.09% to a new all-time closing high of 192,201.16 — breaking above the February record of 191,490 — as a U.S.-Iran ceasefire triggered the most powerful global risk-on rally since the war began on February 28. The index briefly topped 193,759 intraday before Petrobras’s sharp decline pulled it back from those levels.

The ceasefire, announced Tuesday night after Trump’s 8 PM deadline, was mediated by Pakistan under what sources describe as the “Islamabad Accord.” Iran’s Supreme National Security Council accepted a two-week pause in hostilities, and Iran’s Foreign Minister confirmed that the Strait of Hormuz will be reopened during the truce “in coordination with Iran’s Armed Forces and with due consideration to technical limitations.” The accord halts a six-week conflict that caused the largest energy supply disruption in modern history.

The rotation was textbook — exactly as this report forecast in multiple prior editions. Banks, which had been dragged down for weeks by oil-driven inflation fears and rising rate expectations, exploded higher: Bradesco surged 5.00%, Banco do Brasil gained 4.48%, Itaú rose 3.50%, and Santander added 2.11%. The logic is simple: lower oil → lower inflation → higher rate-cut probability → banks and rate-sensitive domestics rally. Petrobras, which had been the index’s anchor throughout the war, fell more than 4% as Brent crashed approximately 13% to near $96 — its sharpest single-day decline since the conflict began. The index still closed at a record because banks have a larger combined weight than Petrobras alone.

The real broke below R$ 5.10 for the first time since May 2024, closing at R$ 5.103 (−1.00%). The global dollar weakened as oil’s crash removed the inflation premium that had been supporting U.S. rate expectations. Wall Street had its strongest day since the war began: S&P 500 +2.65%, Dow +1,226 points (+2.62%), Nasdaq +3.4%. The Stoxx 600 surged 3.68%. Airlines globally soared 9–13% as fuel costs collapsed. Energy stocks were the sole sector in the red. Volume on the B3 hit R$ 42.5 billion — more than 20% above the daily average — confirming heavy institutional participation in the rotation.

However, the session ended with a cautionary note: late reports emerged of alleged Iranian violations of the ceasefire, reminding markets that this is a two-week pause, not a permanent peace. Iran explicitly stated the ceasefire “does not mean the end of the war.” The Ibovespa’s pullback from 193,759 to 192,201 in the final hours reflected this lingering uncertainty.

03Technical Snapshot

The Ibovespa closed at 192,201.16, printing a massive bullish engulfing candle that broke decisively above the February all-time high of 191,490. The index opened at 188,261 (essentially unchanged from the prior close), surged to 193,759, and settled at 192,201 — a 5,499-point intraday range. RSI at 65.75 (signal: 54.25) has surged into overbought-adjacent territory for the first time since February’s record run. The MACD histogram exploded to 1,912.12 (MACD: 961.94, signal: 950.18) — the strongest momentum reading of 2026.

Key levels: Resistance at 192,201 (new ATH close) → 193,759 (intraday ATH) → 195,000 (psychological) → 200,000 (round number target). Support at 191,565 (prior February ATH, now support) → 187,368 (SMA cluster) → 186,544 / 185,884 → 184,514 / 184,399 (Ichimoku levels) → 183,304 (20-day area) → 182,788 → 175,043 (lower Bollinger) → 156,647 (200-day SMA).

The dollar crashed to R$ 5.103 (−1.00%), breaking below the May 2024 support at R$ 5.10 for the first time. The MACD remains deeply negative (−0.0129 / −0.0155 / −0.0284), confirming accelerating bearish momentum for the dollar. RSI at 45.56 (signal: 37.98) is well below neutral, with room for further real appreciation. The ceasefire removes the key driver that had been supporting the dollar globally — oil-driven inflation and rate-hike expectations. Support for USD/BRL now at 5.08 (next psychological level) → 5.05. Resistance at 5.15–5.17 (broken support, now resistance) → 5.20 → 5.33 (upper Bollinger).

04Verdict

This was the session we had been building toward. For weeks, this report argued that the Ibovespa’s “dual engine” structure — oil names on one side, domestics on the other — meant the index could rally in either a war or peace scenario. Wednesday confirmed the thesis: banks and rate-sensitive stocks more than offset Petrobras’s 4% decline, propelling the index to its first all-time high since February.

The rotation is real but fragile. The ceasefire is two weeks, not permanent. Iran said it explicitly. If talks collapse and the war resumes, oil spikes back to $110+, banks give back all of Wednesday’s gains, and Petrobras rallies — reversing the rotation entirely. The market’s challenge now is to determine whether this is a temporary ceasefire trade or the beginning of a sustained shift in market leadership from energy to financials and domestics.

Bias: Bullish — but respect the 2-week clock. The technical breakout to new ATH is decisive (RSI 65, MACD exploding, massive volume). The macro tailwinds are powerful: lower oil → lower inflation → stronger real → rate-cut path reopens. The carry trade is now supercharged. But all of this is contingent on the ceasefire holding and converting to a permanent deal. Position for continuation, but size for the risk that it doesn’t. The Ibovespa at 192,201 prices in a lot of good news — the question is whether the next two weeks deliver enough good news to justify it.

05Forward Look

Thursday April 9 — IPCA and U.S. CPI. The two most important inflation prints of the month arrive on the same day. Brazil’s March IPCA will show how much of the oil shock reached consumers. A softer reading would reinforce the rate-cut narrative and could push the Ibovespa higher. U.S. CPI later in the day will determine whether the Fed can contemplate cuts — a soft print would be a global risk-on catalyst; a hot print would complicate the ceasefire rally. The combination of these two readings with the ceasefire backdrop makes Thursday the most macro-dense day of the year.

Ceasefire watch — 13 days remaining. Ship traffic through Hormuz is the key real-time indicator. If oil tankers begin transiting in volume, the oil decline extends and the peace premium builds. Any reports of ceasefire violations — like the late Wednesday rumors — would immediately reverse the trade. The next Copom on April 28–29 now has a radically different backdrop: if oil stays near $96 and the ceasefire holds, the BCB has cover to signal the start of rate cuts, which would be the most powerful catalyst for Brazilian domestics.

Positioning shift: The ceasefire inverts the playbook. Banks, homebuilders, retailers, and rate-sensitive names are now the leadership cohort. Petrobras and oil juniors become laggards unless the ceasefire collapses. The Ibovespa’s first May–August preview already removed four names (Cyrela, Localiza, IRB, Axia C) — the index is increasingly concentrated around blue chips that benefit from this exact rotation. The real below R$ 5.10 for the first time since May 2024 signals the carry trade has room to run, particularly if the ceasefire converts to a permanent deal.
