Why China should not depreciate the yuan

Currency wars are raging worldwide and China is bearing the brunt of them. The yuan has appreciated sharply over the past several years, exports are sagging and the risk of deflation is growing. Under these circumstances, many suggest that a reversal in Chinese currency policy to weaken the yuan is the most logical course.

That would be a serious mistake.

In fact, as China pursues structural reforms aimed at ensuring its continued development, forced depreciation is about the last thing it needs. It would also be highly problematic for the global economy.

On the surface, the situation certainly appears worrisome — especially when viewed through the currency lens, which captures shifts in Chinese prices relative to those in the rest of the world. The Bank for International Settlements (BIS) says China’s real effective exchange rate — an inflation-adjusted trade-weighted average of the yuan’s value relative to the currencies of a cross-section of China’s trading partners — has increased by 26 per cent over the past four years.

China’s currency has appreciated more than those of any of the other 60 countries that the BIS covers (apart from dysfunctional Venezuela, where the figures are distorted by multiple foreign-exchange regimes). By comparison, the allegedly strong United States dollar is up only 12 per cent in real terms over the same period. Meanwhile, China’s emerging-market counterparts have experienced sharp currency depreciations, with the Brazilian real falling by 16 per cent, the Russian rouble by 32 per cent and the Indian rupee by 12 per cent.

This currency shift is, of course, the functional equivalent of a large hike in the price of Chinese exports. Add to that continued sluggishness in global demand and the once-powerful Chinese export machine is suffering, with total exports down by 3 per cent year-on-year in January. For an economy in which exports account for about 25 per cent of gross domestic product, this is not a trivial development.

STRATEGY IS CHINA’S GREATEST STRENGTH

At the same time, a stronger yuan has made imports less expensive, putting downward pressure on China’s price structure. Unsurprisingly, this has exacerbated the fear of deflation, with the consumer price index (CPI) rising by only 0.8 per cent year-on-year in January and the annual decline in producer prices steepening to 4.3 per cent.

While these trends are undoubtedly being amplified by plummeting world oil prices, China’s core CPI inflation rate (which excludes volatile food and energy prices) was near 1 per cent in January.

Against this background, it is easy to see why many anticipate a tactical adjustment in China’s currency policy, from appreciation to depreciation. Such a move would certainly seem appealing as a way to provide temporary relief from downward pressure on growth and prices. But there are three reasons that such a move could backfire.

First and foremost, a shift in currency policy would undermine — indeed, undo — the progress that China has made on the road to reform and rebalancing. In fact, a stronger yuan is consistent with China’s key objective of shifting from export-intensive growth to consumer-led development. The generally steady appreciation of the yuan — which has risen by 32.6 per cent against the US dollar since mid-2005 — is consistent with this objective and should not be reversed. It strengthens Chinese consumers’ purchasing power and reduces any currency-related subsidy to exports.

During the recent financial crisis, the authorities temporarily suspended China’s yuan-appreciation policy, and the exchange rate was held steady from mid-2008 through early 2010. Given that current circumstances are far less threatening than those in the depths of the Great Crisis, the need for another tactical adjustment in currency policy is far less acute.

Second, a shift to currency depreciation could inflame anti-China sentiment among the country’s major trading partners — especially the US, where Congress has flirted for years with the prospect of imposing trade sanctions on Chinese exporters. A bipartisan coalition in the House of Representatives recently introduced the so-called Currency Reform for Fair Trade Act, which would treat currency undervaluation as a subsidy, allowing US companies to seek higher countervailing duties on imports.

Similarly, American President Barack Obama’s administration has just brought yet another action against China in the World Trade Organization — this time focusing on illegal subsidies that Beijing provided to exporters through so-called “common service platforms” and “demonstration bases”. If China intervenes to push its currency lower, US political support for anti-China trade actions will undoubtedly intensify, pushing the world’s two largest economies closer to the slippery slope of protectionism.

Finally, a yuan-depreciation policy would lead to a sharp escalation in the global currency war. In an era of unprecedented quantitative easing, competitive currency devaluation has become the norm for the world’s major exporters — first the US, then Japan and now Europe. If China joined this race to the bottom, others would be tempted to escalate their actions. World financial markets would be subject to yet another source of serious instability.

Just as Beijing resisted the temptation of yuan depreciation during the Asian financial crisis of 1997-98 — a decision that may have played a pivotal role in arresting regional contagion — it must stay the course today. That is all the more important in a disorderly climate of quantitative easing, where China’s role as a currency anchor may take on even greater importance than it did in the late 1990s.

Strategy is China’s greatest strength. Time and again, Chinese officials have successfully coped with unexpected developments, without losing sight of their long-term strategic objectives. They should work to uphold that record, using the strong yuan as an incentive to redouble efforts at reform and rebalancing, rather than as an excuse to backtrack. This is no time for China to flinch.
