Over 2,000 businesses, more than £1m in circulation, and international acclaim. It closed in 2021. Two systems built on the same idea are still running - one for 91 years.
This case has not yet been reviewed by anyone who was involved. If that was you, we would like to hear from you.
In September 2012 Bristol launched the largest city-wide local currency in the UK. The Bristol Pound was backed one-to-one by sterling, administered jointly by a Community Interest Company and the Bristol Credit Union, and accepted by more than 2,000 independent businesses. You could pay some local taxes with it. The mayor took his salary in it. At its peak in 2016 over £1 million was in circulation, and the scheme was cited internationally as a model of local economic resilience.
The logic was easy to follow. Money that can only be spent locally stays local longer. Independent businesses gain ground against chains. Less value leaks out of the city to distant shareholders and payment processors.
It was not a naive idea. Complementary currencies have a long and serious history, and at least two of them have outlasted Bristol's by decades.
The digital scheme closed in August 2020. The paper notes were withdrawn in September 2021. The organisation was wound up in December 2023, after a successor project failed to secure funding of its own.
The most useful account of why comes from the people who ran it. A 2025 academic retrospective co-authored by the scheme's last managing director sets out the finances: over £1.2 million raised across eight years, roughly 13% from Bristol City Council, 5% from central government, 24% from the EU and 58% from trusts and foundations. Almost none of it went to running the currency itself, which was nonetheless being kept alive by it. The authors name the absence of an independent revenue stream as the single most significant cause of failure, and calculate that the currency would have needed 50 to 100 times its actual usage to sustain itself.
Annual council funding of at least £50,000 ended after the 2017/18 financial year. Usage had already been falling: the share of members who had used the currency in the previous twelve months dropped from 44% in August 2016 to under 33% by August 2020.
Two further findings are worth stating plainly. Only about 0.02% of Bristol's population ever used the currency, and roughly 80% of those who did held a degree, many in management roles. And the former managing director has named the organisation's own early tone as a barrier - communications she describes as strident and sometimes judgemental, later confirmed in the published retrospective as an exclusionary hurdle that was not recognised as one at the time.
Meanwhile the technology aged. The SMS-based payment method looked modern in 2012 and slow by 2016, after Apple Pay brought contactless payment to every phone. Businesses that had joined expecting more turnover generally did not get it, while dealing with staff training, slower checkouts and reconciliation. They left. That made balances harder to spend, which pushed individual usage down further.
Bristol was not alone. Comparable currencies in Totnes, Stroud and Exeter closed in the same decade. The last one, in Lewes, closed in 2025.
Two systems built on the same underlying idea are still running.
The WIR Bank was founded in Basel in 1934, in the depths of the Depression, to counter businesses hoarding cash. It obtained a Swiss banking licence in 1936. Today it serves more than 50,000 small and medium businesses, around 17% of all Swiss firms, across nine branches. Ninety-one years.
Sardex was founded in Sardinia in 2009 by five unemployed graduates, none of them economists, explicitly modelled on WIR. It now has over 4,000 member firms and an annual trade volume of €40 to 50 million.
Three differences explain almost everything.
They are business to business. Neither system asks a consumer to pay differently in a shop. Firms trade with firms that already invoice each other. Bristol competed against free contactless payment for everyday convenience, and lost.
They earn their keep. WIR takes transaction fees, mortgage charges and interest on the credit it issues. Sardex charges membership and employs paid Community Trade Advisors who actively broker trades between members. Neither depends on grant cycles.
They are most useful when things are worst. Research on WIR shows turnover rises in a recession, because the currency substitutes for liquidity that is genuinely missing. Bristol offered a moral benefit that was never urgent.
And Sardex proves this is not Swiss exceptionalism: it is a successful transfer of the WIR idea to a very different region. Its co-founder Giuseppe Littera is blunt that a one-to-one copy does not work, and that context-specific solutions have to be found case by case. WIR itself was a transfer - its founders travelled to Denmark twice in 1934 to study a clearing system there.
Three attempts at one idea. The two that survived were built so that using them was the easier option. The one that failed was built so that using it was the better one.
Who is it for - people or businesses? Consumer schemes compete with the payment method already in everyone's pocket. Business schemes compete with an invoice that takes sixty days to be paid.
Where does the operating money come from in year five? Not the launch grant. The recurring income. If the honest answer is "another grant", you have Bristol's problem before you have started.
Is it more useful in bad times or good? A system people reach for when money is tight has a future. One that depends on goodwill has a good decade at best.
Who is currently excluded, and would you notice? Bristol's users were overwhelmingly graduates. Nobody set out to build that, and nobody caught it in time.
No practitioner from this case is available to talk yet. We are working on it.
