Rise in Chinese bond yields sparks concern.

Chinese government-bond yields have remained high after hitting a nine-year peak last Wednesday, when the rate on 10-year debt reached 4.72%. Today, the yield closed flat at 4.71%. The spike has come as the government tightens monetary policy in order to try to rein in soaring lending, and it has led to higher interest rates in the broader economy. That has sparked concerns that China's rebound could be at risk.
