Is There an Alternative to the US Dollar?

Dmitri Alperovitch talks with geoeconomist Douglas Rediker (Senior Fellow at Brookings and formerly with the IMF Executive Board) about the enduring dominance of the U.S. dollar and why it won't change any time soon.

Why the dollar continues to have no realistic alternatives and why Chinese renminbi is not a viable replacement. Also, what are the prospects and obstacles for seizing Russia's Central Bank Reserves to pay for Ukrainian reconstruction and other budget needs. And is there anything that China can do to diminish the impact of any future U.S. sanctions if it choose to invade Taiwan?
