The Bank of Japan sees AI's spending shock before its productivity payoff

A central banker gave a more useful account of AI's economic effects today than either 'boom' or 'bubble.' In remarks at a research meeting, the Bank of Japan's deputy governor described AI investment as a positive demand shock already pushing activity and prices upward. He also described a possible later supply-side gain from productivity, an asset-price lift that can ease financial conditions, AI-company bond issuance that can tighten long-term rates, and potential restructuring of cognitive work. These forces point in different directions and arrive on different schedules. The speech says the size and timing are not yet clear. It tentatively sees demand arriving first and warns of a correction if profits do not follow. None of this is a Bank of Japan interest-rate decision or a forecast of a recession. The bank also sees AI and big data helping researchers handle larger and more varied datasets, while warning that alternative data may be less useful in some economic conditions. That distinction matters because better dashboards do not eliminate the uncertainty in what the economy is doing. The most important human question is who can adapt if the productivity gains eventually arrive unevenly. Workers whose cognitive skills lose value and firms supplying the buildout will not share one average experience. Watch wage, employment, price and investment evidence together, not merely model benchmarks or stock prices.
