The promise was enormous: tiny loans for poor entrepreneurs that would, in theory, help erase global poverty. But a Wall Street Journal deep dive by Gabriele Steinhauser finds that microfinance—pioneered by Nobel laureate Muhammad Yunus and backed by celebrities, development banks, and Wall Street—has largely fallen short of its core mission. It was supposed to serve communities where traditional banks weren't an option. But wooed by high interest rates, "Wall Street and other banks piled into the market," writes Steinhauser. "They bought stakes in microfinance lenders, extended financing, or sold securitized microfinance debt."
As of 2025, the sector has exploded into a $219.7 billion global portfolio serving more than 140 million borrowers, with average debt nearly doubling since 2009 to an average $1,381 since 2009; interest rates can exceed 100% in parts of Latin America. Academic studies show little to no overall income boost for most borrowers.
One study, which looked at Ethiopia, found food consumption declined among those who took out the loans; other negative impacts—from child labor to suicide—have been documented. "Contrary to Yunus's vision that debts shouldn't be collateralized," writes Steinhauser, "most of Cambodian microfinance loans greater than $3,000 are secured by a borrower's land, which is the main hard asset for most poor families." Supporters argue microfinance still delivers useful short-term liquidity. Read the full piece for more on the numbers, the human fallout, and stories of individual borrowers in various countries.
