AI in Finance: What Central Banks Worldwide Were Discussing

At the ECB forum in Sintra during summer 2026, central banks of the world discussed AI implementation in finance: leaders of the world's largest central banks set aside their usual discussions of inflation and monetary policy, focusing instead on artificial intelligence's impact on the global economy.

What is the Sintra forum

Each summer, leaders of the planet's most influential central banks — the U.S. Federal Reserve, the European Central Bank, the Bank of Japan, the Bank of England, and others — gather in the Portuguese town of Sintra, located in hills below Lisbon.

The format is fundamentally closed: it's neither a press conference nor a public event. Regulators discuss the economy as they see it, without direct pressure from markets and politicians. That's why signals from Sintra often prove more accurate than official statements and precede public rhetoric.

In recent years, the forum focused on the inflation crisis of 2021–2023 and the subsequent rate-hike cycle. By 2026, inflation in most countries had returned to target levels — and the familiar agenda disappeared with it. AI took its place.

Why AI displaced inflation

Artificial intelligence became the sole overarching theme of the meeting — which is remarkable in itself. Central banks rank among the world's most conservative institutions. Their traditional toolkit was developed over decades: key rates, open market operations, macroprudential regulation. Incorporating into this system a technological shift that hasn't yet fully reflected in statistics is a non-trivial task.

Central banks build forecasts 2–3 years ahead. If AI changes labor productivity, employment structure, and price dynamics — and signs of this already exist — monetary models need correction. But how, exactly, remains unclear. The forum discussed both poles:

• Hopes: productivity growth, disinflationary pressure, new sources of economic growth
• Fears: structural labor market disruptions, financial instability risks, changes outpacing regulatory tools

The main uncomfortable fact of the meeting

The organizing fact of the forum — not new data and not consensus, but its absence. By participants' own accounts, no one in the room could confidently answer how exactly AI will reshape macroeconomics and within what timeframes.

This is fundamentally different from the tone central banks have grown accustomed to. Normally Sintra is where regulators demonstrate coordination and prudence. In 2026 it became a platform where the world's most influential practicing economists openly documented the limits of their understanding.

What this means

AI's appearance at the top of the Sintra forum's agenda signals a qualitative shift: the technology has moved from the category of "interesting future" to the category of "current planning problem" for institutions whose decisions shape global monetary policy.

When central bank leaders publicly acknowledge that their predictive models don't know how to account for AI, it means: global monetary policy is entering a period when familiar reference points work less well, and new ones haven't yet been developed.

What did central banks say about implementing AI in the financial system?

At the forum, central banks discussed AI as the main topic of the meeting, its impact on the global economy and related hopes and fears, though no definitive answers to all questions were given.
