GlossaryFed & inflation
Debt monetization
Financing government deficits by creating money, typically through central bank purchases of government debt. It avoids borrowing from private lenders but risks inflation if pushed too far.
Paying with new money
A government that spends more than it collects normally borrows from investors. Monetization is the alternative: the central bank creates money to cover the gap, usually by buying the government’s bonds. The government gets its funding without competing for private savings, and the debt ends up on the central bank’s balance sheet.
Why it is feared
History offers vivid warnings. Weimar Germany in the early 1920s and Zimbabwe in the 2000s financed spending by creating money on a massive scale and suffered hyperinflation that wiped out savings. The underlying mechanism is simple: when money is created much faster than the economy grows, prices rise.
For that reason most advanced economies keep the government’s purse separate from the printing press. The Federal Reserve may buy Treasury securities only in the open market, not directly at auction, and it sets policy to pursue stable prices and maximum employment rather than to finance the government.
The 1951 Accord
The separation has not always held. During and after the Second World War the Fed kept Treasury yields pegged at low levels, effectively buying whatever was needed to hold them there. As inflation rose the arrangement became untenable, and the Treasury–Fed Accord of 1951 restored the Fed’s freedom to set interest rates independently. It is often described as the founding moment of modern central bank independence in the United States.
The grey zone
Large-scale bond purchases since 2008, known as quantitative easing, revived the debate. Defenders say they were monetary policy aimed at the economy and were partly unwound later. Critics say that when a central bank buys a large share of new government debt, the distinction becomes hard to see. Japan, where the central bank has come to hold roughly half of all government bonds, is the example both sides cite.
The test many economists apply is intent and reversibility. Purchases made for monetary reasons and unwound when inflation rises are policy. Purchases a central bank could not stop without triggering a government funding crisis are monetization in all but name — the situation known as fiscal dominance.
