US Big Tech expands presence in euro area bond markets

Major US technology companies, often referred to as hyperscalers, are increasingly utilizing the euro area corporate bond market to fund massive investments in artificial intelligence and data center infrastructure. Companies such as Amazon, Alphabet, and Microsoft are shifting from self-funding toward external debt issuance to meet projected capital expenditure needs, which could exceed $1 trillion by 2028.

The European Central Bank (ECB) has noted that while these “reverse Yankee” bonds have improved credit quality and increased activity in long-term maturities within the euro investment-grade market, they pose significant structural risks. These risks include increased market concentration and heightened investor exposure to the US economy and the technology sector.

A primary concern is the potential for a “crowding out” effect. As hyperscalers demand larger amounts of capital, they may compete with European corporations and governments for limited investor funds. This competition could force investors to reallocate assets away from other sectors, potentially driving up borrowing costs for European companies and impacting the availability of capital for diverse economic industries.
