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.

We still have time to change our minds on Brexit

The British people will soon find they have been misled. 

On the radio on 29 March 2017, another "independence day" for rejoicing Brexiteers, former SNP leader Alex Salmond and former Ukip leader Nigel Farage battled hard over the ramifications of Brexit. Here are two people who could be responsible for the break-up of the United Kingdom. Farage said it was a day we were getting our country back.

Yet let alone getting our country back, we could be losing our country. And what is so frustrating is that not only have we always had our country by being part of the European Union, but we have had the best of both worlds.

It is Philip Hammond who said: “We cannot cherry pick, we cannot have our cake and eat it too”. The irony is that we have had our cake and eaten it, too.

We are not in Schengen, we are not in the euro and we make the laws that affect our daily lives in Westminster – not in Europe – be it our taxes, be it our planning laws, be it business rates, be it tax credits, be it benefits or welfare, be it healthcare. We measure our roads in miles because we choose to and we pour our beer in pints because we choose to. We have not been part of any move towards further integration and an EU super-state, let alone the EU army.

Since the formation of the EU, Britain has had the highest cumulative GDP growth of any country in the EU – 62 per cent, compared with Germany at 35 per cent. We have done well out of being part of the EU. What we have embarked on in the form of Brexit is utter folly.

The triggering of Article 50 now is a self-imposed deadline by the Prime Minister for purely political reasons. She wants to fix the two-year process to end by March 2019 well in time to go into the election in 2020, with the negotiations completed.

There is nothing more or less to this timing. People need to wake up to this. Why else would she trigger Article 50 before the French and German elections, when we know Europe’s attention will be elsewhere?

We are going to waste six months of those two years, all because Prime Minister Theresa May hopes the negotiations are complete before her term comes to an end. I can guarantee that the British people will soon become aware of this plot. The Emperor has no clothes.

Reading through the letter that has been delivered to the EU and listening to the Prime Minister’s statement in Parliament today amounted to reading and listening to pure platitudes and, quite frankly, hot air. It recalls the meaningless phrase, "Brexit means Brexit".

What the letter and the statement very clearly outlined is how complex the negotiations are going to be over the next two years. In fact, they admit that it is unlikely that they are going to be able to conclude negotiations within the two-year period set aside.

That is not the only way in which the British people have been misled. The Conservative party manifesto clearly stated that staying in the single market was a priority. Now the Prime Minister has very clearly stated in her Lancaster House speech, and in Parliament on 29 March that we are not going to be staying in the single market.

Had the British people been told this by the Leave campaign, I can guarantee many people would not have voted to leave.

Had British businesses been consulted, British businesses unanimously – small, medium and large – would have said they appreciate and benefit from the single market, the free movement of goods and services, the movement of people, the three million people from the EU that work in the UK, who we need. We have an unemployment rate of under 5 per cent – what would we do without these 3m people?

Furthermore, this country is one of the leaders in the world in financial services, which benefits from being able to operate freely in the European Union and our businesses benefit from that as a result. We benefit from exporting, tariff-free, to every EU country. That is now in jeopardy as well.

The Prime Minister’s letter to the EU talks with bravado about our demands for a fair negotiation, when we in Britain are in the very weakest position to negotiate. We are just one country up against 27 countries, the European Commission and the European Council and the European Parliament. India, the US and the rest of the world do not want us to leave the European Union.

The Prime Minister’s letter of notice already talks of transitional deals beyond the two years. No country, no business and no economy likes uncertainty for such a prolonged period. This letter not just prolongs but accentuates the uncertainty that the UK is going to face in the coming years.

Britain is one of the three largest recipients of inward investment in the world and our economy depends on inward investment. Since the referendum, the pound has fallen 20 per cent. That is a clear signal from the world, saying, "We do not like this uncertainty and we do not like Brexit."

Though the Prime Minister said there is it no turning back, if we come to our senses we will not leave the EU. Article 50 is revocable. At any time from today we can decide we want to stay on.

That is for the benefit of the British economy, for keeping the United Kingdom "United", and for Europe as a whole – let alone the global economy.
