### Catalyst Analysis: Geopolitical De-escalation Hopes Oil prices softened at the start of the week as market participants anticipated potential diplomatic breakthroughs surrounding the US-Iran situation during UN meetings. KCM Trade chief market analyst Tim Waterer noted in a Reuters report on Monday, September 21, 2026, that a degree of risk premium is being stripped from valuations on hopes of a diplomatic path to de-escalate tensions, though the durability of those hopes remains uncertain.

The downside move materialized despite severe escalations over the weekend, including fresh economic warnings between Washington and Tehran and Houthi strikes targeting Saudi Arabia, including Riyadh. Concurrently, Saudi Arabia managed to redirect and scale its crude export flows via the Strait of Hormuz to 2.9 million barrels daily over the past week, up sharply from 700,000 barrels daily in August, according to data cited by JP Morgan.
