Credit Suisse Group AG’s dollar-denominated bonds extended losses Thursday, falling further into distress in New York trading after early gains in the bank’s stock fizzled.

The lender’s 1.305% bond due 2027 plunged nearly 10 cents to 62.5 cents on the dollar, trading at spreads above 1,400 basis points — a level associated with distress. The bank’s 4.55% bond due 2026 fell 8.5 cents to 70 cents on the dollar as of 9:11 a.m. in New York, while other maturities were also marked lower, according to Trace data.

Credit Suisse bonds were among the most active in Thursday US credit trading. Its bond due 2027 had the most volume.

Senior unsecured euro-denominated bonds due March 2029 reversed earlier gains, dropping about 2 cents on the euro to trade at 69 cents, according to data compiled by Bloomberg. The declines follow record losses in the debt on Wednesday.

Turmoil in global financial markets had eased earlier Thursday after the Swiss central bank threw a lifeline to Credit Suisse. However, signs of unrest persist as volatility gauges remain elevated amid renewed selling of bank shares.
