HSBC Holdings (HSBC) is planning to sell at least $1 billion in Additional Tier 1 (AT1) bonds, Bloomberg reported Tuesday.

This marks the first major-currency issuance in the market since the recent conflict involving Iran unsettled investors, the report said.

The bank is offering two perpetual notes that can be called after 5.5 years and 10 years, with initial yields of 7.25% and 7.5%, the report said, citing a person familiar with the deal.

HSBC did not immediately respond to MT Newswires' request for comment.
