US and Iranian negotiators have announced a framework deal aimed at ending the prolonged conflict, triggering a broad risk-on rally in global equities and a sharp drop in crude oil prices. The oil move reflects two dynamics simultaneously: (1) a reduced geopolitical risk premium on supply disruption and (2) the prospect of Iranian barrels — potentially 1-2 mb/d — re-entering global markets if sanctions are eased as part of any deal. The details, timeline, and verification mechanisms of the framework remain unclear, and markets are pricing in a best-case scenario.

The key watch items are: whether Congress or the UN must ratify any agreement (which could stall implementation), how quickly Iranian oil actually flows, and whether OPEC+ responds defensively with output cuts to defend price. Energy equities (XLE, XOM, CVX) face a direct headwind if the oil move is sustained, while airlines (UAL, DAL), transports, and consumer discretionary stand to benefit from lower fuel costs. This is a headline-driven move with significant reversal risk if the 'framework' frays on details.
