Dollar funding of emerging market economies has been in turmoil for months now. Unlike previous turbulence, this episode cannot be attributed to the US Federal Reserve’s moves on interest rates, which have been rising steadily since December 2016 in a calibrated manner.
The upheaval stems from the coincidence of two significant events: the Fed’s long-awaited moves to trim its balance sheet and a substantial increase in issuing US Treasuries to pay for tax cuts. Given the rapid rise in the size of the US deficit, the Fed must respond by slowing plans to shrink its balance sheet. If it does not, Treasuries will absorb such a large share of dollar liquidity that a crisis in the rest of the dollar bond markets is inevitable.
Consider the scale of both events. Starting in October 2017, the Fed began reducing reinvestment of the coupons it receives from debt securities holdings. That shrinkage will peak at $50bn a month by October and total $1tn by December 2019. Meanwhile, the US fiscal deficit is projected to be $804bn in 2018 and $981bn in 2019, implying net issuance by the US government of $1.169tn and $1.171tn, respectively, in the two years.
