The math is stark. Debt in developing economies has climbed 54 percentage points against GDP since 2010, hitting 168 percent. That is an increase of seven points per year. The last time debt piled up this fast was during the Latin American crisis of the 1970s, and even then the pace was nearly three times slower. World Bank President David Malpass put it plainly on December 23: the size, speed, and breadth of this wave should concern everyone.
What makes this debt wave different from the last four big ones — Latin America in the 1980s, Asia in the late 1990s, the global financial crisis of 2007-2009, and now — is the cast of creditors. Earlier crises involved public debt owed to traditional lenders like the World Bank itself or Western governments. That was a relatively closed system. The current wave is open to all comers. China has become a major creditor for many developing nations. Private bondholders and non-traditional financial institutions have moved in. The mix of public and private borrowing from this wider range of lenders makes the whole thing harder to track and harder to fix.
Malpass wants lawmakers to prioritize debt management and transparency. The logic is simple: if you cannot see who owes what to whom, you cannot stop a crisis before it starts. The World Bank’s study, “Global Waves of Debt,” found the total for emerging and developing economies hit $55 trillion in 2018. That is the fastest and largest accumulation in 50 years. The figure covers both public and private debt, meaning households and companies are leveraged alongside governments. When private debt goes bad, it often becomes public debt anyway — through bailouts, stimulus, or lost tax revenue.
The risk is that debt stops fueling growth and starts fueling collapse. That is the line Malpass is drawing. Debt can pay for roads, schools, and power plants. It can also pay for consumption, corruption, and interest on older debt. The World Bank’s analysis suggests the current wave is heavy on the latter. The pace of accumulation — seven percentage points of GDP per year — leaves little room for productive investment to catch up. Money gets borrowed to service existing loans, not to build new capacity.
Where this leads depends on policymakers. The warning from Malpass is a call to act quickly. But quick action is exactly what the mix of creditors makes difficult. China does not answer to the World Bank. Private bondholders scatter when trouble hits. Transparency is the precondition for any coordinated response, and transparency is what the current system lacks. The Latin American crisis had a clear set of lenders and borrowers. The Asian crisis had the International Monetary Fund. This wave has no such clarity.
The $55 trillion figure is a snapshot of a system under strain. Debt-to-GDP ratios in developing countries have climbed 54 percentage points since 2010. The last comparable buildup ended in the global financial crisis. The one before that ended in the Asian financial crisis. The one before that ended in the Latin American debt crisis. Each time, the crash came faster than anyone expected. Malpass is trying to break that pattern. Whether lawmakers listen will determine if this wave breaks or rolls on.
