MOSCOW, April 16 (Reuters) - The Russian central bank shifted the rouble's floating trading band for the 28th time since mid-February on Friday, allowing the currency to scale fresh 16-month peaks versus the basket, dealers said.
The central bank moved its floating corridor to 33.60-36.60 roubles against the euro-dollar basket from 33.65-36.65 after purchasing a total of around $700 million at the previous boundary on Thursday and Friday, dealers said.
The latest move became the second this week and the 28th in two months.
By 0629 GMT, driven by high oil prices, the rouble had
climbed as far as 33.6197 versus the basket, according to
Reuters data
Trading activity was relatively calm on the MICEX exchange, with Russian exporters continuing to convert part of their dollar and euro revenues into roubles to meet impending tax payments.
