Are markets right to be so laid-back over Greece?

Back in 2012 the last time we had a Greece-related crisis in Europe the papers were filled with pictures of burning euros and "Acropolis Now" headlines. Markets dived and midnight crisis talk followed midnight crisis talk until the situation was resolved (albeit temporarily).

Today, even as Greece and the rest of the eurozone go head-to-head once again, markets are positively laid-back. The risks associated with a Grexit have certainly fallen. Banks have cut their exposure to Greece and the European Central Bank (ECB) has pushed through quantitative easing (QE), a major safety net.

But on the flipside, the notion that a Grexit can be managed makes it all the more likely. It gives each side plenty of room to indulge in brinkmanship and play to their respective electorates and potentially reach a point of no return.So are markets right to be so calm?

The big issue

Greece needs a short-term deal to stop it from running out of money. Formally, 28 February is deadline day the current €240bn rescue package expires then. Informally, it boils down to when the plug is pulled on Greek banks (which still rely on short-term emergency lending from the ECB to keep running), and the Greek government itself runs out of money to pay its creditors which would happen pretty quickly.

At that point, Greece would have no choice but to start printing its own currency (presumably drachma) and default on at least some of its debt (see below).

Both sides have said they want to discuss an extension. But they disagree on the terms. Greece wants a "bridging loan" that allows it to break with the current programme and the reforms it involves. The rest of Europe wants it to commit to extending the current programme.

This may sound like semantics, but it's a big deal. Europe doesn't want to give an inch if it does, it will boost the popularity of anti-austerity parties in other countries, and lead to more requests for special treatment further down the line. But the ruling Greek Syriza party was elected on a promise it would gain concessions from Europe. So it might seem like wordplay, but politically it matters. And if they can't reach a deal, it could be game over.

What would happen?

In the very short run, as Kevin Ferriter of Capital Economics notes, "it is hard to see how the initial reaction at least would be anything other than positive for safe-haven assets and negative for others". That means you could expect demand for US Treasuries (government debt) to rise (and yields to fall).

It might also be helpful for gold (which is why you should hang on to it as portfolio insurance). However, the euro itself may not weaken much further a Greece-free eurozone may be seen as stronger in the longer run.

While unpleasant, most argue that this wouldn't be "Lehman Brothers" part two. The ECB is ready to buy the bonds of any other eurozone countries who fall prey to a market panic, and banks are less exposed to Greece than before. But as Dario Perkins of Lombard Street Research notes: "Nobody really knows what will happen. The ECB's firewalls are untested."

And the biggest problem with allowing Greece to leave the euro is that it breaks "irrevocability" the idea that once you're in the euro, you can't leave.

This is a problem because a Grexit might unnerve savers in other vulnerable countries. "Would Portuguese or Spanish deposit holders keep their euros at home, or would they send them to other, safer' euro countries?" Even if this doesn't happen in the short term, it could easily become an issue in a future crisis.

That said, we're relatively relaxed about the outcome in the short term and would use any weakness caused by Grexit to top up on other good-value eurozone stockmarkets, such as Italy. But in the longer run, even if Grexit is avoided, it's hard to see a solution that deals with this issue over-indebtedness once and for all. Wealth manager Tim Price gives his view here on the longer-term outlook for wider markets.

What happens after Grexit?

What would happen to Greece itself if it leaves the eurozone? Jonathan Loynes and Jennifer McKeown of Capital Economics have outlined one way the process could happen. Firstly, capital controls would need to be imposed and Greek banks closed temporarily, to stop money flooding out of the country. Then a new currency would need to be introduced.

At first this would be "at parity with the euro and all deposits, wage agreements, prices and contracts would be valued on that basis". But it would have to float freely before long, and "would need to drop by as much as 40% in order to restore Greece's competitiveness against the rest of the eurozone".

Inflation driven by drachma-based quantitative easing would be a major risk, although the "vast amount of spare capacity" in the Greek economy might prevent this. A default on at least some of Greece's debt would be an inherent part of any Grexit while this sounds extreme, much of it is now held by public-sector entities, like the ECB.

That would mean tricky talks, but "if Greece avoids defaulting on privately held debt, that may well facilitate an earlier and easier return to market financing". In all, it would be painful but in the long run, by boosting competitiveness, it may "end up as a favourable economic development for both Greece and the rest of the eurozone".
