Yellen 'to maintain continuity' at US Fed

Janet Yellen's nomination to run the United States Federal Reserve sends a positive signal to the global and Chinese economies, analysts have said.

President Barack Obama will nominate Fed Vice-Chairwoman Yellen on Wednesday to lead the world's most influential central bank.

If Obama's choice is confirmed by the US Senate, which is expected to endorse her, she will likely guarantee the continuity of the policies established under Ben Bernanke, analysts said.
