Energy market disruptions and the artificial intelligence investment boom are creating new challenges for central banks, affecting both price and financial stability. Central Bank of Cyprus Governor Christodoulos Patsalides says policymakers need to look beyond headline indicators to understand how these developments are spreading through the economy and financial markets.

Speaking at an MNI Connect video conference on November 11, Patsalides, a member of the European Central Bank’s Governing Council, highlighted two key concerns: persistent energy supply disruptions and the rapid expansion of AI infrastructure. He also warned that the growing complexity of AI financing could have wider implications for European markets.

Energy Shocks Require Closer Monitoring

Patsalides said energy disruptions can affect the economy well beyond the point where supply is interrupted, pushing up costs for households and businesses.

For central banks, the priority is to assess how these shocks spread and whether their effects become embedded in inflation. At its October meeting, the ECB kept interest rates unchanged, with inflation expectations remaining anchored and no significant second-round effects from the energy shock.

According to ECB analysis cited by Patsalides, around 90% of the increase in energy inflation was linked to adverse supply developments associated with the conflict in the Middle East, rather than excessive domestic demand.

However, policymakers cannot assume that every supply shock will have the same impact. Its scale, duration and consequences must be assessed as new data becomes available.

Food And Services Prices Could Signal Wider Inflation

One of the main concerns is whether higher energy costs will feed into other prices. Businesses may pass increased expenses on to consumers, while workers may seek higher wages to compensate for reduced purchasing power.

Recent data showed modest upward pressure on food and services inflation, while core inflation remained unchanged. Although oil prices have fallen substantially in recent weeks, uncertainty persists.

Patsalides stressed the importance of monitoring sector-level price developments, supply chains and inflation expectations. Long-term expectations remain anchored, but short-term expectations have stayed elevated as headline inflation continues to shape public perceptions.

AI Investment Is Creating New Financial Risks

Unlike energy shocks, which can quickly raise costs and constrain production, AI has the potential to increase productivity and support long-term growth. However, its rapid expansion is also creating new financing and financial stability challenges.

AI investment could reach as much as $9 trillion between 2025 and 2032, according to estimates cited by Patsalides. The scale of this expansion is particularly significant as governments face elevated fiscal deficits and technology companies increase capital expenditure, in some cases faster than their cash generation.

The concern is not only how much companies borrow, but also how their financing is structured. Bond issuance, private credit, special purpose vehicles and project-level financing can make it harder for investors and regulators to identify where risks ultimately lie.

Hyperscaler Debt Reaches $570 Billion

Technology and hardware companies reportedly issued around $350 billion in bonds during 2026, roughly twice the amount recorded over the comparable period a year earlier. Outstanding bonds issued by hyperscalers now total approximately $570 billion, including around €39 billion denominated in euros.

European investors are participating in these euro-denominated issues, primarily through a reduced allocation to US Treasury bonds. Growing debt supply, alongside higher credit risk and uncertainty, has contributed to wider spreads in bond and credit default swap markets.

So far, investors have absorbed the additional issuance relatively smoothly. Patsalides also noted limited evidence that AI financing has materially reduced funding available to other sectors. However, this could change if investment projections continue to expand at their current pace.

Central Banks Need Better Analytical Tools

For financial stability authorities, the main risks include concentrated credit exposure, complex financing structures and uncertainty surrounding future investment returns. A large, interconnected financing ecosystem could transmit stress across markets if expectations change or funding conditions tighten.

Patsalides said central banks need to strengthen their ability to understand how economic shocks spread. This means examining energy price changes across sectors and supply chains, while improving transparency around AI financing and investment assumptions.

AI itself could help policymakers process increasingly complex information, but it does not replace the need for sound judgement and rigorous analysis.

As the global economy becomes more complex, central banks must ensure their data and analytical tools keep pace with emerging risks, rather than relying on headline indicators alone.
