last resort

Nobody wanted to lend me the money. As a last resort I asked my brother-inlaw, and luckily he was able to help me.

没有人愿意借钱给。后只得向姐夫开，他能够帮。

The state could charge heftily for acting as lender of last resort—or, less desirable, impose a windfall tax on bank profits or a “Tobin tax” on transactions.

国家可对后贷方的银行罚以重款，或退而求其次，对银行利润征收暴利税，或者对银行交易征收“托宾税”。
