The cost is also the increase in net federal government debt held by the private sector – the most accurate measure of true government indebtedness. Comparing the US Congressional Budget Office’s medium-term forecasts before (in January 2008) and after the crisis, this debt increase is a staggering 40% of GDP.
另一项成本则是私人部门手中不断增加的联邦政府净债务额——该指标是计算政府债务的最准确手段。对比美国国会预算办公室在危机前（2008年1月）和危机后发布的中期预测，这一债务的增加额相当于GDP的40%，足以令人震惊不已了。
