WHAT TO EXPECT
WHAT’S going to happen with Brexit? A second referendum? A disorderly hard exit? A new offer from the EU that isn’t as offensive as the deal that just got rejected? God knows, and even he may be uncertain.
Part of the problem is that there don’t seem to be many rational actors out there. Much has been written about the fantasies of many Brexiteers. I don’t have anything to add to all that. But we should also note the fantasies of the Eurocrats, who have behaved at every step of this process as if Britain were Greece, and could be bullied into capitulation. Minor gestures could have saved remain in 2016 – a bit of flexibility, a bit less determination to impose humiliating terms, might have led to a soft Brexit now. But it was arrogance all the way.
Now we hear that EU officials are horrified by the scale of May’s defeat, and my sense is that European leaders are starting to realise that a disorderly break would do a lot of damage to a fragile eurozone, too. No kidding.
Anyway, let’s talk about where the economics of Brexit seem to stand now.
The long-run economics of Brexit still look the same way they did when I and others began analysing the prospect back in 2016. Exit from Europe’s customs union would substantially raise transaction costs on roughly half of Britain’s trade. This would impose a cost on overall British real income that most estimates put at a low single-digit percentage of GDP — say, two to four percent.
This wouldn’t be deliverance some the economic Brexiteers WHEN YOU’RE EXPECTING BREXIT envisioned, but maybe the more important point here is that the effects of Brexit after a few years don’t look catastrophic. How confident can we be that it wouldn’t be too bad? Quite confident, because other countries have managed decently without customs unions despite close economic ties to a much larger neighbour. Put it this way: A post-brexit UK would be to the EU pretty much as Canada was to the US before the Us-canada Free Trade Agreement, which came a few years before NAFTA. In fact, even the share of cross-border trade in GDP would be similar. And Canada wasn’t a howling wasteland. We might also note that there would be some winners from Brexit, even within the UK. The EU has been good for London’s role as a financial centre, but this role has kept the pound high, hurting the industrial North. Brexit would mean a persistently weaker pound, which would mean a bigger manufacturing sector, which would be a benefit to industrial regions – although diluted by higher consumer prices. A significant number of people in Britain might consider this worthwhile.
However, while the long-run effects of Brexit would probably be moderate, the short run could be much worse — both for Britain and for the EU.
The reason the short run could be so ugly is that after almost 45 years in the customs union, neither Britain nor its trading partners have in place the infrastructure that you need to operate a border, even a friendly one. If you aren’t in a customs union – if goods have to clear some kind of border procedure – you need to have a sufficient number of customs inspectors, an adequate computer network, and so on. Without those you’ll experience massive delays – hence the plans to use highways near Dover as massive parking lots to handle the backlog of waiting trucks.
Because that infrastructure isn’t in place, the initial drop in UK-EU trade could be much larger than the longrun effect, and also disorderly, with no guarantee that the highest-priority goods make it through. This kind of disruption at the border is what underlies the huge losses implied by the Bank of England’s worst-case scenarios.
We’ve known about this prospect for quite a while; I’d be curious to know what steps the UK government has taken to limit the damage. They’re aware of the issue, so they must be making adequate preparations, right? I mean, you can’t imagine the US government being completely unprepared for a predictable disaster. Oh, wait.
What’s new, I think, is that the short-run risks for the rest of Europe now look substantially larger than they were even a few months ago. Obviously, EU-UK trade is much smaller relative to the EU economy than it is to Britain’s. But it so happens that a hard Brexit, if it happens, will coincide with what appears to be the worst slowdown since the euro crisis of 2011-12.
That crisis ended with a dramatic monetary intervention, Mario Draghi’s “whatever it takes”. It’s hard to see anything comparable now. In fact, the ECB (European Central Bank) already has negative rates, so there’s no room to cut. And adding a disorderly Brexit to the mix is the last thing Europe needs.
I might add that while I hope and expect that the British civil service has made contingency plans for a sudden hard Brexit, I’m far less sure that the EU has done the same. The point is that even if planning manages to avert massive traffic jams at Dover, that doesn’t help much if they still happen at Calais.
The thing is, an ugly Brexit should be easily avoidable. If the border infrastructure isn’t there, then just postpone the event until it is – or, if that’s impossible for some political reason, settle for minimal enforcement, a customs union in practice though not in principle, while things get sorted out.
And there’s no reason not to believe that things will in fact be worked out – no reason, that is, except everything that has happened between Britain and the EU so far.
