European Central Bank chief economist Philip Lane said increased investment in artificial intelligence, particularly in the United States, is contributing to higher long-term bond yields, adding another global factor to the ECB’s assessment of monetary policy.
Speaking in an interview with Italian news agency ANSA published Tuesday, Lane identified AI investment as a major development affecting international economic conditions.
He explained that U.S. companies are taking on substantial long-term debt to finance AI-related spending, contributing to upward pressure on bond yields.
The expansion of artificial intelligence is also affecting global trade flows, with demand increasing for semiconductor chips and other materials associated with the technology. Lane noted that European businesses participate in parts of this supply chain.
Higher long-term interest rates can restrict economic activity and reduce inflation in the eurozone, particularly when the increases originate from global rather than domestic developments, Lane said.
He added that the ECB would incorporate these effects into its assessment of inflation, economic risks and the appropriate level of policy interest rates.
ECB Monitors Energy Costs and Secondary Inflation Effects
Lane said energy prices remain an important consideration for monetary policy following the increases that have contributed to the ECB’s recent rate decisions.
Although energy costs have risen, he indicated that there has been limited evidence so far of substantial second-round inflation effects, where initial price increases spread more widely through the economy.
The extent of any further transmission remains uncertain, according to Lane, who cautioned against assuming that current conditions fit neatly into the ECB’s baseline or adverse economic projections.
Lane also discussed the eurozone’s performance during the summer, when a temporary reduction in energy prices following an understanding between Iran and the United States provided some support to economic activity.
He said renewed increases in energy costs and uncertainty surrounding the conflict have created questions about whether those conditions will continue.
Government Spending and Italian Inflation
Looking at fiscal policy, Lane noted that this year’s economic support includes Germany’s infrastructure and defence programme, alongside the concluding year of the European Union’s Next Generation recovery fund.
He indicated that the composition of fiscal support would change in the years ahead.
In Italy, where the latest reported inflation rate stood at 4.1%, Lane supported targeted assistance for households with lower incomes rather than broad-based fiscal expansion.
He said general increases in public spending would not help bring inflation back to the ECB’s 2% target within an appropriate timeframe.
The ECB’s September forecasts anticipate that Italian wages will increase faster than consumer prices in 2027 and 2028.
However, Lane warned that wage growth exceeding sustainable levels could affect foreign investment and employers’ willingness to recruit additional workers.
Interest Rate Policy and Long-Term Economic Stability
Lane reiterated the ECB’s position that interest rate increases are intended to preserve price stability.
He said inflation remaining at 3% or 4% would have substantial effects on households, while expectations of persistently elevated inflation could also contribute to rising long-term borrowing costs.
Lane advised governments to account for higher interest expenses when preparing public budgets and to focus on reforms that support economic growth.
His remarks outlined several considerations for ECB policymakers, including global borrowing linked to AI investment, energy market developments, inflation expectations and the future direction of fiscal policy.
