Crude oil for June delivery traded at $113.34 a barrel in New York. Crude oil is Canada’s biggest export, while Norway is the seventh-largest exporter of the commodity. The Swedish krona climbed as much as 0.8 percent to 6.0591 versus the dollar, the strongest level since August 2008, after the Riksbank increased its target lending rate last week by a quarter-percentage point to 1.75 percent. The krona later advanced 0.4 percent to 6.0845. The ECB raised its main refinancing rate earlier this month to 1.25 percent from a record low 1 percent to contain inflation and left the door open for more rate increases even as nations such as Greece and Ireland struggle to contain debt turmoil. The krona has rallied 4.9 percent this year in the best performance among the 10 developed-nation currencies tracked by Bloomberg Correlation-Weighted Currency Indexes. The euro has advanced 3.5 percent.
