Why are banker's acceptance so popular for international transactions?

Banker's acceptances are popular for international transactions because they provide a secure and reliable payment mechanism, reducing the risk of default. They facilitate trade by ensuring that the exporter receives payment on a specified date, while the importer can defer payment until the goods are received. This instrument is backed by a bank, enhancing trust between trading parties and allowing for easier financing options. Additionally, they can be easily discounted or sold in the secondary market, increasing liquidity for businesses engaged in international trade.
