Renminbi Devaluation Could Hamper Asian Markets For Years

 | Aug 17, 2015 04:12AM ET

Contrary to so many other elements of the trade relationship between China and the rest of the world, supply chain experts had come to expect a relatively benign relationship between the yuan renminbi and the US dollar. Over the past decade, China’s central bank has either permitted the renminbi to creep slowly upward against the US dollar—at a pace considered glacial by the standards of foreign exchange markets, the FT reports in a recent article —or held it steady in times of stress, such as the global financial crisis of 2008-09.

But this week’s flash devaluation, by as much in one week as the currencies have moved in the last year, has sent shock waves through the markets and upset the long-held and, in hindsight, somewhat complacent view that, at least in terms of that currency pairing, the renminbi was destined to rise with the dollar.

In many ways, the shock is greatest for China’s Asian competitors who had planned on a continued appreciation and are now faced with the possibility of a more competitive China on their doorstep.

You would expect China’s exporters to be delighted with the move, but a combination of gradually appreciating currency since the dollar peg was removed in 2005 and rising inflation—particularly wage inflation—has resulted in many Chinese manufacturers finding themselves at a considerable disadvantage to competitors in Bangladesh, Vietnam and other low-wage countries even after this modest devaluation.

Such manufacturers of low-value products, such as textiles, were looking for a renminbi devaluation in excess of 10% against the US dollar, and who is to say that that may not come about? Beijing is clearly rattled by the slide in the economy’s GDP, by some measures the real growth rate is well below the headline 7% and still falling so we should not rule out the possibility of further falls in the exchange rate.

However, Beijing will also have one eye on debt financing. To the extent that exports may be boosted by a lower exchange rate, debt financing costs are increased. Not just China, but many developing countries that have borrowed heavily on the external finance markets have been fearing the impending rise in the Federal Reserve prime rate and the accompanying rise in the US dollar that will—it is widely expected—accompany the Fed’s move.

As the US dollar has risen this year against global currencies, companies and states have found their external finance costs increase. China is far from alone in this respect and is much better prepared with huge US dollar foreign reserves to weather such a rise, but other developing market economies are not so fortunate as this graph from the Financial Times based in BIS data illustrates the extraordinary rise in debt levels
