We are heading to a world where the US Federal Reserve is preparing people for the idea of negative interest rates in the next recession (see https://www.frbsf.org/economic-research/publications/economic-letter/2019/february/how-much-could-negative-rates-have-helped-recovery/ https://www.frbsf.org/economic-research/publications/economi...) The "vig" for supporters of Libra seems to be that they capture the interest on money used to purchase Libra. In a negative interest rate world that breaks down. Moreover if the Fed wants to have meaningful negative interest rates you need to impose a haircut on non-bank deposits (i.e., cash or crypto) to avoid hoarding. I am curious how this platform incorporates the possibility of a negative interest rate environment.
