Bond trading at investment bank Jefferies fell by more than half during the first quarter of its fiscal year, a sign that banks across Wall Street may be in for another quarter of sluggish trading revenues.

Revenue from fixed income fell to $126 million during the three months ending in February, down from $286 million during the year-ago period, according to financial results released Tuesday.

The slowdown was because of “tepid” markets, said Richard Handler, the bank’s CEO. Wall Street wasn’t keen on the announcement.

“The results were horrible,” Erik Oja, analyst at S&P Capital IQ, told The Post.

Leucadia, Jefferies’ parent company, fell 2.7 percent on Tuesday, to $23.14.
