Hormuz MOU Chaos Sends Oil to -5% as Richmond Manufacturing Surges

Markets navigated a day of sharply conflicting signals on May 27, with the dominant story being a contested Iran-US framework for Strait of Hormuz reopening that whipsawed energy and risk assets. WTI crude collapsed 5.04% to $88.68/bbl — its steepest single-session drop in months — as Iranian state broadcaster IRIB released a 14-point draft MOU calling for commercial shipping to return to pre-war levels within one month. The White House flatly denied the document's authenticity, calling it 'a complete fabrication,' yet President Trump simultaneously warned he would restart strikes if talks fail, leaving traders to price a non-trivial probability of a genuine diplomatic off-ramp. Equities absorbed the cross-currents with near-flat closes: S&P 500 edged down 0.08% to 7,520.36 and Nasdaq 100 fell 0.36% to 29,973.57, reflecting relief on energy costs offset by rising yields.

Gold, which fell to two-month lows intraday on the Hormuz deal optimism, staged a partial recovery to close at $4,447.50/oz, up 0.18%, as the White House denial reintroduced geopolitical risk premium. The 10-year Treasury yield rose 2.2 basis points to 4.481%, pressured by a striking upside surprise in regional manufacturing data: the Richmond Fed's composite manufacturing index surged to +13 in May from +3 in April, the highest reading in nearly five years and a 9-point beat above the consensus forecast of +4 (Federal Reserve Bank of Richmond). Shipments jumped to +16 from -2, new orders climbed to +17 from +8, and services revenues rose to +14 from +9 — a broad-based acceleration that complicates any Fed pivot narrative heading into summer.

The RBNZ added a hawkish overlay to the global rates picture, holding its OCR at 2.25% only through Governor Anna Breman's casting vote after a 3-3 MPC split between holding and immediately hiking 25 basis points. All six members agreed future hikes are likely, and the bank revised its terminal rate projection to 3.28% by June 2029, with the September 2026 OCR track lifted to 2.51% from 2.28% and June 2027 to 3.07% from 2.62%. The RBNZ cited Middle East energy price pressures driving inflation to a projected peak of 4.3% in Q3 2026, and Goldman Sachs subsequently forecast back-to-back 25bp hikes in July and September. NZD/USD jumped roughly 0.64% on the decision, adding modest pressure to the US Dollar Index, which still nudged up 0.13% to 99.21.

Cross-asset implications are substantial: an oil-demand relief trade lifted equity valuations intraday, but the Richmond data and sticky yields argue against a near-term Fed cut, capping the upside for rate-sensitive growth stocks. Energy sector positioning remains bifurcated — a confirmed Hormuz deal could accelerate further crude declines, while any breakdown in negotiations would rapidly reverse Tuesday's move. Markets will scrutinize Thursday's core PCE print as the next hard inflation datapoint, with the Richmond beat ensuring any upside surprise will meaningfully reprice summer cut probabilities. The Hormuz situation demands daily monitoring: until either Washington confirms a framework or Tehran withdraws the draft, every IRIB bulletin carries crude-moving potential.
