Colombia’s central bank announced a plan to purchase up to USD 1.5 bln to boost international reserves and prevent a reduction in the IMF’s flexible credit line. The bank will collect as much as USD 200 mln pm through “put” options only when the official exchange rate, TRM, drops below its 20-day moving average. The first auction will take place on January 2, with the options to be exercised from January 3–31.
