US Banks’ Credit Binge: Why Lending to Data Centers Is the Quietest Bubble on Wall Street

Every so often, Wall Street finds a new way to chase yield, and this time, it is hiding in plain sight. While everyone is busy hand-wringing over tariffs, AI hype, and the latest geopolitical flameout, the real story is unfolding in the credit markets. US banks are quietly shoveling billions into data center construction, underwriting credit lines and bonds for hyperscalers who have become the new oil barons of the digital age. The numbers are staggering, the risks are mounting, and the market is barely blinking.

According to Seeking Alpha, big banks are riding the data center boom, extending massive credit facilities and snapping up bonds to fund the infrastructure arms race. The rationale is simple: hyperscalers like Amazon, Microsoft, and Google are insatiable. They need power, cooling, and square footage to feed the AI beast, and banks are all too happy to oblige. The result is a lending binge that rivals the shale boom of the 2010s, with none of the regulatory scrutiny.

The facts are hard to ignore. In the last quarter alone, US banks originated over $24 billion in data center loans, a 19% jump from the previous year. Bond issuance tied to data center REITs and infrastructure providers hit a record $17.3 billion, according to Bloomberg. The spread on these deals is compressing, with banks accepting razor-thin margins in exchange for volume. The logic is that data centers are the ultimate secular growth story, immune to macro shocks and policy risk. But that is exactly what the market thought about subprime mortgages in 2006.

The context is even more surreal. While equity markets have been whipsawed by credit stress and geopolitical risk, the credit market for data centers has been a one-way train. The Dow is barely hanging on to a +0.05% gain for February, and the S&P 500 is wrestling with credit crunch fears and month-end flows. Yet, banks are tripping over themselves to lend to anyone with a server farm and a power contract. The disconnect is glaring, and the risk is that the market is underpricing tail risk.

The analysis here is not that data centers are a bad business. Far from it. The problem is that the lending standards are eroding, and the market is treating data center credit as a risk-free asset. Banks are syndicating deals with minimal covenants, and the duration risk is getting kicked down the road. The last time we saw this kind of behavior, it ended with a credit event that nobody saw coming. The irony is that the very AI algorithms driving demand for data centers are also being used to underwrite the loans. If that is not a recipe for a feedback loop, nothing is.

The real risk is not just credit quality, it is liquidity. The market for data center bonds is deep when times are good, but it is a ghost town when risk appetite dries up. The recent defaults among private equity and tech firms are a warning sign. If the credit cycle turns, banks could be left holding the bag on billions in illiquid debt. The market is pricing in perfection, and that is always a mistake.

Strykr Watch

The technicals on data center REITs are flashing late-cycle signals. Valuations are stretched, with the average price-to-FFO at 27x, well above the 10-year average of 19x. Credit spreads have compressed to 110bps over Treasuries, the tightest since 2018. Watch for a widening of spreads as a canary in the coal mine. The Strykr Watch to watch are the 200-day moving average on the top three data center REITs, which are all within 3% of being breached. If those levels break, expect a rush for the exits.

The risk here is that banks are overexposed to a single sector, and the market is underestimating the correlation risk. If AI demand slows or power costs spike, the entire sector could reprice overnight. The technicals are telling you that the market is crowded, and the risk is to the downside.

The opportunity is to fade the consensus. Credit default swaps on data center bonds are trading at multi-year lows, and the risk-reward for buying protection has never been better. For equity traders, the play is to short the weakest data center REITs on a break of the 200-day, with a tight stop above recent highs.

Strykr Take

Wall Street loves a good bubble, and the data center credit binge is the quietest one in years. The market is pricing in perfection, but the risks are piling up. The smart money is buying protection and waiting for the cracks to show. This is not the time to chase yield. It is the time to get defensive.
