Its not earning interest given their rules. What are some short-term ways of earning some interest?Most bond ETFs carry strong interest rate risks
actually they pay interest, around central bank interest rate minus half basis point, which is a pretty much a thin margin from my perspective, considering that you have full liquidity all the times. any alternative you may consider will prevent from acting in the market in real time and will require some administrative burden that will clearly offset any financial advantage in doing so.
