Material Change Summary:
Benchmark-tracking prices rose sharply on 2026-09-24 as Houthi launches toward Taif and Yanbu renewed concern about Saudi export infrastructure and Gulf shipping. The observed values were Brent $107.03 per barrel, up 3.83%, and WTI $94.02 per barrel, up 2.02%. These are dated market observations from CFD series that track the benchmarks, not exchange-certified official settlements.

Verified Developments:
1. Brent benchmark-tracking price reached $107.03/bbl on 2026-09-24, up 3.83% from the prior day. WTI benchmark-tracking price reached $94.02/bbl, up 2.02%. Currency/unit: U.S. dollars per barrel. Observation basis: end-of-day dated CFD observations, not official exchange settlement. Geography: global crude market. Source role: market-data provider. Source titles: "Brent Crude Oil" and "Crude Oil." URLs: https://tradingeconomics.com/commodity/brent-crude-oil and https://tradingeconomics.com/commodity/crude-oil . Publication/observation date: 2026-09-24. Confidence: medium-high. Verification: source-linked, internally consistent with the prior day's reported levels.
2. Reporting cited only 10 commodity-vessel Hormuz transits on Wednesday versus a 10-day average of 17, while Houthi launches near Yanbu renewed risk to the Red Sea export corridor. Source role: market-data news synthesis and operational reporting. URL: https://tradingeconomics.com/commodity/brent-crude-oil . Publication date: 2026-09-24. Confidence: medium. Verification: source-linked; not independently audited in this run.

Unvalidated Claims:
- No confirmed physical damage to Yanbu energy infrastructure was established from the intercepted Houthi attack.
- Potential U.S.–Iran phased arrangements remained market expectation, not a completed agreement.

Corrections:
- None. The prior brief's official 2026-09-23 settlements of Brent $103.08 and WTI $92.16 remain the comparison baseline; today's quoted values use a different observation basis and are labeled accordingly.

Operational Significance:
The price move and below-average Hormuz transits show that physical-route risk remains priced into crude even without verified new infrastructure damage. Yanbu's role as an alternative export outlet makes repeated attack attempts operationally important.

Source Gaps:
An accessible exchange-certified official settlement table for both front-month contracts was not available during this review. Vessel-flow counts were not independently verified against a maritime authority dataset.

Recommended Follow-Up:
Confirm the next official exchange settlements, track Hormuz and Bab el-Mandeb transits, monitor Yanbu damage assessments and East–West Pipeline throughput, and watch for verified physical outages.
