AI Firms Issue $250 Billion in Bonds, Raising Borrowing Costs for European Governments

Four major US technology companies have issued approximately $250 billion in dollar-denominated bonds since the start of 2025. This massive influx of corporate debt is competing directly with European sovereign borrowers for investor capital. The total AI infrastructure investment has exceeded $1 trillion, straining available funds in fixed income markets.

Amazon, Alphabet, Meta, and Oracle led this borrowing surge. They sold an additional €37 billion in euro-denominated bonds. Microsoft recently joined the group with a new $25 billion bond sale. Goldman Sachs projects that total new bond sales from these hyperscalers will reach $420 billion next year. ING estimates that €60 billion of this amount will be issued in euros.

European governments face rising costs as a result. France, which has public debt equal to 119% of its GDP and a deficit above 5%, saw yields on its 10-year bonds climb from 3.7% to nearly 5% over the past six months. The country's interest bill is expected to rise from €79 billion to €91 billion next year. It will surpass €100 billion by 2028.

Viktor Hjort, global head of credit strategy at BNP Paribas, described the situation as bond abundance. He told Deutsche Welle that the presence of hyperscalers creates competition between corporates and governments for available fixed income funds. Bond yields jumped last month due to rebounding energy prices and France's political crisis. This movement occurred even though nervous investors typically seek government bonds during uncertain times.

European companies are also feeling the pressure. Goldman Sachs reported that interest costs as a share of sales for firms in the Stoxx 600 index have risen by nearly half since 2022. This increase has cut earnings by more than 5%. Analysts suggest that European firms may need to reduce investments in new plants and equipment to prioritize loan repayments. The European Central Bank warned in August that these inflows could make it harder for other economic sectors to access finance.

The impact extends to local governments. A January study by the OECD found that borrowing costs for cities and regions tend to rise where AI adoption is fastest. Christos Makridis, co-author of the study, noted that this contrasts with the United States, where AI investments are linked to lower borrowing costs for municipalities. The pressure on regional budgets threatens funding for schools, transport, and infrastructure across several European countries.

US Big Tech companies plan to issue additional billions in new bonds next year. This continued demand for capital adds pressure to an already strained fiscal environment in Europe. European taxpayers may end up paying more on their own governments' debt to help finance an AI boom across the Atlantic.
