Floating Rate Debt in a High Rate World

The Federal Open Market Committee’s decision on Wednesday, May 7, to hold its target range at 4¼ %-4½ % capped five consecutive meetings without a rate cut and cemented the Secured Overnight Financing Rate (SOFR) near 4.3%.3 Two years ago SOFR was barely a rounding error at 0.05 %. That tectonic shift has been a windfall for lenders who own floating-rate paper and a mounting headache for the companies obliged to pay those coupons. With roughly $1.14 trillion in U.S. broadly syndicated loans outstanding and an additional $190 billion of new collateralized-loan obligations (CLOs) priced last year, floating-rate finance is no niche backwater—it is now the backbone of corporate leverage.1, 2 Whether it remains a safe harbour or turns into a storm surge depends on what happens between now and the looming maturity wall of 2026-27.

During the zero-rate era, shifting from fixed to floating shaved 10–15 basis points off new-money costs. The incentive was irresistible: institutional loan issuance hit a record $1.36 trillion in 2024, while investment-grade companies more than doubled their use of floaters to roughly $125 billion.4, 8 Every deal found a ready bid because CLOs, which must buy floating loans, were minting new vehicles at a record pace, “originate to distribute” on overdrive. Yet floating debt is inherently path-dependent: once the Fed hikes, coupons re-price immediately and borrowers lose the option to glide back into fixed-rate funding without paying up.

For investors the strategy has worked handsomely. The Morningstar LSTA Leveraged Loan Index delivered an 8.95 percent total return in 2024, its best year since 2016 and a mirror image of the 2022 fixed-income rout.1 Because loan prices hover near par when coupons reset every quarter, mark-to-market volatility has been minimal. Money-market funds, insurers and pension plans have treated the asset class as a duration-free income machine. But that comfort rests on a knife-edge: the average new double-B loan now clears at just 210 basis points over SOFR, half the level seen during the 2020 pandemic. If front-end rates fall sharply, the coupon could collapse overnight while the price would have little room to rally beyond par.

What delights the lender burdens the borrower. Fitch estimates each 25-basis-point uptick in SOFR adds about $3.5 billion in annual interest expense across the leveraged-loan universe; holding today’s rate through 2026 would drain roughly $60 billion a year versus the 2021 baseline.5 Single-B companies, the market’s center of gravity, have watched cash-flow coverage of interest slide from 2.8× to 1.7x in just two years.7 Many sponsors hedged their LBO loans with three-year caps when rates were near zero; rolling those hedges today costs mid-single-digit percentages of notional, a price few private-equity models can absorb. Skipping the hedge is an even riskier wager hoping that the Fed will ride to the rescue in time.

Headline default rates remain manageable, 5.2 percent for leveraged loans versus 2.5 percent for high-yield bonds, according to Fitch’s March tally, but the composition of distress is telling.5 Floating-rate instruments accounted for 59 percent of all debt that defaulted in 2024 even though they represent only about half of outstanding corporate leverage.7 Covenant-lite structures allow companies to limp along longer than in past cycles, and CLO tranches push first-loss exposure onto equity investors who signed up for double-digit returns. The system therefore leaks stress slowly—until a refinancing deadline forces hard choices.

Ratings-agency S&P Global calculates that U.S. speculative-grade borrowers must refinance roughly $397 billion in 2026 and another $416 billion in 2027.13 About half of that stack is floating-rate leveraged loans and revolvers, so the bill will arrive at whatever short-term rate prevails when the window opens. In theory, today’s market could still absorb that load at coupons north of 9 percent; in practice, the door could slam shut if economic growth cools or if a rapid Fed-cut cycle erodes the carry that keeps lenders interested.

Regional banks avoided the worst of last year’s deposit flight, yet their balance sheets still contain sizeable revolving-credit facilities indexed to SOFR. Deposit betas—how quickly banks pass higher rates to customers—have climbed above 70 percent, squeezing net-interest margins just as loan spreads tighten. The Federal Reserve’s April 2025 Financial Stability Report flagged leveraged-loan quality as a “prominent vulnerability,” hinting that regulators may force more conservative loss-given-default assumptions in stress tests.1

Portfolio managers face a delicate timing game. Hedging loan exposure with pay-fixed swaps locks in today’s rich coupon but incurs an immediate negative carry; sitting tight delivers income but risks price slippage if refinancing dries up. Some managers are climbing the capital stack, favouring first-lien loans that have recovered more than 70 percent in recent bankruptcies. Others prefer three-month Treasury bills near 5 percent, sacrificing yield upside for instant liquidity. The common thread: nobody wants to be the marginal buyer of a nine-percent loan the day after SOFR drops to two.

Floating-rate debt has earned its reputation as a portfolio stabilizer, but its very resilience can lull investors into ignoring the pressure building on the other side of the ledger. Every month that SOFR holds above four percent chips away at corporate cash flow and inches the maturity wall closer. Whether floating paper proves a safe haven or a hidden risk will hinge less on the direction of rates than on the depth of investors’ appetite when the refinancing bill finally comes due.
