Wondering whether small loans really lift people out of poverty? The microfinance pros and cons are real: credit expands access and business investment, but a leading randomized trial found no average rise in spending or gains in health, education or empowerment.
This explainer is part of the site’s global development coverage, written for general readers.
| Item | Value |
|---|---|
| Slums in the Hyderabad trial | 104 slums, half randomly given a Spandana branch in 2005 |
| Rise in households with a microcredit loan (first follow-up) | 8.8 percentage points |
| Households in the baseline survey | 2,800 households |
| Households in the endline survey | 6,850 households |
| Timing of the longer-run follow-up | Three to four years after the initial expansion |
These figures come from the NBER working paper and the Harvard Kennedy School Gender Action Portal summary of the same study. Figures can change or be revised, so check the source before you rely on them.
What microfinance promises, and what critics fear
The study behind this guide looked at microcredit, the standard group-based lending product. According to the Harvard summary, supporters believe microfinance can do three big things:
- Eradicate poverty and hunger.
- Improve children’s access to primary education.
- Promote gender equality.
Critics worry about the opposite. They fear microfinance is displacing more effective anti-poverty measures and possibly contributing to over-borrowing, which could lock households into greater long-term poverty.
Both camps make claims about outcomes, so the useful question is what measured results show. That is why a randomized trial matters more than a success story.
The case for microfinance: what the evidence supports
The Hyderabad trial did find real, measurable benefits. They are narrower than the promises above, but they are not nothing.
- More access to credit. About fifteen to 18 months after lending began, households in treated areas were 8.8 percentage points more likely to have a microcredit loan, according to the NBER paper.
- More business investment. Households were no more likely to start any new business, but they were more likely to start several at once, and they invested more in their existing businesses.
- A shift in spending. Spending on durable goods increased, while spending on “temptation goods” such as alcohol, tobacco and gambling declined.
- Gains at the top end. Three to four years on, the average business was still no more profitable, but profits rose at the top end of the distribution.
In short, the credit was used, and some households used it to build or expand businesses and buy lasting goods.
What the Hyderabad trial found
This was, in the authors’ words, the first randomized evaluation of introducing the standard group-based microcredit product in a new market. In 2005, half of 104 slums in Hyderabad, India were randomly selected to get a branch of the lender Spandana. The rest did not, although other lenders were free to enter those slums, according to the NBER paper.
The Harvard summary adds the setup details. Researchers surveyed 2,800 households at baseline and 6,850 at endline. Only women were eligible for the group loans, the program offered no financial literacy or business training, and clients could use the money however they saw fit.

Randomization is what makes the result credible. Because the slums were assigned by chance, differences between them can be traced to the arrival of the lender rather than to who chose to borrow. The paper first appeared as a working paper in May 2013 and was published in 2015.
Where the limits show up
The same trial found that many hoped-for effects did not appear. The authors report no effect on average monthly expenditure per capita, and consumption was still no different in treated areas three to four years later.
The most striking result concerns the wider development goals. The authors found no changes in health, education or women’s empowerment, according to the NBER abstract. The Harvard summary adds that women in program areas were no more likely to make decisions about household spending, investment, savings, health or education.
Two cautions apply. The trial studied one lender in one city, and the summary describes the early results as short term. Even so, the authors say their results are largely consistent with four other evaluations of similar programs in different contexts.
How should you weigh microfinance pros and cons?
Treat microfinance as one tool, not a cure. Credit can help some households invest, yet the average household in this trial did not spend more or see wider gains.
When you read a claim about microloans, a few questions help:
- Does it describe an average effect measured against a comparison group, or a single success story?
- How long after lending began were outcomes measured?
- Did the program add training or other support, or only credit?
- Which outcome is claimed: borrowing, business activity, spending, health, education or empowerment?
For context on what “poverty” measures, the extreme poverty definition explainer sets out the benchmarks. If you want to compare credit with another money flow into poorer households, read about how remittances affect developing economies.
Frequently asked questions
Did microfinance raise household spending in the Hyderabad trial?
Show answer
Not on average. Total spending per person stayed flat, even in the longer follow-up. What changed was the mix: households bought more durable goods and fewer “temptation goods”.
Does microfinance empower women?
Show answer
In this trial it did not. Although the lender channeled the majority of its loans to women, the authors found no change in women’s empowerment, and women were no more likely to make household decisions than in non-program households.
Does microfinance help people start businesses?
Show answer
Only partly. The trial saw more investment in businesses that already existed and a tendency to launch several ventures together, but not a general wave of new firms. Typical profits stayed level, with gains confined to the most profitable businesses.
Does the evidence show microfinance is harmful?
Show answer
The trial does not show that. Critics fear over-borrowing and long-term poverty, but the summaries describe that as a concern, not a finding, so treat it as an open question here. What the trial does show is that average gains in spending and wider development outcomes were not detected.
