JERUSALEM, Oct 15 (Reuters) - Israel’s Bank Hapoalim said on Friday it was raising $1 billion in a private bond offering to institutional investors in the United States, Europe and other countries. The issue is for deferred notes known as green CoCo bonds for a maximum period of 10.25 years at an annual interest rate of 3.255%, the bank said. Hapoalim said it had completed the “pricing stage” and that demand for the bonds reached $2.6 billion among dozens of investment groups.
