Top bankers at BNP Paribas are frustrated by compliance execs who are getting down to the nitty- gritty, analyzing every expense — even rejecting bankers’ lunches if they don’t recognize the venue.

The French bank feels pressure after pleading guilty to money laundering for regimes in Iran and Cuba, paying nearly $9 billion in fines.

“The bank is taking this very seriously,” said one Wall Street insider. “They’ve put in a lot of controls and there’s more to come.”

BNP had no comment.
