Colombia's central bank launched its fourth dollar purchase auction of the year, approving US$399.8 million out of US$1.196 billion in bids from 46 offers. The three earlier auctions had already bought US$1.096 billion under a reserve accumulation program of up to US$4 billion.
Reserves stand at about US$67.25 billion.
Central bank dollar buying adds demand for dollars against the peso, which tends to weaken the peso and raise the cost of imported feed. The move is a reserve buffer rather than a sign of stress, so the price effect is modest.
