As regulators, fintechs, and central banks inch or giant-leap towards the ideal of a “cashless society”, the conversation has rightly focused on consumer choice while conveniently side-stepped issues of cost transparency. But beyond these valid points lies a more fundamental issue: resilience.
The digital payments infrastructure that underpins modern commerce is efficient—until it isn’t. It has been designed to support far higher volumes than cash ever could. In countries like the UK, discussions around orderly rationalisation of cash infrastructure have acknowledged this reality. But to leap from rationalisation to obsolescence is not just risky—it’s misguided.
A recent post by Graham Mott (link), of the payments clearing house LINK in Linkedin, reminds us that resilience is not just about redundancy—it’s about preserving diversity in payment channels. John Howells, also of LINK (link) goes further, warning of a two-tier society in which those excluded from digital systems are left behind. Both are right—but this argument should extend beyond social access to systemic risk.
The past decade has provided compelling real-world examples where cash has proven essential when digital payments failed. These aren’t fringe cases—they span advanced, emerging, and developing economies:
1. India – Demonetisation (2016)
The rapid removal of high-value notes and a parallel push to digital platforms exposed huge infrastructure gaps, particularly in rural areas, where cash remained vital.
2. Puerto Rico – Hurricane Maria (2017)
The total collapse of power and internet left cash as the only operational means of exchange during recovery efforts.
3. United Kingdom – TSB IT Meltdown (2018)
Millions were locked out of digital services for days. The bank had to resort to manual distribution of cash and direct ATM support.
4. Sweden – IT Outages & Resilience Warnings (2021)
When supermarket tills failed, cash-only transactions became the norm. Sweden’s own civil contingencies agency has since advised households to keep cash on hand in case of cyberattacks or conflict.
5. Canada – Rogers Telecom Blackout (2022)
A national outage paralysed debit card systems and mobile networks. Many consumers found cash was the only option for fuel, food, and transport.
6. Mexico – Hurricane Otis in Acapulco (2023)
The destruction of digital infrastructure led monetary authorities to activate Plan Billetes, airlifting cash into the region to restore basic commerce and coordinate delivery with commercial banks (through mobile branches and ATMs) to ensure people could buy essentials.
7. Nigeria – Naira Redesign Crisis (2023)
A monetary policy shock and under-prepared digital infrastructure left millions without cash or functioning mobile payments. Long queues, protests, and informal exchanges ensued.
8. Spain & Europe – Power Grid Collapse (2025)
Electricity failures across parts of Spain, Portugal, and France knocked out payment systems. Authorities encouraged citizens to carry cash as mobile networks, card machines and ATMs went offline.
These are not hypothetical outlier cases—they are a feature of 21st-century economic life: almost one major event per annum during the last decade. This suggests that every advanced biometric, NFC-enabled, or tokenised payment product we build must have a failsafe that doesn’t rely on power, connectivity, or centralised databases.
Why should fintech care?
This isn’t about nostalgia or clinging to old systems. It’s about designing a truly antifragile ecosystem, where redundancy is built in and payment continuity is guaranteed in every scenario. Fintech innovators should view cash not as competition, but as a complementary anchor that underwrites trust in the system. Yet practitioners and regulators, particularly in South East Asia, have no plans for it…. risking getting caught with their pants down. There are, of course, other priorities for them, fueling super apps such as fiscal surveillance, for transactions to remain digital and the need to promote consumer expenditure.
Moreover, in a world of rising climate risk, cyber vulnerability, and geopolitical uncertainty, payment resilience will increasingly become a regulated feature, not a design afterthought. Startups and incumbent providers who build for interoperability with cash, especially in crisis response, could find themselves in a strategic sweet spot with governments, humanitarian agencies, and central banks.
In short, the utopia of a cashless future may sound sleek—but it risks turning into a dystopia of exclusion and fragility. Let’s not build a system so streamlined that it snaps when tested.
Rationalisation is sensible. Redundancy is essential. And resilience begins with respecting the role of cash.
