The dollar has updated two-month low against the yen on a very quiet Christmas trading on Friday, as investors continued to record profits before the end of the year.
Trading volumes are low, as many Asian countries celebrate Christmas. The European and the US markets will be closed today.
Recovering oil futures also puts pressure on dollar. US crude has risen by more than 9 % this week, while Brent added 2 %.
The dollar index, which reflects the dynamics of the dollar to six major currencies, fell 0.1 % to 97.895, being far below the two-week high of 99.294, recorded last week after the US Federal Reserve raised its key rate.
The Index was still 8.5 % higher than at the beginning of the year, in spite of the fact that it could lose 0.7 % per week and more than 2 % in December.
Dollar fell against the yen by 0.27 % to 120.12, its lowest level since November 3.
"People continue to record profits on dollar positions as the end of the year is approaching" - said Kaneo Ogino from Global-info Co.
The rise of the yen may be limited by uncertainty about the future actions of the Bank of Japan's head, Haruhiko Kuroda, who may try to convince regulators to expand the program of incentives in January.
"Someone is waiting for that Kuroda will take new steps. And it makes them nervous," - said Ogino.
The euro fell against the dollar by 0.12 % to $ 1.0956 and dropped 0.2 % to 131.70 against the yen.
Meanwhile, the Chinese yuan has appreciated against the dollar and may rise slightly this week after seven weeks of decline in a row.
During the Christmas day, the currencies pairs have more volatile movements, as the trading volume is considerably lower because of fewer transactions on the market.
