Oil cracks, on the eve of the test.

For two weeks the market’s problems traced back to one source — oil — so Tuesday’s near-3% drop in Brent is more than a commodity move. It eases the entire chain that drove the selloff, pulling the inflation impulse and the yield pressure with it. The trigger was a re-reading of the Iran picture: sanctions, however aggressive, disrupt supply less than a military escalation would, and Tehran’s foreign minister chose this moment to emphasise diplomacy and even sketch a framework for managing Hormuz. It is a genuine, if fragile, shift toward the softer side of the weekend’s crosscurrent. The timing matters, because it lands just as the week’s real tests arrive: the July PCE will show whether the Fed’s preferred gauge is still stuck in the mid-3s, and Nvidia’s results tonight will judge whether the AI leaders deserve their valuations after a bruising fortnight. A softer oil backdrop makes a benign outcome easier to imagine — but nothing is settled until the numbers print.

• Oil did the heavy lifting — Brent’s 3%-plus drop eased the inflation-and-yields worry that had dogged the tape.
• Chips recovered — the memory names bounced back, helping the Nasdaq lead a modest advance before Nvidia.
• Yields softened — the long end eased with oil, a welcome backdrop into the July PCE.

After Monday’s escalation, the diplomatic track pushed back. Iran’s foreign minister said that “Iran’s commitment to peace and stability is matched by steadfast diplomacy,” and pointed to a proposed framework covering a new shipping corridor, joint mine-clearing and the future management of the Strait of Hormuz — the most concrete outline of a workable arrangement in weeks. The oil market moved decisively on it: Brent fell more than 3% to a one-week low near $89, back below the $90 mark, as traders concluded that US economic sanctions, however aggressive, threaten supply far less than a military escalation would. The caveat remains important. Washington is still tightening the screws, threatening Tehran’s remaining trade partners, so the two tracks run in parallel and the framework is a proposal, not a signed settlement. But for the first time in a fortnight, the balance of Gulf news tilted toward resolution rather than away from it — and the whole global risk picture, from yields to equities, breathed easier for it.

Vault Wealth’s house view: this is the constructive signal we said we would need, and we treat it as the start of a case to ease our defensive stance — not yet the confirmation to act on it. Brent back below $90 relieves the trigger that took us defensive, and if the framework firms and oil holds lower, we will begin trimming the energy and gold hedge and re-adding measured risk. For today, with the PCE and Nvidia both landing, we keep the hedge and stay balanced and liquid: one good day on the diplomacy does not undo a fortnight of escalation, and the binary events could still swing the tape hard. Confirmation, then action.
