Do Banks Dream of Sovereign AI? The Future of Algorithmic Monetary Policy

By Dr. Adrian C. Halloway, Nobel Laureate in Economics and specialist in Algorithmic Finance

Monetary policy has always been in human hands: central bank presidents, expert committees, and economists balancing inflation, employment, and financial stability. But by 2040, that role may be entrusted to an autonomous algorithm.

The concept of the “Algorithmic Governor” —an artificial intelligence capable of directing global monetary policy— is moving from science fiction to central bank research agendas. The question is no longer whether it is possible, but what consequences it would bring.

Artificial Intelligence and Central Banks: an Inevitable Union?

The appeal of artificial intelligence in monetary policy rests on three undeniable advantages:

1. Surgical speed: while a committee takes weeks to deliberate, an AI could react in milliseconds to a financial shock.
2. Political neutrality: an algorithm is immune to elections, lobbying, and partisan pressure.
3. Predictive accuracy: machine learning models already outperform traditional indicators in forecasting recessions and volatility.

In a digitalized, hyperconnected global market, delegating decisions to AI seems a logical step toward stability.

The Dark Side of Algorithmic Control

The benefits, however, come with new and profound risks:

• Unprecedented crises: AI learns from past data, but not from futures it has never seen. How would it respond to a digital pandemic or a global energy blackout?
• Opaque models: how could a central bank justify a rate hike if not even its engineers understand the inner logic of the neural network?
• Democratic deficit: monetary decisions shape mortgages, pensions, and wages. What legitimacy would a system have if it was never chosen by the citizens?

2040: A Plausible Scenario for Algorithmic Monetary Policy

Picture the European Central Bank in 2040: a hybrid system where:

• Humans set the strategic framework.
• The Algorithmic Governor adjusts interest rates in real time, processing millions of variables —from lithium prices in Chile to consumer spending patterns in Berlin.

Monetary policy would no longer be a monthly ritual but a continuous flow of algorithmic micro-decisions. A system more stable than ever, but also less human.

The Ethical and Economic Dilemma

Money is more than a medium of exchange: it is a social contract built on trust. Handing it over to an AI would mean redefining that contract.

The real dilemma is not whether AI can govern money —because we already know it can— but whether society is willing to accept that the most consequential economic decisions will be made by a non-human intelligence.

Conclusion: Human or Algorithmic Monetary Policy?

Algorithmic monetary policy will be one of the defining debates of the 21st century. By 2040, the global financial order may no longer be determined by Jerome Powell or Christine Lagarde, but by an Algorithmic Governor hosted on a quantum server.

The ultimate question then will be: will money still be ours, or will it belong to an intelligence we never voted for?
