> the rates that regular banks pay (and receive) for interbank loans Something still doesn't make sense. If bank A borrows $100 from bank B at 1% (positive) interest, then A has to pay back $101 to B. If bank A borrows $100 from bank B at -1% (negative) interest, then A has to pay back $99 to B. In the latter case, A would try to borrow as much as possible, and B would try to never lend anything. What am I missing here?
