Thursday, May 21, 2026 · Covering Wednesday May 20 session Summary

Ibovespa today reflects Wednesday's 1.77% rebound to 177,355.73, a sharp bounce off Tuesday's year-low oversold. The Senate move to curb Trump's Iran war powers pulled global yields and oil lower, easing the pressure on the election selloff. The real reclaimed sub-R$5 at R$4.9951.

The Big Three 1.
Ibovespa closed Wednesday at 177,355.73 (+1.77%, +3,076.87 pts), a reversal candle that opened at Tuesday's low (174,279) and closed near the high (178,199). The bounce came off RSI 28.76, the deepest oversold of 2026, after the Senate advanced a resolution to curb Trump's Iran war powers, easing the yield-and-oil pressure that compounded Tuesday's selloff. 2.
The real reclaimed sub-R$5, strengthening to R$4.9951 from Tuesday's R$5.0475 as the dollar bid eased on the de-escalation. The currency leads: when the war premium comes out of global yields, the carry trade reasserts and the real firms before equities, retracing the entire Tuesday slide - a cleaner signal than the equity bounce. 3.
RSI fast lifted to 37.19 from 28.76, slow 37.61 - off the floor but still soft. MACD histogram improved to −1,071.61 from −1,342.79. The election file is unresolved: Flávio Bolsonaro's Polymarket odds collapsed from 45% to 33% on an inflammatory interview, keeping the overhang live even as relief lifted the tape.

Source: B3, BCB, Polymarket, TradingView. Snapshot: May 21, 2026 06:14 UTC. 03 Why It Rebounded External Trigger: Iran de-escalation pulls yields lower

The catalyst was external. The US Senate advanced a resolution to curb Trump's Iran war powers, reducing the strike risk that had spiked Treasury yields to a 16-month high and lifted oil. As global yields retreated, the war premium came out of risk assets and the pressure on Tuesday's selloff lifted. Brazil, a net oil exporter with a 14.50% Selic carry, captured the relief through index and currency.

Local Overhang: The election file stays live

The rebound was a relief bounce, not a resolution. The Bolsonaro-Vorcaro file remains unresolved, and Flávio's Polymarket odds collapsed from 45% to 33% on an inflammatory interview. With the market-preferred candidate weakened, the October overhang persists - the bounce is external relief, not a change in the political risk.

§04 · Market Commentary

The bounce was textbook mean reversion off an extreme. RSI 28.76 was the deepest oversold of 2026, and the Iran de-escalation gave the tape a reason to snap back. The reversal candle and the real's clean retracement below R$5 are constructive near-term. The currency leads: when the war premium leaves global yields, the real firms first.

But the election overhang caps the upside. Flávio's collapse to 33% on Polymarket keeps the market-preferred-candidate risk live into October, and strategists warn election volatility can pin RSI through the campaign. The Kijun at 178,635 is the immediate resistance; reclaiming it confirms the bounce. The Selic at 14.50% anchors the carry case, with Copom June 17-18.

Ibovespa rebounded to 177,355.73 after opening at Tuesday's low and closing near the high - a bullish reversal candle off RSI 28.76. The Kijun at 178,635 is the immediate resistance, then 179,564 and the 183,007 cloud; the 200-DMA at 163,821 is the 7.6% floor.

Resistance: 178,635 (Kijun) → 179,564 → 183,007 (cloud) Support: 174,279 (Tuesday low) → 172,887 → 163,821 (200-DMA) Invalidation: A daily close back below 174,279 negates the reversal and reopens 172,887. 06 Forward Look This week · The Kijun A close above 178,635 confirms the reversal toward 179,564. A fade below the 174,279 Tuesday low negates the bounce. This week · Iran and yields A confirmed de-escalation extends the yield-and-oil relief. A breakdown re-spikes both and pressures the real above R$5. Ongoing · Election file Flávio at 33% on Polymarket reshapes the right-wing field. Vorcaro revelations or a polling recovery are the dominant volatility source into October. June 17-18 · Copom Selic at 14.50%. A sustained sub-R$5 real and easing oil revive the cut-path debate; the election overhang argues for a hold. 07 Questions & Answers Why did the Ibovespa rebound 1.8%? External relief and mean reversion. The US Senate advanced a resolution to curb Trump's Iran war powers, pulling Treasury yields off a 16-month high and easing oil. That removed the external pressure on Tuesday's selloff, and the index snapped back off RSI 28.76, the deepest oversold of 2026. Why did the real reclaim sub-R$5? The carry trade reasserting. As the war premium left global yields, the dollar bid eased and the real firmed to R$4.9951, retracing the entire slide. The currency leads: foreign positioning rebuilds the real before equities when Brazil risk eases. The net-oil-exporter profile and 14.50% Selic carry amplify the move when oil and yields fall together. Is the election risk over? No. The Bolsonaro-Vorcaro file is unresolved, and Flávio Bolsonaro's Polymarket odds collapsed from 45% to 33% on an inflammatory interview. The market-preferred candidate is weakened, keeping the October overhang live. Strategists warn election volatility can keep RSI pinned through the campaign. Verdict

Wednesday's 1.77% rebound to 177,355.73 was textbook mean reversion off RSI 28.76, the year's deepest oversold, as the Senate move to curb Trump's Iran war powers pulled yields and oil lower. The reversal candle and the real's retracement to sub-R$5 are constructive near-term. But the election overhang caps it: Flávio's collapse to 33% on Polymarket keeps the October risk live. The Kijun at 178,635 is the gate. The Selic at 14.50% anchors the carry case into the June 17-18 Copom.
