I remember a client back in 2018, an investor named Marcus who was moving a significant sum from his Montreal-based account to a brokerage in New York. He had calculated everything down to the cent, ensuring the bank exchange rate was acceptable. He sent exactly $50,000.00 USD. Two days later, his brokerage statement showed a deposit of $49,975.00.
"Where did the twenty-five dollars go?" he asked me, sounding more annoyed by the lack of transparency than the actual amount. It wasn't a bank fee listed on his Canadian statement—that $30 wire fee had already been charged separately. This was a silent deduction from the principal amount itself.
This is the reality of the correspondent banking network. Marcus's bank didn't have a direct "pipe" to the New York brokerage's bank. Instead, the money had to stop at a third institution—an intermediary. That intermediary bank performed the service of routing the funds and, in exchange, they simply helped themselves to a small slice of the transfer. This is often referred to as a "BEN" (Beneficiary) or "SHA" (Shared) fee structure, and it catches thousands of Canadian investors off guard every year.
