Brent crude edged up to US$108.82 a barrel and US West Texas Intermediate (WTI) fell to US$97.15 on Wednesday (October 21, 2026), as traders weighed possible Russia–Ukraine peace talks against lower US oil stocks and the absence of US–Iran dialogue. Both benchmarks surrendered earlier gains of more than US$2 a barrel.
Brent’s October 21 settlement was three US cents, or 0.03%, higher, while WTI ended 67 US cents, or 0.7%, lower. Brent had traded close to a five-month high earlier in the session.
Brent reached a five-month high and WTI a six-month peak during the October 20 session before retreating following discussions about mediation at a meeting in Tehran between Iranian President Masoud Pezeshkian and Pakistan’s army chief.
US crude inventories declined by 3.06 million barrels to 412.5 million barrels in the week ending October 16, according to figures released by the US Energy Information Administration (EIA) on October 21. Analysts surveyed by Reuters had expected a much smaller reduction of 820,000 barrels.
US distillate inventories, which include diesel and heating oil, moved in the opposite direction. EIA figures showed an increase of 1.68 million barrels to 104.3 million barrels in the week ending October 16, against expectations for a fall of 1.16 million barrels.

Dennis Kissler, senior vice-president of trading at BOK Financial, said apparent progress in US–Russia discussions over a possible Ukraine settlement had been weighing on crude prices. Kissler said a peace agreement “could unlock the tight global diesel supplies”, easing a shortage that had helped drive oil prices higher in recent weeks.
Iranian President Masoud Pezeshkian told state media on October 21 that Washington could not expect dialogue while blockading and threatening Iran. Iranian Foreign Minister Abbas Araqchi separately told the Financial Times that Iran was fully prepared to defend itself.

BOK Financial’s Kissler wrote in a client note earlier on October 21 that crude futures were moving between gains and losses but remained well below their overnight highs. Kissler pointed to apparently continuing attacks in the Strait of Hormuz, with at least two more ships struck overnight.
