Argentina must repay $5 billion by the end of 2019. It doesn’t have much to work with. While the country’s foreign reserves total a still somewhat robust $43 billion, that figure shrinks markedly once untouchable assets such as dollar deposits of everyday Argentines and a credit line from China are stripped out. Analysts surveyed by Bloomberg News estimate that the amount that policy makers can actually freely spend is no more than $12.5 billion. One of the analysts, Siobhan Morden of Amherst Pierpont Securities, puts the figure at as little as $6.5 billion.
