Quite ... remember, he'd have had to quit the IMF anyway to fight the French election (can't really do that effectively from another continent!) and the French have a disturbingly high tolerance of appalling conduct by politicians and other public figures. Remember, this is the country which sheltered a notorious paedophile rapist from US courts even after conviction! Even if the French believe he's guilty, as long as he isn't physically detained at the time I doubt it will be any impediment to his campaign - perhaps the reverse.
Which, with conspiracy theories on the agenda, raises the possibility of it being a plot on his own side, perhaps backfiring slightly ... a few more minutes, he'd have been airborne and safely back on French soil, with no risk of extradition and a glamorous legend of how he outwitted NYPD to boost his profile back home!
