America’s imminent debt crisis: Much ado about nothing scary
Live MintThe ruckus in the US over the federal debt ceiling has redirected attention toward soaring public borrowing. Against the backdrop of monetary tightening by the US Federal Reserve, piling up more debt reinforces concern about the explosive growth of the government’s interest obligations. Currently, the interest rate on 10-year government bonds is 3.6%, while the CBO’s inflation forecast for that horizon is 2.4%, so the real interest rate relevant for calculating the interest burden is still only 1.2%. And as the former International Monetary Fund chief economist Olivier Blanchard reminds us in a new book, what matters is the difference between the real interest rate and the growth rate of the economy. If the real interest rate is lower than the growth rate of inflation-adjusted GDP, then the debt ratio can fall even when the government runs budget deficits.
