No one knows when global investors will stop lending or demand higher interest rates.

没有人知道全球投资者何时会停止放贷或要求上调利率。

Nurses are demanding higher rates of pay.

【rate】护士在要求提高工资。

Now, that's because, you know, investors are always likely to demand a higher rate of interest to compensate them for the greater uncertainty of lending their money for decades as opposed to days or weeks.

那是因为投资者总是会想要追求更高的利率，以补偿他们把钱投放给市场几十年而不是几天或几周所带来的的更大不确定性。
