That Mark Carney effect in full

The new Governor of the Bank of England makes sweeping changes.

It's our favourite chart, and you can really see the effect new governor Mark Carney is having on the Bank of England.

In all seriousness, though, the Bank's announcement of the meeting of the monetary policy committee (MPC) did contain a bombshell, of sorts:

The implied rise in the expected future path of Bank Rate was not warranted by the recent developments in the domestic economy.

In non-central-bank speak: "don't expect us to raise interest rates any time soon, because the economy is still in the toilet." What they're saying is almost less important than the fact that they're saying it at all, though. Interest rate decisions are normally passed down without any statement at all; we have to wait for the minutes of the MPC to be released a few weeks later to find out what was going through their heads. That pushes the statement from an explanation of their thoughts into active monetary policy in its own right. It is what's known as "forward guidance".

Monetary policy is, at heart, an expectations game. Interest rates, inflation, and even (to a lesser extent) the quantity of money matter because they change the decisions you make about how to plan for the future. If interest rates are low, you're likely to invest. If interest rates are low and likely to stay low, you're likely to invest more. If interest rates are low and the central bank is telling you they'll stay low for quite some time, well then, you may as well buy some stocks or build a bridge or something, because you aren't going to make any profit in a savings account.

Forward guidance is a very Carneyesque thing to be doing (although Mervyn King was no stranger to the concept himself), but there's two sides to the coin: making promises, and keeping them. This guidance isn't particularly controversial, merely stating what we all knew they were thinking; but it's useful to build up trust that when the Bank makes statements, they're statements you can bank on.

How Jim Murphy's mistake cost Labour - and helped make Ruth Davidson

Scottish Labour's former leader's great mistake was to run away from Labour's Scottish referendum, not on it.

The strange revival of Conservative Scotland? Another poll from north of the border, this time from the Times and YouGov, shows the Tories experiencing a revival in Scotland, up to 28 per cent of the vote, enough to net seven extra seats from the SNP.

Adding to the Nationalists’ misery, according to the same poll, they would lose East Dunbartonshire to the Liberal Democrats, reducing their strength in the Commons to a still-formidable 47 seats.

It could be worse than the polls suggest, however. In the elections to the Scottish Parliament last year, parties which backed a No vote in the referendum did better in the first-past-the-post seats than the polls would have suggested – thanks to tactical voting by No voters, who backed whichever party had the best chance of beating the SNP.

The strategic insight of Ruth Davidson, the Conservative leader in Scotland, was to to recast her party as the loudest defender of the Union between Scotland and the rest of the United Kingdom. She has absorbed large chunks of that vote from the Liberal Democrats and Labour, but, paradoxically, at the Holyrood elections at least, the “Unionist coalition” she assembled helped those parties even though it cost the vote share.

The big thing to watch is not just where the parties of the Union make gains, but where they successfully form strong second-places against whoever the strongest pro-Union party is.

Davidson’s popularity and eye for a good photo opportunity – which came first is an interesting question – mean that the natural benefactor in most places will likely be the Tories.

But it could have been very different. The first politician to hit successfully upon the “last defender of the Union” routine was Ian Murray, the last Labour MP in Scotland, who squeezed both the  Liberal Democrat and Conservative vote in his seat of Edinburgh South.

His then-leader in Scotland, Jim Murphy, had a different idea. He fought the election in 2015 to the SNP’s left, with the slogan of “Whether you’re Yes, or No, the Tories have got to go”.  There were a couple of problems with that approach, as one  former staffer put it: “Firstly, the SNP weren’t going to put the Tories in, and everyone knew it. Secondly, no-one but us wanted to move on [from the referendum]”.

Then again under different leadership, this time under Kezia Dugdale, Scottish Labour once again fought a campaign explicitly to the left of the SNP, promising to increase taxation to blunt cuts devolved from Westminster, and an agnostic position on the referendum. Dugdale said she’d be open to voting to leave the United Kingdom if Britain left the European Union. Senior Scottish Labour figures flirted with the idea that the party might be neutral in a forthcoming election. Once again, the party tried to move on – but no-one else wanted to move on.

How different things might be if instead of running away from their referendum campaign, Jim Murphy had run towards it in 2015.
