Forty-seven individuals walk into branches of three different banks across a mid-sized Indian city over the course of 30 days. Each one makes a cash deposit. Each deposit is between ₹45,000 and ₹49,500. No single transaction crosses the ₹50,000 threshold that would require additional documentation. No individual visits the same branch twice in a week. None of them are on any watchlist.

On paper, nothing happened.

In reality, ₹2.1 crore in illicit funds just entered the formal financial system: clean, undetected, and ready for the next stage of laundering.

This is smurfing. And it is one of the most persistently effective money laundering techniques precisely because it is designed to be invisible to conventional detection systems.
