How Are Emerging Markets Responding To Anticipated US Tightening?

Just back from England and a couple of presentations, one at the CCBS on the Trilemma and monetary policy spillovers. Here are three graphs, related to the presentation, which illustrate how policymakers in different emerging market countries are responding to the stresses their economies are undergoing.

I limit the examination to the BRICs (Brazil, Russia, India, and China) as well as other countries, some of which are included in the “Fragile 5”; the additional countries are South Africa, Indonesia, Mexico, and Turkey. I proxy US monetary policy with the Wu-Xia shadow Fed funds rate, first discussed by Jim in this post.

Recall, in a Mundell-Fleming framework under a quasi-fixed exchange rate, and imperfect capital mobility (notes here), policymakers can respond either by allowing currency depreciation, raising policy rates, or depleting foreign exchange reserves.

It’s interesting to note the wide divergence in depreciations (although one should recall these are rates expressed against the USD, which has appreciated strongly over the last fourteen months). Also, the anticipation of monetary tightening in the US, as measured by the shadow Fed funds rate, is not the only factor stressing emerging markets. The VIX, a key determinant of emerging market exchange rates and current account balances [1] [2] [3], has been slightly elevated as well in the last couple of months.
