But“ payoff” might be the wrong word, he adds.“ To be clear, this is a financing tool and not intended to generate trading gains,” he clarifies.

Second, at the expiration date, clients can either pony up the cash to pay back the entirety of the loan’ s principal plus interest, or roll over the box spread into a new one and extend the loan, in which case they only owe the interest on the original box. If their portfolio— the collateral— has suffered a loss of 20 % or more in the interim, they
Specialty trading firms often have payback options, too, such as amortization schedules for installment payments. Borrowers can also close part or all of a short box before expiration if their liquidity needs change, though that comes at an extra cost.

Otherwise, the brokerage firm has the right to close out some or all of the client’ s positions.”
