NEW YORK ( TheStreet) -- Wells Fargo ( WFC - Get Report) was among U.S. bank stocks trading lower Friday following China's decision to tighten credit and weak economic data on eurozone growth.

The People's Bank of China surprised markets with another increase in banks' reserve requirements as the country attempts to fight rising inflation. The 50-basis-point increase will take effect Feb. 25.

The reserve requirement increase puts a damper on banks' ability to lend by putting a greater amount of deposits with the central bank.
