@MadMadMadMadRN @ddayen investment funds. offering credit at interest is a lucrative business. they should perform credit analysis, offer auto loans, etc. people can invest in such funds and earn that interest, at cost of bearing the full investment risk. or they can keep deposits, liquid and attached to the payments system, in postal banks, “earning” something like an overnight policy rate minus 25 bps. 1/

@MadMadMadMadRN @ddayen you can keep all the money you want safe and liquid, but you won’t profit from safe liquid deposits. when you invest for profit, you do so in vehicles detached from the payment systems, whose value fluctuates daily, at your own risk. /fin
