President Donald Trump announced what he called an "economic D-Day" to intensify economic isolation of Iran, warning that countries providing financial or logistical support would face severe consequences. The threat of secondary sanctions could pressure foreign banks and businesses beyond Iran and further complicate negotiations amid prolonged U.S.-Iran tensions and strain in the Strait of Hormuz. Prediction-market pricing now indicates a lower likelihood that a 2026 U.S.-Iran deal would include Iran Reconstruction Funding, while provisions such as uranium-enrichment caps or stockpile surrenders also appear less likely. Observers will watch Iran's response, possible retaliation, the roles of Javad Zarif and mediators from Qatar and Pakistan, changes in U.S. policy rhetoric, and reactions from countries exposed to secondary sanctions.
