Strong economic growth drives recent surge in global interest rates

Since early autumn, sovereign bond rates have risen sharply in the United States, Japan and several European nations, reaching levels not seen in about twenty years. Conventional commentary attributes the hikes to extended geopolitical tensions, higher fuel costs and mounting sovereign debt burdens. However, market data indicates that short-term inflation expectations stay relatively anchored, oil supplies are intact, and risk premiums on government debt have not widened dramatically.

Valtteri Ahti, chief strategist at Evlin, points to vigorous economic growth as the dominant force behind the rate increases, highlighting a global AI boom that is spurring the construction of data centers worldwide. This investment wave is spilling over into manufacturing and building firms, creating broad-based demand. Although Ahti acknowledges genuine risks in oil markets and sovereign debt, current evidence suggests that the growth-driven demand surge is the key driver of higher borrowing costs. The situation contrasts with earlier periods of persistently low rates, suggesting a shift toward historically normal interest-rate levels if growth remains strong.
