(Version in Español)
Budgets can be full of surprises. And not always good ones. Often times, debt increases significantly because an unforeseen obligation materializes. These contingent liabilities, as they are known in the economist’s jargon, can have significant economic and fiscal costs. In fact, on many occasions, large and unexpected increases in debt across the world were due to the materialization of contingent liabilities. That is why they are often called hidden deficits.
