Best time to exchange dollars

Sunat's tax reference rate
Peru's national tax and customs authority, Sunat, published its own reference exchange rate for the day at S/3.391 for purchases and S/3.402 for sales.
Jorge Carrillo Acosta explained that the Sunat exchange rate serves as a reference for tax matters, allowing a person to know what exchange rate to record in their accounting for a purchase, a sale, or a tax declaration.
Bloomberg opening and central bank tracking
The dollar opened trading at S/3.3972 according to preliminary data from the financial data provider Bloomberg.
The outlet also tracked the day's closing exchange rate figure reported by Peru's central bank, the Banco Central de Reserva del Peru, which sets monetary policy and monitors the sol's movements against the dollar.
