The war around Iran is producing an unexpected winner inside the metals chain: Chinese aluminum smelters. The disruption of shipping through the Strait of Hormuz has not only squeezed Middle Eastern aluminum producers, it has also stranded or redirected raw materials that would normally feed them.

More alumina, the refined intermediate made from bauxite and used to produce primary aluminum, is now being redirected toward China, while vessels carrying bauxite and alumina are diverting away from Gulf destinations because Hormuz has become largely unusable for normal traffic. This matters because the Middle East accounts for about 9% of global aluminum output and depends heavily on imported alumina and bauxite to keep its smelters running.

The collapse in Gulf oil exports over the past two weeks shows that the economic consequences of the U.S.-Iran war are no longer hypothetical or confined to futures markets. Crude, condensate and refined-fuel exports from eight Middle Eastern producers averaged 9.71 million barrels a day in the week to March 15, down 61% from February.

Before the war, those same eight countries accounted for roughly 36% of global seaborne oil exports. This is not just another geopolitical premium in oil prices. It is a historically large physical supply disruption already reshaping global trade flows.

Britain is preparing to harden its steel trade defenses in what looks like a significant shift toward a more openly protectionist industrial policy. The government is expected to cut import quotas for many steel products and raise tariffs on shipments outside those limits to 50%, roughly bringing the UK into line with the European Union and the United States.

The move would form part of a broader steel strategy expected shortly from the government, which has already made clear that it sees the survival of domestic steelmaking as a strategic priority rather than simply a matter of market efficiency.

Guinea is weighing a move that could ripple far beyond West Africa: the possible introduction of bauxite export quotas at a moment when prices are weakening, freight costs are rising and the global aluminum supply chain is already more politically exposed than it used to be.

The government is assessing quotas for individual mining projects, potentially as soon as this month, with discussions apparently focused on larger producers. No final decision has been taken, but the fact that quotas are even under consideration is significant because Guinea now accounts for more than 40% of global bauxite supply and has become the single most important external source of ore for China’s aluminum sector. Guinea’s exports rose 25% in 2025, with more than 70% going to China.

China entered 2026 still adding heavily to its crude oil inventories, using a period of relatively cheap imports and strong supply availability to build buffers even as domestic fuel demand remained too weak to absorb all of the barrels arriving at its ports.

China had a crude surplus of about 1.24 million barrels a day in January and February, based on the gap between total available crude from imports and domestic production and the amount processed by refineries. That was lower than the record 2.67 million barrels a day estimated for December, but still above the average surplus for 2025, indicating that China was continuing a stockpiling strategy that had already been underway for months.

The postponement of Donald Trump’s planned summit in Beijing with Xi Jinping does not appear to signal a collapse in U.S.-China ties, but it does reveal how quickly the wider geopolitical environment is beginning to intrude on even the most carefully managed parts of the relationship. Trump asked to delay the trip, originally planned for the end of March, because the war with Iran has disrupted his foreign-policy agenda and made it difficult to proceed with a major leaders’ meeting on schedule.

The delay is unlikely to produce a fundamental rupture, and Chinese officials have indicated that communication over the timing continues. Still, the decision matters because it interrupts a moment when both sides had just concluded trade talks in Paris aimed at preparing the ground for a presidential summit.

Asia’s power sector is being pushed back toward coal by a new geopolitical shock that is exposing the fragility of the region’s gas strategy. Utilities across South Asia, Southeast Asia, Japan and South Korea are raising coal-fired generation as the Iran conflict disrupts LNG flows through the Strait of Hormuz, sends spot LNG prices to three-year highs and forces governments to prioritize energy security over fuel-switching ambitions.

Bangladesh is increasing coal generation and coal-fired power imports, the Philippines is cutting LNG-fired output while relying more heavily on coal, Thailand is running its largest coal plant harder to conserve gas, South Korea is preparing to lift limits on coal generation while raising nuclear output, and Japan’s JERA says it will keep coal plants running at high utilization.

Japan and the United States are preparing to use this week’s leaders’ summit to push their economic relationship further into the realm of strategic resource security. The two sides are expected to announce cooperation on the joint development of rare earths, lithium and copper, with Japanese companies including Mitsubishi Materials and Mitsui involved in projects such as a rare earth refining operation in Indiana and a lithium mine in North Carolina.

The immediate significance is that critical minerals are no longer being treated as a narrow commercial issue. They are being elevated to the top tier of alliance management, alongside defense, semiconductors and energy security.
