Europeans hand over banknotes for barely half their shop purchases now — down from four in five a decade ago. And yet there has never been more cash in existence. The till emptied. The drawer filled. This is the paradox of banknotes, and in 2026 governments started legislating it back into daily life.
€1,588 BN
Value of euro banknotes in circulation, 31 Dec 2024 — an all-time high, up 41% since 2016.
Over the same nine years, cash’s share of euro-area shop payments fell from 79% to 52%. Sources: ECB banknote circulation statistics; ECB SPACE 2024.
01 / The two lines
One line falls. The other climbs.
These are the same currency over the same years. On the left, how often people reach for notes at a till. On the right, how many notes exist. Nothing about the first line explains the second.

52%
Of shop payments, by number
Down from 59% in 2022 and 72% in 2019. Cash is still the single most-used method at the till in 14 of 20 euro-area countries.
39%
Of shop payments, by value
Cards passed cash by value at 45%. Notes now mostly settle the small stuff — the coffee, the market stall, the bus.

Say cash must stay an option
An increasing majority of euro-area consumers call having the cash option important or very important — even as they use it less.
02 / The spectrum
A continent with two habits.
Europe shares a currency but not a reflex. Across the euro area in 2024, the share of in-store payments made in cash ran from roughly one in five to two in three — a threefold spread inside a single monetary union.

03 / The denominations
The money we spend is not the money we keep.
The clearest fingerprint of hoarding is denomination. Americans make 14% of their payments in cash and carry about $69 in a wallet — yet four-fifths of all dollars in circulation sit in $100 bills, and roughly half the dollar stock lives outside the United States entirely.

04 / The stakes
On 28 April 2025, the terminals went dark.
At 12:33 CEST, the Iberian grid lost about 15 gigawatts in five seconds. Power failed across mainland Portugal and peninsular Spain for roughly ten hours. Card readers stopped. ATMs stopped. Phones stopped. For most of a day, the only money that worked was the money already in people’s pockets.

05 / The reversal
The most cashless country in the world just made cash compulsory.
Sweden spent two decades engineering physical money out of ordinary life — only 5% of Swedes used cash for their most recent in-store purchase, against 2% in Norway. Then the argument changed from convenience to resilience, and the law changed with it.
1 JUL 2026
Swedish cash-acceptance law in force
With limited exceptions, grocery stores and pharmacies must now accept cash, and banks carry a clearer duty to keep deposit facilities available nationwide. The Riksbank backed the change on two grounds: inclusion and preparedness.

Sweden vs Norway · last in-store purchase paid in cash
Sweden and Norway hold the lowest cash-in-circulation-to-GDP ratios in the world. The reversal is not about demand for cash as a payment method. It is about what happens when the alternative fails.
Why it matters
A payment system with one leg is a payment system that can trip.
The paradox is the point. People are not hoarding banknotes because they love shopping with them. They are holding value in a form that works with no power, no signal, no bank, and no counterparty — and that demand shows up as a record note stock even as till use collapses.
Cash is infrastructure, and infrastructure decays quietly. When ATMs, bank branches and cash-handling shops close because volumes fell, the option disappears before anyone votes on it. That is why the Riksbank is now legislating access rather than assuming it.
Keep a small physical reserve. The Netherlands, Austria and Finland suggest €70–100 per person; Sweden suggests SEK 1,000 per adult; the European Commission frames it as 72 hours of essentials. Small notes are more useful than large ones when no one can make change.
Pay in cash occasionally, deliberately. Acceptance is a use-it-or-lose-it network. Every cash transaction is a small vote to keep the second rail maintained — and it keeps the roughly one-in-five adults who rely on it able to buy food.
