The U.S. dollar index, which measures the greenback's strength against a trade-weighted basket of six major currencies, rose 0.46% to 99.60 on Friday, just below Thursday's more than one-month highs of 99.79. The index ended the week with modest gains of 0.64%.
The dollar rose to two-week highs against the yen, with USD/JPY up 0.91% to 118.77.
The yen weakened after Bank of Japan Governor Haruhiko Kuroda said Friday the central bank has room to provide additional stimulus if necessary.
The dollar rose to one-month highs against the traditional safe haven Swiss franc, with USD/CHF rising 0.83% to 1.0156 in late trade.
The euro remained on the defensive after European Central Bank Mario Draghi signaled Thursday that fresh easing measures could be rolled out as soon as the bank's next meeting in March.
EUR/USD was at 1.0796 late Friday, down 0.72% for the session and ended the week with losses of 1.12%.
Expectations of fresh central bank stimulus bolstered sentiment in global financial markets. Global stocks strengthened after major declines since the start of the year and oil prices rebounded 10%, one of the largest daily rallies ever.
Indications of further possible stimulus also underlined the diverging monetary policy stance between the Federal Reserve and other world central banks.
Higher U.S. interest rates would make the dollar more attractive to yield-seeking investors.
In the week ahead, investors will be looking to Wednesday's Fed policy statement for any indication that the bank is considering slowing the path of interest rate increases this year.
Markets will also be looking to Friday's data on U.S. fourth quarter gross domestic product, which is expected to show that growth slowed to a modest 0.8% from 2.0% in the third quarter.
