(Bloomberg) -- Holders of China Evergrande Group's dollar bonds have been left on edge after the distressed developer gave no signs of meeting a Thursday deadline for an $83.5 million coupon payment. European banks are trying to reassure investors that their exposure is limited, while staff at the firm's electric vehicle business haven't been paid. Evergrande's stock and bonds traded lower following a 17% rally Thursday. The shares dropped 7.1% to HK$2.48 by the midday break in Hong Kong. China Evergrande New Energy Vehicle Group plunged as much as 23%. Evergrande's 8.25% dollar bond due 2022 was down 2.4 cents on the dollar at 29.6 cents, according to Bloomberg-compiled prices. It jumped the most in 18 months the day before.
