Final answer:
Funds from a non-Santander check deposited on a Saturday are usually processed on the next business day, with availability possibly within two business days after. Exact availability may vary by bank policy and interbank check clearing times.
Step-by-step explanation:
When a customer deposits a non-Santander check into their account on a Saturday, the funds are usually not available immediately. The bank's policy on check clearance and the processing of deposits may vary, and weekends are typically non-business days. It is common for banks to have a hold time on deposits made with non-bank checks.
As per standard banking procedures, deposits made on weekends will be processed on the next business day, which typically would be Monday, unless there is a public holiday. Then, depending on the bank's clearing process, the funds from a $1,000 check could be available within two business days following the deposit. However, the exact time may vary due to differences in policies and the time required for the check's issuing bank to release the funds.
This scenario mirrors the process banks use when handling larger transactions, such as when Singleton Bank lends $9 million to Hank's Auto Supply and Hank deposits the loan in his checking account with First National. Just as Hank's deposit increases First National's deposits and reserves, showing how banks can expand the money supply through lending, a customer's deposit of a check also contributes to their bank's ledger in a similar, albeit smaller scale, manner.
