Pronóstico: WTI Crude Oil (WTI) Up or Down on June 26?

Platform comparison

Market context

The underlying event is whether WTI Crude Oil futures closed higher on Friday, 26 June 2026, than on the preceding trading day. The market settled sharply lower that Friday, with prices hitting a fresh four-month low as global supplies surged. An acceleration of oil tankers through the Persian Gulf and the Strait of Hormuz added millions of barrels to the market, undercutting prices [1]. Saudi ships are also heading to Ras Tanura, signalling a restart of exports from the region for the first time since March [1].

Historically, such supply-driven drops rarely reverse within a single day. When tanker traffic spikes and exports recover to pre-war levels—now at 75%—prices tend to remain depressed for several sessions [1]. The 26 June close of $69.21 was notably below the 25 June close of $71.92, confirming a downward move [2]. In comparable cases where Persian Gulf exports rebounded sharply, the probability of an immediate upward close on the following day has been negligible, aligning with the current 0% crowd-implied probability for "Up".

Traders should monitor daily tanker traffic data from the Hormuz and Persian Gulf, as well as any announcements on Saudi export volumes. A Bloomberg report confirmed 13 million barrels left the region over three days through Wednesday, reinforcing the supply pressure [1]. Additionally, watch for any unexpected disruptions to tanker flows or geopolitical shifts that could alter export rates. Until such catalysts emerge, the supply surge suggests continued downward pressure, making an upward close unlikely.
