The End of the Emerging-Market Party

CAMBRIDGE – Enthusiasm for emerging markets has been evaporating this year, and not just because of the US Federal Reserve’s planned cuts in its large-scale asset purchases. Emerging-market stocks and bonds are down for the year and their economic growth is slowing. To see why, it is useful to understand how we got here.

Between 2003 and 2011, GDP in current prices grew by a cumulative 35% in the United States, and by 32%, 36%, and 49% in Great Britain, Japan, and Germany, respectively, all measured in US dollars. In the same period, nominal GDP soared by 348% in Brazil, 346% in China, 331% in Russia, and 203% in India, also in US dollars.

And it was not just these so-called BRIC countries that boomed. Kazakhstan’s output expanded by more than 500%, while Indonesia, Nigeria, Ethiopia, Rwanda, Ukraine, Chile, Colombia, Romania, and Vietnam grew by more than 200% each. This means that average sales, measured in US dollars, by supermarkets, beverage companies, department stores, telecoms, computer shops, and Chinese motorcycle vendors grew at comparable rates in these countries. It makes sense for companies to move to where dollar sales are booming, and for asset managers to put money where GDP growth measured in dollars is fastest.

One might be inclined to interpret this amazing emerging-market performance as a consequence of the growth in the amount of real stuff that these economies produced. But that would be mostly wrong. Consider Brazil. Only 11% of its China-beating nominal GDP growth between 2003 and 2011 was due to growth in real (inflation-adjusted) output. The other 89% resulted from 222% growth in dollar prices in that period, as local-currency prices rose faster than prices in the US and the exchange rate appreciated.

Some of the prices that increased were those of commodities that Brazil exports. This was reflected in a 40% gain in the country’s terms of trade (the price of exports relative to imports), which meant that the same export volumes translated into more dollars.

Russia went through a somewhat similar experience. Real output growth explains only 12.5% of the increase in the US dollar value of nominal GDP in 2003-2011, with the rest attributable to the rise in oil prices, which improved Russia’s terms of trade by 125%, and to a 56% real appreciation of the ruble against the dollar.

By contrast, China’s real growth was three times that of Brazil and Russia, but its terms of trade actually deteriorated by 26%, because its manufactured exports became cheaper while its commodity imports became more expensive. The share of real growth in the main emerging countries’ nominal US dollar GDP growth was 20%.

The three phenomena that boost nominal GDP – increases in real output, a rise in the relative price of exports, and real exchange-rate appreciation – do not operate independently of one another. Countries that grow faster tend to experience real exchange-rate appreciation, a phenomenon known as the Balassa-Samuelson effect. Countries whose terms of trade improve also tend to grow faster and undergo real exchange-rate appreciation as domestic spending of their increased export earnings expands the economy and makes dollars relatively more abundant (and thus cheaper).

Real exchange rates may also appreciate because of increases in capital inflows, which reflect foreign investors’ enthusiasm for the prospects of the country in question. For example, from 2003 to 2011, Turkey’s inflows increased by almost 8% of GDP, which partly explains the 70% increase in prices measured in dollars. Real appreciation could also be caused by inconsistent macroeconomic policies that put the country in a perilous position, as in Argentina and Venezuela.

Distinguishing between these disparate and inter-related phenomena is important, because some are clearly unsustainable. In general, terms-of-trade improvements and capital inflows do not continue permanently: they either stabilize or eventually reverse direction.

Indeed, terms of trade do not have much of a long-term trend and show very pronounced reversion to the mean. While prices of oil, metals, and food rose very significantly after 2003, reaching historic highs sometime between 2008 and 2011, nobody expects similar price increases in the future. The debate is whether prices will remain more or less where they are or decline, as food, metals, and coal prices have already done.

The same can be said of capital inflows and the upward pressure that they place on the real exchange rate. After all, foreign investors are putting their money in the country because they expect to be able to take even more money out in the future; when this occurs, growth tends to slow, if not collapse, as happened in Spain, Portugal, Greece, and Ireland.

In some countries, such as China, Thailand, South Korea, and Vietnam, nominal GDP growth was driven to a large extent by real growth. Moreover, according to the soon-to-be-published Atlas of Economic Complexity, these economies began producing more complex products, a harbinger of sustainable growth. Angola, Ethiopia, Ghana, and Nigeria also had very significant real growth, but nominal GDP was boosted by very large terms-of-trade effects and real appreciation.

For most emerging-market countries, however, nominal GDP growth in the 2003-2011 period was caused by terms-of-trade improvements, capital inflows, and real appreciation. These mean-reverting processes are, well, reverting, implying that the buoyant performance of the recent past is unlikely to return any time soon.

In most countries, the US dollar value of GDP growth handsomely exceeded what would be expected from real growth and a reasonable allowance for the accompanying Balassa-Samuelson effect. The same dynamics that inflated the dollar value of GDP growth in the good years for these countries will now work in the opposite direction: stable or lower export prices will reduce real growth and cause their currencies to stop appreciating or even weaken in real terms. No wonder the party is over.

      An interesting article, not for the faintheart, discussing the relationship between wealth, competitiveness and a countries growth can be found here.

      As much of the worlds future economic growth will happen in emerging markets the articles title should be changed to "The Moderation and Normalisation Of The Emerging-Market Party"

      If you are a rich well connected international banker or financier the party will go on for ever of course. Deprevation and starvation upon the re-allocation of resource is now and ever will be the lot of the poor in whatever country they are found.

      Lo que el comentarista omite decir es 1) que los términos de intercambio "siempre" han favorecido a los países industrializados, 2) que la "revaluación" o apreciación de las monedas fuertes (con respecto a la de los países en vías de desarrollo) se llevó a cabo durante decenios (1970-2000), o 3) que el crecimiento del volumen de las exportaciones ha sido mayor entre los países pobres, en relación al del volumen de las exportaciones de los países ricos.
      La reversión de la tendencia que supone el autor solo se dará cuando el mundo desarrollado encuentre nuevamente su crecimiento y supere los ritmos de los países emergentes.

      Growth is soft:

      The availability heuristic is reigning high and indeed the data could have high causality. But the intrinsic factors that led to high growth cannot be wished away by simple pure-play of investor activity that went long on emerging market currencies and short on the developed world ones for a long time; now with funds drying out the recoil could be in the making.

      The ramifications of the rewind would not stay in the shores of emerging markets alone; the seeds of default are sown, there is no insulation from it, unless major shifts start to happen again.
