Interbank settlement: Meaning, Criticisms & Real-World Uses

What Is Interbank Settlement?

Interbank settlement refers to the final transfer of funds between two or more financial institutions to discharge payment obligations arising from transactions. It is a critical component of the broader financial systems and operations, ensuring that money effectively moves from one bank to another, completing payment chains for individuals, businesses, and governments. This process typically occurs within a designated payment system, often facilitated by a central bank or a private clearing house. The finality of interbank settlement is crucial for maintaining confidence and stability across financial markets.

History and Origin

The concept of interbank settlement evolved from early methods of physically exchanging cash or gold to reconcile balances between banks. As banking systems grew and transactions became more complex and numerous, the need for more efficient and secure methods became paramount. Early forms involved manual clearing of checks and other instruments.

A significant leap forward in interbank settlement technology occurred with the advent of electronic wire transfer systems. For instance, the U.S. Federal Reserve began transferring funds electronically as early as 1915, and by 1918, it established its own proprietary telecommunications system to process transfers, which evolved into the modern Fedwire system.¹⁴,¹³ This system initially connected the 12 Reserve Banks, the Federal Reserve Board, and the U.S. Treasury via telegraph using Morse code.,¹² Similarly, private sector initiatives like the Clearing House Interbank Payments System (CHIPS) were established, with CHIPS being organized in 1970 by the New York Clearing House.¹¹ These developments laid the groundwork for the highly automated and secure interbank settlement systems in use today, significantly reducing settlement risk and increasing the speed of fund transfers.

Interpreting the Interbank Settlement

Interbank settlement represents the core mechanism by which value is exchanged between different financial entities. Its interpretation centers on the speed, finality, and risk management associated with these transfers. When interbank settlement occurs in "real-time gross settlement" (RTGS) systems, it means that each transaction is settled individually and immediately upon processing, providing immediate finality and significantly reducing credit and liquidity risks for participating institutions. This immediate and final settlement allows banks to manage their positions with precision and provides certainty regarding the funds they hold.

Conversely, systems that rely on multilateral netting for interbank settlement, like CHIPS, aggregate payment obligations throughout the day, settling them at specific intervals. While this method is generally less expensive and more efficient in terms of liquidity usage, it introduces a slight delay and a different risk profile compared to RTGS systems. The interpretation of interbank settlement, therefore, involves understanding the specific rules and operational characteristics of the underlying payment system used for the transfer.

Hypothetical Example

Consider two banks, Bank A and Bank B, engaged in numerous transactions throughout a business day.

Morning: A customer of Bank A sends $50,000 to a customer of Bank B. This creates an obligation for Bank A to pay Bank B.
Mid-day: A different customer of Bank B sends $30,000 to a customer of Bank A. This creates an obligation for Bank B to pay Bank A.
Throughout the day: Many more transactions flow between customers of Bank A and Bank B, resulting in a complex web of debits and credits between the two banks.
End-of-day (or real-time): Instead of settling each individual transaction, the interbank settlement system (e.g., a real-time gross settlement system like Fedwire or a netting system like CHIPS) comes into play.
- RTGS example: If using an RTGS system, as soon as the $50,000 payment from Bank A to Bank B is processed, Bank A's account at the central bank is debited by $50,000 and Bank B's account is credited. The same occurs for the $30,000 payment from Bank B to Bank A, with immediate, individual settlement.
- Netting example: If using a netting system, the system calculates the net position between Bank A and Bank B. If Bank A owes Bank B a total of $100,000 from all transactions and Bank B owes Bank A a total of $70,000, the system would net these obligations, resulting in a single payment of $30,000 from Bank A to Bank B during the settlement run. This final payment marks the interbank settlement for that period.

This example illustrates how interbank settlement simplifies and finalizes the flow of money, moving the actual funds between the banks' accounts, rather than just recording customer transfers.

Practical Applications

Interbank settlement is fundamental to nearly all aspects of modern finance, underpinning vast daily financial flows.

Wholesale Payments: Large-value transactions between corporations, often for trade finance or treasury operations, rely heavily on efficient interbank settlement. For example, a multinational corporation making a $5 million payment to a supplier in another country would see that payment facilitated through interbank settlement networks.¹⁰
Foreign Exchange Transactions: The buying and selling of currencies, a cornerstone of global commerce, require rapid and secure interbank settlement to minimize exchange rate risk and ensure timely delivery of funds. The Clearing House Interbank Payments System (CHIPS) settles around $1.8 trillion daily in domestic and international payments, with 95% of its transactions being the U.S. dollar side of international transfers, highlighting its role in foreign exchange settlement.⁹,⁸,
Securities Settlement: When stocks, bonds, or other financial instruments are traded, the exchange of the security for payment—known as delivery versus payment—requires effective interbank settlement to transfer the funds between the respective parties' banks.
Correspondent Banking: Banks use correspondent accounts with other banks to provide payment services in jurisdictions where they do not have a physical presence. Interbank settlement mechanisms facilitate the movement of funds between these correspondent accounts.
Monetary Policy Implementation: Central banks use interbank settlement systems, such as their RTGS systems, as key channels for implementing monetary policy, managing banks' reserves, and influencing short-term interest rates. The Bank of England, for instance, uses its RTGS infrastructure as the platform through which monetary policy decisions are implemented.

Ef⁷forts to enhance cross-border payments often focus on improving the efficiency, cost, and transparency of interbank settlement mechanisms across different jurisdictions. The⁶ Financial Stability Board (FSB), in coordination with the Bank for International Settlements (BIS) and the International Monetary Fund (IMF), has developed a roadmap to enhance cross-border payments, addressing challenges like high costs, low speed, limited access, and insufficient transparency.

##⁵ Limitations and Criticisms

Despite their critical role, interbank settlement systems face certain limitations and criticisms.

One primary concern, particularly with Real-Time Gross Settlement (RTGS) systems, is their high demand for liquidity. Because each transaction is settled individually and immediately, banks need to hold substantial balances in their accounts at the central bank to ensure they can meet all their payment obligations. This can tie up significant capital that could otherwise be used for lending or investment. While central banks often provide intraday liquidity facilities, managing these positions effectively is a continuous challenge for financial institutions.

An⁴other limitation arises in cross-border payments. Despite advancements, the global interbank settlement landscape remains fragmented. Different countries have varying operating hours for their RTGS systems, leading to delays when transactions span multiple time zones. Furthermore, diverse legal and regulatory frameworks, as well as varying anti-money laundering (AML) and Know Your Customer (KYC) requirements across jurisdictions, add complexity and cost to international interbank settlement. Thi³s lack of harmonization can impede the speed and efficiency of global financial flows and increase compliance burdens for banks involved in correspondent banking relationships. The Bank for International Settlements (BIS) has highlighted that differing legal and regulatory frameworks, economic policy stances, and privacy concerns are key challenges in governing cross-border payment systems.

Fi²nally, while designed for security, these systems are not immune to operational risks, including cyber threats. The interconnected nature of financial markets means that a disruption in a major interbank settlement system could have widespread repercussions, posing a significant systemic risk to the broader financial system. International bodies like the BIS and the International Organization of Securities Commissions (IOSCO) have developed the Principles for Financial Market Infrastructures (PFMI) to address these risks and promote the safety and efficiency of such systems globally.

##¹ Interbank Settlement vs. Payment Clearing

While often used interchangeably by the general public, interbank settlement and payment clearing represent distinct stages within the broader payment process.

Payment clearing is the process of transmitting, reconciling, and, in some cases, confirming payment orders or instructions prior to settlement. It involves the exchange of payment information between banks and the calculation of net obligations. For example, when a check is deposited, the clearing process involves the exchange of information between the depositor's bank and the payer's bank to verify funds and approve the transaction. A clearing house often facilitates this by acting as an intermediary, tallying debits and credits between participating institutions.

Interbank settlement, on the other hand, is the actual, final transfer of funds to discharge the obligations determined during the clearing process. It is the point at which money irrevocably moves from the account of the paying bank to the account of the receiving bank. Clearing precedes settlement. A cleared payment is an acknowledged obligation; a settled payment is a fulfilled obligation. Without settlement, clearing is merely a promise to pay.

FAQs

What is the primary purpose of interbank settlement?

The primary purpose of interbank settlement is to finalize payment obligations between different banks, ensuring that funds are irrevocably transferred from the paying institution to the receiving institution. This provides certainty and reduces financial risk for all parties involved.

How do central banks facilitate interbank settlement?

Central banks typically operate or oversee Real-Time Gross Settlement (RTGS) systems, where banks hold accounts. They facilitate interbank settlement by debiting the account of the sending bank and crediting the account of the receiving bank, often in central bank money, providing immediate and final settlement.

What is the difference between real-time gross settlement (RTGS) and netting systems in interbank settlement?

Real-Time Gross Settlement (RTGS) systems settle each transaction individually and immediately. Netting systems, conversely, aggregate multiple transactions between banks over a period, calculating a single net obligation to be settled at specific intervals. RTGS offers immediate finality but requires more liquidity, while netting is more liquidity-efficient but has a slight delay in finality.

Why is the finality of interbank settlement important?

The finality of interbank settlement is crucial because it eliminates credit risk and liquidity risk for the receiving bank once the funds are transferred. This certainty allows financial institutions to manage their balance sheets effectively and contributes to overall financial stability in the banking system.

What are some challenges in international interbank settlement?

International interbank settlement faces challenges such as differing operating hours of payment systems across time zones, varying legal and regulatory frameworks, and complex compliance requirements (e.g., anti-money laundering). These factors can lead to increased costs, slower processing times, and reduced transparency for cross-border payments.
