How Firms Finance International Trade
Introduction
International trade is rarely a cash-on-delivery affair. When a manufacturer in China ships containers of electronics to a retailer in Germany, the goods can be in transit for weeks, and neither party wants to bear the full risk of the other defaulting. The system that bridges this gap — trade finance — is one of the most important but least visible pillars of the global economy.
When geopolitical crises like the Strait of Hormuz disruptions of July 2026 threaten shipping routes, trade finance becomes both more expensive and harder to obtain, directly impacting the cost of imported goods worldwide.
This article explains how firms finance international trade, the role of banks and financial markets, and what the data tells us about which countries are most exposed to trade finance disruptions.
For context on how businesses fund their operations, see our guides to how firms finance investment and how firms fund working capital.
What trade finance is
Trade finance refers to the financial instruments and products used by companies to facilitate international trade. Its core function is to reduce the risk that either the exporter or importer will fail to fulfill their side of the transaction.
The most common trade finance instruments include:
- Letters of credit (LCs): A bank guarantees that a buyer’s payment to a seller will be received on time and for the correct amount. If the buyer defaults, the bank covers the payment.
- Documentary collections: The exporter’s bank sends shipping documents to the importer’s bank, releasing them only when payment is made.
- Supply chain finance: A financial institution provides early payment to suppliers based on the creditworthiness of the buyer.
- Trade credit insurance: Insures the exporter against the risk of non-payment by the importer.
- Working capital loans: Short-term loans used to finance inventory and receivables related to trade.
According to the World Bank, global trade finance gaps are estimated at over $1.5 trillion, with small and medium-sized enterprises (SMEs) accounting for a disproportionate share of unmet demand.
How firms finance trade: what the data shows
The World Bank Enterprise Surveys capture how firms in different countries finance their operations, including trade-related activities. The data reveals stark differences between economies.
Bank borrowing for working capital
Private sector credit as a share of GDP is a rough proxy for how much bank financing is available to support trade:
| Country | Private Sector Credit (% of GDP) | Context |
|---|---|---|
| Japan | 194.6% | Deep credit markets; ample trade finance |
| China | 194.2% | State-directed lending supports export sector |
| South Korea | 160.3% | Strong trade finance ecosystem |
| United Kingdom | 112.7% | Major trade finance hub (London) |
| Australia | 129.3% | Well-developed banking sector |
| Germany | 77.3% | Moderate — bank-based but capital markets also active |
| Qatar | 119.4% | Oil-driven credit market |
| India | 40.0% | Growing but still constrained trade finance |
| Indonesia | 36.4% | Large trade finance gap |
| Iraq | 14.0% | Severely constrained credit market |
Countries with high credit-to-GDP ratios — like Japan (194.6%), China (194.2%), and South Korea (160.3%) — have deep banking systems that can absorb trade finance shocks. Firms in these countries have alternatives when one channel tightens.
In contrast, Iraq at 14% of GDP and Indonesia at 36.4% have limited access to bank financing, making their trade sectors highly vulnerable when external credit conditions tighten.
Lending interest rates and the cost of trade finance
The cost of trade finance varies enormously by country. Higher lending rates mean more expensive working capital for importers and exporters:
| Country | Lending Interest Rate |
|---|---|
| Kuwait | 5.2% |
| Oman | 5.5% |
| Qatar | 6.2% |
When geopolitical risk spikes — as it has with the Strait of Hormuz crisis — banks in affected regions raise lending rates and tighten credit conditions, making trade finance more expensive for all firms in the region.
How the Strait of Hormuz crisis affects trade finance
The current crisis illustrates three distinct channels through which geopolitical events disrupt trade finance:
1. War risk insurance premiums surge
When a shipping lane becomes a conflict zone, marine insurers either refuse to cover vessels or charge dramatically higher premiums. Bahrain, with 31.3% of its economy in insurance and financial services trade, is a major regional insurance hub and faces direct exposure from claims and premium volatility. War risk premiums for vessels transiting the Strait of Hormuz have historically increased by 10x or more during previous tensions.
2. Letters of credit become harder to obtain
Banks become reluctant to issue letters of credit for goods destined for conflict-adjacent ports. This is particularly problematic for Iraq, where the banking system is already fragile (14.7% NPL ratio, 11.8% capital adequacy) and private sector credit is only 14% of GDP. Even Saudi Arabia — with stronger bank fundamentals — may see LC terms tighten for goods routed through the Strait.
3. Working capital costs rise
As oil prices spike, firms across all sectors face higher input costs, requiring more working capital to maintain the same level of trade. In countries where lending rates are already elevated, this additional financing burden can squeeze margins significantly.
The trade finance gap: who is most vulnerable
The World Bank estimates that the global trade finance gap — the difference between demand for and supply of trade finance — is concentrated in:
- Low-income countries: Banks in these countries have limited access to international correspondent banking networks.
- Small and medium enterprises: SMEs are disproportionately rejected for trade finance due to collateral requirements and information asymmetries.
- Fragile and conflict-affected states: Iraq (14% credit/GDP, 30.2% account ownership) exemplifies this category.
The Strait crisis widens this gap further, as global banks reassess their exposure to the Gulf region and neighboring markets.

The role of digital payments in trade finance
Digital payment infrastructure is increasingly important for trade finance, particularly for smaller transactions and remittance-linked trade.
Saudi Arabia has 75.7% digital payment adoption and 55.4% of adults receive wages digitally, creating a foundation for digital trade finance solutions. Iran also shows high digital payment adoption (86%), though international sanctions limit its integration into the global trade finance system.
In contrast, Iraq has only 25% digital payment adoption and 11.9% mobile money account ownership — meaning most trade finance must flow through a weak traditional banking system that is ill-equipped to handle the current crisis.

What the index cannot tell you
Trade finance statistics provide a useful overview, but they have important limitations:
- Data timeliness: Many of the lending rate and credit statistics are several years old. Trade finance conditions can change within days during a crisis.
- SME coverage: Aggregate credit statistics hide the fact that small firms — which make up the bulk of importers and exporters in developing countries — face disproportionately higher rejection rates for trade finance.
- Informal channels: A significant share of cross-border trade, particularly within regions, uses informal payment channels that don’t appear in formal credit statistics.
