At such a time, central banks must step in and set the price of liquidity at a reasonable level – make it a centrally-planned and administered price – rather than let it swing free in response to private-sector supply and demand. This is the doctrine of “lender-of-last-resort.”
此时，央行必须出手干预，将流动性设定在合理的价格水平上——使之成为中央计划和管理的价格——而不是任由它根据私有部门的供求而自由涨落。这就是“最后贷款人”学说。
