DUBAI, May 6 (Reuters) - Commercial Bank of Dubai (CBD)

CBD.DU plans to tap international debt markets for its first dollar-denominated bond, taking advantage of attractive pricing on the back of returning investor confidence in the emirate.

Gulf Arab banks have stepped up bond sales this year, tapping into substantial investor appetite for bonds issued by regional financial institutions, with over $5 billion of dollar-denominated bonds issued so far this year.

Total year-to-date issuance of dollar bonds in the Gulf is nearly $12 billion.

CBD, rated A- by Fitch, has mandated Citigroup C.N , HSBC Holdings HSBA.L and National Bank of Abu Dhabi NBAD.AD to conduct investor meetings which begin on May 9, ahead of the bond sale, it said in a statement on Monday.

A possible benchmark-sized bond may follow, subject to market conditions. Benchmark-sized bond issues are typically at least $500 million in size.

The programme will help the bank to capitalise on business opportunities and will enable it to benefit from an improving economic cycle in the UAE, Chief Executive Peter Baltussen said in the statement.

CBD, 20 percent owned by Investment Corp of Dubai, has an outstanding loan of $450 million due in August 2014, according to Thomson Reuters data, but has so far not issued any public debt denominated in U.S. dollars.

Banks in the region have been able to take advantage of low borrowing costs to secure funding for regional expansion, as well as bolster their capital ratios.

Last year, bond sales in the financial sector accounted for 44 percent of total bond issuance in the Gulf Cooperation Council (GCC).
