In a option there are three risks which can be covered in the FX spt/fwd market.These are spot price risk , local ccy interest rate risk and fioreign ccy risk... if the option is long dated > 1 year or so , one would be able to achieve a complete hedge by doing a forward delta cover but depending on market liquidity one can also do spot and interest rate seperately.... so if one gets a better liquidity via swap markets one can hedge the IR risk there and spot seperately
