The companies that borrowed cheap in 2021 now owe the bill — all at once

In 2021, a mid-cap retailer we will not name borrowed at an interest rate that, viewed from today, looks almost imaginary: a little over two per cent, fixed, for five years. Its treasurer was praised for prudence. The money funded new stores, a warehouse, a share buyback. Nobody in the room thought to ask what would happen when the loan matured, because in 2021 the future cost of money looked like the present cost of money, which was to say, nearly nothing. That loan comes due this year. To replace it, the company will pay close to seven per cent. The same debt, the same business, more than triple the bill.

Multiply that arithmetic across an entire economy and you have what bankers, with characteristic understatement, call the maturity wall: the great mass of cheap, fixed-rate corporate debt issued during the easy-money years, now reaching the end of its term and forced to refinance into a world that has changed beyond recognition. The wall is not a forecast. It is a calendar. The bonds and loans were dated when they were signed, and the dates are arriving on schedule, regardless of whether the companies behind them are ready.

How the trap was built

It is worth being precise about how benign the original sin looked. For most of 2020 and 2021, central banks held policy rates near zero and bought bonds by the trillion, and the price of corporate credit collapsed to levels without modern precedent. Even shaky borrowers could raise money at rates that, in any normal decade, would have been reserved for governments. Treasurers did exactly what the incentives told them to: they borrowed long, borrowed cheap and locked it in. The decision was not reckless. Given the information available, it was textbook. The recklessness, if there was any, was systemic — an entire corporate sector planning as though the price of money would never normalise.

Then it normalised, violently. The fastest tightening cycle in forty years took policy rates from the floor to levels not seen since before the financial crisis, and they have stayed there. As we reported when the central bank held rates again this month, the relief that markets keep pricing in keeps failing to arrive. For a company refinancing today, the cost of the new loan is not a little higher than the old one. It is a different order of magnitude — and for businesses whose entire model was calibrated to near-zero borrowing, that difference is existential.

That sentence describes the zombies — the firms that have limped along for years generating just enough cash to service ultra-cheap debt but never enough to repay it or to thrive. In the free-money era they were sustainable in the narrow sense that they did not default. The maturity wall removes that protection. A company that could service two-per-cent debt but cannot service seven-per-cent debt is not facing a cash-flow inconvenience; it is facing a question about whether it should exist at all. Estimates of how many such firms populate the European mid-market vary, but every restructuring desk we spoke to reported the same thing: the phone is ringing far more than it did a year ago.

Who is filling the gap

Into this breach has stepped one of the decade's great financial growth stories: private credit. As banks turned cautious and the public bond market grew choosy, a wave of funds raised vast pools of capital to lend directly to companies that could no longer borrow cheaply elsewhere. For a stressed borrower facing the wall, a private-credit fund can be a lifeline — flexible, fast, willing to lend where a bank will not. But the lifeline is not charity. These funds price for the risk they are taking, often in the high single or low double digits, and they write covenants that hand them real power if things go wrong. The gap is being filled, in other words, but on terms that transfer a great deal of leverage from the borrower to the lender.

The concern that keeps regulators awake is not that private credit exists, but that it has grown so fast, so opaquely, that nobody is entirely sure where the risk has ended up. The cheap debt of the easy years did not vanish; it migrated, from bank balance sheets to bond funds to private vehicles whose holdings are not marked to market every day. In a benign scenario, that dispersion is a feature: the losses, when they come, are spread across many patient investors rather than concentrated in a few systemic banks. In a darker one, it is simply a fog — risk that has been moved out of the light, not out of existence.

The sectors with nowhere to hide

The pain will not fall evenly. Three areas recur in every conversation. The first is commercial real estate, the textbook victim of higher rates: property bought with cheap leverage, valued on the assumption that rates would stay low, and now worth less precisely as the cost of carrying it has soared. Refinancing a half-empty office tower at today's rates, against a building worth less than the loan, is the kind of problem that does not have a clean solution. The second is leveraged buyouts — companies taken private at rich valuations with mountains of debt, on the theory that cheap money would let the new owners refinance and grow. That theory has not survived contact with the rate cycle.

The third is parts of retail and consumer-facing business, where thin margins leave no room to absorb a tripling of interest costs, and where the squeeze on household budgets compounds the problem from the demand side. A retailer paying far more to service its debt, while its customers have less to spend, is caught in a vice from both ends. It is no accident that this is the same terrain where household purchasing power is quietly eroding; the corporate maturity wall and the household squeeze are two faces of the same higher-rate world.

It would be wrong to end on pure alarm. A maturity wall is not a financial crisis in the 2008 sense; it is a slow, grinding repricing, spread over years, that most large and genuinely profitable companies will absorb without drama. They will pay more, trim their ambitions and move on. The drama is concentrated at the margin — among the over-leveraged, the marginally viable and the unlucky, the businesses that mistook cheap money for a sound model. For them, the bill that came due in 2021's fine print is now, in 2026, simply due.

What the wall ultimately delivers is a sorting. The years of free money blurred the line between a good business and a well-financed one, because almost anything could be financed. Higher rates redraw that line, sharply and without sentiment. The companies on the right side of it will look, in hindsight, as though they were always going to be fine. The ones on the wrong side will discover, often suddenly, that the cheapest decision they ever made was also the most expensive. The reckoning is not coming. It is here, and it arrives one maturity date at a time.
