The Philippine central bank has amended its rules to ease pressure on the peso, which slipped to a four-month low. Officials expanded the coverage of the currency rate risk protection program, allowing clients to hedge their foreign currency obligations or transactions through non-deliverable forwards. The facility now includes non-trade transactions and investments. The peso traded around 55.5 per USD on Tuesday, recovering from a low of 56.40 per USD on April 20th, its lowest since December 1st.
