Bank of Japan warns AI boom could keep inflation elevated in Japan

The Bank of Japan (BOJ) has cautioned that the rapid global expansion of artificial intelligence investment could generate sustained inflationary pressure in Japan, suggesting that the country's central bank is increasingly attentive to new structural risks that may influence future monetary policy.

In an assessment released on Monday, the BOJ noted that surging worldwide demand linked to AI technologies could have a more persistent impact on prices than previously anticipated, potentially strengthening the argument for an interest rate increase if inflationary pressures continue to build.

AI investment may outweigh productivity gains in the short term

While artificial intelligence is widely expected to improve productivity over time, the BOJ believes the immediate economic effects could be more inflationary than disinflationary.

According to the central bank, businesses and workers will gradually adapt to AI-driven technologies, eventually improving efficiency and helping to moderate prices over the medium and long term. However, during the current phase of accelerated investment, the sharp increase in demand for AI-related infrastructure, equipment and services could temporarily outpace those productivity benefits.

As a result, inflationary pressures generated by the global AI boom may prove more persistent than initially expected.

Spillover effects could shape Japan's inflation outlook

The BOJ also highlighted the potential for international AI investment to affect Japan through global supply chains and stronger worldwide demand for advanced technologies and industrial inputs.

These spillover effects, the central bank said, may continue to influence domestic prices even if inflationary pressures originating from other sectors begin to ease.

The analysis reflects growing attention among policymakers to structural changes in the global economy, where large-scale investment in artificial intelligence is increasingly reshaping production, trade and capital allocation.

Implications for monetary policy

The BOJ's latest assessment underscores its concern that inflation risks remain tilted to the upside despite expectations that AI will eventually enhance productivity.

Should AI-driven demand continue to support higher prices, policymakers could find additional justification for tightening monetary policy sooner than previously anticipated.

The central bank also indicated that, overall, Japanese households are expected to benefit from higher interest rates, suggesting confidence that a gradual normalization of monetary policy could support broader economic stability while addressing persistent inflationary pressures.
