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.

Benn vs McDonnell: how Brexit has exposed the fight over Labour's party machine

In the wake of Brexit, should Labour MPs listen more closely to voters, or their own party members?

Two Labour MPs on primetime TV. Two prominent politicians ruling themselves out of a Labour leadership contest. But that was as far as the similarity went.

Hilary Benn was speaking hours after he resigned - or was sacked - from the Shadow Cabinet. He described Jeremy Corbyn as a "good and decent man" but not a leader.

Framing his overnight removal as a matter of conscience, Benn told the BBC's Andrew Marr: "I no longer have confidence in him [Corbyn] and I think the right thing to do would be for him to take that decision."

In Benn's view, diehard leftie pin ups do not go down well in the real world, or on the ballot papers of middle England. 

But while Benn may be drawing on a New Labour truism, this in turn rests on the assumption that voters matter more than the party members when it comes to winning elections.

That assumption was contested moments later by Shadow Chancellor John McDonnell.

Dismissive of the personal appeal of Shadow Cabinet ministers - "we can replace them" - McDonnell's message was that Labour under Corbyn had rejuvenated its electoral machine.

Pointing to success in by-elections and the London mayoral election, McDonnell warned would-be rebels: "Who is sovereign in our party? The people who are soverign are the party members. 

"I'm saying respect the party members. And in that way we can hold together and win the next election."

Indeed, nearly a year on from Corbyn's surprise election to the Labour leadership, it is worth remembering he captured nearly 60% of the 400,000 votes cast. Momentum, the grassroots organisation formed in the wake of his success, now has more than 50 branches around the country.

Come the next election, it will be these grassroots members who will knock on doors, hand out leaflets and perhaps even threaten to deselect MPs.

The question for wavering Labour MPs will be whether what they trust more - their own connection with voters, or this potentially unbiddable party machine.
