It's lunchtime at Glasgow Chambers in late November, and Councillor George Redmond is getting worked up at the prospect a Glasgow Pound. "We would be Glasgow-centric about it," he says conspiratorially, as though there is any other way to be. "Can you imagine having the face of Billy Connolly on our local currency? Or Alex Ferguson, or Kenny Dalglish?" The pound has been trading at its lowest level since 1985 since the UK voted to leave the European Union and there are fears that it could dip further as Brexit ensues. Timebanks, local exchange trading systems (LETS) and digital inventions like bitcoin can provide alternative ways for people to pay for goods and services when mainstream currencies hit crises. But they will only work if Britons are ready to accept that they have the power to invent their own currency. "At the moment, if the pound stops working for us, the whole economy grinds to a halt because there aren't alternatives," Duncan McCann, a researcher at the New Economics Foundation, tells those gathered in a gilded room at Glasgow Chambers to discuss the Glasgow Pound. McCann is a long-time advocate of alternative means of exchange. He is behind the ScotPound, a proposal for a new national currency for Scotland that emerged after the referendum on Scottish independence. It's an idea he no longer thinks will work, because the debate, since Brexit, has shifted from the currency issue back to ideas about Scottish independence. Today, he's preaching to the converted. Alex Walker, the chairman of the 250-person Ekopia community in Northern Scotland, listens at the back. The Eko has been the main means of buying everything from beer to bananas in Ekopia since Walker founded it 20 years ago. On an adjacent table, Tracy Duff, a community learning and development worker from Clackmannanshire Council, digs out some papers. She runs the Clacks Youth Timebank, a scheme where 12- to 15-year-olds can earn credit for volunteering. Taking notes up front is Ailie Rutherford, one of the people who organised the meeting. Rutherford runs the People's Bank of Govanhill, a currency that changes value depending on the income of the user. "I don't see any reason why we shouldn't invent our own currency and play with it," she says. Everyone has gathered to decide what a Glasgow Pound might look like at a time when many are asking if local currencies can work at all. Councillor Redmond says Glasgow has been closely watching existing alternative currencies like the Brixton Pound in London, which was introduced in 2011. In Britain, there are now schemes in Totnes, Lewes, Brixton, Bristol and Exeter. Hull has its own local digital currency that can be earned from volunteering and used to pay council tax. Kingston, Birmingham and Liverpool have schemes underway. Glasgow could be next. But the working group has some serious questions to answer first, not least: do complementary currencies actually work? "People don't understand money," Molly Scott Cato, Green MEP for the South West of England and Gibraltar, says over the phone. Scott Cato says the fish-in-water problem – the idea that sterling is so ubiquitous, it is never questioned – is the biggest challenge for complementary currencies. She knows all about it as a founder of the Stroud Pound in 2010, a currency that has since gone out of circulation. The Bristol Pound (£B) entered into circulation in September 2012. By June 2015, 1m £B had been issued, with £B700,000 of that still in circulation. In a population of some 450,000 people, that's the equivalent of each Bristolian carrying less than £B2 in change in their pocket. "The small scale is a problem and a strength," says Stephen Clarke, chief financial officer of the Bristol Pound. "The benefit comes from the fact that local currencies are trusted organisations: we're a Community Interest Company limited by guarantee." That means assets owned by the the Bristol Pound have to be used for the good of the community, rather than purely for profit. Without enough currency in circulation, it ceases to work. Scott-Cato says Stroud's size meant meant the Stroud Pound was never viable: "We couldn't get the velocity of circulation right, which contrasts with the Bristol Pound." Clarke also says the small scale of local currencies means they are "always scrabbling around looking for money". One way founders of the Bristol Pound have addressed his is by setting up an umbrella organisation, the Guild of Independent Currencies, to share information between local currencies in the UK and help new organisations. "At the moment we're all reinventing the wheel every time," Clarke says. Technology might also have a solution. Peter Ferry, a commercial director, travels to Glasgow to tell those working on the Glasgow Pound that that his company Wallet has come up with a way to use the blockchain, the technology behind bitcoin, to make it easier for people to use multiple types of currency. "There might be many currencies around the country that people want to use. We need to make it simple for them to do that and also to make it simple to earn these currencies in many ways," he says. "Bristol is seen as a quirky, individualistic kind of place," Clarke says. "When we first produced the Bristol Pound note, people were really proud of it. It got through to people not just sat around coffee shops. I'm not sure a London Pound would work, because people identify with their local area in London rather than the city as a whole." Bristol Pound users don't have high incomes necessarily, but surveys show they are engaged with their local community and they have a higher educational attainment than average. In the years since the financial crisis, as local authority budgets have shrunk, some areas have relied heavily on engaged communities to fill in gaps in public services. By contrast, deprived areas where people cannot afford time and money to put into their community have become more deprived, making them even harder for local currencies to reach. "It is difficult to get into more disadvantaged areas," Stephen Clarke says. "We have a ten-year life expectancy gap between different parts of the city. When you go to disadvantaged areas with the Bristol Pound hat on you realise there aren't independent shops there, there's an Aldi and Lidl and that's it." When Scott-Cato and her colleagues wrote about the experience of setting up the Stroud Pound, they said it was telling that complementary currencies have been accused of being a game for middle-class people, rather than a genuine economic solution. Ciaran Mundy, CEO of the Bristol Pound, says it is important to think of the systemic impact rather than looking for targeted treatment of symptoms of economic deprivation. "Poverty has many causes," he says. "One of these is how the economy is structured in terms of how money flows out of poor areas due to high dependence on larger national and international companies paying lower wages and using offshore accounts to hide the money from the tax man." Every time a Brixton Pound transaction is made, 1.5 per cent goes into a Brixton Fund. This is used to give micro-grants of between a few hundred and £2000 to local projects and community groups. "We aim to target projects that aren't large enough to apply for more formal grant funding," says Lucy Çava, project manager at the Brixton Pound. Meanwhile, the people behind the Bristol Pound are readying a mutual credit network called Bristol Prospects. Through this network, businesses in Bristol can exchange credit in the form of loans that are neutralised within the network, helping one another to grow without relying on the high rates of commercial lenders. "We know from research that a number of small businesses in Bristol are struggling to get money on reasonable terms," says Clarke, "and that banks are not interested in smaller loans to businesses. So we think there is a strength in the Bristol Pound network to start something like this that is linked, but separate."
