Global Supply Shocks Hit Metals, Oil; Gulf Lease Sale Advances

Aluminum prices hit a seven-week high in London on Wednesday after a natural gas disruption forced a major refinery to slash output, according to OilPrice.com. Norwegian producer Norsk Hydro cut production by 50% at its Alunorte alumina refinery in Brazil, one of the world's largest. The incident highlights the energy-intensive nature of refining and comes as London Metal Exchange aluminum inventories dropped to 250,000 tons, the lowest level since November 1990.

Separately, Ukrainian forces have suspended drone attacks on oil tankers at Russia's Novorossiysk port following a request from U.S. Vice-President JD Vance, the Financial Times reported. The attacks had twice shut down the Caspian Pipeline Consortium (CPC), which transports crude from major Kazakh fields like Tengiz and Kashagan. The pipeline is a critical conduit for Kazakh oil, handled by international firms including Chevron, to reach European markets as an alternative to Russian supplies. The disruption caused Kazakh oil production to fall to about 1 million barrels per day at the end of July, down from over 2 million bpd in June.

In the Gulf of Mexico, the Trump administration is holding a major lease sale on Wednesday, August 12, offering oil and gas leases across more than 81 million acres. This is the third of 30 Gulf lease sales mandated under a 2025 law. The sale comes as Brent crude trades above $89 per barrel, driven to four-year highs by supply disruptions from the U.S.-Israeli war with Iran that began in February. Despite the vast area offered, pre-sale documents show only 12 companies submitted 69 bids covering roughly 330,000 acres, or about 0.4% of the total.

The global aluminum deficit, exacerbated by the Alunorte outage, could top 900,000 tons this year if trade through the Strait of Hormuz remains disrupted, Norsk Hydro warned. Concurrently, copper is trading above $14,000 per ton in London as U.S. stockpiling ahead of expected tariffs tightens global supply. Analysts note that soaring prices for these key industrial metals will increase costs for electrification and decarbonization projects.

For Bakken operators, these global events underscore interconnected supply risks. The suspension of attacks on the CPC pipeline may help stabilize a key alternative crude stream for global markets, while sustained high oil prices continue to support the economic environment for shale production. The Gulf lease sale represents long-term federal policy support for domestic production, though offshore projects do not address immediate supply needs.
