Fear of floating

March 27, 2019


IN 1971, when Nixon shocked the world by abandoning the convertibility of dollars to gold, he dragged all of us, unwillingly, into the modern era of floating exchange rates. Since then, economic theories have changed. But old habits die hard; economists and policymakers today continue to think and operate as if they live in the old world. This article examines the question of fixed versus floating exchange rate regimes from the new perspective of modern monetary theory (MMT).

In a floating exchange rate regime, the central bank allows the supply and demand for dollars and rupees to determine the exchange rate. This can lead to sharp and erratic movements in exchange rates because of speculation, shifting expectations, and manipulation. The ‘fear of floating’ refers to central bank efforts to stabilise exchange rates by buying and selling dollars to counteract the market forces. These efforts ensure that movements in exchange rates are smooth, stable and predictable, making foreign trade much easier for exporters and importers.

The Bretton-Woods institution of the IMF was formed in 1945 to ensure stability of exchange rates in the post-Second World War era, by lending currencies to member nations facing temporary balance of payments deficits. Post-Second World War, instead of adapting to the strange and unfamiliar demands of a floating exchange rate regime, the vast majority of developing countries preferred to peg their soft currency to the dollar (or some basket of hard currencies). This is known as a ‘managed float’ or ‘dirty float’ regime because the central bank intervenes to ensure that the floating exchange rates remain fairly close to some fixed rate determined by policymakers.

This is said to have several advantages. One is that foreign investors have some confidence about the ability to enter and exit capital markets at known exchange rates; boosting foreign trade and investment, considered keys to rapid growth. The second is that domestic traders, exporters and importers can make plans required to do business, and make investments, because they can determine their costs and revenues in advance, with some degree of confidence. The third is a widespread misperception that a ‘strong’ currency represents a strong economy, and is a symbol of national pride. In fact, these half-truths represent an emotional attachment to a ‘golden’ past, which prevents the adjustments, mental and institutional, required to learn to live in a world of floating exchange rates.

There is a widespread misperception that a ‘strong’ currency represents a strong economy.

‘Fear of floating’ is the idea that the foreign exchange (FX) market would be so erratic and unstable that nearly all foreign trade would suffer heavily, perhaps isolating the economy from the benefits of global trade and capital flows. But free flotation has the benefit that the central bank no longer needs any FX reserves to stabilise the currency; FX crises like the ones we experienced recently simply cannot occur. One of the major recommendations of MMT is that governments should avoid acquiring liabilities denominated in foreign currencies — one of which arises when we attempt to manage the exchange rate.

If we look at major financial crises all over the world in the past few decades, we find that most of them involve government defaults on foreign debts. To move forward, we must replace current Bretton-Woods conventions in which all foreign trade is denominated in dollars. Instead, we must learn to think in terms of currency swaps, based on balanced commodity trades. It is this mental shift, learning to think in new ways, that is the hardest part.

The current system gave the US the extraordinary power to print $30 trillion to rescue global financial institutions, without suffering any adverse consequences. Just like the communist bloc invented bilateral frame agreements to carry on trade without dollars, today the whole world needs to create a consensus on a new method for global trade, which would be fair to all countries, and avoid the disastrous trade wars currently taking place.

Currency crises result when central banks ‘manage’ the exchange rate at the wrong level. This results in a constant need to pump dollars into the market to cater to the excess demand for FX created by overvaluation. Eventually, reserves are depleted, and new loans are necessary, leading the country into a debt trap.

Equally important, import-substitution strategies fail, because domestic substitutes cannot compete with imports made artificially cheap by over-valuation. What is worse is that industries based on the ability to get cheap imports come into existence. For example, despite vast agricultural resources, Pakistan imports $2.5 billion worth of food, including oilseeds. Breaking out of this overvaluation trap is slow, painful, and difficult, because we must allow industries based on cheap imports to collapse and initially subsidise the emergence of new industries, which will be profitable only if competing imports are too expensive because the Pakistani rupee is correctly valued. This will take time, and will require confidence of the private sector in the stability of FX policy regime, to make the necessary long-run investments in new types of business.

Freely floating the rupee shifts the exchange rate risk from the government to the private sector, but insulates the economy as a whole from macroeconomic crises, and also mitigates the harmful effects of fiscal deficits to a large extent. The domestic economy has to learn to operate in a new type of economic environment, where imports are more expensive and riskier to obtain. The FX risk inhibits foreign competition which allows infant industries greater room to grow.

These methods were invented and used by East Asian economies to create the miracle of growth which transformed them from agricultural to industrial economies. Also extremely effective was the tactic of systematic undervaluation of currency, which allows the central bank to accumulate foreign exchange reserves, instead of losing them. This creates the surplus required to support domestic industries, to allow them to grow into export tigers. Today, instead of using failed models like the Washington Consensus based on free-market ideologies, we need to learn new strategies from the rising sun in the East.
