Will China Lower Interest Rates?

With the Shanghai Composite tumbling 16% this week alone and rattling global markets, readers are asking us, "Will China lower interest rates?" The simple answer is that they already have.

The Shanghai Composite finished in the red today (Wednesday) for the fifth consecutive day. The index was up as much as 4% at one point, but finished the session down 1.3% to 2,927.29.

The benchmark fell below 3,000 for the first time in eight months on Tuesday to close at 2,964.97. In the five days since Aug. 19, the index is down 23.3%.

Even amid Wednesday's new fiscal move, investors continue to ask, "Will China cut interest rates even further?" The PBOC has cut rates five times since November, and some economists expect additional moves by the Chinese government.

Yet many investors and analysts worry that the PBOC's actions won't be enough to stabilize markets, which have been in a tailspin since mid-June…
