The Future is Debt
At 77 percent of gross domestic product (GDP), federal debt held by the public is now at its highest level since shortly after World War II. If current laws generally remained unchanged, the Congressional Budget Office projects, growing budget deficits would boost that debt sharply over the next 30 years; it would reach 150 percent of GDP in 2047. The prospect of such large and growing debt poses substantial risks for the nation and presents policymakers with significant challenges.
In CBO’s projections, deficits rise over the next three decades—from 2.9 percent of GDP in 2017 to 9.8 percent in 2047—because spending growth is projected to outpace growth in revenues (see figure below). In particular, spending as a share of GDP increases for Social Security, the major health care programs (primarily Medicare), and interest on the government’s debt.
