The Bloomberg news agency notes in its survey on Sunday that one US dollar costs 9.27 kronor.
The krona has thus strengthened 19.40 percent against the dollar this year, an increase from 17.79 percent when measured a week ago.
The Swiss franc and the euro have also performed strongly – up 14.02 and 13.39 percent respectively this year.
The US dollar has lost ground in general.
The worst performer in the G10 group has been the Japanese yen, which is still up 0.89 percent, while the New Zealand and Canadian dollars have risen 3.81 and 4.44 percent respectively.
