The dominant market-moving signal in this window is the escalation of the Iran-US crisis, with Iran closing the Strait of Hormuz and high-stakes talks beginning in Switzerland. This is a major escalation from the previous window, where the narrative was stable. The Strait of Hormuz closure directly threatens global oil supply, with a fifth of global oil and liquid gas supplies transiting the waterway. This is corroborated by multiple sources: The Guardian, Al Jazeera, and GDELT all report the closure and the start of talks. The talks, involving US VP Vance and Iranian leadership, are a counter-signal that could de-escalate, but the closure itself is a bearish development for oil supply. The Ukraine-Russia conflict also shows escalation, with Ukrainian strikes on Russian oil infrastructure in Crimea and the Kerch Strait area, including fuel depots and refineries. This is corroborated by multiple Bluesky posts and GDELT. The Kerch ferry crossing was hit, and fuel sales in Crimea are suspended. This adds to upward pressure on energy prices and is bearish for Russian-linked assets. A survey showing 92% of Israelis believe Iran won the war is a negative sentiment indicator for the US-Israel alliance and could weigh on defense stocks. The TSMC CoPoS substrate glass technology news is a positive for semiconductor cost reduction, but is secondary to the macro geopolitical signals.
