President Trump threatened a destructive “economic D‑day” against Iran; markets reacted with oil rising from $86.20 to $86.70/bbl and US equities posting their largest decline in three weeks. 30‑year Treasury yields jumped above 5.25%, approaching a two‑decade high and signaling investor aversion to long bonds. US Treasury Secretary Bessent doubled long‑term buybacks to at least $4bn but markets remained unsettled, according to a non‑resident fellow at a Qatari think tank. The fellow flagged three structural pressures on long‑end bonds: an expanding federal deficit, heavy corporate issuance from AI firms, and an oil‑price inflation premium; he added that a Strait of Hormuz closure and Gulf output unlikely to return before early 2027 are tightening supply and feeding US inflation. US public debt topped $40tn this week, about two years earlier than expected, which the source attributed to war costs and prior tax cuts. The report also noted Gulf and East Asian economies—major Treasury holders—are under strain after recent Gulf restrictions (the UAE announced an indefinite embargo) and yen pressure, reducing marginal demand for US debt at a time Washington needs funding.
