Oil and Yields Squeeze Markets as Trump Rejects Iran's Hormuz Proposal and Rate-Hike Bets Build
Asian equities slipped Monday as Brent hit $107 and Treasury yields climbed toward two-decade highs, after Trump rejected Iran's proposal to reopen the Strait of Hormuz. With a 68% implied chance of an October Fed hike and a packed data week ahead, markets are bracing for further tightening.
What happened
Share markets across Asia were mostly lower on Monday, Sept 28, 2026, as oil prices climbed on doubts the United States and Iran will reach a truce over the Strait of Hormuz, keeping bond markets under pressure ahead of a week packed with economic data, per CNA. Over the weekend, US President Donald Trump rejected an Iranian proposal to reopen the strait, claiming Tehran was "desperate to make a deal," while Iran stuck to a seven-day proposal and said it would not soften its conditions; Trump said talks would continue this week, per Axios via The Economic Times.
Brent futures rose 2.7% to $107.16 a barrel, gains of almost 18% so far this month, while US crude futures added 1.9% to $94.16 a barrel, according to CNA/Reuters. The Economic Times/Bloomberg version put Brent up 1.5% at about $105.90. A dearth of refining capacity has lifted diesel prices to all-time highs far above crude, raising the risk that inflation becomes embedded in pricing and wage decisions, and Trump said he is thinking "very seriously" about a ban on diesel exports.
Central banks have responded with rate hikes. The Reserve Bank of Australia is likely the next to tighten when it meets Tuesday, and markets imply a 68% chance the Federal Reserve hikes for a second straight meeting in October, with around 90 basis points of tightening priced out to late next year, per CNA/Reuters. Traders are fully pricing at least one more 25 basis-point hike before year-end, following the Fed's first hike since 2023 earlier this month, per the Economic Times/Bloomberg report.
Yields moved higher across the curve. The 30-year Treasury yield nudged up to 5.5173%, near its highest since 2004, having climbed 27 basis points this month, while two-year yields have shot up 55 basis points this month, per CNA/Reuters. The 10-year Treasury yield rose four basis points to 5.20% in Asian trading, per the Economic Times/Bloomberg report. Last week the average yield on a gauge of global bonds climbed above 4% for the first time since 2007.
Equities were mixed to lower. Japan's Nikkei went flat; South Korea's market slid 2.0%; MSCI's broadest Asia-Pacific index outside Japan eased 0.6%; and Chinese blue chips slid 1.9% to a one-year trough after US lawmakers introduced legislation Friday to bar Chinese-made components from sensitive government AI data-centre systems, per CNA/Reuters. S&P 500 futures fell 0.3% and Nasdaq futures shed 0.7%, while European futures firmed, with EUROSTOXX 50 futures up 0.3%, DAX futures up 0.2% and FTSE futures up 0.2%.
In currencies and gold, the dollar index hit two-month peaks at 101.39; the euro fell to $1.1383, down 2.0% this month; and the dollar rose 0.3% to 157.75 yen after Japan's Finance Minister Satsuki Katayama said Trump voiced concerns about yen weakness, per CNA/Reuters. Sterling sat just above three-month lows at $1.3240, helped by hawkish comments from Bank of England Governor Andrew Bailey. Non-interest-bearing gold fell 2.2% to $4,192 an ounce, down more than 4% this month, though the Economic Times/Bloomberg version put gold down 0.5% at about $4,260 an ounce.
Why it matters
The combination of $107 Brent, 30-year Treasury yields near two-decade highs and a global bond gauge above 4% for the first time since 2007 marks a broad repricing of the cost of money across every asset class. Central banks are being forced to respond: the Fed's first hike since 2023 earlier this month is being followed by a 68% implied probability of a second straight hike in October, and the Reserve Bank of Australia may tighten as soon as Tuesday. The diesel squeeze adds a second channel of inflation risk, since refining bottlenecks are pushing fuel prices far above crude and raising the chance that energy costs feed into wage and pricing decisions. The geopolitical overlay compounds the pressure: Trump's rejection of Iran's seven-day proposal to reopen the Strait of Hormuz, with talks set to resume this week, keeps supply risk priced into oil. The data calendar sharpens the stakes, with the Atlanta Fed's GDPNow measure forecasting 5.0% growth this quarter and Friday's September payrolls report forecast to show a gain of 85,000 jobs with unemployment holding at 4.1%, per CNA/Reuters.
How it is being covered
The story is carried by 31 outlets, split 25% left, 55% centre and 20% right, with 17 of 20 rated outlets at high or very high factuality, per ground.news. Coverage is broad and no blindspot was flagged, with both the geopolitical and rates angles appearing across the political spectrum. The two anchor reports, from CNA/Reuters and the Economic Times/Bloomberg, differ mainly on intraday readings, with Brent quoted at $107.16 versus about $105.90 and gold at $4,192 versus about $4,260.
What to watch
The Reserve Bank of Australia's decision on Tuesday is the first test of whether central banks follow through on the tightening now priced into markets. Iran-US talks resuming this week will determine whether the Hormuz proposal is revived or the oil premium builds further. Friday's September payrolls report, forecast at 85,000 jobs with unemployment at 4.1%, will shape expectations for the Fed's October meeting, where markets imply a 68% chance of a hike. Trump's consideration of a diesel export ban is a policy wildcard for fuel prices, and UK police are investigating a potential terrorism incident after five men were arrested near an air base used in US strikes on Iran, with Trump saying the suspects were "looking to do big damage" to the facility, per the Economic Times/Bloomberg report.
