If we plug the current consensus estimate of Q1 GDP growth and then compute the year-on-year four-quarter percentage change, we get a figure of -2.3%. Thus, based on consensus estimates of GDP for Q1 2009, the four-quarter contraction of GDP will be--in the first quarter of this year--already worse than both the baseline scenario figure （-1.9%） and the more adverse scenario figure （-2.1%）.

然而，根据上述环比增长-5%的主流预测值计算，1季度GDP的同比增长率应为-2.3%；这就是说，即使是在1季度，主流预测的GDP同比增长率就已低于压力测试中假设的基准情形（-1.9%）和悲观情形（-2.1%）的数字了。
