The capital markets have been on ice since the collapse of Silicon Valley Bank two weeks ago, the Wall Street Journal reported. No companies with investment-grade credit ratings sold new bonds over the seven business days from March 9 through March 17, the first week in March without a new high-grade bond sale since 2013, according to PitchBook LCD. The market for new junk-bond sales has largely stalled this month, and no companies have gone public on the New York Stock Exchange in more than two weeks. March is typically busy for new corporate debt financings: Companies look to secure financing before the blackout period between the end of the first quarter and the kickoff of earnings season, when they typically refrain from bond sales. Lately, a lack of investor confidence and wild swings in the Treasurys market have kept companies on the sidelines. Those with the highest ratings have sold $59.9 billion in new bonds this month, compared with March’s five-year average of $179 billion. The riskier corporations that borrow by issuing higher-yielding junk bonds and leveraged loans are finding it even harder to sell new debt. Companies have raised some $5 billion of junk bonds this month versus the five-year average of $24 billion.
