US 10-Year Yield Above 5% as Brent Tops $100 on Iran Standoff
中文标题
美国10年期国债收益率升破5%，布伦特原油因伊朗僵局突破$100
Core conclusion · Tlines extraction
Rising oil prices, strong US PMI data, hawkish Fed Governor Barr comments and weak demand at a five-year Treasury auction pushed the US 10-year yield back above 5.0%, pressuring global equities and lifting the dollar. Brent rose 4.2% to US$103/bbl after Iran's president said the waterway would not reopen while sanctions and the blockade remain. The AUD fell 1.1% to 0.7039. Australian yields eased ahead of the labour market report.

Key arguments
- Higher oil prices, robust US PMIs and weak five-year auction demand drove the 2-year yield up 14bps and the 10-year up 15bps, back above 5.0%
- Fed Governor Barr said further policy adjustments are likely needed, with risks skewed to the upside
- Iran's President said Iran will not reopen the waterway while sanctions and the US blockade remain, nor relinquish nuclear development rights
- Australian yields fell ahead of the labour market report, with swaps pricing a September hike near 86% and a November move fully priced
Key numbers

Main risks
- The White House denied reports of a 90-day diesel export ban, but officials said they were working with refiners to voluntarily curb exports, leaving the policy path unclear
- Expectations for a breakthrough at the Trump-Xi meeting remain low
- US September PMI data are preliminary and may be revised, and the effect of higher oil prices on inflation remains uncertain
Corresponding source evidence
Australian government bond yields moved lower ahead of today’s labour market report.
Governor Barr’s comments also supported, noting “In my base case, further policy adjustments are likely to be needed to ensure inflation comes down to target in a timely fashion” with risks skewed to the upside.
European equities were also weaker, with the Euro Stoxx 50 down 0.4%, while the FTSE 100 was unchanged.
