Crazy may be hitting the M&A market. Deals in March slowed down but transaction values jumped.

So far this month, there have been 362 U.S. announced transactions, totaling $39.2 billion, according to data from Thomson Reuters. This compares to 653 deals for all of March 2012 that were valued at $37.7 billion, Thomson Reuters says. Compared to last year, there were fewer deals as of March 22 but transaction value has increased. We also still have a week left of March to go.

The month’s biggest deal occurred in real estate. American Realty Capital Properties made a $5.7 billion offer for Cole Credit Property Trust III. TR is valuing the deal at $8.3 billion. A Cole Credit special committee reviewed the American Reality offer and rejected it, Reuters is reporting.

A similar phenomenon is occurring on the private equity side. There have been 59 PE-backed deals so far in March, valued at $8 billion, Thomson Reuters says. This compares to last year when there were 166 transactions, totaling $7.4 billion.

Here’s the top 5 PE deals this month, according to Thomson Reuters (publisher of peHUB).

In fifth place is a real estate deal. Earlier this month, National Financial Realty and Oaktree Capital Management acquired a portfolio of 40 office properties from First States Investors B L.P. for $240.9 million, according to Commercial Property Executive.
