The Big Three
The Ibovespa crashed 1.65% to 192,888.96 (−3,243.10 points) on Wednesday — the steepest single-day decline since the war began — as Petrobras went ex-dividend and the market repriced two days of accumulated Tiradentes risk in a single session. The open was the high (196,132 = O = H), meaning sellers dominated from the first tick. The index plunged to 192,687 intraday — its lowest since April 9 — before a marginal late bounce. The Petrobras ex-JCP adjustment (R$0.65 per share, first tranche R$0.32 paid May 20) accounts for roughly 60–70% of the move mechanically, but the additional selling in banks and Vale confirms this was more than a dividend haircut: the market used the reopening to de-risk after 48 hours of ceasefire uncertainty.
The dollar held flat at R$4.9669 (+0.05%) — confirming that the equity crash was mechanical and rotational, not systemic. If this were a capital-flight event, the dollar would have spiked above R$5.00. Instead, it barely moved. The RSI at 32.70 (signal: 31.64) remains deeply oversold — both lines now approaching the 30 threshold. The MACD histogram at −0.0653 has narrowed slightly, hinting at deceleration in the dollar’s downtrend. The real at R$4.97 is still the strongest EM currency of 2026. The equity-FX divergence that defined last week is even louder today: the Ibovespa dropped 1.65% and the dollar went nowhere. No foreign outflow. No carry-trade unwind. No institutional panic.
The MACD histogram collapsed from 554 to 136 — the weakest bullish reading since the ceasefire rally began — while the index dropped below the cloud top (Senkou A) at ~193,807 for the first time since April 10. The RSI at 65.35 is misleading — it hasn’t caught up to the day’s damage because of the lag from the Tiradentes gap. The real technical read: the Ibovespa has now given back 5,768 points (2.90%) from the ATH of 198,657, breaking below the 195,540 Kijun support and the 193,807 cloud top in a single session. The next support is the 191,489 level visible on the chart (Senkou B / lower cloud boundary). The Copom meeting on April 28–29 — now 5 days away — is the only catalyst that can arrest the correction.

02 Equities — Ex-Dividend Drop Meets Post-Holiday De-Risking
Today’s Ibovespa today report covers the session that answered a question the market had been postponing: what happens when the ex-dividend mechanical adjustment, 48 hours of Tiradentes gap risk, and a ceasefire extension that hasn’t resolved the oil question all land on the same day? The answer: −1.65%, sellers from the first tick, and the steepest single-session decline since the war began. This is The Rio Times’ continuing daily coverage of Brazil’s stock market and the broader Latin American financial markets.
The Petrobras ex-JCP was the primary mechanical driver. The R$0.65 per share adjustment (first tranche R$0.32, paid May 20) removes approximately 1,700–2,000 points from the Ibovespa given Petrobras’s ~13% index weight. But the total drop was 3,243 points — meaning roughly 1,200–1,500 points of selling came from elsewhere: banks, Vale, and broad de-risking by institutions that had been locked out of the market during Tiradentes. The open = high pattern (196,132 for both) is the most bearish intraday structure possible — there was zero buying interest above Friday’s close. The market priced the ceasefire extension as neutral (not bullish), the ex-dividend as expected, and the Tiradentes gap as a reason to lighten.
The damage was broad. Banks were under pressure — the Finance News headline read “Ibovespa em queda sob pressão das ações dos bancões e da Vale.” The index broke below both the 195,540 Kijun support and the 193,807 cloud top in a single session, landing at 192,889 — inside the Ichimoku cloud for the first time since April 10. The Petrobras dividend story is now behind the market (shares trade ex from today). The question is whether the index stabilizes at 192,889 or continues toward the lower cloud boundary at 191,489.
03 Dollar — R$4.97 Holds, No Panic
From the chart: O:4.9645, H:4.9669, L:4.9669, C:4.9669 (+0.0024, +0.05%). The dollar’s non-reaction to a 1.65% equity crash is the day’s most important data point. In any normal correction, a 3,243-point index drop would push the dollar above R$5.00. Instead, it went from R$4.9645 to R$4.9669 — effectively zero. RSI at 32.70 (signal: 31.64) — both approaching 30 (formal oversold). MACD histogram at −0.0653, narrowing slightly. The structural forces (14.75% Selic, R$67.4B foreign inflows, DXY weak, ceasefire extended) continue to overwhelm any equity-driven selling pressure. The R$4.8750 chart floor is the medium-term target. Resistance: R$4.9789 → R$4.9958 → R$5.0673.
04 Technical Analysis — Ibovespa Daily
From the chart: O:196,132.06, H:196,132.06, L:192,687.29, C:192,888.96 (−3,243.10, −1.65%). The candle is a tall red body with no upper wick (open = high) — the most bearish structure in the entire April series. RSI at 65.35 (signal: 56.16) has the main line still elevated but the signal diverging sharply — expect the main RSI to drop toward 55–58 on Thursday’s candle. MACD at 3,500.55 (signal: 3,364.67, histogram: 135.87) — the histogram has collapsed from the April 14 peak of 1,525 through 797 → 554 → 136 in four sessions. A zero cross is now possible within 2–3 sessions if the selling continues.
The 200-day SMA at 159,280 sits 21.1% below — the uptrend is unchallenged. But the near-term structure has deteriorated: the index is now inside the Ichimoku cloud (between 193,807 Senkou A and 191,489 Senkou B), which signals a transition from bullish to neutral. Key levels: 195,780 (upper range, now resistance) → 192,889 (close) → 191,489 (Senkou B / lower cloud) → 190,782 → 187,197 (Kijun/Tenkan convergence) → 187,039 → 179,141. Upside requires a close above 195,780 to re-enter bullish territory. The Copom decision on April 28–29 (25bp cut to 14.50%) is the reset catalyst.

06 News in Focus
Petrobras Ex-Dividend: R$0.65 Per Share, First Tranche May 20
Wednesday was the data de corte for Petrobras‘ JCP (juros sobre capital próprio) of R$0.65 per share. The first tranche of R$0.32 per ON and PN share will be paid on May 20, 2026. Starting today (Thursday, April 23), shares trade ex-JCP. The mechanical ex-dividend adjustment — which removes the JCP value from the share price — accounted for the majority of the Ibovespa’s 3,243-point decline. The R$41.2 billion total 2025 distribution (approved at the AGM on April 16 with 84.56% support) is now fully in the market. The government and BNDES receive R$17.6 billion of the total. The Petrobras dividend story is now backward-looking — the forward question is earnings under $89 oil.
Ceasefire Extended But Market Prices It as Neutral
Trump’s Tuesday ceasefire extension — open-ended, “until Iran submits its proposal” — was supposed to be the positive catalyst for Wednesday’s reopening. Instead, the market treated it as already priced. The Ibovespa opened at the Monday close (196,132) and immediately sold off. The ceasefire is held together by Trump’s Truth Social posts rather than a signed agreement. Vance did not travel to Pakistan. Iran has not confirmed delegates. The Hormuz reopening from Friday was reversed by the IRGC. Oil at $89 is the “uncomfortable middle” that neither unlocks a dovish 50bp Copom cut nor supports Petrobras at pre-correction levels. The ceasefire extended — but the market wanted more.
Lula in Germany: Scholz Bilateral, Be8, and Biofuel Diplomacy
President Lula continued his European tour with a bilateral meeting with German Chancellor Scholz. The centrepiece was Be8’s biofuel technology presentation — a synthetic fuel claiming 99% emissions reduction. Lula reiterated his criticism of the Iran war as “inconsequente” and called for multilateral diplomacy. For markets, Lula’s European tour has zero short-term price impact but reinforces Brazil’s positioning as a dual energy player: fossil (Petrobras) and transition (biofuel/ethanol). The trade-surplus story remains intact — Safras raised soy output to a record 178.1M tonnes, and Brazil’s trade surplus is up 151% YoY.
07 Looking Ahead
The ex-dividend adjustment is now behind the market. Thursday’s session (today) is the first “clean” day since April 14 — no holiday, no ex-dividend, no ceasefire deadline. The question: does the index stabilize at 192,889 (inside the cloud) or continue toward the lower boundary at 191,489? The MACD histogram at 136 is dangerously close to a zero cross — if it goes negative, the technical signal shifts from “bullish decaying” to “bearish.” The Copom on April 28–29 is the reset catalyst: a 25bp cut to 14.50% with dovish guidance would stabilize the market; a hold would extend the correction toward 190,782.
The earnings calendar begins: Gerdau Q1 on April 27, Vale Q1 on April 28. Both land before or during the Copom — giving the market fundamental data alongside the rate decision. The Petrobras dividend is now in the past. Oil at $89 is the variable. The dollar at R$4.97 is the anchor.
Key dates: Thursday April 23 — first clean session. April 27 — Gerdau Q1. April 28 — Vale Q1. April 28–29 — Copom (25bp expected). May 5 — Itaú/Bradesco Q1. May 11 — Petrobras Q1.
08 Verdict
The headline is ugly — 1.65%, 3,243 points, steepest drop of the war. But the signal beneath it is calmer. Roughly two-thirds of the decline is the Petrobras ex-dividend mechanical adjustment, which is non-recurring and expected. The remaining third is post-Tiradentes de-risking and bank selling, which is normal repositioning after a 48-hour information gap. The dollar at R$4.97 (flat) is the proof: if this were a thesis change, the currency would have moved. It didn’t. The Ibovespa is now inside the Ichimoku cloud at 192,889 — technically neutral, not bearish. The MACD histogram at 136 is the warning signal: a zero cross would shift the structure from “correction within a bull trend” to “potential trend change.”
Bias: Neutral — 191,489 is the floor, 193,807 is the ceiling, Copom is the reset. The index has corrected 2.90% from the ATH — roughly the Petrobras ex-dividend adjustment plus normal mean reversion after an 11-session rally. The structural drivers are intact: R$67.4B foreign inflows, R$4.97 dollar, 14.75% Selic carry, ceasefire extended, record soy harvest. The April MTD at +2.89% is still the best month of 2026. What broke was momentum (MACD from 1,525 to 136), not structure (200-day SMA 21% below, dollar flat, no outflows). Hold 191,489 through the week and the Copom resets everything. Break it and 190,782 / 187,197 come into play.
