Middle East Tensions Threaten Global Chip Supply
Disruptions in the Middle East are creating acute risks for chip fabs, which are highly energy-intensive. A new report highlights dual threats: Taiwan's power grid is under scrutiny, as TSMC is vulnerable to LNG shipping disruptions, and the cost of bromine, essential for DRAM production, is spiking. Social media discussion noted Taiwan only has 11 days of LNG reserves, a critical vulnerability for advanced chip production.
The Strait of Hormuz, a critical chokepoint for global energy, handles about 20% of the world's liquefied natural gas (LNG) and 25% of its seaborne oil trade. Disruptions here directly threaten the energy imports vital for Taiwan's power grid, which is already strained by the massive electricity demands of semiconductor fabrication. Taiwan's grid relies on imported fuel for 97% of its energy needs, with LNG and coal each accounting for roughly 40% of electricity generation. TSMC alone consumed approximately 9% of the island's total power in recent years, a figure that is growing with the adoption of more power-intensive EUV lithography for advanced nodes. This concentrates significant manufacturing risk on the stability of a handful of energy shipping lanes. The Dead Sea, bordered by Israel and Jordan, is one of the world's richest sources of bromine, a key element in the production of flame retardants and other chemicals used in electronics manufacturing. Israel-based ICL Group is a leading global producer, meaning any regional instability can directly impact the supply and cost of materials essential for components like DRAM. Shipping carriers are already imposing war risk surcharges of around $1,500 per container for Middle East routes, and some have suspended bookings altogether. Rerouting vessels around Africa instead of through the Suez Canal adds significant time and fuel costs to journeys between Asia and Europe, tightening effective global shipping capacity and causing knock-on congestion at other major hubs. Compounding these issues, Apple is facing unprecedented competition for advanced foundry capacity at TSMC. The explosive growth in AI has reportedly made Nvidia TSMC's largest customer, shifting the balance of power and putting Apple in a "supply chase mode" for 3-nanometer production. The CHIPS and Science Act is driving billions in domestic investment, including TSMC's new Arizona facilities, to mitigate these risks. However, a critical dependency remains: wafers produced in Arizona for Apple must currently be shipped back to Taiwan for advanced packaging, as the US lacks this at-scale capability onshore. In response to the immediate LNG threat, Taiwan's state-owned utility Taipower has begun stockpiling thermal coal and is preparing to potentially restart decommissioned coal-fired power plants as an emergency backup. This highlights the severity of the energy security risk and the difficult trade-offs being considered to keep the fabs running.
