Iran says it will keep key oil route shut after Trump threat to Oman

Fact-check index: 74/100 — Core wire-service claims (Ghalibaf's Hormuz statement, Nikkei/European market drops, bond-yield surge) are accurately sourced and quoted from linked outlets, but several claims rely only on aggregator headlines with no body text, and the analytical 'hypothesis' callout draws inferences not explicitly stated in those headlines.

• Ghalibaf said Tuesday that forces will keep the Strait of Hormuz closed until the US meets obligations under the Islamabad memorandum, which Washington has failed to honor — Matches Washington Times source almost verbatim; source calls the memorandum 'defunct', a detail the article omits but doesn't contradict.
• 'The statement hardens Tehran's position as the standoff spreads into global markets' — Editorial framing/inference by the article, not stated in the Washington Times source; plausible but not directly sourced.
• Trump threatened last week to bomb Oman, the discreet broker between Washington and Tehran — Only a Gamereactor UK headline is available ('Trump escalates... threats to bomb United States-allied Oman'), confirming the threat but not the 'last week' timing or the 'discreet broker' characterization, which come from the article's own prior coverage rather than this source.
• Japan's Nikkei closed lower Tuesday amid the Middle East stalemate — Matches صحيفة مال headline exactly.
• European shares slipped as oil prices and bond yields surged on the same fears — Matches WTVB headline closely.
• Bond markets from the US to Japan were hit by inflation and fiscal worries compounding the geopolitical shock — Matches Reuters headline ('whacked as inflation and fiscal worries take hold').
• Global sentiment weakened further as yields kept climbing — Matches RTTNews headline ('Surging Bond Yields... Weaken Sentiment').
• Hypothesis: investors pricing in prolonged closure because yields rose in tandem with the equity selloff rather than as a safe-haven counter-move — An inference built on headline-only sources; neither Reuters nor RTTNews headline text explicitly states yields moved in tandem with equities rather than as a safe-haven hedge — this is the article's own analysis, appropriately labeled as a hypothesis but not established by the cited sources.
• Reuters attributes part of the yield surge to pre-existing inflation and fiscal concerns unrelated to Hormuz — Consistent with Reuters headline framing yield moves around 'inflation and fiscal worries.'
