Pimco leveraged‑finance chief David Forgash warned investors that junk‑bond issuance financing data‑center construction is fragmenting into winners and losers. A year ago the segment was negligible; today it accounts for roughly 4% of the overall high‑yield market. Forgash said Bloomberg TV that industry participants expect the share to climb to 10% within two years. It reshapes developer funding and broader pricing strategies.

Rapid growth stems from cloud providers scrambling for capacity, pushing developers to tap leveraged finance rather than traditional bank loans. The surge has tightened credit spreads on data‑center junk bonds, nudging yields higher and prompting rating agencies to scrutinize cash‑flow assumptions. Investors with exposure risk heightened volatility as the nascent market lacks historical performance benchmarks. The capital inflow also pressures landlords to upgrade infrastructure quickly.

Portfolio managers must now differentiate projects that generate stable tenancy from speculative builds. Those that secure long‑term contracts can sustain debt service, while over‑leveraged sites risk default as tenancy churn rises. The emerging split suggests that credit analysts will treat data‑center junk as a distinct sub‑sector rather than a generic high‑yield slice.
