A one-two punch of hotter-than-expected US inflation data and a fresh surge in oil prices brought Tuesday’s record-chasing to an abrupt halt. The S&P 500 closed down 0.16% at 7,400.96 and the Nasdaq Composite fell 0.71% to 26,088.20 on May 12, 2026, as a hotter-than-expected April Consumer Price Index (CPI) sent semiconductor stocks sharply lower. In Europe, a political earthquake in London drove UK gilt yields to their highest levels of the year, dragging continental markets down 1–1.6% across the board. The Dow Jones Industrial Average bucked the trend modestly, rising 56 points to 49,760.56.
US Markets: CPI Breaks the Streak
April CPI: 3.8% — Highest Since May 2023
The session’s defining data point arrived before the open. The Bureau of Labor Statistics reported that the April Consumer Price Index rose 3.8% year-over-year — the highest annual rate since May 2023 and above the 3.7% consensus estimate polled by Dow Jones. Monthly headline inflation came in at +0.6%, in line with forecasts, while core CPI (excluding food and energy) rose 2.8% from a year earlier.
Energy was the primary driver. WTI crude surged 4.19% to settle at $102.18 per barrel, while Brent crude rose 3.42% to $107.77 — both continuing the climb triggered by the collapse of US-Iran ceasefire talks. Electricity prices jumped 2.1% month-over-month, food prices gained 0.5% MoM, and a 15% spike in tomato prices for the second consecutive month reflected drought conditions across North America.
Capital Economics chief North America economist Stephen Brown noted the read will make Federal Reserve policymakers more concerned about “renewed signs of food inflation accelerating, given the risk that higher gasoline and food prices together will further boost households’ inflation expectations.” Thomas Martin of Globalt Investments was blunter: “As these gas prices and other prices are higher, it’s going to crimp more and more people, so the setup is for there to be continued struggles for the consumer.”
Chip Stocks Take a Hard Breather
Monday’s semiconductor leaders became Tuesday’s biggest losers. The read-through was swift: hotter inflation → reduced odds of Fed rate cuts → rising discount rates → pressure on high-multiple growth stocks. Qualcomm (QCOM) plunged 13%, its worst session since 2020, while Intel (INTC) fell 8%, On Semiconductor (ON) and Skyworks Solutions (SWKS) each dropped more than 6%. The iShares Semiconductor ETF (SOXX) sank 5%.
Micron Technology (MU), which had surged 6.5% on Monday, reversed course and fell 3.6%. Advanced Micro Devices (AMD) fell 2%. The selling came after a historic run — Micron +37.7% last week and +53% in April — that had pushed the Philadelphia Semiconductor Index into technically overbought territory not seen since the late 1990s.
The “1999 debate” surfaced loudly on Wall Street. CNBC’s Michael Santoli noted that the semiconductor sector’s overbought reading relative to its 200-day moving average has only been exceeded twice in history — in early 2000, which coincided with a generational market peak, and in 1995. Bespoke Investment Group added that the only comparable period of S&P 500 records with so few stocks above their 50- and 200-day moving averages was “from late 1998 to early 2000.” This time, bulls argue the AI spend cycle is structurally different; bears say history doesn’t care.
One significant exception: Nvidia (NVDA) hit a fresh all-time intraday high in the morning session and held most of those gains, even as peers sold off. Citi analyst Atif Malik reiterated a Buy rating and $300 price target ahead of Nvidia’s May 20 earnings, estimating sales near $80 billion — above the $78.6B consensus — and projecting the 2028 data center semiconductor total addressable market has expanded to $851 billion, up 16% from prior estimates.
Health Care Leads, Apple Hits Record Close
Seven of eleven S&P 500 sectors closed positive on Tuesday — the selloff was concentrated rather than broad. Health care led all sectors at +1.93%, followed by consumer staples (+1.56%) and financials (+0.72%). Consumer discretionary was the worst performer at −1.06%, followed by information technology at −0.99%.
Apple (AAPL) closed at a new all-time record high of $294.80 (+0.72%), having also touched a fresh intraday record during the session — a notable divergence from the broader tech selloff that underscores how differently the market is treating mega-cap hardware/services names versus pure-play semiconductor stocks.
Among earnings movers: Vestis (+30%) surged after its fiscal Q2 beat and raised FY2026 EBITDA outlook; Zebra Technologies (+17%) after a Q1 EPS beat ($4.75 vs $4.25 est) and Q2 guidance above consensus; Ralliant (+14%) on an adjusted EPS beat of $0.57 vs $0.49 est. On the losing side, Under Armour (UAA) fell 14% after reporting revenue of $1.17 billion versus $1.68 billion expected — a significant miss that reflects deepening consumer spending pressure in discretionary apparel.
Kevin Warsh Confirmed as Fed Governor — Chair Vote Wednesday
A critical milestone in the Federal Reserve leadership transition came Tuesday. The Senate confirmed Kevin Warsh as a Fed Board of Governors member by a 51-45 vote, largely along party lines. The vote to confirm him as Fed Chair — the more consequential vote — was expected Wednesday. Warsh previously served on the Fed Board from 2006 to 2011, during the global financial crisis. His economic philosophy is considered more hawkish than outgoing Chair Powell, which could have significant implications for the rate trajectory in 2027 and beyond.

European Markets: UK Political Crisis Adds a Second Shock
European markets faced a compounding set of pressures on Tuesday: rising US inflation and oil prices feeding into global risk-off sentiment, and a domestically driven UK political crisis that sent bond yields surging and banking stocks tumbling.
Starmer Under Fire — UK Gilt Yields Hit Year Highs
The most dramatic story in European markets on May 12 came from Westminster. Prime Minister Keir Starmer faced mounting calls to resign as government ministers joined more than 70 Labour MPs demanding his departure or a timetable for it, following his party’s heavy losses in last week’s local council elections. The political uncertainty sent the UK 10-year gilt yield surging nearly 12 basis points to 5.126% — a sharp spike for a single session and its highest level this year.
Higher gilt yields weighed most directly on British banks, which rely heavily on stable funding costs and see their bond portfolios marked down when yields rise. NatWest fell 4.7%, Lloyds slid 4.3%, and Barclays dropped 4.1%. The selloff in UK financials was one of the sharpest single-day sector moves in Europe this year.
Continental Markets Retreat on CPI and Oil
Across the Channel, markets extended losses driven by the global macro headwinds — hot US inflation and surging crude oil — rather than UK-specific politics. The DAX fell sharply as Germany’s export-heavy industrial sector is particularly sensitive to energy cost pressures, and the FTSE MIB and IBEX posted losses of more than 1.5%.
| Index | Close | Change |
|---|---|---|
| STOXX Europe 600 | 606.63 | −6.16 (−1.01%) |
| FTSE 100 (London) | 10,265.32 | −4.11 (−0.04%) |
| DAX (Frankfurt) | 23,954.93 | −395.35 (−1.62%) |
| CAC 40 (Paris) | 7,979.92 | −76.46 (−0.95%) |
| FTSE MIB (Milan) | 48,990.98 | −673.97 (−1.36%) |
| IBEX 35 (Madrid) | 17,573.60 | −278.90 (−1.56%) |
What to Watch on May 13 (Wednesday)
- US April PPI: The producer price index is due before the open. Economists polled by Dow Jones expect a headline increase of +0.5% MoM, with core PPI expected at +0.4%. A second consecutive upside inflation surprise would reinforce the case for a higher-for-longer Fed funds rate. Check the EconPlex Economic Calendar for the release time.
- Kevin Warsh Fed Chair vote: The Senate is expected to vote on confirming Warsh as the next Federal Reserve Chair. A confirmed hawkish chair alongside persistent inflation would be a meaningful signal for rate-sensitive sectors.
- Earnings before the bell: Allianz, Birkenstock, Alibaba, and Nebius all report. Alibaba’s results will be particularly closely watched given the Trump-Xi summit context and US-China trade dynamics.
- After-hours movers from May 12: Nextpower (+10%, raised guidance), Karman (−11%, EPS miss), Resideo Technologies (−7%, soft Q2 guidance) will see their moves validated or reversed at Wednesday’s open.
- UK political situation: Will Starmer survive? Any Labour leadership vote or announcement of a departure timeline would create additional gilt market volatility and further pressure UK financials.
The session’s central message: the market’s AI-fueled immunity to bad news has limits. When the inflation signal is strong enough, and oil is above $100, even the chip sector’s momentum can be interrupted. Tuesday’s move was a correction within a bull market, not a reversal — but the CPI print raises the stakes for Wednesday’s PPI and puts the Federal Reserve‘s next move under intense scrutiny.
