No bank announces that it has stopped lending. What happens instead is that the process gets slower, the questions get harder, the covenants get tighter, and the answer arrives as a series of small obstacles rather than a refusal. By the time a business owner concludes that credit has become difficult to obtain, the change has usually been under way for a couple of quarters.
Price is the last thing to move
The intuitive model of credit tightening is that loans become more expensive. That is not primarily how it works.
Lending to small firms is subject to a problem economists call adverse selection. The bank knows less about a borrower’s prospects than the borrower does. If the bank responds to rising risk by raising rates, the borrowers most willing to accept the higher rate are disproportionately those with the riskiest plans — the ones who either expect returns high enough to justify it or do not expect to repay at all. The safest borrowers withdraw first.
Raising the price therefore worsens the quality of the loan book. Rationing does not. Faced with rising risk, a rational lender tightens standards and lends less, rather than lending the same amount at a higher price.
This is why credit availability and credit pricing move on different schedules, and why a business can find borrowing impossible at a moment when quoted rates look unremarkable.
What tightening looks like from the borrower’s side
The adjustments are mostly non-price, which is exactly why they are hard to detect.
- Loan-to-value limits fall. An asset that supported 80 percent borrowing now supports 65. The rate is unchanged; the amount available drops by a fifth.
- Personal guarantees expand. Facilities previously secured on business assets begin requiring personal guarantees, or existing guarantees are extended.
- Covenants tighten. Leverage and coverage tests are set closer to current performance, leaving less headroom before a technical breach.
- Documentation requirements increase. More history, more detail, more frequent reporting. This appears as administrative friction rather than a credit decision.
- Approval moves up. Decisions that a branch or relationship manager could make now go to a credit committee. The visible symptom is that everything takes three weeks longer.
- Renewals stop being automatic. A revolving facility renewed without discussion for years is suddenly re-underwritten.
That last one is the most dangerous, because it converts what a business treats as permanent working capital into a facility that can be reduced or withdrawn at renewal — often at the point in the cycle when it is most needed.
Why smaller firms absorb the most
Credit tightening is not distributed evenly, and the unevenness is structural rather than deliberate.
A large company with a credit rating can issue bonds. If bank lending tightens, it substitutes toward capital markets. A small firm dependent on a single banking relationship has no substitute — when that relationship tightens, its options are exhausted.
Smaller loans also carry higher fixed underwriting costs per unit lent, so they are the first thing a bank reduces when it is economising on balance sheet or credit resource. And smaller firms have less audited financial history, which makes them harder to underwrite precisely when underwriting standards rise.
The result is that monetary tightening bites hardest on the businesses least equipped to withstand it — a distributional consequence of the credit channel we set out in how central bank rate decisions reach the real economy.
The published warning
Central banks in most major economies survey senior loan officers quarterly and publish the results. The surveys ask directly whether standards have tightened or loosened, and for which categories of borrower.
This is among the most useful publicly available indicators for a small business, and among the least read by the people it concerns. It leads observable credit conditions by roughly a quarter or two, because it captures decisions banks have taken but not yet fully implemented across their books.
A business that sees standards tightening in the survey has a window — before its own renewal arrives — to act.
What to do with the warning
- Draw on facilities before you need them. Counter-intuitive and expensive in interest, but an undrawn facility can be reduced. Drawn funds in your account cannot be taken back.
- Renew early. Renegotiating a facility with nine months remaining is a different conversation from renegotiating one with six weeks remaining.
- Establish a second relationship before you need it. Banks lend to businesses that do not appear to need the money. The time to open a second line is when the first is comfortable.
- Track your covenant headroom monthly. Know how far performance can deteriorate before a test is breached, and raise it with the lender before it happens rather than after.
- Keep the reporting current. When approval moves to a credit committee, the file that is complete and current gets approved and the one that is not gets deferred.
None of this is exotic. It is the ordinary discipline of treating access to credit as a variable rather than a constant — which it is, and which businesses tend to discover at the least convenient moment.
