Does Paying Cash Help the Economy?

There is a popular argument that paying by card erodes value in a way that cash does not. The version of the story you hear goes something like this. You pay £50 to the baker. The baker uses the same £50 to pay his flour supplier. The flour supplier pays his miller. The miller pays the farmer. The same £50 changes hands several times, generating five purchases out of one note, all without anyone losing anything. Now run the same chain with cards. Each transaction costs the merchant a percentage in card fees. After ten transactions at 1.5% each, the original £50 has been reduced to around £43 of net receipts. Value, the argument goes, has been silently erased.

It is a compelling story. It has a kernel of truth. It also misunderstands what is actually happening in both cases.

This post takes the argument seriously, walks through what is and is not true about it, and ends up somewhere more useful than the standard answer either way. The short version: card fees are real, but they do not destroy value, they redistribute it. Cash has its own costs that the original framing conveniently omits. And the more interesting argument behind both is not really about payment methods at all. It is about who captures the spread between what consumers spend and what producers receive.

If you have ever wondered whether paying cash is actually doing your local economy a favour, this is the long version of the answer.

The argument, as people actually make it

The cash-versus-card argument has a popular version and a sophisticated version. The popular version is the one you see on social media, in articles supporting cash mob campaigns, and in the framing of various lobby groups for cash use. It runs roughly as follows.

• Cash is debt-free settled money. The transaction completes the moment notes change hands.
• Card payments involve a chain of intermediaries (issuer bank, scheme, acquirer, acquirer bank), each taking a slice.
• The fees are extracted from the merchant, who has to charge more or accept lower margins to absorb them.
• Over a chain of transactions, the cumulative effect is that money leaks from the local economy into the global financial-services industry.
• Therefore, paying cash supports your local economy in a way that cards do not.

The more sophisticated version adds nuance about velocity (the speed at which money changes hands) and the role of small businesses (for whom card fees can be punitive on tight margins), and is harder to dismiss. We will return to it. The popular version is more common and worth addressing first.

The kernel of truth: card fees are real

To deny that card fees exist would be silly. In the UK, the headline rate for a typical small-merchant consumer-card transaction sits somewhere between 1 and 3 percent, depending on card type, transaction volume, and the merchant's acquirer agreement. The structure has three main components.

Interchange. Paid by the merchant's acquirer to the cardholder's issuing bank. Capped by EU and UK regulation at 0.2 percent for debit and 0.3 percent for credit on consumer cards, with looser rules for commercial cards.

Scheme fees. Paid to Visa or Mastercard for processing through their network. Smaller than interchange historically, but rising over recent years.

Acquirer markup. The merchant's payment processor takes a cut on top of interchange and scheme fees. This is where most of the variability in headline rates lives.

For a small UK café running, say, £200,000 a year through card terminals at a 1.7 percent blended rate, the annual card fee bill is around £3,400. That is real money. It is money the café would, in principle, prefer to keep. The fee is not nothing.

The same logic compounds across business-to-business chains, although most B2B transactions in the UK use bank transfers (Faster Payments, free or near-free), not card schemes. Where business chains use commercial cards, the percentages are higher and the cumulative effect of multiple links can become meaningful.

This much is consistent with the popular argument. The fees exist. They are paid by merchants. They are not refunded.

The fees do not destroy value. They redistribute it.

This is where the popular argument starts to come apart.

Money that goes to card processors does not vanish from the economy. It goes to Visa, Mastercard, the issuing banks, the acquirers, and onward to those companies' employees, contractors, shareholders, suppliers and the tax authorities. Those entities then spend the money on offices, salaries, technology, dividends and HMRC. The money keeps circulating.

The value-erosion framing implicitly treats card fees as if they were thrown into a fire. They are not. They are a transfer from one part of the economy (merchants and consumers) to another part (payment networks and banks). Whether you consider this transfer good, neutral or bad depends on what you think about the recipients. It is not destruction.

This is the same distinction that applies to any intermediary. A supermarket's margin is a transfer from farmer to retailer, not a destruction of value. A retailer's rent is a transfer from retailer to landlord, not destruction. A solicitor's fee is a transfer from client to legal profession, not destruction. None of these are obviously bad even though all of them involve someone else taking a cut.

The interesting question is whether the transfer to payment networks is efficient (are they providing services worth what they charge?) and whether the market is competitive (could a different structure deliver the same services for less?). Both of those questions are worth asking. They are not the same question as is value being destroyed.

The same critique applies to the velocity-chain version of the argument. Yes, if the same £50 cash note changes hands ten times, that is £500 of transactions with no card fees. But the £1.50 in card fees on each of those ten hypothetical card transactions also gets spent. The acquirer's staff buys lunch. The issuer's investors pay rent. The scheme's tax bill funds public services. The total amount of money circulating in the economy does not actually depend on the payment method. Only the distribution of who gets it does.

Cash isn't free either

The popular argument also assumes, implicitly, that cash is costless. It is not.

Central banks and academic researchers have studied the merchant cost of cash extensively. The Bank of England, the European Central Bank, the Bundesbank, the Reserve Bank of Australia and several Scandinavian central banks have all published cost-of-cash studies over the past two decades. The headline finding, with regional variations, is that the merchant cost of cash typically runs between 0.5 and 1.5 percent of cash turnover, sometimes more, and is often comparable to or higher than the cost of cards for the same merchant.

The costs come from several places.

Counting and reconciliation. Staff time spent counting tills at opening and closing, reconciling against transaction logs, finding discrepancies. Larger cash volumes mean larger discrepancies and more time finding them.

Float. Cash sitting in the till is working capital that is not earning interest, paying suppliers or reducing borrowing.

Banking. Many UK business bank accounts now charge significant fees for cash deposits, particularly for note volumes. Depositing £10,000 a week in cash can cost more in bank fees than the same value through card receipts.

Security. Theft (external and internal), robbery, cash-in-transit services, safes, insurance. Cash-in-transit alone costs UK retailers tens of millions of pounds a year industry-wide.

Counterfeit risk. Estimated at low single-digit basis points but non-zero, especially for higher-denomination notes.

Shrinkage. Cash businesses report higher rates of unexplained losses than card-only ones, in part because cash transactions are harder to audit and easier to misappropriate.

Time at the till. Cash transactions are slower than contactless cards (typically three to five seconds longer per transaction, in studies). For high-volume retailers, that time has a queueing cost.

Add it all up and the merchant cost of cash, properly accounted, is rarely zero and often higher than the equivalent card cost. The Bundesbank's headline finding in their cost-of-cash work has been that, on average, German merchants found cash slightly more expensive per transaction than cards once all hidden costs were included.

This is awkward for the popular argument. If cash has its own costs and those costs are comparable to card fees, then the value-erosion angle is not really about payment methods at all. It is about which intermediaries you prefer (banks and security firms versus card networks). Either way, intermediaries are getting paid. The question is just who.

The velocity argument

The most sophisticated version of the cash-versus-card argument leans on the concept of monetary velocity. Velocity is the rate at which money changes hands within an economy over time. Higher velocity means the same nominal money supply funds more transactions.

The argument runs: a £50 cash note that changes hands ten times in a day generates £500 of economic activity at no marginal cost. A £50 card transaction that compounds through ten merchants generates the same £500 of activity but with cumulative fees of perhaps £75. The cash chain is more efficient in transaction-per-pound terms.

There is a real point here. For chains of small-margin transactions in tight-margin sectors (independent cafés, market stalls, small restaurants), card fees can compound enough to matter to the bottom line. This is the sense in which the popular argument has the strongest defence.

But the velocity argument also has problems.

The first problem is empirical. The velocity of money in modern developed economies has been falling for decades, regardless of payment method. The shift from cash to cards has not been the dominant driver. Other factors (changes in banking, savings behaviour, demographics, interest rates, inflation expectations) are doing most of the work. Blaming velocity decline on cards specifically is not supported by the data.

The second problem is that card payments may enable transactions that cash does not. Online sales, larger transactions, faster checkout, no need to find an ATM. The increase in transaction volume from cards arguably more than offsets the per-transaction fee drag. The total amount of economic activity is not obviously lower with cards than without.

The third problem is that most business-to-business transactions in the UK and EU happen by bank transfer, not by card. SEPA Credit Transfer (in the EU) and Faster Payments (in the UK) are effectively free for businesses. The card-fee chain only really compounds at the consumer-facing end. Once the baker pays his supplier, the transaction usually goes via bank transfer, not card, and the fee chain breaks.

The velocity argument has substance but is narrower than it sounds. It applies most cleanly to the very small subset of transactions that happen in cash-to-card-to-card-to-card chains at consumer prices, and even there, the cost-of-cash counter applies in parallel.

Where the real argument lives

If the value-erosion framing is mostly wrong, is there a legitimate concern at the heart of the cash-versus-card debate? There are several, actually.

Market structure. Visa and Mastercard control the vast majority of card payments globally. They operate as a near-duopoly. Pricing power in any near-duopoly tends to drift upward over time unless regulation or competition pulls it back. The UK Payment Systems Regulator and the European Commission have both investigated and intervened on card pricing repeatedly because the market structure does not naturally generate competitive outcomes. This is a real political-economic concern, and it is the legitimate version of the money-is-leaking argument. It is not about destruction. It is about market power and rent extraction.

Financial inclusion. Some people cannot easily use cards. Older people, people without bank accounts, people fleeing domestic violence, undocumented workers, people with cognitive impairments. A fully card-only economy excludes them. The UK Access to Cash Review (2019), led by Natalie Ceeney, made this argument carefully and led to legislative protection of cash infrastructure.

Privacy and surveillance. Card payments are observable to issuers, schemes, and, with appropriate process, to governments. Cash is not. People who care about not being trackable as a matter of principle have legitimate reasons to prefer cash for some purchases.

Resilience. Various card system outages in recent years have illustrated what happens when card infrastructure goes down: shops cannot trade. Cash provides a fallback. A purely card-based economy has a single point of failure that does not exist in a mixed economy.

Monetary sovereignty. Cash is a liability of the central bank. Card payments depend on commercial bank money. There is a real technical argument, made by central bankers themselves in discussions of central bank digital currencies, that retail use of central-bank-issued money is part of monetary sovereignty.

None of these arguments are about value destruction. They are about market power, inclusion, privacy, resilience and sovereignty. They are good arguments. They support a continued role for cash. They do not support the popular framing of cards erode value. They support a different and stronger framing.

What this means for you at the till

The honest answer for an individual deciding how to pay at the till is: it mostly does not matter for value-creation reasons. The baker is fine either way. Your spending lands in his account whether the route is via interchange or via a paper note in the till.

What does matter, occasionally, is the merchant's stated preference. Some merchants, particularly small ones running on tight margins, genuinely prefer cash for the fee saving (net of cash-handling cost). If a small café has a sign asking for cash on small purchases, paying cash is a small kindness. If a chain supermarket has no preference, it does not matter.

If you are deciding for political-economic reasons, the legitimate arguments are the ones in the previous section. Card networks are a near-duopoly extracting rents from the economy. You may decide that is bad enough to want to vote with your wallet by preferring cash where practical. That is a coherent position, and you do not need the misleading value-erosion framing to support it. The structural argument is stronger than the popular one.

If you are deciding for personal-finance reasons, your decision should probably be about how the choice affects you, not the wider economy. Cards give you a record of every transaction (useful for budgeting), reward points (if you are disciplined about credit), payment protections under Section 75 in the UK (for credit cards over £100), and the ability to dispute fraudulent transactions. Cash gives you a tactile sense of the money leaving your hand (useful for resisting impulse buys), no transaction record (useful or not, depending on what you value), and zero risk of compromised data. The genuinely interesting personal-finance question is not which payment method preserves value (neither does, both transfer it) but which one helps you spend in a way that matches what you actually want. (See The True Cost of Everything You Buy for the broader version of this question.)

How Endute fits in

There is one place where the cash-versus-card question intersects directly with personal finance, and that is the cost of payment methods to you rather than to the merchant.

The headline card fee in the popular argument is the merchant fee. The merchant pays it, not you. But there are several card-related fees that do come out of your account: foreign-exchange margins on overseas spending (often 2 to 4 percent over the interbank rate), ATM withdrawal fees on some networks (£1 to £3 per pull), cash-advance fees on credit cards (typically 3 to 5 percent plus immediate interest), and dynamic currency conversion at foreign tills (a 4 to 8 percent premium over the network rate). These are quietly significant and usually invisible unless you go looking.

Endute is an all-in-one personal finance app that imports your transactions, categorises them, and surfaces the costs you would otherwise miss. Endute supports more than 18,000 banks across the EU, UK, CA, and US.

Multi-currency transactions show both amounts. Foreign purchases display both the native currency and the converted amount, so the FX margin is visible if you compare the rate against the published interbank rate that day. The difference is your effective conversion cost.

ATM withdrawals appear as line items. Cash withdrawals come in as transactions you can categorise and total. If you pulled £200 from an ATM with a £2.50 fee, the fee appears separately and your annual ATM-fee total surfaces in your Spending by Category report.

Spending by Category over time. Card-related fees, ATM fees and currency conversion costs can be grouped into a single category. Over a year, the cumulative total often surprises people. A travel-heavy consumer can easily be paying £200 to £500 a year in FX margins alone without noticing any individual transaction.

Subscriptions and bills tracker. Some card-related fees (account maintenance, premium card subscription fees) are recurring. The tracker surfaces them with annualised totals so you can decide whether the card is actually paying back its costs.

The popular cash-versus-card argument is not really your problem. The hidden card fees that are your problem are the ones the argument never mentions.

The closing

The popular version of the cash-versus-card argument is wrong about its central claim. Card fees do not destroy value. They redistribute it from merchants to payment networks. Cash has comparable hidden costs that the argument conveniently leaves out.

The sophisticated version of the argument is partially right but narrower than it sounds. The velocity-of-money case applies most cleanly to small chains of consumer-priced transactions in tight-margin sectors, and even there it competes with the cost of cash. Most of the economy is not actually card-fee-sensitive in the way the argument requires.

The real arguments for cash, the ones worth caring about, are about market power, financial inclusion, privacy, resilience and monetary sovereignty. They are stronger than the value-erosion claim. They do not need the value-erosion claim to stand on their own.

Pay how you want. The economy will be fine either way. Just do not let anyone convince you that swiping your card is silently dismantling local commerce. It isn't. It is just paying a tax to a different intermediary than the bank, the security firm and the cash-in-transit van.

If you object to that, object to it directly. The structural argument is the one that holds water. The value-erosion argument leaks.
