This editorial in the WSJ says Argentina's president Macri has taken the right steps for the economy by devaluation of the peso and lifting capital controls. The peso exchange rate fell to 13.3 to the dollar from the central bank peg of 9.8. The central bank raised its short term lending rate to 35-38%, sending signals to capital markets that it was ready to intervene if needed so that the peso would not fall too far, and preserving stability. President Macri is planning to remove the export taxes on wheat, corn and beef, and cutting taxes on soyabeans to increase output.
