European Central Bank (ECB) chief economist Philip Lane has identified rising investment in artificial intelligence as a significant factor influencing global bond yields, pointing to increased long-term borrowing by U.S. companies financing AI-related projects.
In an interview with Italian news agency ANSA published Tuesday, Lane described artificial intelligence as potentially the most important global economic issue, noting that substantial investment in the technology is contributing to higher demand for long-term financing.
According to Lane, AI-related activity is also supporting international trade this year, particularly in semiconductor chips and other materials used in the technology’s development. He noted that Europe participates in the AI supply chain “to some extent.”
Lane said the expansion of AI investment in the United States is one of the factors contributing to rising long-term bond yields. He explained that higher borrowing costs, particularly when driven by developments outside Europe, can slow economic activity in the eurozone and reduce inflationary pressures.
The ECB will consider these effects alongside its broader assessment of inflation and economic risks when determining interest rate policy, he said.
Energy Prices and Inflation Remain Central to ECB Policy
Turning to energy markets, Lane said higher prices have not yet produced substantial secondary inflationary effects across the eurozone.
“We have not seen so far very strong second-round effects. We continue to look at them,” he said.
Lane indicated that uncertainty remains over how extensively higher energy costs will affect prices throughout the economy. He also cautioned that it is “too simplistic” to classify current economic conditions as corresponding directly to either the ECB’s baseline or adverse scenario.
According to Lane, the energy price shock has been the principal factor behind the ECB’s recent interest rate increases.
He said the eurozone economy remained resilient during the summer, partly supported by a temporary decline in energy prices following an understanding between Iran and the United States.
However, Lane noted that renewed increases in energy prices and continuing uncertainty surrounding the conflict have raised questions about whether that support will persist.
Fiscal Support and Wage Developments
Lane also discussed changes in the fiscal environment, noting that economic support this year includes Germany’s infrastructure and defence spending programme and the final year of the European Union’s Next Generation recovery fund.
These measures will affect the fiscal outlook differently in subsequent years, he said.
Addressing economic conditions in Italy, where inflation was recently reported at 4.1%, Lane said assistance for lower-income households should be targeted rather than delivered through broad fiscal expansion.
He stated that widespread increases in government spending “is not going to help inflation return to 2 per cent in a timely manner.”
The ECB’s September projections indicate that Italian wage growth is expected to exceed inflation in both 2027 and 2028.
Lane cautioned, however, that excessively rapid wage increases could affect Italy’s ability to attract foreign investment and encourage employment growth.
Lane Highlights Borrowing Costs and Price Stability
Lane defended the ECB’s interest rate increases as a measure intended to maintain economic stability and contain inflation.
He warned that sustained inflation of 3% or 4% would have significant consequences for households and could contribute to higher long-term interest rates if businesses and consumers began expecting elevated inflation to persist.
Lane also said governments should incorporate higher borrowing costs into their budget planning while prioritising structural reforms intended to support economic growth.
His comments highlighted the interaction between global AI investment, bond market conditions, energy prices and domestic fiscal policies as the ECB evaluates the appropriate direction of monetary policy.
