Oil and gold prices extended their sharp gains on Wednesday, propelled by escalating geopolitical tensions across the Middle East and Asia, while global equity markets treaded cautiously ahead of the release of critical US consumer price index (CPI) data that could shape the Federal Reserve’s next move on interest rates.
Commodities Rally on Supply Fears
US crude oil rose 0.89 per cent to $83.94 a barrel, while Brent crude advanced 0.78 per cent to $89.60 per barrel. Both benchmarks settled more than $1 higher on Tuesday, marking their highest closes since July 31 and extending a rally that saw prices jump about 5 per cent on Monday. The surge reflects growing anxiety over potential supply disruptions following a series of attacks on shipping in the Red Sea and the Persian Gulf.
Spot gold, the traditional safe-haven asset, climbed 0.46 per cent to $4,387.03 an ounce, as investors flocked to bullion amid uncertainty over the conflict between Iran and the United States.
Escalation in the Middle East
The geopolitical flashpoint centres on Yemen’s Iran-aligned Houthi rebels, who have intensified their campaign against commercial shipping in the Red Sea and Gulf of Aden. On Tuesday, Yemen’s transport ministry confirmed that four crew members of an Egyptian-owned vessel were killed in a Houthi attack—the first fatalities from Houthi strikes on shipping since the Iran war began on February 28, 2026. The US military separately reported that it had struck a container ship attempting to sail toward an Iranian port, heightening the risk of a wider naval confrontation.
The war between Washington and Tehran shows no signs of abating, despite repeated public claims by US President Donald Trump that a deal is imminent. In a note to clients, Kyle Rodda, senior financial market analyst at Capital.com, observed that “the lack of substantial news or progress in talks, with Iran doubling down on its commitment to govern the Strait of Hormuz, is keeping the risk for oil prices skewed to the upside.” The Strait of Hormuz, through which about one-fifth of the world’s oil passes, remains a critical chokepoint that any escalation could directly threaten.
Asia’s Security Flashpoints
Tensions are also flaring in East Asia. North Korea launched a ballistic missile off the Korean Peninsula’s east coast early Wednesday, a provocation that came just days before major joint military exercises between Seoul and Washington—manoeuvres that Pyongyang has long denounced as rehearsals for invasion. The launch rattled regional markets, though Japan’s Nikkei index traded flat as the market reopened after a holiday, with investors largely shrugging off the news given the more pressing US data.
Separately, Taiwan condemned planned naval drills involving a Chinese warship and an Indonesian vessel off the island’s east coast, further underscoring the volatile security environment in the Indo-Pacific.
US Inflation Data in Focus
Amid the geopolitical noise, markets are fixated on Wednesday’s US CPI report, due later in the session. According to a Reuters poll, consumer prices are expected to edge up 0.1 per cent in July, following a 0.4 per cent decline in June. Annual inflation is forecast to slow slightly to 3.4 per cent from 3.5 per cent a month earlier.
While the July data will not capture the most recent spike in energy costs, it could still prove instrumental in setting expectations for the Federal Reserve’s policy meeting next month. Money markets currently show an even chance of a rate hike, with traders split on whether the central bank will tighten further or pause to assess the impact of previous increases.
“Everyone’s got their eyes on the CPI report,” said Skye Masters, head of markets research at National Australia Bank. “If you do see the print coming in at zero, I think you’ll obviously see a reasonable rally in Treasuries as the market unwinds expectations for the Fed tightening.” A softer reading could also boost equity markets, while a hotter number might reinforce the case for another hike, pressuring risk assets.
Currency and Bond Market Reactions
The dollar index, which measures the greenback against a basket of major currencies, inched up 0.04 per cent to 99.85, while the euro slipped 0.02 per cent to $1.1538. The Japanese yen weakened 0.03 per cent to 159.31 per dollar, remaining off last week’s high of 155.20 after several suspected rounds of coordinated intervention by Japan and the United States to support the yen.
In bond markets, the yield on Japan’s 5-year government bonds rose to a record high of 2.1 per cent, while the 2-year yield hit a 31-year peak of 1.63 per cent. Markets are increasingly pricing in an early rate hike by the Bank of Japan, as inflation pressures mount domestically.
Equities Cautious, European Futures Dip
Asian equities showed modest gains, with MSCI’s broadest index of Asia-Pacific shares outside Japan rising 0.5 per cent. However, European futures pointed to a weaker open: the pan-region Euro Stoxx 50 futures fell 0.15 per cent, German DAX futures declined 0.12 per cent, and FTSE futures lost 0.25 per cent. US S&P 500 futures were flat, up just 0.03 per cent, reflecting investor caution ahead of the CPI release.
Background: The Iran War and Global Oil
The current escalation traces back to February 28, 2026, when the United States launched a series of airstrikes against Iranian nuclear and military facilities following Tehran’s refusal to comply with IAEA inspection demands. Iran responded with missile attacks on US bases in Iraq and the UAE, drawing the Houthis into the conflict as a proxy force. The war has already disrupted oil shipments through the Red Sea and raised insurance premiums for tankers, with major shipping lines rerouting vessels around the Cape of Good Hope—adding days to transit times and pushing up freight costs.
What to Watch
Traders will be closely monitoring the CPI print at 12:30 GMT. A downside surprise could trigger a relief rally in bonds and equities, while an upside surprise may solidify rate-hike bets and further boost the dollar. Meanwhile, any fresh news from the Middle East—whether a ceasefire breakthrough or another attack—could send oil prices sharply in either direction.
As Rodda put it, “Market sentiment is lukewarm amidst lingering geopolitical risk and as market participants head into US CPI data.” With oil at multi-month highs and gold nearing record territory, the next 24 hours will likely determine whether the risk-off tone intensifies or fades.
