THE PESO slid back to the P61-a-dollar level on Tuesday on mixed news about peace talks between the United States and Iran, and as the yen slipped again a day after a joint intervention effort lifted the embattled currency. It climbed to a high of P60.90, while its worst showing was at P61.222 versus the greenback. The peso closed weaker to tracking the yen and following US President Donald J. Trump’s statement of a “last chance” for peace talks with Iran, a trader said in a telephone interview. Against the euro, the yen slipped 0.5% to ¥181.62, down from Monday’s almost nine-month high of ¥179.44. Investors had sold the dollar after the US Federal Reserve kept rates on hold last week, with its losses accelerating following the yen intervention.
