While Thomson Reuters data last week showed that total global investment banking fees fell 7 per cent to $US85 billion ($122b) in 2016, the top five fee-earning banks were all US firms, led by JP Morgan, which netted $5.8b. This is expected to be reflected in bonuses.
Employees in US banks' fixed income divisions are also likely to do better this year, after firms including Goldman Sachs, Bank of America and Citigroup enjoyed revivals in their bond trading divisions, which had been hit by a market downturn.
In Europe there is still public disquiet about levels of pay at financial services firms, making it harder for banks to hand out rewards on the scale enjoyed on Wall Street.
Scrutiny on pay is increasing in Britain following the publication of the Government's green paper into corporate governance last month.
Adding to pressure on the big banks is the rise of boutique firms such as Robey Warshaw and Centerview Partners, which are increasingly winning lucrative advisory roles on blockbuster deals.
Last week it emerged that Mayfair-based boutique Robey Warshaw had almost doubled profits to 36.6m ($64.69). Among the transactions the small firm worked on was FTSE 100 brewer SABMiller's 79b takeover by rival Anheuser-Busch InBev, the largest deal in British corporate history.
