"In the event of nuclear war or an asteroid strike, it is possible the UK government might not pay its debts. Then we'll have other things to worry about. Otherwise, it will, simply because it can - and because the consequences of not doing so are dreadful...Saying that there is any meaningful probability that the UK will default on its debt - which is what downgrading the UK means - is not to take a particular view on the UK economic or fiscal outlook. It is simply not to understand what you are talking about...So how should the government, and the markets, respond to the rating agencies? The former should, and the latter in my view will, simply ignore them."
Paxman: Would you give this country a AAA rating?
Chote: That's not something that we have to reach a judgement on. I think the notion of a credit rating agency in terms of thinking about are the governments finances sustainable -the key difference is that we are in a position where we have our own currency and in that sense we have a greater degree of flexibility that means that the notion of the danger of insolvency is a much different question for us relative to for example countries in the eurozone..
Paxman: You mean we could just print more money
Chote: Well the government has been doing a deal of that. The Bank of England has been doing a deal of that to help keep demand going. So I think that people take a broad view on whether they think this government or any other government is going to deal with the difficulties in the public finances over an appropriate time horizon.
Paxman: A lot of people say it would be a political disaster if we lost the AAA rating. From the point of view of a highly trained economist would it matter?
Chote: Well other countries have seen downgradings and have been in a similar sort of position and it's not made an enormous amount of difference to the reactions the markets have to them. As I say, often credit ratings agencies are looking at the same information that everybody else does and it's not clear what additional information a would-be investor in British government debt learns from that that they couldn't have learned from looking at our forecasts and other forecasts.
In other words, unlike countries in the eurozone, there is no possibility of the UK defaulting, so our fiscal policy is not constrained by markets in the same way; and we should ignore the credit rating agencies, because they're irrelevant. Precisely.
