Commercial Bank of Qatar (CBQ) may raise as much as $1bn through its planned five-year bond issue, rather than the $500m it originally proposed, according to bankers close to the deal.

The bank plans to price the bond at about 275 basis points above the London interbank offered rate (Libor) mid-swap rate, the mid-point between bids and offers on interest rate contracts.

CBQ also wants to issue a 10-year bond priced at about 400 basis points above the Libor mid-swap rate, according to bankers close to both deals.

The bank started a roadshow to international investors in the US on 4 November.

“A lot of international investors are very interested in getting exposure to Qatar because of the high economic growth predicted over the next few years,” says a UAE-based fixed income banker.

CBQ will complete the bond issue by mid-November, according to the UAE banker.

The bank has appointed the US’ Morgan Stanley and Credit Suisse to advise on the issue.
