Small street food businesses almost always begin with personal savings or family and friends as the primary source of capital. Research by Martha Chen Harvard University and WIEGO highlights that vendors in the informal economy rely heavily on household resources because formal bank loans require collateral and regular income streams many vendors cannot document. This pattern spans continents but varies with local regulation and social networks.
Causes: barriers to formal finance
Several structural barriers push vendors toward informal funding. Lack of legal recognition, unpredictable daily income, and absence of collateral make banks unwilling to extend small business loans. David McKenzie World Bank has documented how microenterprises face high transaction costs and strict lending criteria that exclude many very small traders. In response, vendors use supplier credit—suppliers allow goods on short-term account—or borrow from informal moneylenders, both of which carry higher costs or dependency risks.
Who else steps in and why it matters
Microfinance institutions and NGO programs sometimes offer targeted small loans or grants, and municipal programs in cities with inclusive policies may provide microgrants, training, or low-cost carts. Jonathan Morduch New York University has analyzed microfinance outcomes, noting that while microloans can expand working capital, they do not always translate into long-term growth and can create debt pressure when incomes are volatile. Vendor associations and cooperatives often pool savings or run rotating funds to manage startup needs locally.
Consequences include limited capacity to invest in safer cooking equipment, food-safety training, or insulated storage—factors that affect public health and environmental impacts such as fuel choice and waste handling. Reliance on high-interest informal credit can trap vendors in cycles of repayment, limiting ability to expand beyond a single stall and making businesses vulnerable to shocks like supply disruptions, eviction, or illness.
Cultural and territorial nuances influence financing choices: in some South Asian and Latin American cities, family networks and local savings groups are strong; in parts of Africa vendors may face harsher enforcement and thus avoid formal engagement. Strengthening vendor access to affordable, small-scale finance and legal recognition improves livelihoods, public health, and urban vitality, a conclusion supported by practitioners and researchers working on informal economies.
