π₯ Key News This Hour
1. Iran Announces Hormuz Strait Transit Suspension Iran’s Persian Gulf Strait Affairs Authority states the strait is not safe for navigation due to US “aggressive actions,” and transit will resume only after “order is restored.” ~20% of global oil passes through the strait; oil prices jumped on the news.
2. Three Fed Officials Support Rate Hike, Internal Hawkish Pressure Rising Hammack, Kashkari, and Logan voted against this week’s hold decision. “Fed whisperer” Nick Timiraos notes the three provided more rationale for tightening than the FOMC statement. Logan emphasizes underlying inflation near 2.5% excluding recent shocks.
3. US 10-Year Treasury Yield Rises to 4.7388% Highest level since January 2025, as bond markets react to hawkish Fed signals.
4. Amazon Surges 15.2% Post-Market β Largest Gain Since 2012
5. US Reported to Intervene in JPY on Friday Sources say the US Treasury has notified banks of possible JPY intervention on Friday. USD/JPY dropped ~100 pips. Japan previously suspected of spending $53B+ intervening in FX markets on Thursday.
6. US-Iran Tensions Continue to Escalate Treasury Secretary Bessent announces global pursuit of Iranian assets; UAE strongly condemns Iran’s aggressive attack on Kuwait; Indian FM speaks with Iranian FM, urging avoidance of attacks on commercial shipping.
π§ Situation Assessment
Iran’s closure of the Hormuz Strait is the biggest black swan event this hour. ~20% of global oil transits through the strait; if the blockade persists, crude could quickly test $90 or higher.
Three dissenting votes for a rate hike at the Fed is extremely rare, signaling substantive buildup of hawkish pressure. Combined with the 10Y yield breaking above 4.74%, markets are repricing the rate path β higher for longer is back in focus.
The US Treasury directly intervening in JPY is unprecedented. Combined with Japan’s suspected $53B intervention, the USD/JPY dynamic enters a new phase. Whether intervention can reverse the trend remains doubtful.
Gold pulled back from above $4,100 to $4,050, pressured near-term by dollar strength. But the tug-of-war between geopolitical risk premium and rate expectations will persist, limiting downside.
