std::transform
( intersection.begin()
, intersection.end()
, std::back_inserter(domCcyEventPtrs)
, boost::bind(&events_type::event, &events, domCcy, _1)
);

depending on what domCcy is and how you want it passed you may need to 
wrap it in boost::ref or boost::cref.

Also a more succinct approach would be to use the range library.
