Overnight into Wednesday 2 September 2026, the Hormuz risk premium stepped higher again. Renewed US airstrikes on Iranian targets near the Strait — described by CENTCOM as hitting IRGC assets linked to shipping attacks, mine-laying and air defence — were followed by reports that Iran struck US bases and allies in Jordan, Bahrain and Kuwait. Brent, which was around $92 when this article first published on 1 September, has been trading in a roughly $95.4–$95.7 area in early Asia/London hours (Trading Economics around $95.63; CNBC Brent November near $95.42), with some prints edging toward $96. The transmission is unchanged: Hormuz risk → oil → inflation stickiness → yields and the Fed → sterling and the FTSE. This is an update to the live story, not a second article.
Overnight Update (2 September 2026)
Markets are pricing a wider kinetic loop, not just Monday’s tanker report. After the UKMTO notice that a vessel leaving Hormuz had been struck by three projectiles, the US Central Command said fresh strikes followed recent IRGC attempts against commercial shipping in the strait and against American service members. Multiple outlets, including CNBC citing Al Jazeera, reported Iranian drones and missiles toward Kuwait, Jordan and Bahrain. President Trump, in a Truth Social post reported by CNBC, said he was “not trying to force Iran to the bargaining table” and claimed a stronger US position over Hormuz — language that keeps the de-escalation path thin for now.
Market reaction into the London morning
Oil: Brent futures were indicated around the mid-$95s early Wednesday — roughly $95.4–$95.7 depending on the print — after Tuesday’s surge from the ~$92 area used in the original lead. Trading Economics showed Brent near $95.63 on 2 September; CNBC had November Brent near $95.42 at 1:43 a.m. ET, with WTI October around $90.63. Some Asian session prints and secondary reports ran closer to $96. Treat those as a range, not a single tick.
Rates and Fed odds: The US 10-year yield has been around the 4.80–4.81% area (Reuters-fed Asia reports cited an intraday high near 4.81%), a multi-year high zone that keeps the Warsh/Jackson Hole inflation story live. CME FedWatch September hike odds remain in a roughly 67–70% band across recent prints (mid-to-high 60s into Tuesday; some Wednesday Asia copy nearer ~70%). Friday’s US payrolls remain the next hard labour catalyst before the 15–16 September FOMC.
Equities: Asia sold off hard on the oil-yield combo. Japan’s Nikkei was indicated down about 2–2.6% (some feeds nearer 2.9%); South Korea’s KOSPI around 3% lower (some opens nearer 4%). Wall Street on Tuesday already showed the rates/oil squeeze: S&P 500 roughly −0.7%, Nasdaq about −1%. London’s open will again split the FTSE story — energy majors can firm with crude while the index faces a higher discount rate.
Same chain as 1 September: constrained Hormuz supports oil; firmer oil supports the inflation-stickiness case Fed Chair Kevin Warsh made at Jackson Hole; that supports front-end yields and the dollar; the dollar can pressure GBP/USD; higher yields can weigh on the FTSE even when Shell and BP outperform the headline.
What Happened?
The United Kingdom Maritime Trade Operations agency (UKMTO) said a tanker reported being struck by three projectiles while sailing out of the Strait of Hormuz, about 17 nautical miles east of Khasab in Oman. The incident was timed around 20:00 UTC on Monday. UKMTO reported no casualties and no environmental impact. Shipping outlet Splash247 named the vessel as the Liberia-flagged Senegal Prosperity, though UKMTO’s public notice did not itself confirm identity, flag or ownership.
The strike follows the first direct US-Iran exchange of fire in more than a month. US forces hit Iranian rocket launchers on Larak Island, a control point in the strait, after Washington said Tehran was preparing to deploy sea mines. Iran then attacked two US air bases in Jordan. President Donald Trump told Fox News there would be a further response.
Hormuz has been constrained since Iran shut it after US and Israeli attacks on 28 February 2026. Before the war it carried about a fifth of global oil supplies. Mediators including Qatar and Oman have not broken through. Data from Kpler, reported by Reuters and CNBC, showed visible commodity vessels transiting the strait falling to around five a day over the weekend. Some tankers have also been sailing dark, so “visible” traffic is not all traffic — but five ships a day is still a choked artery.
Why Markets Reacted
Markets are not pricing one hull. They are pricing the return of kinetic risk on a route that has already been disrupted for six months. A tighter oil market can lift energy costs. Higher energy costs can keep inflation sticky. Sticky inflation can keep central banks from easing — and, in the United States this month, can even revive a hike.
That is why the Hormuz news is being read alongside Fed Chair Kevin Warsh’s Jackson Hole speech on 28 August. Warsh said the Fed must be confident that underlying inflation is moving to its 2% target “clearly and at sufficient speed.” Otherwise, “we have work to do.” He added that recent softer PCE and CPI readings do not show that underlying trends have “meaningfully improved.” July PCE was 3.7% headline and 3.3% core. The federal funds rate was last held at 3.50-3.75% on 29 July. CME FedWatch on Monday put the probability of a 25-basis-point rise at the 15-16 September meeting at 66.1%, nearly double the chance before he spoke.
The committee is not of one mind. Treasury Secretary Scott Bessent told CNBC on Monday that this looks like a supply shock, and that traditionally “you don’t raise into a supply shock” unless second- or third-order effects appear. Citigroup still sees no September hike. For now the argument is being settled in the bond market.
How London Markets Opened
By mid-morning in London the rates tape was the transmission. The US 10-year yield was around 4.78%. UK 10-year gilts were near 5.21%, with the two-year around 4.59%. Japan’s 10-year government bond yield printed 3.00%, a level not seen since 1996, as oil-linked inflation fears fed a global sell-off in sovereign debt. Higher yields raise the discount rate on equities and, when they are driven by hike odds, tend to support the dollar.
Sterling followed that dollar bid. GBP/USD was around 1.35, the lowest since mid-August, down about 0.11%, and EUR/USD near 1.1597, down about 0.22%, around 09:41 BST. The pound is not in a rout; it is giving modest ground to a dollar that now has both a geopolitical and a policy reason to be bid.
The FTSE 100, reopening after the late-August bank holiday, was around 10,738.92 at 09:27 BST, down 85.34 points or 0.79%. Germany’s DAX was near 26,096.58, off 0.62%. Wall Street does not open until later; Monday’s US close already showed the same mix, with the S&P 500 down 0.33% at 7,686.14, the Nasdaq down 0.12% at 26,370.89 and the Dow down 0.70% at 53,185.90.
Gold is the tell that this is a rates story as much as a war story. COMEX gold was around $4,322, about a three-week low, down 0.67%. When tankers are hit, bullion often catches a safe-haven bid. This morning it is not. Higher expected US rates after Warsh are dominating the geopolitical impulse.
UK shop-price inflation, in a British Retail Consortium survey, rose to 1.5% year on year in August, with food at 2.8%. That is background, not the morning’s catalyst.
What It Means for Oil, Sterling and Equities
The useful way to read the tape is as a sequence, not as four unrelated screens. Constrained Hormuz supports oil. Firmer oil supports the inflation-stickiness argument Warsh is making. That argument supports front-end yields and the dollar. The dollar pressured GBP/USD this morning. Higher yields and a cautious open pressured the FTSE 100, even though London’s index contains large oil producers that can benefit if crude stays elevated. A weaker headline index and firmer energy names can coexist.
Eurozone August flash HICP was due at 10:00 BST, consensus around 3.3% after 2.9% in July.
Bull Case and Bear Case
The bull case for risk assets would be de-escalation: fewer strikes, a mediator opening on Hormuz, or evidence that barrels are still leaving the Gulf even when AIS-visible traffic looks thin. A weak US jobs report later this week could also cut September hike odds. Bessent’s warning not to hike into a supply shock is the core of that view.
The bear case is another hit to shipping, damage to Gulf energy infrastructure, or a Warsh Fed that delivers in September because underlying inflation has not “meaningfully improved.” In that world, $92 Brent is nearer a floor than a spike.
What Happens Next
- Further UKMTO reports of vessel strikes, and whether the Senegal Prosperity naming is confirmed.
- Transit counts through Hormuz.
- US August payrolls, then CPI, into the 15-16 September FOMC.
- Euro-area inflation flash (10:00 BST).
- Whether Japan’s 3% 10-year yield is a one-print event or a new global anchor for long rates.

The takeaway for 2 September is practical. Overnight escalation has lifted Brent from the ~$92 print in the original lead into a mid-$95s range, with the US 10-year near 4.81% and September Fed hike odds still in the high-60s to ~70% area. Hormuz risk, oil, inflation stickiness, yields and UK risk assets are still one story. Watch the next military/UKMTO update, Hormuz transit counts, and Friday’s US payrolls – those will decide whether $95 is a scare spike or the new floor under London’s tape.
