Will artificial intelligence soon run central banks?

Using this powerful new technology to crunch data, produce forecasts, and detect risks seems like a no-brainer for our economies’ custodians. How they do so is the question.

Will artificial intelligence soon run central banks?

In June, the Bank for International Settlements (BIS)—known as the “Bank of Central Banks”—urged countries to use Artificial Intelligence (AI) to develop analytical tools for their central banks. These tools would, among other things, track real-time data to help predict inflationary trends.

Such monitoring of economic indicators would have been useful in the aftermath of the pandemic or of Russia’s invasion of Ukraine when big central banks failed to grasp just how far and how fast inflation would subsequently rise.

The BIS Annual Report 2024 highlights the impact of new AI applications for central banks, pointing out that the technology is expected to affect the financial system, reshape markets, influence production trends, and impact economic growth. AI is helping firms adjust their prices more rapidly in response to macroeconomic changes, for instance, with implications for inflation dynamics.

AI’s benefits and risks

The financial sector could be one of the biggest beneficiaries of AI if it enhances its efficiency in lending, financial intermediation, insurance, forecasting, asset management, and monitoring liquidity and payments.

AI promises to reduce the cost of time-consuming tasks traditionally done by people, improve customer service, improve fraud detection, and ensure regulatory compliance, such as with the Know Your Customer (KYC) protocols, and with anti-money laundering and counter-terrorist financing systems.

The picture is not all rosy, however. AI could increase risks in the financial sector, such as with biased data or flawed models. If AI tools are trained on out-of-date data, this could result in distorted forecasts and decisions There are also worries about systems' exposure to complex cybercrime.

Gary Gensler, chair of the US Securities and Exchange Commission (SEC) and a professor at the Massachusetts Institute of Technology (MIT), speaks of another issue, warning of the dangers of 'herd behaviour', with algorithms unwittingly provoking or exacerbating financial crises.

Finally, while AI will render some financial jobs redundant, new technology always creates new jobs. Yet the risk with this technology is of concentrating its understanding and operation in the hands of a small number of specialists.

Using AI to manage data

Central banks are the crossroads of the monetary, financial, and banking systems. Custodians of the economy through their monetary policy mandate, they play a key role in maintaining financial stability and regulating and supervising commercial banks and other financial institutions.

Due to the high proportion of central bank tasks that require data-intensive cognitive skills, they are in a privileged position to reap the benefits of AI and Machine Learning tools to support their core functions, such as setting monetary policy, managing the payments system, and collecting and analysing data—their primary resource.

The importance of data has grown with the advent of AI and its growing ability to ingest huge amounts, churning it into information. The question facing central banks is no longer whether to use AI but rather how to use it effectively and responsibly.

Ideally, AI will help to make data (whether structured or unstructured) available in a timely manner and organise it in a way that produces accurate assessments and real-time forecasts that can be easily updated as new data comes in, whether this be on growth, inflation, employment, production, or supply and demand.

Since a single indicator is usually insufficient to accurately track economic activity in real-time, forecasting models often process diverse and complex datasets to develop early warning indicators for potential stress points that could pose systemic risks.

Technology and governance

Beyond the challenge of rapid, real-time data collection, central banks also need to master data governance, specifically the reformatting of data into useful models. Using external models may be more cost-effective, but the reliance on a small number of providers exposes central banks to risk.

Today, data is mainly in the hands of companies who offer related services that are widely used by central banks. The cost of this has increased significantly in recent years, and providers have imposed stricter terms of use.

AI could add efficiency in lending, financial intermediation, insurance, forecasting, asset management, and the monitoring of liquidity and payments

In response, central banks have adopted common procurement systems or collaborations for knowledge sharing. Examples include the BIS Open Tech platform, the Raven project, and the Aurora project. 

The BIS Open Tech platform supports coordination among central banks in developing common standards and sharing data, models, and statistical software, whereas Raven is to enhance cyber resilience, and Aurora is to detect and combat cross-border money laundering and terrorist financing activities.

Other projects (such Ellipse, Gaia, Symbiosis, Neo, Spectrum, and Insight) range from data collection, statistical compilation, payment systems monitoring and supervision, macroeconomic analysis, financial analysis, and monetary policy analysis.

Feeling around in the dark

AI may help central banks better understand the factors that contribute to inflation. It could also analyse financial stability, support macroprudential regulation, improve forecasting, guard against cyberattacks, and manage payments, risks and hedging.

At a recent BIS symposium in Toronto, Bank of Canada Governor Tiff Macklem revealed that they were using AI to forecast inflation, economic activity, demand for banknotes, monitor confidence levels in key sectors of the economy, clean and verify data, and improve the bank's operational efficiency.

He likened working with AI to entering a dark room. "You cautiously feel your way around. This means better information, along with research and analysis on how technology is diffused… and understand how consumers and businesses are behaving and how companies are setting their prices."

He cautioned that it was not easy to strike a balance between progress, innovation, and prudence within a framework of responsibility, and said the bank was adopting principles to guide its use of AI, notably around transparency, and safeguards to question the validity of data when AI is used for content creation or analysis.

Neil Esho, secretary-general of the Basel Committee on Banking Supervision said: "The supervisory processes for judging what is safe and sound, and being able to distinguish between responsible and irresponsible innovation, will undoubtedly improve, but for now we still have some way to go."

Embracing the future

Elizabeth McCaul, a member of the European Banking Supervision Board, thinks advances in AI now allow rapid and accurate analysis of vast amounts of banking data, leading to improved risk detection, adding that the European Central Bank (ECB) has been using AI for three years. 

Its uses include a chatbot for queries on supervisory data and prudential methodologies; translating, analysing, and integrating document content; performing comparisons; understanding complex bank ownership structures; assessing the skill levels of bank board members; drafting reports; ensuring consistency with inspection processes; and locating specific data points.

The question facing central banks is no longer whether to use AI but rather how to use it effectively and responsibly

The ECB's role is primarily to ensure the soundness and stability of the financial institutions it supervises rather than to dictate the models and technologies these banks must adopt. Human expertise remains essential to ensure reliable results.

Exploring the limits

Elsewhere, the Central Bank of Brazil has introduced a prototype to process and classify customer complaints regarding financial institutions, while the Reserve Bank of India has enlisted consultancies McKinsey and Accenture to help it use AI in its supervisory activities, so slowly but surely, central banks are letting the algorithms in.

Yet Hyun Song Shin, chief economist at BIS, cautions policymakers against seeing AI as "something magical" rather than an innovation to help find the needle in the haystack and identify vulnerabilities in financial systems. 

Cecilia Skingsley of the BIS Innovation Hub adds that AI should not replace humans in certain decision-making areas, such as setting prices and interest rates, since having an entirely AI-driven process carries significant risks that could be destructive.

Data governance remains among the most important challenges for central banks and AI, not least since the European Union adopted its first AI law. For all the promise it holds, central banks must first and foremost maintain confidentiality, ensure reliability, and manage new operational risks. Liability arising from the use of AI will, therefore, need to be carefully considered.
