American technology companies are facing rising debt financing costs due to growing capital requirements for artificial intelligence infrastructure. Bloomberg data shows that the interest rate premium paid by US investment grade tech firms over the broader market has reached its highest level since 2003. To offset these costs, many companies are turning to cross-market financing, with the eurozone becoming a popular issuance hub due to its relatively lower benchmark interest rates. However, as debt issuance volumes increase, investors may demand higher yields, potentially forcing corporations to offer elevated interest rates to attract buyers for new bonds.
Financial pressures are already impacting tech firms' capital allocation strategies. Share repurchases by Microsoft, Alphabet, Amazon, Meta, and Oracle dropped 83% year over year in the first three quarters of this year, falling from $81.8 billion to $13.6 billion. This sharp decline in buybacks threatens a key support for tech stock valuations, as reduced share counts historically boosted earnings per share even without net income growth. With buyback volume contracting, companies must now rely on actual profit expansion to drive per share earnings higher.
As AI capital expenditure expands, market attention is shifting to whether this investment cycle can be sustained and the potential volatility of a slowdown. Reuters cited analysts noting that amid Middle East conflicts elevating energy prices, the US economy might already be in recession were it not for AI spending. A deceleration in AI expenditures could have global ripple effects, particularly given foreign investors' exposure to US asset markets.
Nathan Sheets, Global Chief Economist at Citigroup, stated, "There are so many places where there are inflationary pressures manifesting themselves in the economy. I think that at the moment maybe our protection against a slowing of growth is AI investment, exports, production are just so robust." Constance Hunter, Chief Economist and Head of Research at Economist Enterprise, added, "In the U.S., a lot of the incremental growth and consumption is coming from the wealth effect, and of course, that is really being fueled by the AI boom in terms of the equity market, so there is, I think, significant concentration risk. If we see the AI boom falter, I think you're going to see pretty significant fallout."
