Orthodox economics suggests two ways in which things could go wrong. When an economy is running at close to full tilt, so that firms are borrowing and investing as much as banks are willing to lend, a government can only borrow by outbidding private firms for financing. Government “crowds out” private activity in such cases, hurting growth. What is more, as debt accumulates, lenders may ask the government to pay higher interest rates to compensate them for the increased risk of default. These higher rates can tip a government into fiscal crisis, as market jitters raise borrowing costs, further spooking markets. The government must then accept draconian austerity policies, higher inflation (as it prints money to cover its bills) or default.
