Almost half of adults couldn't face an unexpected expense without serious difficulty

According to the World Bank's Global Findex 2021, only 55% of adults in developing economies could get extra money for an emergency within 30 days without much difficulty. For everyone else, a surprise expense becomes a problem.

What an emergency fund is and why it's the foundation of financial health

An emergency fund is a reserve of easily accessible savings worth three to six months of essential spending, available without penalty and kept apart from long-term savings. It is the first level of any personal financial health structure.

Its job isn't to grow. It's to be there. It absorbs the unexpected (losing a job, a car breakdown, an uncovered medical bill, a home repair) without having to turn to consumer credit or expensive loans.

Without this cushion, any surprise becomes a financial emergency that can trigger a debt cycle that is hard to break: you borrow to cover the surprise, the loan charges interest, the interest leaves less room to save, and the cycle repeats with the next surprise.

The most common explanation is that there's no room in the budget to save. But research on financial behaviour shows the link between income and saving rate is more complex than it looks. People with similar incomes save at very different rates depending on their habits and financial knowledge.

The best-documented reason is the lack of an automatic saving habit. When saving isn't automatic (when money isn't set aside before spending), it tends not to happen. This is a basic principle of behavioural finance that isn't taught at school, and it has direct consequences for the financial resilience of millions of people.

Add to this some well-documented cognitive biases: the tendency to put present consumption ahead of future wellbeing (hyperbolic discounting), the difficulty of picturing negative future scenarios, and the lack of a concrete reference for how much is "enough".

What happens without a cushion: the real cost of the unexpected

When there's no emergency fund, the surprise is paid for with debt. The easiest options for someone with no savings tend to be the most expensive: high-interest credit cards, quick loans whose annual rate can go above 100% in some cases, or deferred payments with high fees.

That cost could have been avoided entirely with the habit of setting aside a small amount every month for a year.

For lower- and middle-income families, this cycle can be devastating. Financial fragility isn't just stress: it correlates with worse job performance, worse health decisions and greater vulnerability to any economic change.

How to teach the emergency saving habit in the classroom

Emergency saving isn't just a concept: it's a habit. And habits are built, not inherited. Financial education in the classroom can work on this habit in practical ways: budget simulations where savings come out first, surprise scenarios that need decisions on the spot, or personalised calculations of how big "your cushion" would need to be.

The most effective financial education programmes don't stop at explaining what an emergency fund is. They get students to calculate it, plan it and build it into a mock budget, creating the familiarity they need for that behaviour to be within reach when the real moment comes.

And financial education works: a meta-analysis of 76 randomised experiments (Kaiser, Lusardi, Menkhoff and Urban, Journal of Financial Economics, 2022) found that it improves both knowledge and behaviours such as saving, with effects comparable to other educational interventions.
