You wire the money. Your bank asks for the fund's bank details. Account number, routing number, SWIFT code, correspondent bank, beneficiary name, reference number. One wrong digit and your money goes somewhere else.
You hit send. The money disappears.
For up to 48 hours, your capital is in limbo. It left your account. It hasn't arrived at the fund. Nobody can tell you exactly where it is. Your bank says "in transit." Transit through what? SWIFT, a messaging network from 1973.
