“…lawmakers generally want to reduce interest rates to quell the fiscal-driven inflation, while also avoiding the speculative attack on the currency that such negative inflation-adjusted interest rates would encourage. They want to reduce the various ways to borrow money to buy private assets, while mandating institutions to buy government debt at interest rates that are below the prevailing inflation rate, and closing the various exit doors that people turn to in order to avoid holding the devaluing currency.”
