The repayment of inventory lines of credit is provided by lenders by fees for each transaction, in addition to charges when credit investors reserve guarantees. When granting storage credits, a bank supports the application and approval of a loan, but receives the funds for the loan from a stock lender. When the bank then sells the mortgage to another creditor on the secondary market, it receives the funds that it then uses to repay the stock lender. The Bank benefits from this process by collecting points and original fees. A stock line of credit is made available to mortgage lenders by financial institutions. Lenders depend on the eventual sale of mortgages to repay the financial institution and make a profit. This is why the financial institution that provides the inventory line of credit carefully monitors how any loan with the mortgage lender progresses until it is sold. Storage credits can simply be seen as a way for a bank or similar institution to make funds available to a borrower without using their capital. A small or medium-sized bank might prefer to use storage credits and earn money with dementia fees and the sale of the loan, rather than earn interest and fees on a 30-year mortgage. The fall in the housing market between 2007 and 2008 significantly affected storage credits. The mortgage market dried up because people could no longer afford to own a home.
As the economy recovered, the acquisition of mortgages increased, as did storage credits. Storage credits are similar to receivables financing for branches, although guarantees are generally much larger when granting storage credits. The resemblance lies in the short-term nature of the loan. A short-term revolving line of credit is granted to mortgage lenders to close mortgages, which are then sold in the secondary mortgage market. Inventory loans are commercial loans based on assets. According to Barry Epstein, a mortgage consultant, bank supervisors generally treat stock loans as lines of credit that give them a 100% risk-weighted classification. Epstein proposes that credit listing storage lines be classified in this way, in part because the time risk is days, while the time-risk risk for mortgages is in years.
