The Bank of Japan says the global artificial-intelligence investment boom is beginning to affect monetary conditions through several channels at once, raising questions about how technology investment could influence interest rates and inflation.
Deputy Governor Shinichi Uchida said Monday that widespread AI adoption represents a significant positive demand shock capable of supporting economic activity while placing upward pressure on prices.
At the same time, higher equity valuations associated with AI can loosen financial conditions, while heavy borrowing and bond issuance associated with AI investment can exert upward pressure on long-term interest rates.
Uchida’s comments are notable because they move the AI investment cycle directly into the monetary-policy debate.
Artificial intelligence is usually discussed primarily through productivity. If the technology enables workers and businesses to produce more efficiently, it could increase an economy’s productive capacity.
But the investment required to build AI infrastructure arrives before all those productivity gains are known.
Data centers, processors, power infrastructure and networks require enormous amounts of capital. That spending can stimulate demand today even if the eventual productivity payoff takes years to emerge.
Uchida also raised the possibility that AI could eventually affect the natural rate of interest — the theoretical interest rate consistent with an economy operating without excessive inflation or contraction.
The direction and magnitude remain uncertain.
He also warned of the possibility of financial-market corrections if anticipated AI profits fail to materialize. That represents a conditional risk assessment rather than a prediction that a correction will occur.
For global investors, the significance extends beyond Japan.
If the AI capital-spending boom simultaneously raises asset values, corporate borrowing, investment demand and productivity, central banks may eventually need to reconsider assumptions about neutral interest rates and how much monetary restraint is required to control inflation.
That debate is only beginning.
