The IMF has debunked the myth of Osborne's fiscal "credibility"

Slowing the cuts would not trigger a bond market revolt.

There is a huge amount of interesting material in the full IMF staff report on the UK, released today, in particular the lasting damage ("hysteresis" to economists) done by this prolonged period of very low growth.  But in this post I wanted to draw attention to one particular paragraph (it is para 43 on page 38).   I reproduce it here in full:

Some further slowing of consolidation is unlikely to trigger major market turmoil

43. Further slowing consolidation would likely entail the government reneging on its net debt mandate. Would this trigger an adverse market reaction? Such hypotheticals are impossible to answer definitively, but there is little evidence that it would. In particular, fiscal indicators such as deficit and debt levels appear to be weakly related to government bond yields for advanced economies with monetary independence. Though such simple relationships are only suggestive, they indicate that a moderate increase in the UK’s debt-to-GDP ratio may have small effects on UK sovereign risk premia (though a slower pace of fiscal tightening may increase yields through expectations of higher near-term growth and tighter monetary policy).  This conclusion is further supported by the absence of a market response to the easing of the pace of structural adjustment in the 2011 Autumn Statement. Bond yields in the US and UK during the Great  Recession have also correlated positively with equity price movements, indicating that bond yields have been driven more by growth expectations than fears of a sovereign crisis.

This couldn't be clearer.  It is saying two things.  First, the reason long-term gilt yields are low in the UK (and similarly in virtually every other "advanced economy with monetary independence") is weak growth, not "confidence" or "credibility".  "Bond yields are driven more by growth expectations."  That is, yields are low not because of economic confidence but because of its exact opposite. This is precisely what I and others (Simon Wren-Lewis here, and of course Paul Krugman in the US) have long been arguing.  Indeed, the specific evidence the IMF cites - that yields have fallen when stock markets have fallen - is precisely that, in the UK, I first pointed  here a year ago.  

Second, that there is no reason to believe that slowing fiscal consolidation would "trigger an adverse market reaction".  In other words, when the Chancellor said that "these risks [of slowing consolidation] are very real, not imaginary", he was, once again, indulging in evidence-free speculation, not serious analysis.  Indeed, the Fund accurately points out that the main reason yields might rise (slightly, not precipitiously) if fiscal policy were to be loosened would be because of "expectations of higher near-term growth". As I pointed out here, this would be good news.

So, the IMF agrees that the reason gilt yields are low is because of weak growth, not confidence; and that we could loosen policy with minimal risk and probable benefit.  This is an explicit endorsement of the argument set out by Paul Krugman and Richard Layard (and endorsed by a long list of eminent economists, not to mention me) in their Manifesto for Economic Sense:  "there is massive evidence against the confidence argument; all the alleged evidence in favor of the doctrine has evaporated on closer examination."

 As I noted, the Fund's recommendations are, to be polite, inconsistent. But the analysis is spot on. And it explodes whatever is left of the credibility of the analysis underlying the government's fiscal strategy.

Why Clive Lewis was furious when a Trident pledge went missing from his speech

The shadow defence secretary is carving out his own line on security. 

Clive Lewis’s first conference speech as shadow defence secretary has been overshadowed by a row over a last-minute change to his speech, when a section saying that he “would not seek to change” Labour’s policy on renewing Trident submarines disappeared.

Lewis took the stage expecting to make the announcement and was only notified of the change via a post-it note, having reportedly signed it of with the leader’s office in advance. 

Lewis was, I’m told, “fucking furious”, and according to Kevin Schofield over at PoliticsHome, is said to have “punched a wall” in anger at the change. The finger of blame is being pointed at Jeremy Corbyn’s press chief, Seumas Milne.

What’s going on? The important political context is the finely-balanced struggle for power on Labour’s ruling national executive committee, which has tilted away from Corbyn after conference passed a resolution to give the leaders of the Welsh and Scottish parties the right to appoint a representative each to the body. (Corbyn, as leader, has the right to appoint three.)  

One of Corbyn’s more resolvable headaches on the NEC is the GMB, who are increasingly willing to challenge  the Labour leader, and who represent many of the people employed making the submarines themselves. An added source of tension in all this is that the GMB and Unite compete with one another for members in the nuclear industry, and that being seen to be the louder defender of their workers’ interests has proved a good recruiting agent for the GMB in recent years. 

Strike a deal with the GMB over Trident, and it could make passing wider changes to the party rulebook through party conference significantly easier. (Not least because the GMB also accounts for a large chunk of the trade union delegates on the conference floor.) 

So what happened? My understanding is that Milne was not freelancing but acting on clear instruction. Although Team Corbyn are well aware a nuclear deal could ease the path for the wider project, they also know that trying to get Corbyn to strike a pose he doesn’t agree with is a self-defeating task. 

“Jeremy’s biggest strength,” a senior ally of his told me, “is that you absolutely cannot get him to say something he doesn’t believe, and without that, he wouldn’t be leader. But it can make it harder for him to be the leader.”

Corbyn is also of the generation – as are John McDonnell and Diane Abbott – for whom going soft on Trident was symptomatic of Neil Kinnock’s rightward turn. Going easy on this issue was always going be nothing doing. 

There are three big winners in all this. The first, of course, are Corbyn’s internal opponents, who will continue to feel the benefits of the GMB’s support. The second is Iain McNicol, formerly of the GMB. While he enjoys the protection of the GMB, there simply isn’t a majority on the NEC to be found to get rid of him. Corbyn’s inner circle have been increasingly certain they cannot remove McNicol and will insead have to go around him, but this confirms it.

But the third big winner is Lewis. In his praise for NATO – dubbing it a “socialist” organisation, a reference to the fact the Attlee government were its co-creators – and in his rebuffed attempt to park the nuclear issue, he is making himeslf the natural home for those in Labour who agree with Corbyn on the economics but fear that on security issues he is dead on arrival with the electorate.  That position probably accounts for at least 40 per cent of the party membership and around 100 MPs. 

If tomorrow’s Labour party belongs to a figure who has remained in the trenches with Corbyn – which, in my view, is why Emily Thornberry remains worth a bet too – then Clive Lewis has done his chances after 2020 no small amount of good.
