When the spread between 10-year US Treasury yields and the federal funds rate narrows and at the same time the prime rate stays unchanged, this mix of indicators most likely forecasts future economic:
选项：
A.growth. B.decline. C.stability.解释：
B is correct. The narrowing spread of this leading indicator foretells a drop in short-term rates and a fall in economic activity. The prime rate is a lagging indicator and typically moves after the economy turns.
该领先指标差距的缩小预示着短期利率的下降和经济活动的下降。优惠利率是一个滞后指标，通常在经济好转后才会变动。
我记得课件里是说长短期利率缩窄，可以认为短期利率变高，长期利率变低，短期利率变高是表明现在经济过热，央行采取紧缩政策；长期利率低，说明不看好未来经济。但是解答里说该指标预示短期利率降低，不太理解这个点，还辛苦帮解答一下。
