Goldman Sachs is poised to become the first bank since 2000 to advise on more than $1 trillion (€750bn) worth of announced mergers and acquisitions globally in a calendar year, on the back of its role on the surprise deal between custodian giants Bank of New York and Mellon Financial.

The Wall Street bank, which is advising Bank of New York on the $15.7bn deal announced yesterday, also becomes the first house in six years to advise on more than $500bn worth of M&A with a US target on the back of the custodian tie-up, which values the combined equity of the two companies at $43bn.
