Contagion: Looking Ahead to Spain and Italy

The past week has been a busy one for people worried that the Greek debt crisis will soon spread to other countries. Ireland and Portugal have long been seen as susceptible to going the same way as Greece, but recently Italy has joined the group of countries seen to be potentially vulnerable.

So like many, I’ve been thinking a lot about contagion this week. But even though it seems to be common knowledge in the business press that if and when Greece defaults the crisis will immediately deepen for other countries, cogent explanations for why that might happen have been scarce. So I think it’s helpful to try to get more specific about why we think the crisis might or might not spread further to Spain or Italy. That will help us better understand whether those fears are real or overblown.

Most of the economic literature about contagion has focused on its applicability to currency crises, such as the EMU crisis of 1992-3 or the “Asian Flu” of 1998. However, the logic is similar when applied to sovereign debt crises. As a reminder, here’s a list of some of the explanations that have been put forward to explain previous episodes where financial crises spread from country X to nearby and similar country Y:

  • a common external shock: whatever factor originally tipped country X into crisis has the same effect on country Y, so it will also push Y into crisis.
  • the “wake up call”: when country X enters a crisis investors suddenly reevaluate their portfolios for risk, and sell off assets related to any country similar to X, thereby precipitating a crisis for country Y.
  • liquidity concerns among common creditors: crisis in country X causes creditors (e.g. banks) to suffer losses that force them to sell off assets in country Y, precipitating a crisis in Y.
  • cross-market hedging among common creditors: crisis in country X means that the portfolio of creditors (e.g. banks) has suddenly become more risky on average, so they respond by reducing their risk exposure elsewhere in their portfolio, in part by selling off the assets of any similar country also seen as risky, such as Y.
  • political contagion: the actions taken to deal with the crisis in country X (e.g. dropping a fixed exchange rate, or in this case, default) make it less costly for country Y to do the same thing, and investors realize this, sell off the assets of country Y, and thus precipitate a crisis for country Y as well.

The thing that these mechanisms have in common is that they all create a process of self-fulfilling expectations, where a loss of investor demand or confidence causes a sell-off of assets, which causes a crisis, which validates the original loss of confidence.

But in the case of Greece, I don’t think that most of these sources of contagion are of real concern, simply because the crisis has been drawn out over such a long period of time now that investors and creditors have all had plenty of time to expect and plan for a Greek default. So I think that the only one of these possible sources of contagion that might apply in this case is the last one, which for convenience I’ve labeled “political contagion”.

If Greece is seen to default (and it seems likely that however the EU chooses to package and label the terms of the new Greek bailout, it will involve some sort of “soft default”), then investors will have been provided a demonstration of how a limited default could work for other euro countries. This poses an enormous problem for European policymakers. Whatever new bailout and debt restructuring they agree to for Greece — especially if it substantially reduces the Greek debt burden going forward — could prompt Ireland and Portugal to ask for the same terms. On the other hand, if the terms of the Greek deal do not sufficiently reduce Greece’s debt burden then the deal will have done nothing to resolve the fundamental issue of insolvency, and policymakers will be right back where they started at some point down the road.

But developments in the financial markets over the past week have reminded everyone that policymakers may need to worry less about Ireland and Portugal, and instead be more far-sighted and consider first and foremost the impact on Spain and Italy. Because when it comes to those two countries, it is clear to everyone that if the debt crisis takes serious hold on them then a financial crisis will become a financial catastrophe.

Paradoxically, one way to help cut off the speculation in the financial markets that Spain and Italy could at some point be candidates for bailouts and/or debt restructuring would be for the EU and ECB to be relatively generous with Greece. If the transfers to Greece from the core euro countries are large – so large that they are difficult for France and Germany to agree to – then investors will have to draw the conclusion that such a deal could never, ever be applicable to Spain and Italy. Spain and Italy are just too big, and the aid packages that worked for Greece would never be feasible for them. While that wouldn’t necessarily stop speculation that Spain and/or Italy might someday be unable to service their debts, it would definitely stop speculation that they would ever be candidates for a Greek-style managed default. And that might be enough to help.

Who is this guy, anyway? And is Kash his real name?

Yes, Kash Mansori is my real name, and I've been writing online about economics since 2003, with a few breaks here and there. After receiving my PhD in economics in the late 1990s, I did a tour of duty as an economics professor at a small liberal arts college in northern New England. The charm of 6-month long winters eventually wore off, however, and I left the academic world in order to move south to warmer climes. I now live in North Carolina and make my living providing economic consulting services, primarily to US and European companies in the manufacturing, high-tech, and finance industries. I have a couple of kids, I enjoy cooking, and I have maps hanging all over the walls of my house.
