The peso breached the 63-to-a-dollar level yesterday, closing at a fresh record low as  US inflation heated up,  reinforcing expectations of prolonged high interest rates and  boosting the dollar against  emerging-market currencies. Data from the Bankers Association of the Philippines showed the peso closed at 63.06 to $1, weakening by 19 centavos from Wednesday’s 62.87 finish. It surpassed the previous record closing low of 62.90 set on Oct. 8.
