Today’s Focus
Monday’s tape was a substitution of risks, not a cleansing of them. Trump confirmed he had called off Tuesday’s planned strike on Iran at the request of Qatar, Saudi Arabia and the UAE, and Brent fell 1.42% to $107.71, then kept sliding into extended trade.
But the 10-year Treasury yield climbed above 4.6% — a 52-week high — on fears that incoming Fed chair Kevin Warsh will, in Ed Yardeni’s words, “tolerate inflation rather than hike.” The bond market took back with one hand what oil gave with the other.
For Brazil that combination is unhelpful. The Ibovespa closed almost flat at 176,975 but printed a fresh cycle low at 175,811 — the third consecutive session with a new intraday low. The BRL closed below R$5.00 for the first time since late April, but the rate-sensitive side of the index kept bleeding.
What matters today. Fed Waller speaks at 08:00 ET — the last major FOMC voice before Warsh is sworn in. Canada CPI lands at 08:30, with consensus at +3.1% YoY versus +2.4% prior. US Pending Home Sales follows at 10:00. After the close tomorrow, Nvidia reports — the global event of the week.
01 The Trump–Iran Pivot Took Oil Risk Off — the 10Y Replaced It With Rate Risk
The oil bid that defined the previous week collapsed when Trump posted that the leaders of Qatar, Saudi Arabia, and the UAE had told him “serious negotiations are underway with Iran that will result in a deal acceptable to the U.S.” — and that he had instructed the Pentagon to stand down from a Tuesday strike. Brent fell from intraday highs above $111 to settle at $107.71, then continued lower in extended trading toward $102 on reports the U.S. floated a temporary sanctions waiver, per Trading Economics.
The de-escalation flowed directly to the BRL, which broke back below R$5.00 to close at R$4.9901 for the first time since late April — the war-premium FX trade unwinding faster than the equity panic. But the 10-year Treasury yield climbed above 4.6% to its highest level since February 2025, and the 30-year held around 5.13%, the highest since 2007. Morgan Stanley’s Michael Wilson flagged 4.5% as the level at which yields become “a noticeable headwind for equity multiples,” and the Nasdaq’s loss against a positive Dow showed the rotation underway. Kevin Warsh will be sworn in as Fed chair this week, and Yardeni warned clients Sunday that “the bond market fears that he will tolerate inflation rather than hike the federal funds rate.”
The Trump–Iran pivot is fragile: Axios reports Iran’s counter-proposal is “not a meaningful improvement,” meaning Brent could rebound quickly. The 10Y spike, however, is structural — driven by Warsh transition risk, not a one-day data point. Bias: the rate-risk side of the substitution is more durable than the oil-relief side, and the Ibovespa’s commodity weight loses the war premium without picking up the rate-cut bid.
02 Brazil Macro: IBC-Br Shock Changes the Copom Math
The IBC-Br for March came in at −0.7% MoM, sharply below the −0.2% Reuters consensus, with all sectors declining and services down 0.8%, per Reuters citing BCB data. Q1 still grew 1.3% QoQ on strong January–February momentum, but the March print is the first concrete evidence of the deceleration thesis the Copom has been signaling. Suno Research’s Rafael Perez told Reuters the read reflects “ongoing effects of restrictive monetary policy on economic activity.”
Services down 0.8% is the variable the Copom watches most carefully for de-anchoring of inflation expectations versus demand cooling, and a contraction that size in a single month is unambiguously demand-cooling. Combined with Brent’s retreat to $107 and the BRL back below R$5.00, the committee now has three constructive inputs versus the May 5 ata’s “net dovish” framing: cooling activity, easing oil pressure, stronger currency. The hawkish inputs — Fed cuts priced out for 2026, the 10Y at 4.6%, Focus IPCA at 5.02% — remain in place, but the dilemma has eased materially. Genial’s 13.25% terminal stays the outlier; consensus is shifting back toward 13.50–13.75%.
03 Technicals — The Ibovespa Prints a New Cycle Low at 175,811
Monday opened at 177,281 and barely traded above the bell. The high came in just below 177,330, the low at 175,811, and the index closed at 176,976. The “Open ≈ High” pattern has now repeated four times in this correction, and each session has set a fresh intraday low.
That 175,811 print matters. It’s the deepest level of the entire 2026 correction, sitting roughly 11.5% below the 198,658 all-time high. The market is testing whether the cycle has another leg down.
Momentum confirms the pressure. The MACD histogram fell to a new cycle extreme — nearly 230 points wider than Friday’s reading — and the RSI signal line dropped firmly inside oversold territory for the first time in the correction.
Resistance overhead. The first ceiling is yesterday’s close at 176,976, then Friday’s close at 177,284. Above that, the chart opens up to 180,777, 182,046 and 185,809 — the last being the Kijun, which has been falling fast.
Support below. The first line of defense is yesterday’s intraday low at 175,811. Below that, 174,186 is the next chart level, and 163,396 — the 200-day moving average — sits well below as the structural floor.

Key Events — Today
05 Latin America — The Iran Pivot Splits the Region
Monday split LatAm decisively for the first time in two weeks. Argentina’s MERVAL surged 4.00% — the largest single-session gain since early April — pulling the index back above its Kijun, with YPF rocketing 8.23% on shale-export deal speculation. Mexico’s IPC added 0.63% with breadth turning positive. Chile’s IPSA rose 0.45% on a constructive engulfing pattern.
Brazil and Colombia were the laggards. The Ibovespa printed a new intraday low at 175,811 even though it closed almost flat, and COLCAP fell another 0.98% — though Ecopetrol was the bright spot of the regional tape at +5.50% on the oil-pivot trade. The split tracks the Iran de-escalation logic: oil-importing economies benefit from Brent’s retreat; the Ibovespa’s commodity weight loses the war premium without picking up the rate-cut bid.
06 Bottom Line
Positioning Call
Monday rotated the risk profile rather than reduced it. Trump’s pivot to “serious negotiations” with Iran took war premium out of Brent. The BRL closed back below R$5.00. But the 10Y broke to a 52-week high above 4.6%, and the tech complex sold off on memory-chip fears ahead of Wednesday’s Nvidia print. The Ibovespa printed a new intraday low at 175,811 — the deepest print of the entire 2026 correction.
Tuesday’s pivots are Canada CPI at 08:30 ET — a number in line with the +3.1% YoY consensus would confirm the global inflation acceleration thesis — and Fed Waller at 08:00, the last major FOMC voice before Warsh is sworn in. The IBC-Br at −0.7% is constructive for the Copom: services down 0.8% is exactly the cooling-demand evidence needed to justify continued easing into June.
Bias: Cautiously constructive on a 24-hour view, structurally cautious on a one-week view. The Trump-Iran pivot, BRL below R$5.00, IBC-Br softness, and IPSA/MERVAL/IPC breadth turning positive are the first constructive cluster since early May. But 175,811 must hold today — a fourth consecutive intraday low would reopen 174,186 as the next chart level and put 163,396 (the 200-day SMA) in play. Watch Waller at 08:00, Canada CPI at 08:30, and Brent through the New York hours. Wednesday is Nvidia.
Frequently Asked Questions
Why did Brent oil fall on Monday, May 18?
Brent crude fell 1.42% to $107.71 on Monday and continued lower in extended trading after President Trump confirmed he had called off a planned U.S. military strike on Iran scheduled for Tuesday, per CNBC and Trading Economics. Trump posted that the leaders of Qatar, Saudi Arabia, and the UAE told him “serious negotiations are underway with Iran that will result in a deal acceptable to the U.S.” However, a senior U.S. official told Axios that Iran’s latest counter-proposal is “not a meaningful improvement,” meaning a deal remains uncertain and oil could rebound quickly.
What did Brazil’s IBC-Br for March show?
Brazil’s IBC-Br economic activity index fell 0.7% in March on a seasonally adjusted basis — sharply below the −0.2% Reuters poll consensus, per Reuters citing BCB data. All sectors declined, with services (the main driver of Brazil’s economy) falling 0.8% from February. The Q1 reading still grew 1.3% from the previous quarter on strong January–February momentum, and the index rose 3.1% from a year earlier on a non-seasonally adjusted basis. Suno Research’s Rafael Perez told Reuters the print reflects “ongoing effects of restrictive monetary policy on economic activity.”
Why did the 10-year Treasury yield rise to a 52-week high?
The 10-year Treasury yield climbed above 4.6% on Monday, the highest level since February 2025, per TheStreet. Ed Yardeni told clients that “the bond market fears that he [incoming Fed chair Kevin Warsh] will tolerate inflation rather than hike the federal funds rate.” Warsh is scheduled to be sworn in this week as Powell’s successor. Morgan Stanley‘s Michael Wilson flagged 4.5% as the level at which yields become “a noticeable headwind for equity multiples,” helping explain why tech stocks led Monday’s losses with the Nasdaq down 0.51% versus the Dow up 0.32%.
When does Nvidia report and why does it matter for Brazil?
Nvidia reports Q1 FY2027 earnings on Wednesday, May 20, after the U.S. market close. The print is the most anticipated corporate event of May because Nvidia‘s market cap reached a record $5.7 trillion on May 14 before pulling back, and the AI trade has been the primary driver of the S&P 500’s record highs above 7,500. For Brazil, the relevance is indirect but powerful: a strong Nvidia print would likely reignite global tech risk appetite and help offset the 10-year yield above 4.6%, supporting EM equity flows. A miss would confirm the tech profit-taking thesis and add pressure to the Ibovespa already at three-week lows.
