01 Oil crashes 5.7% as Trump says Iran deal in “final stages” and supertankers leave Hormuz

WTI plunged 5.66% to $98.26 and Brent fell 5.63% to $105.02 after President Trump told reporters the administration was in the “final stages” of negotiations with Iran. Three supertankers left the Strait of Hormuz with full cargoes, the first significant commercial transit since the blockade began.

The S&P 500 snapped its three-day losing streak, gaining 1.08% to 7,432.97. The Dow surged 645 points to 50,009, retaking 50,000 for the second time this month.

Treasury yields retreated from Monday’s 19-year highs, with the 10-year pulling back from 4.69% toward 4.55%. Goldman Sachs estimated that a permanent Hormuz reopening would push WTI toward $75 within 60 days. Vice President Vance told reporters the US remains “locked and loaded” if negotiations collapse.

02 UK CPI drops to 2.8% but PPI input surges to 7.7%, widening Europe’s consumer-producer split

UK headline CPI fell to 2.8% in April (consensus 3.0%, prior 3.3%), with core easing to 2.5% (consensus 2.6%). RPI dropped to 3.0% from 4.1%. This is the sharpest monthly deceleration in UK consumer inflation since mid-2024.

But the pipeline tells a different story. PPI input surged to 7.7% year-on-year (consensus 5.9%), driven by crude oil and industrial metals. PPI output accelerated to 4.0% (consensus 2.8%), meaning factories are passing energy costs through at nearly double the expected rate.

Eurozone CPI confirmed at 3.0% and core at 2.2%, both inline. German PPI eased to 1.2% MoM (below the 2.0% consensus), the first below-consensus German producer-price reading since the war began.

For Brazil, the UK’s consumer-producer split mirrors the BCB’s own dilemma. The BCB cut to 14.50% into a falling IPCA at 4.39% but a surging PPI at 2.37% month-on-month.

If the pipeline catches up in both countries, the next inflation readings will be higher — and the Selic at 14.50% has less margin for error than the BoE’s 3.75%.

03 Nvidia beats with $81 billion but $91 billion guidance divides the whisper crowd

Nvidia reported Q1 fiscal 2027 revenue of $81 billion, above consensus, and guided $91 billion for Q2, also above Street models. The company raised its quarterly dividend to $0.25. CEO Jensen Huang called demand for Blackwell and Hopper chips “unprecedented.”

Shares whipsawed in after-hours trading, initially dropping before recovering to trade roughly flat. Trading Economics noted the Q2 guidance “fell short of expectations by select analysts,” contrasting with Nvidia’s usual comfortable beats. Wedbush’s Matt Bryson had called the setup a potential “sell-the-news” risk.

Korea’s PPI explosion to 6.9% from 4.1% confirms the semiconductor supply chain is now feeding inflation directly. The same chip demand driving Nvidia’s revenue is lifting producer prices across Asia.

Australia lost 18,600 jobs in April against a consensus gain of 16,700, and unemployment jumped to 4.5%. The RBA’s May hike to 4.35% looks increasingly like a policy error against a labor market deteriorating this fast.

Japan exports beat strongly at 14.8% versus a 9.3% consensus, but machinery orders collapsed 9.4% — the external sector is carrying an economy whose domestic investment is stalling. SpaceX filed for an IPO after the close, the largest private-company listing now in the pipeline.

04 What to watch today and this week

• Thursday: Nvidia post-earnings market reaction in the first 30 minutes determines whether the $91B guide was “good enough” or triggers a SOX rotation.
• Thursday: Walmart Q1 earnings before open — consumer spending read under $98 WTI and 3.8% CPI. Margin guidance with elevated transport costs is the focus.
• Thursday: US Initial Claims and Philly Fed Manufacturing — labor and factory reads after PPI’s 6.0% explosion last week.
• Friday: Trump swears in Kevin Warsh as Fed Chair — his first public statement sets the tone for the June FOMC and the rate-hike debate.
• This week: Iran negotiations entering “final stages” — if a deal materializes, oil drops toward $85 and every central bank’s inflation calculus resets overnight.

Frequently Asked Questions

Why did oil prices crash on May 20, 2026?

WTI fell 5.66% to $98.26 and Brent dropped 5.63% to $105.02 after President Trump said the administration is in the “final stages” of negotiations with Iran. Three supertankers left the Strait with full cargoes, the first significant commercial transit since the blockade began in late February. The decline triggered a broad equity rally and a retreat in Treasury yields from their 19-year highs.

What did Nvidia’s earnings show?

Nvidia reported Q1 revenue of $81 billion, beating consensus, and guided $91 billion for Q2. The company raised its dividend to $0.25 per share. Shares whipsawed after hours because the guidance, while above Street consensus, fell short of some whisper-number estimates. The setup reflects a market that has priced perfection into AI names, making even solid beats difficult to reward at the current multiple.

Why did UK CPI fall while PPI surged?

UK headline CPI eased to 2.8% in April because prior base effects and moderating food prices offset energy costs at the consumer level. But PPI input surged to 7.7% (consensus 5.9%), meaning factory-gate costs are accelerating at nearly double the expected rate due to crude oil. The gap suggests consumer inflation will re-accelerate in Q3 as producers pass through costs. This creates a policy trap for the BoE, where one MPC member already voted for a hike in April.

What happened to Australia’s labor market?

Australia lost 18,600 jobs in April, a sharp miss versus the consensus gain of 16,700. Full-time employment dropped 10,700 and the unemployment rate jumped to 4.5% from 4.3%. The participation rate fell to 66.7%. The data raises questions about the RBA’s surprise hike to 4.35% on May 5, which now appears poorly timed given the labor market is deteriorating faster than expected.

When does Kevin Warsh take over as Fed Chair?

President Trump will swear in Kevin Warsh on Friday, May 22. His first public remarks will be scrutinized for signals on whether the Fed’s next move is a hold, a hike, or a cut. Ed Yardeni has warned Warsh may need to raise rates at the July meeting to address “Bond Vigilantes” given PPI at 6.0% and the 30-year yield above 5%. Warsh called for a “new inflation framework” during his confirmation hearing.
