Before assuming that Bank No 2 described in my previous post, read this example.
If John returns from overseas and puts $10,000 in his check account, the balance sheet of the bank shows an increase of $10,000 under cash. If John were the first client of the bank, its balance sheet would look like this.
Liabilities
Deposits 10,000
Total 10,000
Assets Cash 10,000
Total 10,000
It is true that the bank also records a liability to John. However, because the bank has control of the cash, it has a stronger position. John has become a creditor of the bank, so he is now very dependent on the bank honouring its obligations.
If the bank thinks that John is unlikely to withdraw its money, it may make a loan to Pete. Its balance sheet would then look like this.
Liabilities
Deposits 10,000
Total 10,000
Assets
Loans 10,000
Cash 0
Total 10,000
Pete buys a truck from Bill, who deposits the cash he received in the bank. The bank’s balance sheet now looks like this.
Liabilities
Deposits 20,000
Total 20,000
Assets
Loans 10,000
Cash 10,000
Total 20,000
The banks cash to asset ratio is fifty percent, so the bank now complies with the Basel Accords. It easily meets the standards set by governments all over the world.
Despite this compliance, we now have a strange situation where the bank only has $10,000 cash, yet both John and Bill think they have $10,000 in the bank. If they both try to withdraw their cash out at the same time, they will not be able to get it. The bank cannot call in the loan from Pete, because he no longer has the cash. He has brought a truck.
Bill and John’s cash is not lost, but they cannot get hold of it when they demand it. The best the bank could do is to give $5,000 to both Bill and John and make them wait for the rest of their money. The bank could force Pete to repay his loan, but if he has to sell the truck quickly, he might only get $5,000 for it. John and Bill would then be in trouble, as one of them would have lost $5,000.
