The AI Boom and the Price of Permission

Summary

• The AI investment boom drives demand for semiconductor exporters, equipment manufacturers, and energy suppliers globally.
• Continued expansion depends on political consent in addition to finance and technology.
• Resistance to data centre construction acts as a modest immediate constraint, though delays could spread through supply chains.
• The United States remains central to the investment cycle, while Asian producers supply chips and European and Japanese manufacturers provide equipment.
• Pension funds, insurers, and other investors share financial exposure through global equity portfolios.
• Rising equity valuations improve financing conditions, creating a loop where spending generates revenues that sustain further investment.
• Semiconductors account for roughly two-fifths of South Korean exports, double their share four years ago.
• Taiwan holds substantial exposure to strong technology demand, increasing dependence on a small group of customers.
• The supply chain extends beyond chips to include turbines, grid equipment, copper, steel, and concrete for data centres.
• A slowdown need not involve a collapse in spending, but suppliers can face weaker orders if investment ceases to accelerate.
• Since late 2022, additional investment in the US has been closely matched by rising profits in supplying sectors.
• Tobin's Q for US equities stands at roughly twice its long-run average, suggesting a sustained market reversal could hinder financing.
• US equity weight in global portfolios exposes institutions and households worldwide to the same earnings expectations.
• Political resistance through local opposition and campaigns can delay physical investment before effects appear in market prices.
• Longer planning timelines and more costly agreements could reduce the pace of expansion even without widespread prohibitions.
• Today's boom has a firmer earnings foundation than the late-1990s technology surge, yet depreciation costs will increasingly weigh on reported profits.
• The central risk is a mismatch between the timing of AI benefits and expectations embedded in current investment plans.
• Slower spending, weaker supplier earnings, and lower equity valuations could reinforce one another to transmit adjustments across borders.
• Political consent now joins capital, computing power, and electricity as a condition shaping the transition from infrastructure spending to productivity gains.
