// THE SHORT ANSWER

Peak debt is the highest the borrowing reaches over the life of a facility or a season — on a development loan, usually just before the first sales settle; on a seasonal line, when the stock has been bought and not yet sold. Lenders size limits, security and interest reserves against the peak, not the average, because the peak is when the bank is most exposed and the project or season least proven. A forecast that understates the peak is a common reason a facility runs out before the plan does.
