Central banks meet AI twice: as a shock to policy and as a tool for models

AI as policy shock

A Bank of Finland speech this week made AI Europe's problem to solve. Europe's decisive issue regarding AI, the speech argued, is widespread adoption across firms and industries — the point is not who invents the technology but who deploys it. That framing landed alongside a grim macro backdrop: the euro area economy is expected to grow by slightly less than one per cent this year, even though the ECB revised its growth forecast for the euro area upwards in September. m:…8313

Inflation, meanwhile, is not cooperating. Euro area inflation remains above target, mostly due to higher energy prices, which puts the central bank in the familiar position of trying to keep a temporary energy shock from embedding itself in wages and expectations. AI is offered as the productivity escape hatch; energy prices are the inflation trap. m:…8313

AI as the central banker's own tool

The Bank of Greece, meanwhile, is putting AI inside the machine. The bank published a research paper titled 'From equations to prompts: integrating LLMs into a hybrid macroeconomic ABM' — work that explores the integration of Large Language Models into macroeconomic Agent-Based Models. Households as equations is the old way; households as agents you can prompt is the experiment. m:…8739

This is reasoning, not a finding in the paper: if AI adoption is increasingly the force shaping the economy, then models that can read and generate language have an obvious appeal to central banks that need to simulate behavior rather than solve for equilibrium. The Greeks are testing whether prompts can do what equations used to. m:…8739

The mandate is widening too

A speech at the Bank for International Settlements argued that financial health is not just a social concern but has a two-way relationship with central bank mandates. The speaker put the proposition plainly: "My central proposition is simple: the relationship between financial health and central banks' core mandates runs in both directions." m:…0502

The practical case runs through transmission: household financial health influences the transmission of monetary policy, and subjective indicators of financial health may provide early warning signals for financial vulnerabilities before they show up in arrears data. The same speech offered a crisp line on crypto for the financially underserved: "The volatility in crypto markets, the prevalence of fraud and the absence of protection similar to that for traditional financial products, such as deposit insurance, expose retail customers to substantial losses." m:…0502

What it adds up to

This is reasoning: two different jobs are being described in the same week. One is AI as a force the economy must absorb — the Bank of Finland's adoption argument, set against sub-one-per-cent growth and above-target inflation. The other is AI as an instrument the central bank itself picks up — the Bank of Greece's prompts-in-the-model paper. The BIS speech adds a third strand: maybe the dashboard needs new gauges, like household financial health, not just new models. m:…8313

This is reasoning: for bankers, the read-through is that policy frameworks are in flux on both sides of the screen — the shock the economy delivers and the simulator the central bank runs. Nobody announced a policy change this week. But the vocabulary is changing, and vocabulary at central banks tends to precede the models, which precede the decisions. m:…0502
