Monetary Policy Responses
Adaptations to central bank frameworks, such as interest rate policy, targeted lending facilities, or digital currencies, to manage disruptions to inflation and financial stability.
What it is:
Central banks like the Federal Reserve and the European Central Bank manage the economy by raising or lowering interest rates, making borrowing cheaper to stimulate growth, or more expensive to cool inflation. These decisions depend on stable relationships between employment, prices, and economic output that AI could fundamentally disrupt.
If AI makes businesses dramatically more productive, the economy can grow faster before inflation kicks in; but central banks need to recognize this shift in real time, or they risk setting interest rates too high (stifling growth unnecessarily) or too low (letting inflation build). If AI displaces large numbers of workers while simultaneously boosting output, central banks face an uncomfortable choice: cut rates to help unemployed workers, or hold rates steady because the economy is still growing and prices are rising.
Compounding this, AI-powered pricing algorithms could allow businesses to adjust prices almost instantly in response to changing conditions, meaning economic shocks spread faster across the economy than the slower, stickier price adjustments that central bank models currently assume.
In an extreme scenario, AI-driven productivity gains could push prices persistently downward — a deflationary dynamic that conventional interest rate tools struggle to address once rates hit zero. A BIS working paper modeled these dynamics and found that AI adoption initially pushes prices down, but that general equilibrium forces eventually push inflation upward through demand effects — and that if businesses and consumers anticipate AI's economic boost, inflation rises immediately, requiring central banks to act before the productivity gains fully materialize.

The Impact of Artificial Intelligence on Output and Inflation
April 2024
Uses a model of 20 economic sectors, each with a different level of exposure to AI, to simulate how AI affects growth and inflation. It finds that AI boosts output, consumption, and investment in both the short and long run. Whether AI pushes prices up or down depends on expectations: if people and businesses don't see the productivity gains coming, AI is initially disinflationary, but if they anticipate becoming richer they spend more now, pushing prices up sooner. The paper also finds that how much AI directly affects a given sector is a poor predictor of that sector's long-run growth; what matters more is how that sector connects to others in the economy and how spending patterns shift across sectors.

Implications of Artificial Intelligence for Monetary Policy – A First Conceptual Assessment
January 2025
An early framework from ECB researchers for thinking about how AI might change the job of central banks. On one hand, AI could shift the economic backdrop that central banks respond to — boosting productivity, changing the "right" level of interest rates, or widening inequality. On the other, AI could change how interest rate decisions ripple through the economy — for instance, if AI-driven pricing makes companies adjust prices faster, or if AI-enhanced lending speeds up how credit flows to businesses and households. The authors argue that while the net effects are hard to predict, central banks have the analytical tools to adapt.

Discretion versus Policy Rules in Practice
December 1993
Introduced the "Taylor Rule", a highly influential monetary policy rule linking the central bank's interest rate to deviations of inflation from target and the output gap. Any assessment of how AI disrupts monetary policy ultimately asks whether and how the Taylor Rule's parameters need to change: if AI raises the natural interest rate, compresses the Phillips curve, or makes the output gap harder to measure, the rule's prescriptions shift accordingly.
Real-world precedents:
The Federal Reserve's response to the 1990s productivity boom provides the closest historical analogy: under Alan Greenspan, the Fed recognized that IT-driven productivity gains had raised the economy's speed limit, allowing growth to run faster without inflation — a judgment that kept rates lower than models predicted and supported a prolonged expansion. The question of whether central banks can make a similar call for AI is already an active policy debate, with many economists noting that today's environment of higher baseline inflation, fiscal deficits, and deglobalization makes such patience considerably riskier.
Conversely, Japan's experience with sustained deflation from the 1990s onward illustrates the risks when technological change coincides with structural demand weakness: the Bank of Japan pioneered unconventional monetary tools from the late 1990s onwards — including zero interest rate policy and quantitative easing — but struggled for over two decades to escape deflation. While Japan's deflation was driven primarily by the asset bubble collapse and banking crisis rather than technological change, the episode remains a cautionary precedent for scenarios where AI-driven productivity gains create persistent disinflationary pressure that conventional rate-setting tools cannot overcome.
