This thread with NPV is confusing the liquidity issue with the profit of the bond investment. The issue for this bank was not if this was a good or bad investment in the long run (these bonds might very well turn out to be a good investment the day they are paid back on), the issue here is that the bank's customers wanted to withdraw their money and there was not enough liquidity/cash in the bank so they had to sell something and the best/only thing they could sell was the bonds which right now were worth only $80m and the customer wanted their $100m.
