Now for a look at the Chinese currency. China's central bank has set its official yuan midpoint at the highest level in more than two years -- thanks to a solid spot yuan performance a day earlier. Tuesday's official midpoint rose by 0.3 percent to 6.4372 per dollar, the strongest since December, 2015. The spot yuan finished with a strong gain against dollar on Monday. That's after the Bundesbank decided to include the yuan in its reserves and corporate banking clients offloaded dollars.
