Market Developments

Energy

WTI crude traded around $92.30 in Asian hours after extending gains for a third straight day, having also moved above $92.00 earlier in the European session to its highest level since July 23 as Gulf supply risks intensified.

Metals

LME three-month copper rose to a record $14,697 a ton, after also surpassing the previous all-time high above $14,530, supported by strong U.S. demand and supply disruptions in Chile.

Foreign Exchange

The euro held above 1.1600, with EUR/USD trading around 1.1625 to 1.1630 ahead of the ECB decision and U.S. inflation data, while the yen strengthened to a seven-month high before USD/JPY later traded just under 154.00 after a 147-pip round trip.

U.S. Equities

U.S. stock futures weakened during the session, with Dow Jones futures down 0.92% near 52,950, S&P 500 futures down 0.41% below 7,700 and Nasdaq 100 futures down 0.24% below 29,500.

Geopolitics, Trade & Commodities

U.S. Strikes Iranian Oil Tankers as Gulf Tensions Escalate

The United States struck multiple Iranian oil tankers tied to Iran’s Islamic Revolutionary Guard Corps after attempted missile attacks on a U.S. warship, in a sharp escalation of the confrontation in the Gulf. Separate reporting said several tankers were hit near Kharg Island, one of Iran’s main crude export hubs.

The military action immediately intensified concerns over regional energy supply and shipping security. WTI crude extended gains for a third straight day and traded around $92.30 in Asian hours, after earlier rising above $92.00 in the European session to its highest level since July 23.

The broader backdrop for oil markets had already been strained by disrupted shipments through the Strait of Hormuz and attacks on Saudi energy infrastructure. Reports also noted that Saudi Arabia had halted operations at several southern energy facilities after attacks triggered fires and injuries, while the 400,000 barrel-a-day Jazan refinery had already been offline since July.

Iran Threatens Persian Gulf Maritime Exclusion Zone

Iran raised the stakes further after Mohsen Rezaei, secretary of the Supreme National Security Council, warned that Tehran would respond to what it called U.S. economic warfare by imposing a maritime exclusion zone across the Persian Gulf.

The threat added to already elevated concerns over Gulf transit routes at a time when oil and LNG flows through the region remain under pressure. The warning came as markets were already reacting to U.S.-Iran tensions and the risk of further disruption to energy exports and commercial shipping.

Trump Bans Canadian Autos, Dairy and Alcohol

U.S. President Donald Trump banned Canadian autos, dairy and alcohol as Canadian retaliatory tariffs on American goods came into force, opening a new front in North American trade tensions.

The move marked a direct escalation in the dispute between the two countries and added to broader concerns over trade restrictions already affecting global commodity and manufacturing markets.

Copper Hits Record High as U.S. Demand and Chile Disruptions Tighten Supply

Copper prices accelerated to fresh records, with the LME three-month contract reaching an all-time high of $14,697 a ton and also surpassing the previous peak above $14,530 set earlier this year.

The rally was driven by strong U.S. demand linked to planned copper import tariffs by the U.S. Department of Commerce, even though those tariff plans, which had been due by the end of June, have yet to materialise. Rising COMEX inventories were cited as evidence of heavy U.S. buying.

Supply problems in Chile added further support. Chilean copper exports fell to $4.62 billion in August, the lowest level since July 2025, down 14% from July and 3.2% from a year earlier despite average August copper prices being more than 40% above year-earlier levels. Weather-related mine disruptions, severe winter storms and rough seas affecting port operations all contributed to weaker exports from a country that accounts for about a quarter of global mine output.

European Gas Stays Elevated as Gulf LNG Flows Remain Disrupted

European natural gas remained under pressure from supply risks linked to the Gulf. TTF gas was described as supported by low European storage and disrupted LNG flows, with the market retaining a structural geopolitical risk premium.

The key issue for gas markets remained whether a stable political framework could restore Qatari LNG exports on a sustained basis. In the absence of meaningful U.S.-Iran negotiations, stop-start cargo flows were leaving Europe competing for marginal Atlantic supply as winter demand approached. Separate reporting also said European gas prices had reached a three-year high.

Central Banks & Macroeconomics

ECB Decision and U.S. Inflation Data Stay in Focus

Markets headed into the new session focused on the European Central Bank policy decision and upcoming U.S. inflation data, with EUR/USD holding above 1.1600 and trading around 1.1625 to 1.1630.

The ECB was widely expected to deliver its second rate hike of the year, and Christine Lagarde was due to speak later in the day. Survey-based expectations pointed to a strong bias toward another move in September and a terminal rate between 2.50% and 3.00%, with 31% of respondents seeing 2.50% as the peak, 37% seeing 2.75% and 26% seeing 3.00%.

Views on when the next ECB cutting cycle would begin were spread from the second quarter of 2027 to 2028 or later. Concerns about overtightening had also eased since June, with 56% of respondents saying a policy mistake would be the ECB hiking too much, down from 71%, while the share saying the ECB would not hike enough rose to 22%.

BoE's Bailey Says Inflation Risks Remain to the Upside

Bank of England Governor Andrew Bailey said risks to inflation in the UK are to the upside, while stopping short of signalling an imminent rate increase.

Bailey also said he does not think the UK economy is on the verge of a recession, citing slightly stronger recent activity data. His cautious tone weighed on sterling in cross-market trading and contrasted with expectations that the ECB would continue tightening.

Yen Strengthens as Wage Data Reinforce BoJ Hike Expectations

The Japanese yen strengthened to a seven-month high against the U.S. dollar as strong wage data reinforced expectations of a Bank of Japan rate hike. USD/JPY fell to around 153.50 during the European session before later trading just under 154.00 after a 147-pip round trip, leaving the pair roughly 40 pips lower on the day.

The move highlighted how closely markets are linking domestic wage momentum to the outlook for further policy tightening in Japan.

RBA Officials Keep Hawkish Tone as Housing Channel Stays in Focus

Reserve Bank of Australia officials maintained a hawkish tone. Assistant Governor Hunter said the housing market is an important transmission channel for monetary policy and added that the central bank is looking to cool both the housing market and the broader economy.

The policy backdrop helped keep the Australian dollar firm, with AUD/USD supported alongside a softer U.S. dollar during the session.

U.S. Stock Futures Decline as Inflation and Trade Risks Build
