The recent spike in global bond yields reflects a robust global growth story, heavily influenced by the AI investment boom. Despite higher yields, inflation expectations (break-evens) remain stable, indicating confidence in central banks. The move is in real yields, suggesting bonds need higher real returns to compete with AI-driven equities.

The recent spike in long-term U.S. Treasury yields isn't just about inflation; it's being driven by market mechanics. Investors and dealers are preparing for a large supply of AI-related corporate bonds by selling existing assets. Dealers then hedge their increased inventory by selling liquid U.S. Treasurys, pushing government bond yields higher.

Jeffrey Schmid suggests the massive capital investment required for the AI and data center build-out is creating significant new demand for credit. This demand competes directly with public sector borrowing and other commercial needs, which in turn puts upward pressure on bond yields as part of a classic supply-and-demand dynamic for money.

The AI build-out increases real interest rates by demanding vast amounts of capital, crowding out other investments. Simultaneously, it pushes up nominal rates by creating inflationary pressure on physical resources like labor, energy, and materials needed for data centers.

The current US rates sell-off is characterized by rising real yields rather than just higher inflation expectations. This specific type of move is the most damaging for emerging markets because it tightens global financial conditions, making it difficult for EM rates to decouple from US pressure.

Beyond government deficits, the massive capital investment required for the AI revolution is a significant driver of demand for money. This multi-trillion dollar build-out for data centers and technology competes with all other borrowing needs, putting fundamental upward pressure on interest rates, the price of capital.

The sustained rise in global bond yields isn't attributable to a single driver like U.S. policy or inflation alone. Instead, it's the powerful and simultaneous combination of persistent government deficits, new private sector borrowing for AI, and recent inflationary shocks that is fundamentally and broadly repricing the cost of capital.

Tech leaders argue that the AI buildout is a key driver of rising interest rates. The demand for capital from hyperscalers and data center projects is so immense—borrowing at a 'nation scale'—that it creates a highly attractive alternative to government debt, forcing yields higher to compete for investment.

Massive capital expenditure in AI is driving a broad, inflationary expansion across all assets. This pressure is a key reason interest rates must rise significantly to find balance, potentially requiring a 30-year yield in the 6% range and a Fed Funds rate over 5.5%.
