6. Required matching of maturities of assets and liabilities for banking
Are you stating that if a bank is going to loan a 30 year mortgage that is must get 30 year commitments from depositors?
What do you think of the other's you are not responding to?
Explain why you posted #308.
Demand deposits can be invested in very short term t-bills.
Variable rate mortgages probably require 1 year CDs.
Anybody stupid enough to put out 30 yr fixed after what happened to the S&Ls in the 70s should just probably have their charters revoked as being sufficiently clueless.
