Why Japan needs Abenomics and Bitcoin faces a lost century

What do Japan's "lost decade" and the intractable problem facing bitcoin have in common? Deflation.

The Japanese economy is in a mess. It has been for a while now. GDP broke $5trn in 1996, but then fell, and stayed low for a decade and a half. It only reached that high again in 2011, after well over a decade with growth fluctuating between mildly positive and mildly negative : the "lost decade" of economists' nightmares.

That's the background against which the new prime minister Shinzo Abe is struggling. Abe, a right-wing popular nationalist, was elected on a platform of giving the Bank of Japan a kick up the arse and using unconventional methods to restore the country to growth. His motivations have been questioned repeatedly: some fear that he's just trying to provide a short term boost to the economy before the upcoming election to in country's upper house; others, that he's only enacting bold new policy due to a stubborn belief that whatever conventional economists say must be wrong. Sure, a stopped-clock is right twice a day, but that doesn't mean you want to base your economy on what it says.

But the unconventional policies have been enacted, and now we are just waiting to see their effect. Abe has launched a ¥10.3trn stimulus package; his economic minister has explicitly targeted the stock market, in an attempt to push it up by 17 per cent in just two months; and he's got his choice of central bank governor, with the appointment of the maverick Haruhiko Kuroda.

But if we want to find out whether these plans are working, we don't look at GDP. That's too slow to change, it's too subject to external shocks, and, most importantly, it's a symptom, not a cause.

The real culprit is inflation. Or rather, deflation.

The Japanese economy has had inflation hovering around 0 per cent – and more frequently below it than above it – for almost as long as it has had stagnation. And while the country has seen a return, of sorts, to GDP growth, inflation remains as stubbornly negative as ever. Even after Abe's reforms, the headline rate fell – down to -0.9 per cent, the fastest rate of deflation in three years. That's against a background, not only of all those impressively major reforms, but also a far more direct one: raising the inflation target of the bank of Japan from 1 to 2 per cent.

But why is deflation a problem? In the west we're used to fearing inflation, after the scarring experiences of the 1970s, when prices grew by 20 per cent in a year. And we all learned in school about hyperinflation in Weimar Germany, where the price of bread would be higher in the afternoon than it had been in the morning, and how that led to the rise of Hitler. (Incidentally, that connection is largely mythical; although it was responsible for prompting the creation of many extremist groups, hyperinflation was largely beaten by 1924, long before the Nazi party became a force in German politics.)

But deflation – prices getting lower year-on-year – sounds like a good thing. Who doesn't like getting richer without having to do anything?

The easiest way to explain the issues is to look at another economy which could almost have been invented to illustrate the problems with deflation: the trade in bitcoins.

Bitcoin, you may recall, is an anonymous, cryptographic, peer-to-peer digital currency. It's been in the news because of its astonishing boom-and-bust dynamics, with the value of one bitcoin increasing by 2000% in two months, then losing almost all of that in a week, and now slowly returning to a second high. But what's interesting here is that it's a currency with deflation built in from the very start.

There will only ever be 21 million bitcoins. Half of them have been made – "mined", in the parlance – already, and the rest will be released in decreasing quantity at ten minute intervals until 2140. Add in the fact that, although they can't be created in any other way, they can be destroyed just by deleting the file that holds them, and you've got a currency which is designed to deflate.

That deflation was made far worse in the last couple of months by the hyperbolic increase in the value of a bitcoin measured in any normal currency. If you can buy a bitcoin for $10, and then a month later it costs you $200, then that is largely inseparable from inflation, particularly since you still need to use real currency to eat, pay your rent, and buy your travelcard to get to work. It got so bad that some started talking about "hyperdeflation".

What all that deflation does is ensure that, if you hold bitcoins, it makes sense to wait until you're absolutely sure you need to make a purchase before you part with them. After all, if you're the guy who bought a pizza for 10,000 bitcoins in 2010, you may have got a tasty meal; but if you had held off, you would be $1.3m richer now.

And it gets worse when you look at things like investment. If you used bitcoins to buy equity in a startup, your expected return would have to be through the roof to even stand still compared to where you would expect to be if you hoarded the money.

These are hypothetical questions for bitcoin – no stock market in the world lets you buy equity with the currency yet – but they're very real problems in Japan. The dearth of investment is so bad that the government has "nationalised" industrial stock, spending up to ¥1trn to buy plants in its biggest manufacturing industries.

There is optimism that Japan can pull itself out of this hole. Even as inflation continues to fall, predictions for future inflation are high; and there's a certain sense that with enough wild plans thrown at the wall, something is going to stick. Even if its just out of the frying pan and into the fire, a change of scenario would be nice.

The future's not so rosy for bitcoin. Even if its price stabilises, the long-term policy of deflation is not going to go away. The fact that Japan's "lost decade" lasted fifteen years may seem like a stretch, but bitcoin's could last a lifetime.

Richmond is a victory for hope - now let's bring change across the country

The regressives are building their armies. 

Last night a regressive alliance was toppled. Despite being backed by both Ukip and the Conservative Party, Zac Goldsmith was rejected by the voters of Richmond Park.

Make no mistake, this result will rock the Conservative party – and in particularly dent their plans for a hard and painful Brexit. They may shrug off this vote in public, but their majority is thin and their management of the post-referendum process is becoming more chaotic by the day. This is a real moment, and those of us opposing their post-truth plans must seize it.

I’m really proud of the role that the Green party played in this election. Our local parties decided to show leadership by not standing this time and urging supporters to vote instead for the candidate that stood the best chance of winning for those of us that oppose Brexit. Greens’ votes could very well be "what made the difference" in this election (we received just over 3,500 votes in 2015 and Sarah Olney’s majority is 1,872) - though we’ll never know exactly where they went. Just as importantly though, I believe that the brave decision by the local Green party fundamentally changed the tone of the election.

When I went to Richmond last weekend, I met scores of people motivated to campaign for a "progressive alliance" because they recognised that something bigger than just one by election is at stake. We made a decision to demonstrate you can do politics differently, and I think we can fairly say that was vindicated. 

There are some already attacking me for helping get one more Liberal Democrat into Parliament. Let me be very clear: the Lib Dems' role in the Coalition was appalling – propping up a Conservative government hell bent on attacking our public services and overseeing a hike in child poverty. But Labour’s record of their last time in office isn't immune from criticism either – not just because of the illegal war in Iraq but also their introduction of tuition fees, privatisation of our health service and slavish worship of the City of London. They, like the Liberal Democrats, stood at the last election on an austerity manifesto. There is a reason that we remain different parties, but that doesn’t mean we shouldn't also seize opportunities like this to unite behind what we have in common. Olney is no perfect candidate but she has pledged to fight a hard Brexit, campaign against airport expansion and push for a fair voting system – surely progressives can agree that her win takes us forward rather than backwards?

Ultimately, last night was not just defeat of a regressive alliance but a victory for hope - a victory that's sorely needed on the back of of the division, loss and insecurity that seems to have marked much of the rest of this year. The truth is that getting to this point hasn’t been an easy process – and some people, including local Green party members have had criticisms which, as a democrat, I certainly take seriously. The old politics dies hard, and a new politics is not easy to forge in the short time we have. But standing still is not an option, nor is repeating the same mistakes of the past. The regressives are building their armies and we either make our alternative work or risk the left being out of power for a generation. 

With our NHS under sustained attack, our climate change laws threatened and the increasing risk of us becoming a tax haven floating on the edge of the Atlantic, the urgent need to think differently about how we win has never been greater. 

An anti-establishment wave is washing over Britain. History teaches us that can go one of two ways. For the many people who are utterly sick of politics as usual, perhaps the idea of politicians occasionally putting aside their differences for the good of the country is likely to appeal, and might help us rebuild trust among those who feel abandoned. So it's vital that we use this moment not just to talk among ourselves about how to work together but also as another spark to start doing things differently, in every community in Britain. That means listening to people, especially those who voted for Britain to leave the EU, hearing what they’re saying and working with them to affect change. Giving people real power, not just the illusion of it.

It means looking at ways to redistribute power and money in this country like never before, and knowing that a by-election in a leafy London suburb changes nothing for the vast majority of our country.

Today let us celebrate that the government's majority is smaller, and that people have voted for a candidate who used her victory speech to say that she would "stand up for an open, tolerant, united Britain".  But tomorrow let’s get started on something far bigger - because the new politics is not just about moments it's about movements, and it will only work if nobody is left behind.
