The Colombian Central Bank didn’t intervene on the foreign exchange market in August, the monetary authority said in a statement Monday.
In the first eight months of the year, the monetary authority had bought a net $170.9 million.
So far this year, the central bank bought $539.4 million through put options to slow the peso’s appreciation, and in January and February the bank had sold $368.5 million through call options to control the peso weakness.
The peso, which had hit its strongest level in nine years in June last year, weakened after the Lehman Brothers failure prompted international investors to leave Colombia.
Since early March, though, the peso has strengthened 29%.
The peso ended Monday at 2,015 Colombian pesos to the dollar.
