Inflation Just Soared at the Fastest Pace Since 2023, and It Could Spell Trouble for Stock Market Investors

The article says U.S. CPI inflation rose at the fastest pace in three years, driven by higher oil prices amid the U.S.-Iran conflict. It cites CPI up to a 3.8% annualized rate in April and PPI up to 6% with energy up 22.7%. CME FedWatch shows a 68% chance of a rate increase by end-2026, which could pressure the S&P 500.

Near-term: CPI/PPI prints and FedWatch-implied odds can reprice rates quickly; follow-through risk persists into late 2026.
Bearish for broad equities via higher-for-longer rates; neutral for CME as an index/data provider.

CME’s FedWatch is being used as the market’s primary read-through for Fed tightening odds, supporting higher trading/hedging activity around rates.

The article cites CME Group’s FedWatch tool showing a 68% probability of an end-2026 rate increase, shaping rate expectations traders act on.

Likely limited direct impact on CME shares; the bigger effect is on rates-linked positioning and volatility where CME data is referenced.

Background

After aggressive tightening in 2022–2023, the Fed began cutting in 2024; the article argues a new oil-price shock could force a reversal.

Why it matters

Rising CPI and PPI increase the probability of renewed tightening, which historically compresses equity valuations and raises borrowing costs.

Market relevance

The core tradable signal is the repricing of Fed policy odds from oil-driven inflation prints, with broad equity downside risk.

Market effects

Higher rates typically pressure rate-sensitive sectors (growth/long-duration equities) and credit-sensitive names; energy-driven inflation can also lift input-cost beneficiaries while hurting margins for others.

Primarily US macro-driven risk-off; spillover into global equities via USD rates and risk premia.

Iran/Strait of Hormuz shipping disruption raises global oil-price risk, feeding inflation expectations and cross-asset volatility.

Alternative perspectives

If the oil shock fades faster than expected, the Fed could still avoid renewed hikes, limiting equity downside despite the headline CPI jump.

The article frames inflation as oil-led; watch core measures and wage/services inflation to gauge whether the shock is transient or broad-based.

Key entities

  • Kevin Warsh

    Sworn in as new Fed chairman; the article links his mandate to potential renewed rate hikes.

  • CME Group FedWatch

    Used to estimate 68% odds of an end-2026 rate increase based on fed-funds futures.

  • Strait of Hormuz

    Shipping disruption risk is cited as a driver of sustained oil-price pressure.

CME Group’s CEO, Duffy, warns of systemic risk from new crypto ‘perps’

CME Group CEO Terry Duffy told a conference that U.S. regulators are creating systemic risk by approving perpetual crypto futures (“perps”), which he said typically use high leverage (often up to 50:1) and automatic liquidations. Reuters reports Coinbase and Kalshi plan to launch perps after CFTC approval. Duffy criticized the CFTC’s case-by-case process and said institutional demand is limited.

CME dropped 3%+ (about 9% over two days), Cboe fell 8% (week losses 16%+), and Intercontinental Exchange and Nasdaq also declined.
