With a series of tax and trade moves being considered in the United States this year, emerging-market economies are likely to face devaluation pressure and volatility. Three sources of US-fueled economic uncertainty, in particular, will rattle emerging markets in 2017.
The first is a border adjustment tax that would give tax breaks to U.S. exporters, but impose a levy – or, equivalently, disallow deductions – on imports to the U.S. Both President Donald Trump and the Republican-controlled U.S. Congress have said they favour the scheme, which has a fair chance of being enacted. Such a tax, or even the anticipation of its adoption, could drive up the US dollar’s exchange rate (which, ironically, would offset, at least partly, the improvement in the U.S. trade imbalance for which the Trump administration may be hoping).
The second source of uncertainty is the possibility of more aggressive action on Chinese exports to the U.S. The Trump administration has said many times that it will confront China over what it considers unfair trade practices. Trump has openly mused about imposing a 45 per cent tariff on Chinese imports. The introduction of anything close to that would generate downward pressure on the renminbi, given the resulting reduction in demand for Chinese exports.
But such a move would serve to weaken many other currencies as well. My research with Zhi Wang and Kunfu Zhu reveals that about half of Chinese exports to the U.S. are value-added products manufactured with components from South Korea, Japan, Taiwan, Singapore, and other countries. Because products from China are often part of integrated global or regional value chains, a U.S. restriction on its imports from China would indirectly, but very quickly, translate into reduced exports of value-added items by other countries in Asia. This slippage would likely offset any direct increase in these countries’ exports to the U.S., at least in the short and medium term, because re-organising production chains is not a trivial matter.
A third U.S. move that could unsettle emerging markets is faster-than-expected monetary tightening by the Federal Reserve. A large interest-rate hike would translate into U.S. dollar appreciation, and depreciation of developing-economy currencies.
One exception may be the currencies of commodity exporters. Higher commodity prices, triggered in part by anticipation of increased demand as a result of a boost in U.S. infrastructure spending, could cause these countries’ currencies to strengthen. Even on that front, though, some commodity exporters – such as Brazil and Russia – may not see much improvement in their exchange rates, given the drag of other forces on their weak economies.
The challenges that U.S. policy changes pose for emerging-market currencies include not only downward pressure, but also greater volatility. What, then, should emerging-market countries do to enhance their resilience in anticipation of the shockwaves?
One option is to optimise the structure of capital inflows. A second is to boost the flexibility of exchange rates.
On the former, as my research with Hui Tong shows, countries that rely heavily on borrowing from foreign banks or international capital markets are more vulnerable to capital flight than countries that depend mainly on foreign direct investment. Therefore, to guard against exchange-rate volatility or U.S. interest-rate changes, emerging markets should work to improve their business environments to attract FDI, which would reduce their reliance on short-term infusions of “hot money” – and thus lower their vulnerability to abrupt capital-flow reversals.
As for the second option, allowing nominal exchange-rate flexibility would enable currency values to align with underlying economic fundamentals more quickly. Such adjustment is especially important for countries with rigid labor markets. One danger of fixed exchange rates is the risk of an overvalued or undervalued currency, neither of which is good for economic stability. The chance of either scenario is elevated when the forces influencing the equilibrium exchange rate become more volatile.
While the shape and timing of future U.S. policies are uncertain, it seems clear that capital-flow management and nominal exchange-rate flexibility amount to good preparation. To paraphrase Benjamin Franklin, if developing countries fail to prepare, they will have to prepare to fail. - Project Syndicate
