Oil prices finished little changed Wednesday as prospects for renewed Russia-Ukraine peace talks offset continuing tanker attacks around the Strait of Hormuz and a larger-than-expected decline in U.S. crude inventories.

MONTREAL (Oil Monster): Oil prices ended almost unchanged Wednesday after another volatile session as traders balanced the possibility of progress toward Russia-Ukraine peace talks against persistent Middle East supply risks and a sharp decline in U.S. crude inventories.
Brent crude futures settled 3 cents higher at $108.82 per barrel.
U.S. West Texas Intermediate crude settled down 67 cents at $97.15 per barrel.
Both benchmarks had traded as much as $2 higher earlier in the session before giving back most of those gains.
Oil prices lost momentum as traders assessed signs that diplomatic efforts surrounding the Russia-Ukraine war could be gaining traction.
The Kremlin said Russian President Vladimir Putin is willing in principle to take part in renewed U.S.-mediated peace talks involving Ukraine as early as November.
The development followed a meeting between Putin and U.S. special envoy Steve Witkoff as Washington continues efforts to revive negotiations.
A potential peace agreement could have important implications for global petroleum markets because the conflict has disrupted Russian refining and constrained exports of diesel and other petroleum products.
Any easing of those disruptions could eventually increase fuel availability and reduce some of the pressure that has supported crude and diesel prices in recent weeks.

The diplomatic picture in the Middle East remains considerably less encouraging.
Iranian Foreign Minister Abbas Araqchi said Wednesday that Iran is prepared to defend itself, while President Masoud Pezeshkian said Tehran cannot be expected to negotiate while facing what Iran describes as U.S. military pressure and blockade measures.
The comments reduced expectations for an immediate breakthrough between Washington and Tehran.
Continued uncertainty over U.S.-Iran relations keeps the Strait of Hormuz and surrounding shipping routes at the center of global energy-market risk.
At least 18 attacks on commercial vessels have been recorded during the past two weeks, according to Kpler data cited by Reuters.
Shipping risks are no longer confined to the narrow Strait of Hormuz.
LSEG analysts warned that attacks have extended into the Gulf of Oman, potentially threatening crude loadings and ship-to-ship transfer operations used to keep Gulf exports moving.
Iran-aligned Houthi forces also claimed responsibility this week for attacks targeting Saudi infrastructure, including an Aramco facility in Yanbu and the Shaybah oilfield.
The continuing incidents mean physical oil flows remain exposed even as producers and traders develop alternative shipping arrangements.
Domestic inventory data provided another source of support for crude prices.
U.S. commercial crude inventories fell by approximately 3.06 million barrels during the week ended October 16, according to the Energy Information Administration.
Stocks declined from approximately 415.6 million barrels to 412.5 million barrels.
The draw was substantially larger than the approximately 820,000-barrel decline analysts had expected in a Reuters survey.
The actual crude draw therefore exceeded the consensus forecast by roughly 2.24 million barrels.
The diesel side of the inventory report told a different story.
U.S. distillate inventories rose by approximately 1.68 million barrels to 104.3 million barrels.
Analysts had expected stocks to decline by about 1.16 million barrels.
That represents a swing of roughly 2.84 million barrels between the expected decline and the actual inventory increase.
The unexpected build offers some modest relief to an exceptionally tight diesel market, although inventories remain closely watched because of continuing global supply disruptions.
Wednesday's EIA report sent two different signals.
The 3.06-million-barrel crude draw was much stronger than expected and points to tighter near-term crude availability.
But the 1.68-million-barrel distillate build moved in the opposite direction, offering some evidence that diesel inventories are beginning to rebuild.
That helps explain why the inventory report did not produce a sustained crude-price rally despite the surprisingly large crude draw.
The Energy Department announced Wednesday that it will offer up to 315,000 barrels of ultra-low-sulfur distillate from the Northeast Home Heating Oil Reserve through an exchange program.
The reserve barrels are stored at facilities in South Portland, Maine; Boston, Massachusetts; and New Haven, Connecticut.
Under the exchange, participating companies must return the same volume of fuel plus an additional premium, allowing the reserve to be replenished ahead of the 2027-28 heating season.
DOE said deliveries are scheduled to be completed by November 13.
The action is intended to ease supply constraints and high heating-oil prices in the U.S. Northeast as winter approaches.

The reserve action comes as governments continue trying to increase diesel availability following supply disruptions linked to both the Middle East conflict and the Russia-Ukraine war.
U.S. Energy Department officials said Tuesday they are working with refiners in the United States and overseas to increase fuel output.
Domestic refiners are already operating at high utilization rates, limiting how quickly additional diesel production can be brought online.
The International Energy Agency is separately accelerating more than 20 million barrels of diesel from previously committed emergency reserves.

Wednesday's trading reflected three major forces pulling crude prices in different directions.
First, the possibility of Russia-Ukraine peace talks could eventually restore more Russian fuel supply and reduce pressure on global diesel markets.
Second, continuing tanker attacks and the absence of meaningful U.S.-Iran dialogue keep a substantial geopolitical risk premium embedded in oil prices.
Third, U.S. inventory data show tighter crude supply but a modest improvement in distillate stocks.
None of those signals is currently strong enough to dominate the market, leaving crude vulnerable to sharp intraday swings as diplomatic and security developments emerge.
Crude inventories are important, but the more consequential signal for the broader energy market may continue to come from diesel.
Distillate supply has become one of the main links between the Russia-Ukraine war, Middle East disruptions, refinery utilization and consumer inflation.
If the unexpected U.S. inventory build develops into a sustained trend while Russian supply improves, diesel prices could begin to ease.
If tanker attacks intensify or Russian fuel remains constrained, Wednesday's build may prove temporary.
For now, the crude market remains caught between improving diplomatic prospects in Europe and deteriorating shipping security in the Middle East.
