NEW YORK Dec 24 (Reuters) - The U.S. commercial paper market expanded in the latest week for the first week since mid-November, after a recent contraction amid concerns about a muted economic recovery, Federal Reserve data showed on Thursday.

For the week ended Dec. 23, the size of the U.S. commercial paper market, a vital source of short-term funding for companies' daily operations, rose by $9.3 billion to $1.160 trillion outstanding from $1.150 trillion the previous week. (Reporting by Walden Siew and Tom Ryan; Editing by Leslie Adler)
