UPDATE 1-StanChart sets guidance on perpetual bond sale-source

(Updates with details, background))

HONG KONG, June 15 (Reuters) - Standard Chartered (STAN.L) (2888.HK) set guidance for its benchmark sale of dollar-denominated perpetual tier 1 bonds at about 9.75 percent, a source familiar with the deal said on Monday.

Standard Chartered's bonds will be callable after 5-½ years and were rated "Baa1" by Moody's, "BBB-plus" by Standard & Poor's and "A" by Fitch.

The rally in credit markets is helping revive sales of subordinated debt, which lie between senior bonds and equities in terms of capital structure, after issuance was badly hit following the collapse of Lehman Brothers in mid-September.

StanCharted has steered a clearer path through the financial crisis than many rivals, reaping the benefits of its focus in Asia and a more resilient loan book.

Bank of America-Merrill Lynch (BAC.N), Credit Suisse (CSGN.VX), Goldman Sachs (GS.N) and Standard Chartered are the lead managers for the sale. (Reporting by Rafael Nam; Editing by Jonathan Hopfner)
