Small and medium enterprises are the backbone of the global economy. According to the World Bank, they represent about 90 percent of businesses and more than half of all employment worldwide, and in emerging economies formal SMEs contribute up to 40 percent of national income. Once informal firms are counted, those shares rise even higher. Yet the single largest barrier these firms face is not demand, talent, or ambition. It is access to capital, and the gap between the financing small firms could use and the financing they can actually obtain runs into the trillions of dollars every year.
How Large Is the Gap?
The International Finance Corporation estimates the annual financing gap for formal micro, small, and medium enterprises in developing countries at roughly 5.2 trillion dollars, equivalent to about 1.4 times current global lending to the sector. Around 65 million firms, or 40 percent of formal MSMEs, report unmet financing needs. When informal enterprises are included, total unmet demand is larger still, with combined estimates approaching 8 trillion dollars.
The gap is not spread evenly. It is concentrated in the regions where small firms matter most for jobs and growth. East Asia and the Pacific account for the largest share in absolute terms, while in parts of Sub-Saharan Africa, the Middle East, and North Africa the gap is largest relative to the size of the local economy. Within every region, certain firms are consistently underserved: women-owned businesses face a disproportionate share of the shortfall, as do young firms and those in rural areas, regardless of how sound their underlying business may be.
Why the Gap Persists
This gap is not a temporary shock, and it is not caused by lenders being unwilling to lend. It is structural, rooted in four features of how small-business credit works.
Information asymmetry
Lenders cannot easily see inside a small business. Many firms operate without audited statements, separate business accounts, or a documented credit history. Faced with that uncertainty, a lender’s safest response is to decline or to price defensively. The firm is often sound. It simply cannot prove it in the terms lenders require.
The economics of a small loan
Assessing, approving, and servicing a small loan costs a bank almost as much as a large one, but earns a fraction of the return. That simple math pushes lenders toward larger borrowers and leaves smaller firms underserved even when they are creditworthy.
Collateral requirements
Traditional lending leans heavily on fixed assets as security. Service businesses, young firms, and women-owned enterprises, which are less likely to hold titled property, are systematically disadvantaged regardless of their cash flow or prospects.
Risk perception and the cycle
Small firms are perceived as higher risk, and that perception hardens whenever the economy weakens. As the data below shows, banks tighten credit on smaller borrowers first in a downturn and restore access to them last.
Even in Advanced Economies, Small Firms Borrow on Harder Terms
The gap is widest in developing economies, but its mechanics are visible everywhere, including in markets with deep and sophisticated banking systems. In the United States, where high-frequency lending data is available through the Federal Reserve, banks consistently tighten credit on smaller borrowers during periods of stress. The chart below tracks the net share of banks tightening standards on business loans for small firms against larger firms.
Two patterns stand out. First, credit conditions swing sharply with the cycle. The net share of banks tightening standards spiked to roughly 70 percent in mid-2020, eased into outright loosening through 2021, then tightened again to around 50 percent during the 2023 credit squeeze before normalizing to single digits by early 2026. Second, small firms rarely receive easier treatment than large ones. When banks pull back, smaller borrowers feel it first and recover access last.
For a business without deep cash reserves, even a few months of tighter credit can be the difference between expansion and closure.
If this is the pattern in one of the most developed financial systems in the world, the constraint is far sharper in markets where small firms have fewer lenders to turn to, weaker legal protections for creditors, and less collateral to offer. The advanced-economy data is, in effect, the mild version of a global problem.
Entrepreneurship Is Outpacing Access to Capital
While capital remains constrained, the appetite to start and grow businesses has surged. U.S. business applications jumped from roughly 290,000 per month before 2020 to a peak above 540,000, and they remain elevated at around 500,000 per month in 2026, a sustained increase of nearly two thirds.
This wave of new firms is visible across many economies, not only the United States, as digital tools lower the cost of starting a business and people seek greater independence and resilience after years of disruption. It is a hopeful signal of economic dynamism. But it also widens the financing gap, because more new firms means more demand for capital, advisory support, and markets. New firms are precisely the businesses lenders find hardest to assess, since they have the shortest track record and the least collateral. Without a matching expansion in access to finance, many of these firms will stall before they reach the scale at which they create durable jobs.
Why the Gap Matters Beyond the Firms
The financing gap is not only a problem for individual business owners. Because SMEs drive the majority of employment in most economies, a shortfall in their access to capital translates directly into fewer jobs, slower recovery after shocks, and weaker, less diversified local economies. Closing even part of the gap has an outsized effect: capital that reaches a small firm tends to stay in the local economy, supporting wages, suppliers, and demand in the surrounding community. This is why development institutions treat SME finance not as a niche banking issue but as core economic infrastructure.
What Actually Closes the Gap
Capital alone is not the answer. Decades of development experience show that financing works best when it arrives alongside the capabilities to use it well and the markets to put it to work. Several levers consistently move the needle.
- Investment readiness. Many viable firms are turned down not because they are unprofitable, but because they cannot present their case in the terms lenders and investors require. Structured business advisory support helps firms build the financial records, plans, and governance that unlock financing.
- Market access. Revenue is the cheapest form of capital. Connecting small firms to larger buyers, export channels, and procurement opportunities through market access programs strengthens cash flow and makes firms more creditworthy in the process.
- Blended and patient capital. Development finance institutions, partial credit guarantees, and partner lending networks can absorb the early risk that commercial lenders will not, crowding in private capital over time and stretching every public dollar further.
- Better information. Digital payment records, cash-flow-based lending, and alternative credit scoring let lenders assess firms that lack traditional collateral or audited accounts, directly attacking the information problem at the root of the gap.
The UN Global Facility is built around this integrated model. Rather than treating financing, capability, and market access as separate problems handed off to separate institutions, our programs address them together, so that a firm becomes ready for capital, connected to it, and able to use it productively. You can read more about how the Facility works, or explore our approach to SME recovery.
The Outlook
The financing gap is large, structural, and, on current trends, growing as entrepreneurship outpaces access to capital. But it is not immovable. The same forces widening it, digital adoption and a surge in new firms, also create the tools to close it, from cash-flow lending to scalable advisory. Where capital, capability, and markets arrive together, small firms do not just survive. They become the engines of recovery and growth that economies depend on.
