随着联邦债务相对GDP比例达到141 ％ ， 相当于GDP5.8％的利息成本意味着只有4％的平均名义利率，鉴于国会预算办公室的通胀预测，实际利率大约是2 % — —与债务与GDP比率少于40%时的历史利率相当。
With a federal debt of 141% of GDP, that 5.8%-of-GDP interest cost implies an average nominal interest rate of just 4% and, given the CBO’s inflation forecast, a real interest rate of about 2% – similar to historic rates when the debt ratio was less than 40% of GDP.
