AI in Finance: What the World's Central Bankers Discussed

At the ECB forum in Sintra in summer 2026, the world's central banks discussed the adoption of AI in finance. The heads of the largest central banks set aside the usual discussions of inflation and monetary policy to focus on the impact of artificial intelligence on the global economy.

What the Sintra forum is

Every summer, the heads of the planet's most influential central banks, including the US Federal Reserve, the European Central Bank, the Bank of Japan, the Bank of England and several others, gather in the Portuguese town of Sintra, in the hills outside Lisbon.

The format is deliberately closed: it is not a press conference or a public event. Regulators speak about the economy as they see it, without direct pressure from markets and politicians. That is why signals from Sintra are often more accurate than official statements and run ahead of public rhetoric.

For the past several years the forum focused on the inflation crisis of 2021–2023 and the rate-hiking cycle that followed. By 2026, inflation in most countries had returned to target levels, and the familiar agenda left with it. AI took its place.

Why AI replaced inflation

Artificial intelligence became the only theme running through the whole meeting, which is notable in itself. Central banks are among the most conservative institutions in the world. Their traditional toolkit was built over decades: key interest rates, open market operations, macroprudential regulation. Fitting into that system a technological shift that has not yet fully shown up in the statistics is a nontrivial task.

Central banks make forecasts 2–3 years ahead. If AI is changing labor productivity, the structure of employment and price dynamics, and there are already signs that it is, monetary models need to be adjusted. Exactly how remains unclear. The forum discussed both extremes:

• Hopes: productivity growth, disinflationary pressure, new sources of economic growth
• Fears: structural labor market disruption, risks to financial stability, a pace of change outrunning regulatory tools

The meeting's most uncomfortable fact

The defining fact of the forum is not new data and not a consensus, but the lack of one. By the participants' own account, no one in the room can say with confidence how exactly AI will reshape the macroeconomy or on what timeline.

This is a fundamentally different tone from what central banks are used to. Sintra is normally where regulators project coordination and measured judgment. In 2026 it became a venue where the world's most influential practicing economists openly acknowledged the limits of their understanding.

What this means

AI reaching the top of the Sintra agenda signals a qualitative change: the technology has moved from the category of "an interesting future" to "a problem for current planning" for the institutions whose decisions determine monetary policy worldwide.

When central bank heads publicly admit that their forecasting models do not know how to account for AI, it means global monetary policy is entering a period in which familiar benchmarks work less well and new ones have yet to be developed.

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

At the forum, central banks discussed AI as the meeting's main topic, its impact on the global economy and the hopes and fears attached to it, although concrete answers to all the questions were not given.
