From monkey + business, probably a calque of Bengali বাঁদরামি (bãdrami, “mischief”, literally “monkey-behaviour”), from বাঁদর (bãdor, “monkey”) + -আমি (-ami, suffix forming nouns referring to the properties, qualities, or states of the words to which it is attached), from the perception that monkeys behave mischievously.
monkey business (uncountable) (idiomatic, informal)
