As of close on April 9th, 2026
Markets are navigating a volatile mix of sticky inflation, geopolitics, and corporate restructuring. Core PCE inflation held at 3% (headline 2.8%), above the Federal Reserve target, with the Fed's March minutes showing a willingness for rate hikes. Oil markets swung sharply, with WTI down 16% to $93.98 on Tuesday after President Trump announced a two-week Iran ceasefire, though uncertainty persists as reports emerged later that day that the Strait of Hormuz was closed after a brief reopening due to Israel continuing their campaign in Lebanon. Cyber risk also escalated as the FBI, NSA, DOE, and CISA warned of Iran-linked attacks on US critical infrastructure. In tech and logistics, Amazon struck a new deal with the United States Postal Service to stabilize roughly $6B in postal revenue. In the media, Disney is planning up to 1,000 layoffs, mainly in marketing, amid consolidation under new CEO Josh D’Amaro. Lastly, Oracle appointed Hilary Maxson, former Schneider Electric CFO, as CFO to manage AI-driven cloud expansion amid rising debt.
