Michael Howell, managing director of liquidity specialists CrossBorder Capital, has mapped the massive capital flows escaping Europe and China that have driven U.S. assets to extreme over valuation in recent years. A reversal of this vast tide of liquidity was behind last year's weakness in the U.S. dollar and U.S. bonds. This reversal is still in its infancy. Michael expects that the U.S. dollar has further to fall and 10-year bond yields could hit 4%, with severe implications for markets around the globe.
