U.S. money market yields up to one month have shown changes consistent with year-end liquidity preferences. I find that three- and six-month negotiable certificate of deposit (CD), Eurodollar deposit (ED), and banker’s acceptance (BA) yields are also affected by year-end liquidity preferences. Two- and three-month financial commercial paper (CP) yield changes are less pronounced. Banks – CD, ED, and BA issuers – have increased year-end liquidity needs, unlike finance companies – predominant CP issuers. The year-end effect disappears after the 2007-2008 crisis as depositories’ cash holdings increase. CD, ED, and CP yields diverge post-crisis, suggesting that investors no longer consider them close substitutes.
