Eastland and Northland (with currencies pegged to each other) will share the same yield curve if two conditions are met. First, unrestricted capital mobility must occur between them to ensure that risk-adjusted expected returns will be equalized. Second, the exchange rate between the currencies must be credibly fixed forever. Thus, as long as investors believe that there is no risk in the future of a possible currency appreciation or depreciation, Eastland and Northland will share the same yield curve. A shift in investors’ belief in the credibility of the fixed exchange rate will likely cause risk and yield differentials to emerge. This situation will cause the (default-free) yield curve to differ between Eastland and Northland. 这段话说的是什么意思，总结下来是三元悖论哪个不满足？
