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.

Geoffrey Howe dies, aged 88

Howe was Margaret Thatcher's longest serving Cabinet minister – and the man credited with precipitating her downfall.

The former Conservative chancellor Lord Howe, a key figure in the Thatcher government, has died of a suspected heart attack, his family has said. He was 88.

Geoffrey Howe was the longest-serving member of Margaret Thatcher's Cabinet, playing a key role in both her government and her downfall. Born in Port Talbot in 1926, he began his career as a lawyer, and was first elected to parliament in 1964, but lost his seat just 18 months later.

Returning as MP for Reigate in the Conservative election victory of 1970, he served in the government of Edward Heath, first as Solicitor General for England & Wales, then as a Minister of State for Trade. When Margaret Thatcher became opposition leader in 1975, she named Howe as her shadow chancellor.

He retained this brief when the party returned to government in 1979. In the controversial budget of 1981, he outlined a radical monetarist programme, abandoning then-mainstream economic thinking by attempting to rapidly tackle the deficit at a time of recession and unemployment. Following the 1983 election, he was appointed as foreign secretary, in which post he negotiated the return of Hong Kong to China.

In 1989, Thatcher demoted Howe to the position of leader of the house and deputy prime minister. And on 1 November 1990, following disagreements over Britain's relationship with Europe, he resigned from the Cabinet altogether. 

Twelve days later, in a powerful speech explaining his resignation, he attacked the prime minister's attitude to Brussels, and called on his former colleagues to "consider their own response to the tragic conflict of loyalties with which I have myself wrestled for perhaps too long".

Labour Chancellor Denis Healey once described an attack from Howe as "like being savaged by a dead sheep" - but his resignation speech is widely credited for triggering the process that led to Thatcher's downfall. Nine days later, her premiership was over.

Howe retired from the Commons in 1992, and was made a life peer as Baron Howe of Aberavon. He later said that his resignation speech "was not intended as a challenge, it was intended as a way of summarising the importance of Europe". 

Nonetheless, he added: "I am sure that, without [Thatcher's] resignation, we would not have won the 1992 election... If there had been a Labour government from 1992 onwards, New Labour would never have been born."
