Market Developments

Energy

WTI crude traded around $90.40 in Asian hours, near $91.15 on Monday and above $92.00 in early European trading on Tuesday, reaching its highest level since late July as Middle East supply risks remained elevated. Crude had added 1.6% on Monday and risen roughly $10 from the $81 area in nine sessions.

Foreign Exchange

USD/JPY fell into the mid-153.00s and the yen reached a seven-month high as stronger Japanese data and rising expectations of Bank of Japan tightening drove broad yen strength. EUR/USD held around 1.1625 and stayed above 1.1600 ahead of this week’s ECB decision and key U.S. inflation data.

U.S. Equities

U.S. equity futures weakened during European hours on Tuesday, with Dow Jones futures down 0.92% near 52,950, S&P 500 futures lower by 0.41% below 7,700 and Nasdaq 100 futures down 0.24% below 29,500.

Metals

Copper extended its rally to a record $14,697 per ton on the London Metal Exchange as tariff concerns and supply constraints tightened the market backdrop.

Geopolitics, Energy & Commodities

Middle East Tensions Keep Oil Supply Risks in Focus

Oil markets remained dominated by Middle East disruption risks during the reporting window. Saudi Arabia halted operations at several southern energy facilities after attacks triggered fires and caused injuries, while shipments through the Strait of Hormuz remained constrained by the U.S.-Iran conflict. The Houthis have also threatened to blockade Saudi oil flows, adding to concerns over simultaneous losses across key regional export routes.

WTI traded around $90.40 in Asian hours, near $91.15 on Monday and above $92.00 in early European trading on Tuesday, its highest level since July 23-24. Separate reporting in the window noted crude had added 1.6% on Monday and climbed roughly $10 from the $81 area in nine sessions. Commentary in the reporting period also highlighted that the Jazan refinery, with capacity of 400,000 barrels a day, had already been offline since July.

The broader supply picture remained uneven. One report argued that global crude production itself had not yet materially stopped, but distillate markets were tighter, while another said the market was increasingly braced for Brent to move sustainably above $100 a barrel as regional supply risks intensified.

Iran Threatens Persian Gulf Maritime Exclusion Zone

Iran raised the geopolitical stakes 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 statement added to already elevated concerns over shipping security and energy flows through the Gulf, where markets are closely watching the impact of the U.S.-Iran confrontation on crude and LNG transport routes.

European Gas Holds Risk Premium as Gulf LNG Flows Stay Disrupted

European natural gas prices remained supported by low storage levels and disrupted Gulf LNG flows. Rabobank said the key issue for gas markets was not occasional vessel passage through Hormuz, but whether negotiations could restore Qatari LNG exports on a sustained basis.

The bank said the absence of meaningful U.S.-Iran negotiations meant there was no meaningful surge in LNG flows out of the Gulf, leaving Europe to compete for marginal Atlantic supply as winter demand approaches. Rabobank said temporary progress on shipping corridors could trigger short-lived sell-offs, but only a credible political agreement restoring shipping confidence would remove the structural risk premium from TTF.

Its base case put 2026 fourth-quarter TTF at an average of €60/MWh and 2027 at €42/MWh, while an infrastructure-damage scenario would make a €50-60/MWh range more likely through much of next year.

Copper Reaches Record High on Tariffs and Supply Concerns

Copper prices accelerated their rally and reached a record $14,697 per ton on the London Metal Exchange on Tuesday. The move reflected a combination of U.S. tariff pressure and ongoing supply concerns, extending the sharp advance in industrial metals during the week.

Macroeconomics & Central Banks

Yen Strengthens as Markets Price Faster Bank of Japan Tightening

The yen strengthened to a seven-month high against the dollar, with USD/JPY falling into the mid-153.00s as expectations of Bank of Japan tightening gathered pace. Reporting in the window linked the move to stronger Japanese wage and GDP data, capital repatriation, the unwinding of yen-funded carry trades and a suspected bout of intervention.

One report said overnight index swaps were implying around 75 basis points of cumulative BoJ hikes by April 2027 and assigning meaningful odds to a move at the 18 September meeting. The same report said recent catalysts for more hawkish expectations included comments tied to BoJ Governor Kazuo Ueda’s meeting with U.S. Treasury Secretary Bessent and remarks from BoJ board member Takata that outsized rate hikes above 0.25% and back-to-back increases were possibilities.

ECB Rate Decision Looms After Stronger Eurozone Growth Revision

Attention in Europe remained fixed on Thursday’s European Central Bank decision, with multiple reports in the window pointing to a widely expected 25 basis-point rate increase that would take the policy rate to 2.50%. EUR/USD held around 1.1625 and above 1.1600 as markets weighed the policy outlook against upcoming U.S. inflation data.

The macro backdrop firmed after Eurozone second-quarter growth was revised up to 0.6% from a 0.4% consensus, while the Sentix investor survey rose to 5.1 from 0.9. Commentary in the reporting window also noted that the ECB’s September projections were not expected to show material changes to growth and inflation forecasts, with improving leading indicators and softer core inflation offset by higher energy prices.

Inflation remained central to the policy debate. One report said euro area headline inflation rose 0.4 percentage point to 3.3% year on year in the August flash reading, its strongest level since late 2023. Another noted Brent crude and natural gas prices were 8% and 44% higher, respectively, than at the time of the June ECB meeting. Several reports said markets were also pricing ECB rates at 3.00% over the next 12 months.

U.S. Inflation Data Seen as Key to September Fed Decision

U.S. inflation data remained the main near-term policy focus after strong August nonfarm payrolls revived expectations for a September Federal Reserve rate increase. Brown Brothers Harriman said the September 16 decision hinged on Friday’s August CPI report, while Thursday’s PPI release would serve as a lead-in.

The same report said New York Fed President John Williams and Fed Governor Christopher Waller had earlier highlighted an encouraging inflation trend, while Fed Chair Kevin Warsh said at Jackson Hole that better summer PCE and CPI readings did not yet show that underlying trends had meaningfully improved. It also noted that the August pick-up in the ISM Prices Paid index pointed to upside inflation risks, while slower average hourly earnings growth remained an important disinflationary force.

Bank of Canada Tone Turns More Hawkish on Inflation Risks

Bank of Canada commentary in the reporting window pointed to a more hawkish tone after last week’s policy decision, with greater emphasis on upside inflation risks and less concern over trade uncertainty. The overnight rate remained at 2.25%.

The report said oil prices had largely normalized after moving above $100 a barrel in response to the U.S.-Iran conflict, but that the shock still mattered for the inflation outlook with headline CPI near the top of the Bank’s 1-3% target range. It also said trade tensions had escalated with Section 338 tariffs introduced on August 22.

RBA’s Hunter Says Housing Is a Key Monetary-Policy Transmission Channel

Reserve Bank of Australia Assistant Governor Hunter said the housing market is an important transmission mechanism for monetary policy and said the central bank is looking to cool conditions in both housing and the broader economy.

Market Sentiment

U.S. Stock Futures Fall as Inflation and Trade Risks Weigh

U.S. equity futures moved lower during European trading on Tuesday as investors tracked inflation risks, trade tensions and higher energy prices. Dow Jones futures fell 0.92% to around 52,950, S&P 500 futures declined 0.41% to below 7,700 and Nasdaq 100 futures lost 0.24% to below 29,500.
