Facing the Grexit

Could Greece actually leave the Eurozone?

A big switch appears to have been flipped in the last week: talk of Greece exiting the Eurozone has moved from wild blue-sky thinking to the sort of thing Very Serious People write about. The Financial Times is running a series on how such an exit would happen, beginning today with a piece quoting several Eurozone central bankers saying things like:

I guess an amicable divorce – if that was ever needed – would be possible. (Luc Coene, central bank governor of Belgium)

And:

Technically, it [a Greek exit] can be managed… It is not necessarily fatal, but it is not attractive. (Patrick Honohan, Irish central bank governor)

Bloomberg echoed the statements, while Der Spiegel is running a cover that doesn't really need translating:

The macroeconomic issues with a Greek exit – a Grexit – would be immense. Paul Krugman lays out a convincing four-step guide as to how the whole thing could result in the end of the Eurozone, "and we’re talking about months, not years, for this to play out."

Krugman sees a Grexit leading to massive capital flight from Spain and Italy as savers race to move their deposits to Germany. That leads to either capital controls to prevent the exit, or massive (even in the context of those which have already happened) European Central Bank loans to stop the banking systems of those countries failing. Germany then has a choice. Either it becomes a guarantor for Spanish debt indefinitely, while also tolerating a higher level of Eurozone inflation than it has ever been willing to accept before; or the Eurozone breaks up.

Even the smaller issues with a Greek exit are hugely difficult to overcome, though. Currency swaps are normally done with huge levels of planning, and a long period of both currencies running in tandem to enable things like vending machines and electronic systems to switch over. But because the devaluing of a new Drachma would be so strong so quickly, Greece has no real chance to do this. If it decides to leave the Euro, it needs to get it over and done with in very little time.

Last September, Josh Hempton, a hedge fund manager, looked at the closest historical precedent for this high-speed currency swap: the break-up of the Austro-Hungarian Empire:

What they did was put troops on all the borders and made it illegal to take cash (or wire cash!) across borders. Then all Austro-Marks in each country was stamped - converted to Drachma for Greece, Marks for Germany, Peseta for Spain or whatever the currencies of the day were [If someone remembers the 1918 border splits better than me they are welcome to say...]

In this conception all Spanish debts become Peseta debts. All German debts become Mark debts. All Greek debts become Drachma debts. Unstamped currency goes worthless.

If you are going to split the currency I see no alternative to a big bang - and if you do that I see no alternative to troops at the border stopping transfers (and wire transfers) because shifting cash North looks so profitable against a sudden devaluation. Suddenly – and against all historic hope – its time again to guard the French-German (and every other European border) with troops for a week whilst the money is stamped.

Despite the fact that at every stage, the story of how the Eurozone will collapse is credible, there is a peculiar sense of optimism. As Joe Weisenthal writes, though, the thinking seems to be:

A crisis will be averted because to not avert it would be such a disaster. We'll see if that actually holds up.

The rise of the green mayor – Sadiq Khan and the politics of clean energy

At an event at Tate Modern, Sadiq Khan pledged to clean up London's act.

On Thursday night, deep in the bowls of Tate Modern’s turbine hall, London Mayor Sadiq Khan renewed his promise to make the capital a world leader in clean energy and air. Yet his focus was as much on people as power plants – in particular, the need for local authorities to lead where central governments will not.

Khan was there to introduce the screening of a new documentary, From the Ashes, about the demise of the American coal industry. As he noted, Britain continues to battle against the legacy of fossil fuels: “In London today we burn very little coal but we are facing new air pollution challenges brought about for different reasons." 

At a time when the world's leaders are struggling to keep international agreements on climate change afloat, what can mayors do? Khan has pledged to buy only hybrid and zero-emissions buses from next year, and is working towards London becoming a zero carbon city.

Khan has, of course, also gained heroic status for being a bête noire of climate-change-denier-in-chief Donald Trump. On the US president's withdrawal from the Paris Agreement, Khan quipped: “If only he had withdrawn from Twitter.” He had more favourable things to say about the former mayor of New York and climate change activist Michael Bloomberg, who Khan said hailed from “the second greatest city in the world.”

Yet behind his humour was a serious point. Local authorities are having to pick up where both countries' central governments are leaving a void – in improving our air and supporting renewable technology and jobs. Most concerning of all, perhaps, is the way that interest groups representing business are slashing away at the regulations which protect public health, and claiming it as a virtue.

In the UK, documents leaked to Greenpeace’s energy desk show that a government-backed initiative considered proposals for reducing EU rules on fire-safety on the very day of the Grenfell Tower fire. The director of this Red Tape Initiative, Nick Tyrone, told the Guardian that these proposals were rejected. Yet government attempts to water down other EU regulations, such as the energy efficiency directive, still stand.

In America, this blame-game is even more highly charged. Republicans have sworn to replace what they describe as Obama’s “war on coal” with a war on regulation. “I am taking historic steps to lift the restrictions on American energy, to reverse government intrusion, and to cancel job-killing regulations,” Trump announced in March. While he has vowed “to promote clean air and clear water,” he has almost simultaneously signed an order to unravel the Clean Water Rule.

This rhetoric is hurting the very people it claims to protect: miners. From the Ashes shows the many ways that the industry harms wider public health, from water contamination, to air pollution. It also makes a strong case that the American coal industry is in terminal decline, regardless of possibile interventions from government or carbon capture.

Charities like Bloomberg can only do so much to pick up the pieces. The foundation, which helped fund the film, now not only helps support job training programs in coal communities after the Trump administration pulled their funding, but in recent weeks it also promised $15m to UN efforts to tackle climate change – again to help cover Trump's withdrawal from Paris Agreement. “I'm a bit worried about how many cards we're going to have to keep adding to the end of the film”, joked Antha Williams, a Bloomberg representative at the screening, with gallows humour.

Hope also lies with local governments and mayors. The publication of the mayor’s own environment strategy is coming “soon”. Speaking in panel discussion after the film, his deputy mayor for environment and energy, Shirley Rodrigues, described the move to a cleaner future as "an inevitable transition".

Confronting the troubled legacies of our fossil fuel past will not be easy. "We have our own experiences here of our coal mining communities being devastated by the closure of their mines," said Khan. But clean air begins with clean politics; maintaining old ways at the price of health is not one any government must pay. 

'From The Ashes' will premiere on National Geograhpic in the United Kingdom at 9pm on Tuesday, June 27th.
