bank on

depend on something happening or being true

C1

What does "bank on sth" mean?

To bank on something means to be so confident that a particular outcome will happen that you make plans or decisions based on that assumption — essentially staking your hopes on it. The phrase carries a sense of risk: you are betting on something that isn't guaranteed. It is most naturally used in cautionary or negative contexts, warning someone not to assume too much. The fixed expression 'I wouldn't bank on it' is almost a conversational formula for casting doubt on someone's optimistic expectations. Unlike simply hoping for something, banking on it implies that your plans are already built around the assumed outcome.

Common Mistakes

To-infinitive instead of gerund

Confusing 'bank on' with 'count on' for people

'Bank on' focuses on outcomes and events, not on a person's trustworthiness or loyalty. When you want to say you rely on a person's character or dependability, 'count on' is the more natural choice.

I've always been able to count on her when things get difficult.
Using the present continuous

'Bank on' sounds unnatural in the present continuous. Use the present simple or a modal construction instead.

Usage

Frequently Asked Questions

Can 'bank on' be used in the passive, like 'the outcome was banked on'?

No — 'bank on' is almost never used in the passive, and attempts to do so sound very unnatural. The phrase always focuses on the person doing the assuming or predicting, not on the thing being relied upon. Stick to active constructions.

Does 'bank on' always suggest something might go wrong?

Not always, but it frequently appears in warnings and expressions of doubt, which gives it a cautionary tone. Even in positive sentences, the word implies a degree of risk — you're staking confidence on something that isn't certain. The phrase 'I wouldn't bank on it' has become so common that the verb as a whole carries a slightly sceptical flavour.

Is 'I wouldn't bank on it' a fixed expression?

It functions almost like one. It's a very common spoken response used to gently warn someone that what they're expecting may not happen. You can use it on its own as a complete response without specifying what you're doubting.

What kinds of things can follow 'bank on'?

You can bank on outcomes, events, or situations — things like a promotion, good weather, a deal going through, or support from a team. These can be noun phrases ('bank on a pay rise') or gerund clauses ('bank on things going smoothly'). The object should represent a predicted event or result, not a person being trusted for their character.

Is 'bank on' more British or more American?

It's used naturally in both British and American English with no significant difference in meaning or frequency. You'll encounter it in conversation, news journalism, and everyday writing on both sides of the Atlantic.
