For the first time since the Red Sea diversion began in late 2023, three of the ten globally-named maritime chokepoints — Strait of Hormuz, Bab-el-Mandeb, and the Taiwan Strait — are sitting at elevated-or-higher combined stress on the same observation cycle. The drivers are uncorrelated (Iran-tied tanker activity in the Gulf, Houthi missile-and-drone targeting south of the Suez, PLA exercise tempo across the median line), but the equity exposures overlap heavily: ZIM, FRO, STNG, TSM, NVDA and the energy complex all sit on at least two of the three risk axes. When independent geopolitical drivers route through the same forward-earnings tape, the convergence is the story.

Two paths falsify this read. First: if the conflict baseline at any one chokepoint normalizes (Houthi pause, Iran de-escalation, PLA exercise tempo cooling) within the next 14 sessions, the convergence collapses to a two-of-three configuration the desk has previously called "live but not sufficient." Second: weather is currently amplifying the stress score at Bab-el-Mandeb and Hormuz. If the seasonal pattern unwinds and the conflict baseline stays static — i.e. the visible stress was largely meteorological — the equity tape should rebound with the marine forecast, not against it. Watch the open-meteo Marine API readings against the conflict tier; divergence between them is the early signal that this is unwinding.
The desk treats two chokepoints as independent when (a) the conflict drivers are non-overlapping in actor, geography, and motivation, and (b) the weather systems do not share a synoptic origin. Hormuz, Bab-el-Mandeb, and the Taiwan Strait all clear that bar today: Persian Gulf, Red Sea / Gulf of Aden, and East Asia respectively. The combined stress score (weather 0–100, weighted-max with curated conflict baseline 0–100) is read on an 8-hour cadence from the open-meteo Marine + Weather APIs. A convergence requires three or more chokepoints to sit ≥40 on combined stress within the same 72-hour window. As of the most recent ingest, that threshold is met. Rigor: the harness for this signal is queued — directional read, not validated alpha. The desk is publishing on the strength of the structural read, not a back-tested edge.

The core issue remains readable for sharing and top-of-funnel trust. Pro access should add audit trails, named tickers, watch lists, and backtest appendices, not hide the existence of the claim.
