Over time, the demand for smooth and cost-effective cross-border payments has grown in tandem with the expansion of international e-commerce, remittances, and tourism. Despite this growth, cross-border payments have not kept pace with the extensive modernization seen in domestic payment services worldwide. The predominant use of the traditional correspondent banking model in cross-border payments has not experienced the same level of innovation as domestic payments over recent decades. The primary reason for this disparity is the considerable challenge in managing change within the cross-border payment and settlement space, which is more complex than in the domain of domestic payments and settlements. This complexity arises from the inevitable presence and intricate interactions of multiple jurisdictions with different policy and regulatory requirements, dissimilar standards, operating procedures, and difficulties in organizing necessary collective action.

When executing cross-border payments, several challenges impact end-users, commercial banks, and central banks. Cross-border payments inherently require intermediaries, and the existing intermediaries benefit from substantial barriers to entry. These barriers often result from high fixed and sunk costs needed to interface with users, comply with regulations, build trust in services, and operate large back-offices. The size of these institutions becomes a critical factor due to scale economies in liquidity and risk management, prevalent network externalities in messaging, and the facilitation of transactions through access to multiple counterparties. Restrictions on operating hours and payment processing cut-off times contribute to end-users experiencing uncertainty about the status of payment transactions, while a lack of transparency leaves them without clarity on the fees charged for execution. On the side of commercial banks, challenges include dealing with fragmented settlement infrastructure, the inability to adopt straight-through processing procedures, high reliance on liquidity, and extensive manual operations, all leading to increased costs for end-to-end payment processing.

Additionally, diverse regulations and standards set by central banks for domestic large-value payment and settlement systems, which are also employed in processing cross-border payments, create barriers for all but the largest banks to join multiple systems. This circumstance amplifies the need for a higher number of intermediaries to complete cross-border payments, contributing to an overall increase in the cost of services for end-users.

Cross-border payments to and from emerging market economies and developing countries face additional substantial challenges. Following the global financial crisis, banks have been strategically reducing their correspondent networks, leading to a decline of about one-fifth in cross-border correspondent bank relationships over the past decade. This decline is primarily driven by banks re-evaluating their business strategies and considering risk factors.

Correspondent banks engaged in global operations must adhere to relevant laws and regulations across all jurisdictions. These include compliance with anti-money laundering and combating the financing of terrorism (AML/CFT) regulations, tax transparency codes, and economic and trade sanctions. Recent years have seen stringent enforcement of these regulations, resulting in notable actions and penalties within the banking industry. Faced with heightened regulatory expectations, some banks have opted to scale down or cease providing correspondent services, consolidating business within larger global transaction banks—a phenomenon known as “de-risking.” This de-risking strategy raises concerns as it may jeopardize achievements in financial inclusion and potentially reverse progress in reducing remittance prices and fees if banks limit access for money transfer operators.

Moreover, the loss of corresponding banking relationships could have precarious consequences on monetary transmission channels. Small banks and payment service providers, unable to bear increased compliance costs imposed by correspondent banks, may be forced out of the market. Paradoxically, de-risking may also frustrate AML/CFT objectives, proving ineffective in combating financial crime and terrorism financing. This is because pushing higher-risk transactions out of the regulated system and into more opaque, informal channels may make them harder to monitor—a phenomenon referred to as “re-risking.”
