When Digital Fails: Why Cash Still Matters in a Resilient Payments Ecosystem

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.

Slow and Steady Wins the Race: ATMs, Tuvalu, and the Digital Dream

Chapter 2 of Cash and Dash (Bátiz-Lazo, 2018) offers a timely reminder that major financial innovations often took years — even decades — to establish themselves. Far from being instant game-changers, technologies like the ATM spread unevenly, tangled in local infrastructure challenges, regulatory caution, and a general sense of “wait and see.”

A perfect illustration comes from Tuvalu, which in April 2025 finally installed its first-ever cash machine (Campbell, 2025). It’s surprising, at first glance, to think that in a world obsessed with mobile payments and digital wallets, there are still places only now getting access to what many consider basic banking services. Yet it also perfectly captures the deeper lesson: the transition to a fully digital economy is far from complete.

While fintech headlines celebrate real-time transfers, crypto experiments, and cashless cities, Tuvalu’s story shows the reality for smaller, more remote economies. Cash remains critical. Infrastructure development cannot be skipped. And often, “old” technology like ATMs is still a vital stepping stone towards wider financial inclusion.

The tale of Tuvalu isn’t a tale of being left behind — it’s a glimpse into the diverse and uneven journey that global digital transformation must navigate. Chapter 2 of Cash and Dash reminds us that even the ATM, now seen as a legacy technology, once faced scepticism and delay. Innovation is not only about speed; it’s about building trust, access, and infrastructure in ways that work for real communities.

If Tuvalu is only now welcoming its first cash machine, imagine how much opportunity — and challenge — lies ahead for a truly cashless world.

Postcrip 30-04-2025
Got the following comment from a colleague after reading this entry, which helps clarify the late development:

Three ATMs were established in Tuvalu as part of their disaster risk management programme following Cyclone Tino in 2020 following my advice to UNDP and the UN’s Global Cash Working Group. Interestingly, they are also configured to accept tokens, paper vouchers and bitcoin though only dispense physical currency. This policy is slowly being implemented across Polynesia, including in Vanuatu and Fifi.

Swipe, Reward, Repeat: Could Loyalty Programs Falter in a Tariff Downturn?

As we brace for a potential recession, the future of credit card rewards and points programs hangs in the balance. How will these perks evolve in an economic downturn? That was the super interesting question that I recently discussed with Juliana Kaplan from Business Insider.

From an international payments systems perspective, credit card rewards programmes have long been a strategic tool for issuers to drive customer acquisition and retention. According to Statista (2022), the US Consumer Payments Study of 2018, revealed that 80 per cent of the respondents preferred cash rebates as the most preferred type of credit card rewards program in the United States. This was followed by gift cards, merchandise, travel and experiences, in that order of preference. However, as we approach a period of heightened economic uncertainty and potential recession, the sustainability and structure of these schemes may come under pressure.

Historically, as shown in the work by Murthi et al. (2011), while rewards and affinity cards can attract lower-risk customers, they do not necessarily translate into greater profitability. In fact, such customers often have shorter lifespans with the issuer and may generate lower returns. In the Indian context, as Liu et al. (2012) found, low levels of consumer engagement in rewards programmes further dilute their effectiveness in fostering loyalty. Crucially, it is not the existence of a rewards programme that matters most, but the extent to which consumers are actively involved—particularly in redemption behaviours.

Against this backdrop, the latest data from the Federal Reserve (February 2025) shows a notable uptick in credit card delinquency rates, with a sharp rise among lower-income and subprime borrowers. This is particularly significant because many credit card rewards schemes are funded indirectly through interchange fees and the interest paid by revolvers—those who carry balances. If delinquency rates continue to climb, this revenue model becomes less reliable.

Source: Barnes et al. (2025)

In a downturn, we can expect issuers to re-evaluate the cost-effectiveness of rewards schemes. We may see a shift towards more targeted, tiered, or usage-based incentives, potentially favouring higher-income or low-risk customers who are more likely to repay in full. There could also be greater integration of alternative loyalty mechanisms—such as cashback for essential spending or partnerships with digital platforms—that provide more immediate value to consumers under financial stress.

At the same time, the competitive landscape for consumer credit is evolving rapidly. One growing threat to traditional credit card spending—particularly during a recession—is the rise of fintech platforms offering Buy Now, Pay Later (BNPL) services. These alternatives are often marketed as more transparent and flexible than revolving credit, and they appeal strongly to younger consumers who are wary of interest-bearing debt. As BNPL adoption increases, especially in sectors like e-commerce and travel, issuers may see a decline in transaction volume—a key lever for funding rewards through interchange fees. This shift could further challenge the viability of expansive rewards programmes, especially if economic headwinds lead consumers to favour lower-risk, short-term credit arrangements over conventional card use.

Furthermore, central banks and regulators may increase scrutiny of opaque reward structures, particularly if they contribute to household over-indebtedness. In Latin America, for example, we are already seeing efforts to rebalance financial inclusion with responsible lending, and this may inspire similar policy shifts in other markets.

In short, while rewards programmes are unlikely to disappear, their structure and accessibility may change considerably in a downturn. Their future will depend on how effectively they align with risk management priorities and changing consumer needs in a more fragile economic environment.

From Spaghetti to the Finternet: A Decade of Thinking About Payment Hub Futures

Over a decade ago, in 2014, Fabian Markert published a paper, while modest in its scope, it offered a clear-headed analysis of the tangle that plagued banks’ internal payment architectures. Writing at the height of SEPA implementation, Markert described a world in which banks had grown up with scattered, legacy-based systems—so-called “spaghetti” architectures—that were expensive to maintain and increasingly ill-suited to a competitive European payment environment. His solution was the payment hub: a centralised structure that would allow financial institutions to untangle their systems, improve operational efficiency, and remain competitive in a world where margins on traditional payments were shrinking.

Fast forward to 2024, and Agustín Carstens, together with Nandan Nilekani, has co-authored a far more ambitious proposal under the auspices of the Bank for International Settlements. In Finternet: The Financial System for the Future, the authors sketch a vision not simply of a better bank infrastructure, but of a wholesale reimagining of the financial system as a “Finternet”—a decentralised, interoperable ecosystem where financial actors, including central banks, commercial banks, fintechs and individuals, interact through tokenised, programmable digital infrastructures. Unified ledgers and embedded policy tools are at the heart of this new model, with a strong emphasis on user-centricity, inclusion, and seamless integration of digital financial services.

There is, of course, a significant difference in tone and scale. Markert was writing in the language of process efficiency and IT alignment—his audience was the operational leadership within banks. His was a managerial, almost surgical intervention to streamline and future-proof internal systems. Carstens and Nilekani, by contrast, offer a normative, policy-oriented framework aimed at central banks and public-sector stakeholders. Their concern is not just with improving what exists, but with enabling a leap forward—a system that is programmable, inclusive, and digitally native from the ground up.

And yet, beneath the surface, both proposals speak to a common concern: the limits of legacy infrastructure in a world that demands speed, reliability and adaptability. Both recognise that meaningful innovation in the payment space depends not only on new technologies but on rethinking governance structures and system design principles. Both are also motivated by external pressures—Markert by SEPA-induced competition and collapsing fee margins, Carstens by the urgent need to integrate digital public infrastructure with financial services.

In our own reflections here on the Cashless Society blog, we’ve long argued that innovation in payment systems often comes not from the glittering promises of new technology alone, but from the careful work of redesigning the systems that underpin them. Whether it’s the creation of India’s UPI, the rise of soft infrastructure like QR code standards, or the role of central banks in convening cross-border payment solutions, these developments suggest that architecture matters. What Markert and Carstens share, despite their distance in tone and ambition, is an understanding that how we design the plumbing of the financial system ultimately shapes who benefits from it.

It’s easy to get swept up in the grand vision of a Finternet. But perhaps its future success still depends on solving the very problem Markert diagnosed a decade ago: how to move from tangled wires to intelligent flows.

The Future of Crypto Assets: A Balanced Perspective

Recent discussions on the role of crypto assets in the global financial system have highlighted contrasting views. An article in La Vanguardia suggests that Latin America’s experiment with cryptocurrencies may be losing momentum, pointing to declining adoption and regulatory challenges. Meanwhile, a World Bank blog argues that crypto assets remain unsuitable for central bank reserves due to their volatility and lack of widespread trust.

While it may be premature to declare the end of crypto assets, as La Vanguardia implies, the World Bank’s stance carries weight. Cryptocurrencies are unlikely to achieve mainstream adoption in their current form, particularly until central bank digital currencies (CBDCs) become more prevalent. CBDCs could provide the stability and regulatory oversight that many crypto assets lack, potentially reshaping the digital finance landscape.

For now, the crypto market remains in a transitional phase—neither obsolete nor yet mature enough to replace traditional financial systems. The path forward will likely depend on how digital assets evolve alongside state-backed alternatives.

Diversification and Competition

🎙️ I had a great chat with Colleen A. Dunlavy about her book Small, Medium, Large on my channel within the New Books Network podcast. Dunlavy challenges the idea that mass production was the ‘natural’ path in the US and shows how, before that, product diversity was the norm.

The book does two key things:

It explains how standards are negotiated in business.

It gives visibility to medium-sized companies, which are often overshadowed by startups or corporate giants.

💡 Key points from the conversation:

+Scaling a business is a strategic decision, not an inevitable fate.

+Leadership requires flexibility.

+Organisational culture matters as much as efficiency.

📲 Listen to the full interview here: https://newbooksnetwork.com/small-medium-large

What do you think?
Do we underestimate the role of medium-sized companies today?
Is product diversification still key to strategy?
