How Exporters Build Trust and Expand Trade Through Smarter Financing Choices

For companies trying to sell goods overseas, the biggest challenge is often not competition or tariffs, but uncertainty. Will foreign buyers actually pay? Will customers in another country want the product? And how can exporters survive the financial risks involved in shipping goods across borders?

A new World Bank research paper by economists from the Central Bank of Chile, the World Bank, the University of British Columbia, and Carnegie Mellon University argues that these questions are central to understanding how international trade works. The study, International Trade Finance and Learning Dynamics, shows that exporters gradually build trust and knowledge over time, and this learning shapes both export growth and the way firms finance trade.

Why Exporters Start Cautiously

The researchers analyzed detailed customs data from Chile covering exports between 2005 and 2019. They found that firms entering foreign markets usually begin with “cash-in-advance” payment arrangements, where buyers pay before goods are shipped. This system protects exporters from the risk of non-payment.

As relationships strengthen, exporters increasingly move toward “open account” financing, where goods are delivered first and payment comes later. Open account arrangements are riskier for exporters but easier for importers, making trade smoother and more attractive.

The study found that open account financing accounts for nearly two-thirds of Chile’s export value overall, while cash-in-advance makes up roughly one-third. However, smaller firms, inexperienced exporters, and firms exporting to countries with weaker legal systems rely much more heavily on advance payments.

Exporters selling specialized or differentiated products also tend to use cash-in-advance financing more often because they have stronger bargaining power and can demand safer payment conditions from buyers.

Learning Helps Exports Grow

One of the paper’s key findings is that export relationships improve over time as firms learn more about foreign markets and trading partners. Over the first five years of an export relationship, export volumes rise by more than 26 percent on average, while the use of open account financing steadily increases.

The transition is especially strong in risky destinations where legal systems are weaker and trust takes longer to build. Inexperienced firms also show faster changes in financing patterns because they start with less information about foreign markets.

The researchers found that firms willing to offer open account financing early in a relationship often achieve stronger export growth later on. Exporters starting with high levels of open account financing recorded export growth of around 27 percent over five years, compared with about 22 percent for firms relying more heavily on advance payments.

According to the study, this suggests that firms confident enough to extend credit may already have better knowledge about demand or more reliable trading partners.

Trade Finance Is More Than Just Payment

To explain these patterns, the researchers created a trade model showing how firms learn through repeated interactions. Exporters entering foreign markets do not initially know whether customers will buy their products or whether importers can be trusted. Over time, they gather information through experience.

The model shows that trade finance acts as a tool for managing uncertainty. Cash-in-advance financing allows firms to test new markets without taking large financial risks. Open account financing becomes more common only after exporters gain confidence in buyers and market demand.

The study argues that trade finance should not be seen as a minor contractual detail. Instead, it plays a major role in helping firms enter export markets, survive uncertainty, and expand internationally.

Financial Shocks Can Quickly Damage Trade

The paper also examines what happens when financing costs rise. If borrowing becomes more expensive for foreign buyers, many exporters, depending on advance payments struggle to maintain relationships. As a result, exports fall sharply and some firms stop exporting altogether.

Recovery is much slower because building new relationships takes time. Exporters need repeated interactions to rebuild trust and learn about buyers again.

The researchers found that risky export destinations are especially vulnerable to financial shocks because exporters there rely more heavily on cash-in-advance arrangements. Safer destinations are more affected by higher domestic financing costs because trade there depends more on open account financing.

The study concludes that international trade is built not only on products and prices, but also on trust, learning, and long-term relationships. In a world facing rising financial uncertainty and global supply chain disruptions, these hidden relationships may matter more than ever.
