Meanwhile, the G20 meeting in Moscow takes place amid speculation of a "currency war" in which countries devalue their currencies to gain a competitive edge.
The Japanese yen has been the currency primarily in focus this week.
Japan, the world’s third-largest economy, faces charges that it is trying to lower the value of the yen to stimulate its economy.
The yen fell to a 21-month low against the U.S. dollar this week and a near three-year trough against the euro.
As the yen falls, Japanese exports become cheaper compared with goods from other regions that are also trying to pull out of an economic malaise.
Earlier this week, the volatility in the currency markets prompted the Group of Seven leading industrial nations, which include the U.S, Canada, four European Union countries, as well as Japan, to warn that volatile movements in exchange rates could adversely hit the global economy and to reaffirm their commitment to market-driven exchange rates.
On Friday, the yen strengthened ahead of the G20 meeting with analysts expecting pressure to be exerted on Japan’s finance minister and central banker to at least commit to not allow the yen to fall much more.
"The greater fear would probably be that this goes further and significantly so," said Bob Gorman, chief portfolio strategist at TD Waterhouse.
"I think that if there is some language that suggests that is not the case and what has happened has happened but you won’t see much more of it, I suspect that would have a calming effect on the markets."
