Colombia's central bank will cut its benchmark interest rate next week, a Reuters poll suggested on Friday, although analysts expect the bank to act cautiously for the rest of the year due to the worsening state of the government's finances. Sixteen of 20 analysts surveyed said the bank would reduce the benchmark interest rate by 25 basis points to 9%, following a sharper-than-expected slowdown in inflation in June. One analyst forecast a 50-basis-point cut, while the remaining three expected the bank to hold the rate steady, as it did in June.
