To add a bit more here, how does one FTP a demand deposit like a chequing account? The holder of the account has the option to either increase or decrease the account balance and the bank has the option to adjust the interest rate on it (typically zero or close to zero for chequing accounts, maybe even negative when you consider fees). Retail networks typically forward account balances to a centralized Treasury for management and are in turn paid a fair FTP rate by the Treasury for bringing in essentially free money. What is the fair rate for the FTP? The accounting industry takes a predictably narrow view of such things and treats demand deposits as overnight instruments (hence they don't quality for hedge accounting) - if you believe this story you'd pay the retail network the overnight rate on the aggregate balance. But bankers know that when diversified across a large number of clients (particularly multi-product clients), demand deposit balances are relatively stable (or sticky) and one can count on at least a certain portion of the balances to stick around. So the next questions you have to address for the FTP of such accounts is: i) what portion of the demand account balance is stable (or not interest rate sensitive - i.e. the core portion) and ii) what portion of the balances are interest rate sensitive (i.e. likely to flee should rates move upwards). Once this science/art is done you pay a floating rate FTP to the non-core portion and some term FTP rate to the deemed core portion. Then more science/art is required - you have to decide what is the appropriate term FTP rate to pay on the deemed core portion (i.e. you need to estimate the duration).Lots of things to do for only one product, have just scratched the surface. More later when time permits, ALCO calls...
