Greg Ip’s risk hairball
Ip puts the chance of a Chinese hard landing at 20%; of the euro falling apart at 40%; and of the US fiscal cliff actually happening at 30%. Individually, each of these risks is bearable. But make the reasonable assumption that they’re independent variables, and it turns out that if you put them all together, the chances of none of them happening are just one in three.
But let’s go a bit further. Let’s say that if none of these things happen, that’s Good. If one of these things happen, that’s Bad. If two of these things happen, that’s Dreadful. And if all three of these things happen, that’s Apocalypse.
Then this is the result that you get. The chances of a good outcome are 33.6%, a bad outcome is 45.2%, a dreadful outcome is 18.8%, and the chances of apocalypse are a small but still scary 2.4%.
You can also look at each possible outcome individually, like this:
The most likely single outcome is the Good one, where everything goes well in all three regions. The next most likely outcome is the bad one where Europe falls apart but the US and China keep things together — that’s 22%. Then comes the bad outcome with a US fiscal cliff while Europe and China muddle through: that’s 14%. And in fourth place is the dreadful outcome where you get the US fiscal cliff and the euro falling apart: that has a substantial 10% probability.
This is what Ip calls the “big hairball of risk”, and it basically explains the flight to quality that we’re seeing globally, with long-term yields below 2% in every major currency in the world. How do you invest in such a world? It’s really hard, but most sensible strategies involve a pretty large degree of downside protection in the form of risk-free assets. “And that sort of disengagement,” says Ip, “can make economic pessimism self-fulfilling.”
Unless, of course, governments take advantage of their ultra-cheap funding to step in with massive economic stimulus.
