Central bank independence: the orthodoxy's under attack

Have we handed the foxes the keys to the hen house?

Japan's central bank and treasury are discussing co-operating more on economic policy — news which has sent the Nikkei soaring, opening around 2 per cent higher than it closed yesterday, and rising further throughout today.

We've already had previews of this news. After all, new Prime Minister Shinzo Abe was elected on a promise (or threat?) to force the Bank of Japan to do more monetary easing, and has already made other unconventional moves like "nationalising" industrial stock to encourage private-sector investment.

Nonetheless, it was unclear that Abe would actually pull it off. Business Insider describes it as "one of the most taboo concepts in modern economics", noting that "the Treasury is supposed to do fiscal policy. The central bank is supposed to do monetary policy. And that's that".

But, as with so many orthodoxies of economics, the idea of central bank independence has come under attack since the global financial crisis.

Central banks are supposed to be independent to remove the risk that politicians will use monetary policy the same way they all-too-frequently use fiscal policy: to engineer temporary booms, gain brief popularity, and win elections. By removing control of policy from people who stand to gain if they favour the short- over the long-term, monetary policy ought to be "better run".

Monetary policy is worse for this sort of thing because it depends far more on ideas of credibility and restraint than fiscal does. Much of the job of a central bank involves saying the right things, rather than doing them. There's a thousand ways to hold interest rates low, but doing so while explicitly saying they will be low for the next two years (as with the Evans Rule) is very different from doing so while saying they may rise at any time.

But it's important to remember that an "independent" central bank may be no such thing. If principal-agent problems apply to banks run by democratically elected politicians, they apply just as effectively to banks run by technocratic ex-financiers. Frequently, this works well. As Tyler Cowen wrote in 2009:

The default selection mechanism favors bankers, i.e. lenders, people whose interests make them more favorable towards lower inflation.

Given the trend in monetary policy for most of the last thirty years was a desire to reduce then suppress inflation, that convergence of interests was beneficial. But there's no particular reason to expect the convergence of interests between the economy as a whole and one subsection of it to be a long-term thing.

If nothing else, we get the downsides of "independent" central banks when their policy turns to whether to backstop banks and bankers. As a lengthy Atlantic piece by Simon Johnson from May 2009 describes, too many of those decisions were actively favouring the interests of the finance industry when those interests were in direct opposition to the rest of the nation.

And as we've faced an increasing number of unprecedented situations, even the old truth has come under attack. As Joseph Stiglitz said in India earlier this year:

In the crisis, countries with less independent central banks-China, India, and Brazil-did far, far better than countries with more independent central banks, Europe and the United States. There is no such thing as truly independent institutions. All public institutions are accountable, and the only question is to whom.

Obviously the independence, or not, of the central banks is unlikely to have been the deciding factor between whether China or Europe came out of the crisis intact. But more and more people are starting to realise that concepts of independence need to be re-examined, as technocratic rulers are demonstrated to be just as beholden to their own interests as democratic ones, and as those interests continue to diverge from those of the nation as a whole.

So if Japan is about to break a taboo, maybe it has picked the right time to do it.

What do Labour's lost voters make of the Labour leadership candidates?

What does Newsnight's focus group make of the Labour leadership candidates?

Tonight on Newsnight, an IpsosMori focus group of former Labour voters talks about the four Labour leadership candidates. What did they make of the four candidates?

On Andy Burnham:

“He’s the old guard, with Yvette Cooper”

“It’s the same message they were trying to portray right up to the election”​

“I thought that he acknowledged the fact that they didn’t say sorry during the time of the election, and how can you expect people to vote for you when you’re not actually acknowledging that you were part of the problem”​

“Strongish leader, and at least he’s acknowledging and saying let’s move on from here as opposed to wishy washy”

“I was surprised how long he’d been in politics if he was talking about Tony Blair years – he doesn’t look old enough”

On Jeremy Corbyn:

"“He’s the older guy with the grey hair who’s got all the policies straight out of the sixties and is a bit of a hippy as well is what he comes across as” 

“I agree with most of what he said, I must admit, but I don’t think as a country we can afford his principles”

“He was just going to be the opposite of Conservatives, but there might be policies on the Conservative side that, y’know, might be good policies”

“I’ve heard in the paper he’s the favourite to win the Labour leadership. Well, if that was him, then I won’t be voting for Labour, put it that way”

“I think he’s a very good politician but he’s unelectable as a Prime Minister”

On Yvette Cooper

“She sounds quite positive doesn’t she – for families and their everyday issues”

“Bedroom tax, working tax credits, mainly mum things as well”

“We had Margaret Thatcher obviously years ago, and then I’ve always thought about it being a man, I wanted a man, thinking they were stronger…  she was very strong and decisive as well”

“She was very clear – more so than the other guy [Burnham]”

“I think she’s trying to play down her economics background to sort of distance herself from her husband… I think she’s dumbing herself down”

On Liz Kendall

“None of it came from the heart”

“She just sounds like someone’s told her to say something, it’s not coming from the heart, she needs passion”

“Rather than saying what she’s going to do, she’s attacking”

“She reminded me of a headteacher when she was standing there, and she was quite boring. She just didn’t seem to have any sort of personality, and you can’t imagine her being a leader of a party”

“With Liz Kendall and Andy Burnham there’s a lot of rhetoric but there doesn’t seem to be a lot of direction behind what they’re saying. There seems to be a lot of words but no action.”

And, finally, a piece of advice for all four candidates, should they win the leadership election:

“Get down on your hands and knees and start praying”
