Card payments work until they do not. A power cut disables terminals. A network outage takes payment processing offline regionally. A card is blocked for suspected fraud at an inconvenient moment. An account is frozen during a dispute.
None of these is common. All of them have happened at scale, and the response is the same: a modest amount of physical cash, held where you can reach it.
What changed in 2026
- Cashless payment continued to dominate. Card and phone payment remained the default nearly everywhere.
- Outages kept demonstrating the gap. Payment network and power failures continued to produce localised cash-only periods.
- Cash acceptance declined. Some businesses stopped accepting cash entirely, which limits where it helps.
- Offline payment features improved. Some payment systems gained limited offline capability, partially addressing the gap.
Why it still matters
The scenarios are specific and real.
Power cuts disable terminals. Businesses that stay open operate cash-only, and cash machines do not work either.
Payment network outages have taken card processing offline across regions for hours at a time.
Card blocks happen at inconvenient moments — a fraud algorithm reacting to unusual activity, frequently while travelling.
Account freezes during a dispute or investigation can remove access to funds for days.
Natural events disrupt infrastructure broadly, and cash is what continues to function.
In each case, the requirement is modest: enough for food, fuel, and transport for a few days.
How much and in what form

Guidance |
| Amount |
A few days of essentials, not a savings buffer |
| Denominations |
Small — nobody can make change |
| Locations |
Split across home, vehicle, and person |
| Storage at home |
Fire-rated safe, not a drawer |
| Review |
Check annually; notes get withdrawn |
Small denominations are the detail people get wrong. During an outage, businesses have no card system and limited change. Large notes are difficult to use and may be refused. A stack of small notes is far more useful than the same total in large ones.
Splitting locations addresses the failure modes. Cash at home does not help if you cannot get home. Cash in a wallet is lost with the wallet. A small amount in a vehicle, a small amount on your person, and the bulk at home covers more situations than any single location.
At home, in a safe. A drawer is where burglars look, and cash is uninsured — see fireproof safe.
Keep it modest
The costs of holding cash are real and argue against holding much.
Inflation erodes it continuously, and it earns nothing.
Theft and loss are uninsured in most household policies beyond a small limit.
Fire destroys it, unless it is in a rated safe.
So this is a resilience measure with a specific purpose, not a store of value. Beyond a few days of essentials, money belongs somewhere it earns a return and is protected — see the emergency fund guide for the tier above this.
The related consideration is that cash is not universally accepted any more. Some businesses have gone cashless entirely, which limits where it helps. That argues for keeping the amount modest rather than for abandoning the idea, since the businesses that matter during an outage — small shops, fuel stations, transport — tend to be the ones that still take it.
Common mistakes
- Large notes only. Difficult to use, may be refused.
- All in one place. Single point of failure.
- In a drawer. Where burglars look, and no fire protection.
- Holding too much. Uninsured and losing value.
- Never reviewing. Notes get withdrawn from circulation.
- Treating it as savings. Wrong purpose, wrong place.
- Forgetting foreign currency when travelling. A local outage abroad is worse.
FAQ
How much is right?
Enough for a few days of essentials for your household — food, fuel, transport. The specific figure depends on your costs; the principle is days, not weeks.
Does this apply if my area is fully cashless?
Less, and outages still produce cash-only periods in businesses that keep a float. A smaller amount remains worthwhile.
What about keeping it in a bank box?
Inaccessible outside banking hours, which defeats the purpose entirely — see safe deposit box.
Should I hold foreign currency?
For travel, a small amount of local currency on arrival is prudent, particularly where card acceptance is uneven. Not something to hold at home otherwise.
