Oil prices rose on Wednesday and were on course for a strong monthly gain as stalled U.S.-Iran talks kept geopolitical risk elevated, while tight fuel markets continued to support prices even as crude supplies from the Middle East recovered.

Brent’s November contract, which expires on Wednesday, was up 57 cents, or 0.6%, at $103.16 a barrel by 0944 GMT. The more-active December contract rose 94 cents to $97.10, while U.S. West Texas Intermediate crude gained 82 cents, or 0.9%, to $90.20.

Brent was heading for a monthly gain of about 14%, its biggest increase since July, while WTI was on course to rise roughly 4%.

The widening gap between the two benchmarks has become another concerning feature of the market. The spread reached its widest level in four months as traders assessed potential U.S. restrictions on diesel exports.

Any restrictions could leave more diesel in the U.S. market, potentially pushing domestic inventories higher and reducing the incentive for refiners to process crude. That would put downward pressure on U.S. crude demand even as international oil markets remain supported by geopolitical and refined-product supply risks.

The conflicting forces highlight the unusual structure of the current oil market. Crude flows are recovering toward normal levels, but refined fuels remain tight, meaning the restoration of oil production and exports has not translated into a complete easing of the broader energy squeeze.

“Recovering crude flows should temper supply-driven price pressures, although persistent product shortages and elevated freight costs are likely to keep the broader energy market tight,” analysts at Japan’s MUFG said.

Saudi Arabia resumed oil tanker loadings from its Red Sea port of Yanbu on Tuesday after restoring operations on the East-West Pipeline, providing another indication that some of the supply disruptions caused by the Middle East conflict are beginning to ease.

Goldman Sachs estimates that Gulf oil exports recovered to 23.3 million barrels per day over the past week, roughly in line with their 2025 average. Exports doubled in September, according to the bank.

JPMorgan estimated that the 10-day average for total oil exports over the past five days stood at 20.5 million barrels per day, equivalent to 89% of 2025 levels.

The recovery is a huge boost because the oil market had been pricing in a substantial disruption to Middle Eastern supply. A sustained return of exports reduces the likelihood of a prolonged physical crude shortage and should eventually place downward pressure on benchmark prices.

But the improvement in crude availability has not fully resolved the fuel-market problem. Diesel and other refined products remain particularly sensitive to disruptions because refining capacity, shipping availability and regional inventories can become constraints even when crude itself is available.

The White House has urged the European Union to draw down emergency diesel inventories in an effort to lower global prices, according to sources.

U.S. President Donald Trump is also considering allowing sales of red-dyed diesel rather than imposing an outright export ban, potentially providing some price relief to consumers ahead of the November midterm elections. The measures underline the political and economic pressure created by elevated fuel prices. Diesel is critical to transportation, agriculture and industrial activity, making sustained shortages more consequential than movements in crude prices alone.

In the United States, crude and gasoline inventories rose last week while distillate stocks fell, according to American Petroleum Institute data cited by market sources. Investors were awaiting official figures from the Energy Information Administration, with analysts surveyed by Reuters expecting crude and product inventories to have declined.

Iran Diplomacy Remains The Market’s Biggest Variable

The prospect of a diplomatic breakthrough between Washington and Tehran has provided intermittent relief to oil markets, but those expectations weakened as talks aimed at ending the conflict stalled.

Qatar said Tuesday that it hoped shuttle diplomacy between Iran and the United States could produce a breakthrough.

Trump, however, denied reports from Axios and CNN that cited U.S. officials as saying he was prepared to offer Iran sanctions relief and release frozen Iranian funds in exchange for “concrete” steps on its nuclear programme.

The conflicting signals leave traders facing two opposing scenarios.

A diplomatic agreement could accelerate the restoration of Iranian oil exports and reduce the geopolitical premium embedded in crude prices. A breakdown in negotiations, by contrast, would leave the market exposed to continued disruption across the region.

That uncertainty is keeping traders focused on both physical supply data and political developments rather than treating the recent recovery in Gulf exports as evidence that the crisis has ended.

Oil Keeps Pressure on Bonds And The Federal Reserve

The oil market is also feeding directly into global bond markets because sustained energy prices threaten to prolong inflation.

U.S. Treasury yields eased on Wednesday after a sharp rise in the previous session, but remained at historically elevated levels. The 30-year Treasury yield fell four basis points to 5.553%, after reaching its highest level since 2002. The 10-year yield was down three basis points at 5.221%, while the two-year yield slipped one basis point to 4.876%.

Higher oil prices complicate the Federal Reserve’s policy outlook because an energy-driven inflation shock can make it harder for policymakers to reduce interest rates.

Markets had recently increased expectations for another 25-basis-point rate increase at the Fed’s October meeting, although those expectations eased on Wednesday after New York Fed President John Williams said there was “no need for urgency, and we have time to gather more information” before the meeting.

The CME FedWatch tool put the probability of an October increase at roughly 44% to 45%, down from around 70% earlier in the week.

Investors were also awaiting the Personal Consumption Expenditures price index, the Fed’s preferred inflation measure. Economists surveyed by Dow Jones expected monthly inflation of 0.3% and an annual increase of 3.7%.

The combination of expensive oil, resilient U.S. economic data and elevated government borrowing costs has therefore created a difficult backdrop for the Fed. Higher energy prices can slow economic activity while simultaneously making inflation more persistent.

Dollar Comes On Board with Strength

The same divergence in monetary-policy expectations has supported the U.S. dollar. The dollar remained close to its highest level of the year against the euro and was heading for its strongest monthly performance against the single currency in 14 months.

The euro was up slightly at around $1.135 but remained near a low reached in the previous session and was on course for a decline of almost 2.3% against the dollar in September. That would give the dollar a third consecutive quarterly advance against the euro.

A stronger U.S. economy and persistent inflation have encouraged markets to price a more restrictive Federal Reserve path than the European Central Bank, where growth remains weaker, and concerns about government debt have increased.

Some of that divergence narrowed on Wednesday. Williams’ comments reduced expectations for an immediate Fed move, while French data showed consumer inflation accelerating more than expected in September.

“I would still regard the current dollar strength as rather fragile, not least because it already appears over-stretched even relative to developments in the euro area-US interest rate differential,” said Thu Lan Nguyen, an FX analyst at Commerzbank.

The euro’s outlook will depend heavily on the relative paths of the Fed and ECB. ECB President Christine Lagarde’s comments earlier in the week were interpreted as pushing back against the prospect of consecutive rate increases, while options markets have increasingly reflected demand for protection against another decline in the euro.

Sterling meanwhile recovered from a three-month low to $1.3265 after revised data showed the British economy grew faster than initially estimated in the second quarter.

Markets are also watching German inflation data and the U.S. PCE report for further clues about the direction of monetary policy.

The Swiss franc was another notable currency mover, with the dollar trading near a 17-month high of 0.8333 francs. The franc has weakened as investors have sought alternative low-yielding funding currencies for carry trades.

The yen has become less attractive for that purpose following Japan’s currency intervention in July, repeated warnings from officials against excessive yen moves and an acceleration in domestic rate increases.

The result is a market increasingly driven by the interaction of three forces: the physical availability of energy, the inflation consequences of the Middle East conflict and the response of central banks to higher prices.

Recovering Gulf crude exports are limiting the risk of an outright oil supply shortage, but they have not yet eliminated tightness in refined products. Until fuel markets loosen materially or U.S.-Iran diplomacy produces a durable reduction in geopolitical risk, oil prices are likely to remain closely linked to inflation and interest-rate expectations across global markets.

Global bonds edged higher on Wednesday but remained on course for their worst month in years as deteriorating government finances, heavy debt issuance and persistent inflation pushed borrowing costs higher, while the seven-month-old US-Israeli war with Iran continued to keep energy prices elevated.

The bond selloff has become one of the most striking developments across global financial markets this quarter. Sovereign yields influence valuations across asset classes, providing the benchmark against which investors price equities, corporate debt, mortgages and other forms of borrowing. Their rapid rise is therefore tightening financial conditions even as stock markets continue to show surprising resilience.

The benchmark 10-year US Treasury yield was 5.209% in early European trading, down 4.6 basis points on the day but still close to its highest level since June 2007. The yield was on track to rise by more than 45 basis points in September, its biggest monthly increase in about two years.

The two-year Treasury yield fell 1.9 basis points to 4.870% after New York Federal Reserve President John Williams pushed back against expectations of an earlier tightening in monetary policy. Even after Wednesday’s decline, the two-year yield was more than 50 basis points higher for the month.

“We have reached yield levels that are becoming genuinely significant,” said Carlo Franchini, head of institutional clients at Milan-based Banca Ifigest. “The temptation to move out of equities could become an issue.”

Franchini said he was not yet taking profits on stocks, however, arguing that equities could remain supported through October if easing tensions around the Strait of Hormuz lead to lower oil prices and relieve some of the pressure on bond yields.

“In my view it is better to stay long,” he said.

Bond Stress Spreads Across Major Markets

The pressure is not confined to the US Treasury market. German and French 10-year government bond yields reached 17-year and 18-year highs this week. German yields were heading for an increase of about 70 basis points for the quarter, while French yields were on track for a roughly 120-basis-point rise.

Japan has experienced a similar move. Its 10-year government bond yield remained near multi-decade highs and was headed for a 38-basis-point increase this quarter.

The synchronized rise in borrowing costs is notable because it reflects more than changing expectations for central-bank policy. Governments are issuing large amounts of debt at a time when investors are demanding greater compensation for holding longer-dated bonds, while higher energy prices are adding another source of inflationary pressure.

The result is a more difficult environment for policymakers. Higher inflation can keep interest rates elevated, while rising debt-servicing costs can make government finances more vulnerable to higher yields.

That dynamic is increasingly visible in markets. The US 10-year yield has moved above 5%, while long-term borrowing costs in Europe and Japan have also risen sharply. The scale of the moves means the bond market is becoming a larger potential constraint on equity valuations and corporate investment.

Yet equity markets have so far largely resisted the pressure.

Stocks Remain Resilient Despite Higher Borrowing Costs

European shares were higher on Wednesday, with the STOXX 600 rising 0.6% by 0812 GMT. The index was still heading for a 1.4% monthly decline but was broadly unchanged for the quarter.

MSCI’s broadest index of Asia-Pacific shares excluding Japan gained 0.3% and remained on course for a 1.1% monthly decline.

Japan’s Nikkei jumped 1.9%, putting it on track for a 0.6% monthly gain, although the index was still set for a 4.7% quarterly decline. South Korea’s Kospi was headed for a 0.3% monthly gain but a 19% quarterly plunge.

US equity futures also pointed to a firmer opening, with Nasdaq futures up 0.2% and S&P 500 futures nearly 0.3% higher.

The resilience makes a difference because higher bond yields normally put pressure on equity valuations by increasing the discount rate applied to future corporate earnings. The effect is significant for technology companies, whose valuations often depend heavily on profits expected further into the future.

“What was surprising to us was the sanguine reaction of the equity market where the growth in nominal GDP was driving earnings optimism,” said Mohammed Apabhai, Citi’s head of Asia-Pacific trading strategy.

“US equity markets are reacting to the rise in bond yields but only outside of the tech space.”

That helps explain why the equity market has remained relatively calm. Strong earnings expectations and continued enthusiasm for artificial intelligence have provided support, while investors appear to be treating the increase in yields partly as a reflection of stronger nominal economic activity rather than an immediate threat to corporate profits.

But that resilience could become harder to maintain if yields remain elevated.

In China, the picture is considerably weaker. The blue-chip CSI 300 rose 0.3% but remained close to a one-year low reached earlier in the week. The index was heading for a 12% quarterly decline, its largest since the height of China’s Covid-19 lockdowns.

Dollar and Oil Reflect The New Macro Pressure

The rise in US yields has also strengthened the dollar. The currency was on course for a monthly gain of roughly 2%, although it slipped 0.1% on Wednesday.

The euro traded just above a 16-month low at $1.1346 and was heading for a 2.3% monthly decline as Europe’s economy faced the combined pressure of higher energy costs and growing political uncertainty.

Sterling rose 0.2% to $1.326 but was set for a 2.1% monthly decline.

The yen moved in the opposite direction, gaining 0.2% to 156.95 per dollar and heading for a 1.7% monthly increase. Investors remain cautious about pushing the currency substantially weaker amid the possibility of coordinated intervention by Tokyo and Washington.

Energy markets remain central to the bond-market story.

US crude was unchanged at $89.41 a barrel, while Brent slipped 0.1% to $102.47. Both benchmarks remained on course for monthly gains as the conflict continued to raise concerns about prolonged supply disruptions.

Those prices are feeding directly into the inflation problem confronting bond investors. If oil remains above $100 for an extended period, central banks could face greater difficulty easing monetary policy even as economic activity slows.

Gold, meanwhile, rose 0.44% to $4,199.28 an ounce, retaining some of its appeal as investors navigate inflation, geopolitical risk and concerns over government finances.

The central tension across markets is becoming clearer: equities are still being supported by earnings, economic growth and the AI investment cycle, while bonds are increasingly demanding a higher price for the risks associated with inflation, debt and fiscal deterioration.

For now, stocks are absorbing the increase in yields. But with the US 10-year yield near 5.2% and borrowing costs rising across Europe and Japan, the bond market is setting a much higher hurdle for the risk assets that have benefited from years of relatively cheap capital.
