Yields bite the AI leaders.

The sequence is telling. An oil shock on Monday fed a yield spike, and by Tuesday multidecade-high long yields had done what they eventually do to richly valued growth — compressed it, with the AI leaders that carried the market to its record now leading it down. The irony is that the week’s marquee fear eased at the same time: Home Depot’s comparable sales beat expectations and its guidance was reaffirmed, suggesting Friday’s retail-sales drop may have overstated the consumer’s weakness. But a reassuring consumer cannot offset a repricing of rates, and with President Trump ruling out an Iran truce, the oil bid underpinning those yields shows no sign of fading. Today’s FOMC minutes will be parsed for how a divided Fed views this exact mix — cooling core inflation, but firmer energy and a softening labour market.

• The AI leaders cracked — Nvidia, Micron and Broadcom were the heaviest weights as multidecade-high yields hit the priciest stocks.
• The consumer reassured — Home Depot’s beat and reaffirmed guidance were the day’s clearest positive, largely ignored by the tape.
• Oil and yields stayed bid — crude’s third straight gain and a decades-high long end kept the pressure on valuations.

The diplomatic door that looked ajar two weeks ago has swung shut. President Trump said he would not try to revive the stalled interim truce with Iran — a hardening that mirrors Tehran’s own weekend signal that it may move to an “offensive” posture in the Strait of Hormuz. With both sides digging in, the diplomacy premium that had been draining out of oil has reversed: crude rose for a third straight session, WTI above $85 and Brent near $91, and the strait remains largely blocked, only a handful of vessels crossing daily against roughly 120 before the war. The knock-on into markets is now clear and mechanical — firmer oil feeds the inflation worry, which lifts long yields to multidecade highs, which in turn compresses the richly valued equities that led the rally. For the Gulf, the immediate effect is a firmer oil price against a still-constrained export picture, but the larger point is that the conflict, not the data, is once again setting the tone for global risk.

Vault Wealth’s house view: we acted on our $90 Brent trigger on Tuesday and hold that more defensive stance today. The energy and gold hedge stays lifted, and we are not adding equity risk into a rates-and-oil squeeze, however reassuring the consumer data looks. We stay balanced and liquid: Home Depot’s beat tells us the economy is intact, so this is about managing a valuation and geopolitical repricing, not a recession. A credible return to diplomacy would let us reverse the hedge and re-engage; a further escalation would keep us defensive.
