DUBAI - Qatar's Commercial Bank launched $500 million in Additional Tier 1 (AT1) bonds at 4.5% on Wednesday after receiving more than $1.1 billion in orders for the debt sale, a document showed.

It had given initial price guidance of around 4.75% for the bonds, which are non-callable for five years.

Barclays, Credit Suisse, Deutsche Bank, HSBC, JPMorgan and QNB Capital arranged the deal.

AT1 bonds, the riskiest debt instruments banks can issue, are designed to be perpetual, but issuers can call them after a specified period.
