During the G20 summit meeting, concern over the strength of U.S. dollar, along with subsequent exchange traded funds (ETFs), has come up in light of voluminous stimulus packages being put into global economies.

Every country within the G20 have pledged to do whatever is necessary to ease the to assist their economies, reports Steve Chiotakis for Marketplace. They are already injecting around $2 trillion into their economies to fend off recession.

There will also be increased funds of at least $500 billion given to the International Monetary Fund, and new regulations will be put in place to stop banks or other financial entities from creating another similar mess. A type of regulatory college will be established to supervise the world’s largest banks.

A proposal set up by China and backed by Russia could start a new reserve currency system, according to GFT Forex. But for now, most economically developed nations rely on the U.S. dollar as the default world reserve currency and there would need to be mass appeal to kick out the dollar as a world reserve currency.

China has also urged the United States to fix its balance sheets, or else it may lose China as an investor, in an interview with Renita Jablonski for Marketplace. China’s Prime Minister is worried about Chinese investments in the U.S. dollar and the future outlook of the dollar.

It is estimated that around $1 trillion worth of debt has been bought up by China and China can’t help but think that the U.S. dollar’s value may plunge as a result of large money injections.
