Capital Controls Are In Again

By SIMON JOHNSON

Simon Johnson is an economics professor at M.I.T.’s Sloan School of Management and a senior fellow at the Peterson Institute for International Economics.

Adair Turner, head of Britain’s Financial Services Authority, has developed a flair for pushing the official conversation on banking forward.

He spoke in favor of a tax on financial services, long before that was fashionable.  This idea has been picked up by  the British and American governments – and in some amended form is likely to emerge from the  Group of 20 intergovernmental summit process  this year.

Mr. Turner also pointed out that much of financial innovation is not actually socially useful – and might, in some instances, be profoundly dangerous.  For a while, it seemed that his voice on this point might be lost in the wilderness.  But then President Obama offered the Volcker rule, which essentially seeks to rein in certain forms of risk-taking (and arguably innovation) by very big banks.

Now Mr. Turner is at it again, this time in the 14th Chintaman Deshmukh Memorial Lecture, delivered at the Reserve Bank of India in Mumbai  this week.

Mr. Turner laid out a more integrated — and skeptical — view of modern finance than we have heard from him before.  He also delved into new issues, of obvious interest to his hosts and — if we are thinking straight — to the rest of us: what do our recent financial crises imply for emerging markets?

He pointed out that the so-called Asian financial crisis of 1997-98 and the more global crisis of 2008-9 had much in common:

… both were rooted in, or at least followed after, sustained increases in the relative importance of financial activity relative to real non-financial economic activity, an increasing “financialisation” of the economy.

The big point here is that the standard thinking about finance is wrong.  More financial development (e.g., an increase in the size of bank deposits or credit relative to gross domestic product) is not necessarily a good thing.

To be sure, “financial repression” in the traditional poorer country fashion – with interest rates held low, often below inflation – was never appealing as it discourages savings, and should not now be a goal.

But allowing finance to become as big as it wants, from usual market processes, is asking for trouble.  The corollary is that “financial liberalization” — just get out of the way, as Alan Greenspan used to argue, and let markets do their thing — can become very dangerous.

This is true for the United States; at one level, the last 30 years have been a series of misguided and excessive financial liberalizations.  But it is also true for other countries, presumably at all income levels.

Much of what Mr. Turner is arguing on these issues is not new — as he acknowledges, the general points have been made eloquently before, in various fashion, by scholars like Jagdish Bhagwati (in broad terms) and Arvind Subramanian (in specific form, with numerous co-authors).

But Mr. Turner has a knack for bringing officials with him.  He is ahead of the intellectual curve, but not so far divorced as to seem out of touch or irrelevant.  And where exactly is he going, on this occasion?

Mr. Turner’s language was nuanced but the thrust of his argument was clear. We should re-evaluate the usual prescription that developing countries (and anyone else) should necessarily open themselves to freer capital flows:

The case that short term capital liberalization is beneficial is … based more on ideology and argument by axiom than on any empirical evidence.

For what we saw in respect to capital flow liberalization in the 1990s (as in respect to domestic financial liberalization in developed countries) was the assertion of a self-confidence ideology which also happened to be in the direct commercial interest of major financial services firms with powerful political influence in the major and developed economies and in particular in the U.S.

Mr. Turner stops short of taking the complete Bhagwati-Subramanian position.  Even the most courageous financial regulator on the planet is apparently not yet ready to endorse restrictions on capital flows between countries — presumably, the lobbying pressure on this point is still too intense.

But this is definitely the direction in which Mr. Turner is moving — and has already moved — the debate.

Restricting capital flows will imply changes in many other aspects of how we organize our economy, including our fiscal deficit (as a great deal of the short-term capital flows around the world are into and out of United States government securities), and what we rely on to sustain growth (as the United States has been a big net importer of foreign capital in recent decades).

And it will have significant implications for our financial system, which, in recent years, has made a great deal of easy money by moving money around the world — and, as Mr.  Turner continues to emphasize, has thus created serious global risks.
