Oil Plunges 11% as Strait of Hormuz Reopens, Central Banks Delay Rate Decisions

Iran's reopening of the Strait of Hormuz triggered an 11% oil price collapse in late April, prompting major central banks to pause planned rate hikes. The ECB, Fed, and BOJ are assessing whether the energy shock will produce lasting inflation or quickly dissipate, while equity markets rallied on de-escalation news.

Oil prices collapsed 11% after Iran reopened the Strait of Hormuz, ending a supply crisis that had threatened global energy markets. The sudden de-escalation forced central banks to recalibrate monetary policy as the geopolitical shock unwound faster than expected.

The European Central Bank postponed its April rate decision to June, citing uncertainty over the oil shock's duration. "Given higher uncertainty at the moment, June is a better moment than April" to decide whether a rate response is necessary, said ECB policymaker Alexander Demarco.1 ECB board member Olaf Sleijpen affirmed the bank "will act if needed to keep inflation at target."2

The Dallas Federal Reserve noted that inflation expectations could moderate quickly with the strait's reopening, suggesting the oil spike's long-term impact may be limited.3 The assessment contrasts with earlier warnings from IMF Chief Economist Pierre-Olivier Gourinchas, who cautioned the crisis "could rival that of the 1970s."4

Equity markets surged on the de-escalation, with technology stocks and airlines posting sharp gains as investors priced in lower fuel costs and reduced geopolitical risk. Commodity-exposed sectors declined as energy prices retreated from recent highs.

The policy pause marks a shift from the hawkish stance central banks held during the supply disruption. Banks must now determine whether recent inflation readings reflected a temporary shock or signaled broader price pressures requiring intervention.

The Bank of Japan also signaled caution on rate hikes as it monitors the energy market's stabilization. All three major central banks face the challenge of responding to rapidly shifting conditions while avoiding policy errors.

Market volatility subsided as the immediate crisis faded, but policymakers remain alert to renewed geopolitical flare-ups that could reverse the oil price decline. The swift market reaction demonstrates how quickly sentiment can shift on supply-critical chokepoints.

AI Boom Hits a Fork: Slowdown Calls Clash with Capex Confidence as Markets Get Nervous
Dario Amodei's repeated calls for a global slowdown in frontier AI development, echoed by Microsoft's new humanist AI code of conduct and FTC antitrust caution, are being publicly rejected by Nvidia and Meta leadership even as hyperscaler spending draws fresh skeptical scrutiny (Wachter's analysis, Burry-style overbuilding worries) and weak guidance from Adobe and a post-slowdown-comment selloff in GE Vernova signal investor jitters. Meanwhile wealth and security effects of the AI race keep compounding — Zhang Yiming's fortune surging on AI-driven ByteDance value, a Chinese hacking firm weaponizing AI against stolen government secrets, and low-quality AI-generated products (an AI sitcom, a spam-flooding agent platform) fueling backlash even as adoption races ahead.

These cannot both be true for the same entity at the same point in time. The magnitude of the discrepancy (a factor of ~10^9) rules out rounding, unit conversion, or methodological differences.
