Recognition
Your overdraft shrank, or wasn't renewed at the level you needed
A lot of established businesses still think of an overdraft as their default working-capital buffer, because it was, for years. If yours has been reviewed unexpectedly or reduced, that's a market-wide pattern, not something specific to your business.
Why it happens
Banks have generally pulled back from large, flexible overdrafts
Banks have moved away from offering large, flexible overdrafts to SMEs, tightening limits, reviewing them more frequently, and pushing businesses toward separate, purpose-built facilities instead.
Where this fits
Business Finance / General, not a standalone facility any more
This isn't really its own facility category today, it's the situation that usually leads to Credit Lines.
Specialist insight
What usually replaces it
A revolving credit facility, structured separately from your day-to-day account, is the most common replacement. It works similarly in spirit, draw down what you need, repay it, draw it again, but it's sized and priced on its own terms rather than tied to your current account's limit, and it's less exposed to being quietly reduced at the bank's next internal review.
Decision helper
What typically fits
For genuinely small, occasional dips, an existing overdraft with your current bank can still be the simplest option, if you can get one at the size you need. The issue isn't that overdrafts are always wrong. It's that relying on one as your main working-capital buffer, at a size that matters to the business, has become a less reliable plan than it used to be.
Already have a facility and it's not enough any more? See I already have a debenture, can I still borrow more?
One thing we've noticed: the businesses caught out worst aren't the ones with weak finances, they're the ones who never replaced the overdraft with anything else because it hadn't been reduced yet. By the time a review notice arrives, there's no time left to arrange a proper facility. Sorting it before the review, not after, is the whole difference.
Alternatives and limitations
An overdraft is still the simplest tool for genuinely small, occasional cash dips. It stops being reliable once the business needs it to be a real, sizeable buffer, that's when a purpose-built credit line usually serves the business better.
