# Data center debt refinancing could add at least $380 million in costs

Data center developers could face at least $380 million in additional borrowing expenses if $13.4 billion of fixed-rate, dollar-denominated debt maturing in 2027 is fully refinanced at prevailing Treasury yields, Bloomberg reported, citing a new BloombergNEF analysis.

Using yields from October 2026, the analysis estimates a 2.85 percentage-point increase in interest rates on that debt. The calculation assumes credit spreads stay unchanged, making the projected increase conditional on both refinancing and the borrowing terms developers obtain.
