I suggested a couple of days ago that the partial nationalizations of national banking systems that we’re seeing 1 was likely to be a temporary phenomenon, albeit one with long lasting implications for market actors’ expectations. I’m beginning to have second thoughts; I now suspect for two reasons that bank nationalization may be a lot harder to reverse than I thought.
First is the move towards more or less complete deposit guarantees that many Western states are offering (most explicitly Ireland, less explicitly the UK, Germany and others). This is a move that is going to be hard to undo any time soon without risking a further grave crisis of confidence. But it is also one that exposes taxpayers to risks that are far greater and difficult to quantify than the previous system (where many or most advanced industrialized states guaranteed deposits up to a set figure). The moral hazard problems are obvious, and states will want to have as many tools of control to make sure that they don’t get taken for a ride. Large stakes in the relevant firms are one such means of control.
Second – historical institutionalists in political science (Paul Pierson, Jacob Hacker, Kathleen Thelen etc) talk a lot about the importance of sequencing and timing in explaining institutional change. Their arguments might lead one to break up the responses to the crisis into two phases, one of which is likely to build on the other. The first phase is the current one – trying desperately to stop the entire system from breaking down through a variety of measures including injections of liquidity, interest rate cuts, and, most prominently, taking stakes in banks and other financial institutions. The second phase hasn’t really started yet, but will involve trying to build longer term institutions at the domestic level, and (to the extent that agreement is possible), the international level too to prevent this kind of thing from happening again.
The key point here is that the second phase isn’t going to begin _ex nihilo_; instead, it’s going to begin in a world that has been reshaped by the emergency measures that are being taken at the moment. And these measures will offer a set of possible tools and means of influence for government that will prominently include use of governments’ ownership stakes in large chunks of the financial system. It will be very tempting indeed for governments that want to secure financial stability to take up these tools and make them part of their permanent apparatus. Nor do the free marketeers seem in a very good position to win the ideological fight against this kind of initiative given their current disarray. Although the _Economist_ and other stalwarts are bravely battling on, as Dani Rodrik notes, Samuel Brittan of all people has declared himself today to be a closet Keynesian and is pushing the case for an expansionary fiscal policy.
1 Or, in Iceland’s case, full nationalization; see also Paul de Grauwe) in the FT this morning for a more general full nationalization proposal.
