Insurance usually available from government funded export credit agencies or banks, which will usually cover the majority of accounts receivable owed by specified foreign customers. Typically, such insurance is available to cover up to 85 percent of the accounts receivable for a relatively low premium (this ceiling has been set by international trade agreements).
Some international agencies such as the World Bank’s Multilateral Investment Guarantee Agency (MIGA) also offer such insurance, especially for political risk, but have a poor reputation for paying claims. Export insurance tends to be used by large corporations in connection with big-ticket transactions, e.g., airliners, power generating plants, etc. However, arguably it is small- and medium-sized enterprises (SMEs) and startup companies who are most vulnerable to a default and most likely to need such insurance (but paradoxically are least likely to obtain it).
