Using synthetic data to evaluate the impact of RTGS on systemic risk in the Australian payments system

This paper develops a new methodology for allowing researchers outside central banks to test the extent of payment system risk, and applies this methodology to an investigation of the impact that the introduction of real time gross settlement (RTGS) had on systemic risk in the Australian payments system. System-specific ratios are first developed to extract bilateral payment obligations from aggregate payments data in the Australian RTGS system. This synthetic data is then used to generate a deferred net settlement (DNS) system of similar dimensions to those the Australian system would have had, had RTGS not been introduced. Standard default simulation methodology is then applied to test the levels of systemic risk in both this system and the corresponding RTGS system to ascertain the degree to which the introduction of RTGS is likely to have reduced the level of risk. We find that while the level of systemic risk is likely to have been reduced in the Australian case, the size of the effect is small, a finding consistent with the results of payments system studies in other countries.     

Liquidity-saving mechanisms

This paper studies the incentives of participants in a real-time gross settlement system with and without the addition of a liquidity-saving mechanism (LSM). Participants in the model face a liquidity shock and different costs for delaying payments. They trade off the cost of delaying a payment against the cost of borrowing liquidity from the central bank. The main contribution of the paper is to show that the design of an LSM has important implications for welfare. In particular, parameters determine whether the addition of an LSM increases or decreases welfare.     

A study of competing designs for a liquidity-saving mechanism

We study two designs for a liquidity-saving mechanism (LSM), a queuing arrangement used with an interbank settlement system. With a balance-reactive LSM, banks can set a balance threshold below which payments are not released from the queue, an action not possible with a receipt-reactive LSM. Payments that are costly to delay are settled earlier with a receipt reactive LSM. Payments that are not costly to delay may be queued with a balance reactive LSM but are always delayed with a receipt reactive LSM. We show that either system can provide higher welfare.     

Sequential payments and optimal pricing in payment systems

This paper studies the intraday payment behaviour between heterogeneous banks as well as optimal intraday pricing schemes. The paper shows the social optimality of payment sequencing, which allows a bank to delay payments until the bank receives payments from the counterparty. The payment sequencing allows a bank with high liquidity cost to ‘recycle’ payment inflow from another bank with lower liqudity cost, reducing the aggregate cost of funding of banks to settle all payments. But we also see that the banks have an incentive to delay payments more than the payment sequencing requires. This underscores the importance of social planner’s role reducing settlement delay, while leaving socially efficient payment sequencing. In this context, we compare two different pricing schemes, a standard throughput guideline and a time-varying intraday tariff, to discuss the optimal incentive mechanisms in payment systems for the ‘socially efficient sequential settlement’.     

Currents of Liquidity Flows Created by the Different Type of Payments: the Case of SPEI

In the present study we examine through network model and transactional analysis the structure of participants’ funds assigned to cover their own payments and payments initiated by their clients (third party) in the Mexican Real Time Payment system SPEI 2 2 SPEI is an hybrid system, equivalent to a Real Time Gross Settlement (RTGS)
. First we build two networks by splitting the number of transactions in two sets of operations, namely payments initiated by third parties and by participants. Our main finding in this regards is that both networks have a core-periphery structure and third party payments help to increase connectivity at the core. From the transactional analysis, we found that third party payments use 47% of the total amount of funds - an indication that participants have strong interest to settle third party payment on real time. Further, in the case of third parties’ payments the ratio of external funds vs. funds formed with incoming payments, is 15%-85%, whereas for transactions initiated by participants this ratio is 19%-81%. This finding is an evidence that with third party payments banks are able to increase the overall level of recycling in the system. Copyright © 2015 John Wiley & Sons, Ltd.     

Banks’ intraday liquidity management during operational outages: Theory and evidence from the UK payment system

We investigate how settlement banks in the United Kingdom’s large-value payment system deal with intraday liquidity and operational risk. In particular, we are interested in payments behaviour towards a bank that is, for operational reasons, unable to make but able to receive payments. If other banks did not sufficiently monitor their outgoing payments, these operational shocks could impact the entire payment system because the affected bank could absorb liquidity from the system. Our game-theoretic model predicts that only early in the day, when they are uncertain about the payment instructions they might have to execute, banks stop sending payments to a counterparty which is unable to make payments. Using a non-parametric method, we find that this prediction is supported by the data, implying that banks effectively contain the disruption caused by the operational outage: payment flows between healthy banks remain unaffected.     

Information asymmetries and spillover risk in settlement systems

I show how information asymmetries between agents in different settlement systems can increase the risk that a problem in one may spill over to another. I focus on the strategic behavior of participants who operate in multiple systems as they choose how best to manage their liquidity across the systems. In the event of an operational shock in one system, these participants may continue to make payments in order to avoid delay costs, thereby risking a liquidity sink, if they believe they can recycle liquidity from the other, unaffected system. They are more likely to risk a liquidity sink if they believe banks in the unaffected system will continue making payments early, unaware of the operational problem. I show that a liquidity-saving mechanism (LSM) in one system may reduce the probability of spillover into the other; in this sense, I identify a positive externality from the introduction of an LSM.     

Real liquidity and banking

In an economy where banks take numeraire goods, so called money, as deposits, money allows depositors suffering preference shocks to withdraw from banks prematurely without liquidation of real investment. If real liquidity, defined as the real value of the monetary base, is low, the amount of payment liquidity, constrained by the velocity of money, limits the short-term price level of investment goods before banks can settle their long-term loan contracts. This leads to an attractive nominal long-term investment return and over-investment. Allowing for inside money, that is, bank deposits, to be used for payment can improve social welfare but cannot fully resolve the liquidity shortage problem as the short-term interest rate offered by banks is constrained by the threat of bank runs. In the presence of systemic liquidity shocks, the price-adjustment mechanism cannot take full effects with insufficient payment liquidity, which can lead to non-zero profits for banks. Exchanging investment goods for numeraire goods through international trade can improve social welfare.     

Liquidity risk and policy options

On the basis of a liquidity management model, liquidity risks, defined as the probability of payment failures in a real-time gross settlement (RTGS) payment system, may either stem from liquidity management inefficiencies or insufficient cash balances. I will show that penalties charged on the amount of payment failures minimise liquidity risks without interfering with the bank’s technology preferences. I will instead show that liquidity requirements, although as effective as penalties to contain the risk of liquidity shortage, may distort the bank’s technology preferences and cannot stem liquidity management inefficiencies. I will also show that liquidity risks within RTGS payment systems are potentially smaller because they depend more on the liquidity management efficiency than on the randomness of cash inflows and outflows.     

What is in it for us? Network effects and bank payment innovation

The developed world exhibits substantial but poorly understood differences in the efficiency and quality of low value payment services. This paper compares payment arrangements in the UK, Norway, Sweden, and Finland, and discusses the impact of network effects on incentives to adopt new payments technology. A model is presented, in which private benefits for investment in shared inter-bank payments infrastructure are weak. In contrast, due to ‘account externalities’, there are strong incentives for investment in intra-bank payment systems. These two features, distinguishing bank payments from other network industries, can help explain some of the observed cross-country differences in payment arrangements.     

An Experiment on Retail Payments Systems

We develop a novel theoretical and experimental framework to study adoption and use of cash versus electronic payments in retail transactions. The design allows us to assess the behavioral impact of sellers' service fees and buyers' rewards from using electronic payments. In the experiment, buyers and sellers faced a coordination problem, independently choosing a payment method before trading. Sellers readily adopted electronic payments but buyers did not. Eliminating service fees or introducing rewards significantly increased adoption and use of electronic payments. Buyers' economic incentives were crucial for the diffusion of electronic payments but cannot fully explain their adoption choices.     

Payment obligations,reserve requirements,and the demand for central bank balances

We develop a model in which a bank's demand for reserves depends on the joint distribution of transactions, reserve requirements, and the interest rate. By devoting resources to its liquidity management, a bank can save on costly reserves required to settle its payments on time. We test the model with data from the largest banks in the Swiss Interbank Clearing system. We find that the turnover ratio (the speed with which a bank turns over its reserves in the payment system) depends largely on the aggregate value of its payments. We also find that reserve requirements impose a highly uneven burden on the banks.     

Price incentives and consumer payment behaviour

In this paper we estimate the effect of particular price incentives on consumer payment patterns using transaction-level data. We find that participation in a loyalty program and access to an interest-free period tend to increase credit card use at the expense of alternative payment methods, such as debit cards and cash. Interestingly though, the pattern of substitution from cash and debit cards differs according to the price incentive. An implication of the findings is that the Reserve Bank reforms of the Australian payments system are likely to have influenced observed payment patterns.     

Payments Settlement: Tiering in Private and Public Systems

What are the benefits provided by a payment system? What are the trade‐offs in public versus private payment systems and in restricted versus open payments arrangements? Modern payment systems encompass a variety of institutional designs with varying degrees of counterparty protection. We develop a framework that allows for an examination and comparison of payment systems, and specification of conditions leading to their adoption. We relate these conditions to the design of present large‐value payment systems (Fedwire, CHIPS, TARGET, etc.).     

Does better information about foreign shocks improve monetary policy?

This paper examines whether better information about foreign shocks leads to welfare-improving monetary policy using a stylised two-country New Keynesian general equilibrium model. We demonstrate that when terms of trade externality exist and national central banks have the incentives to shift terms of trade in their own favour, the equilibrium under imperfect information may be welfare superior relative to an equilibrium with perfect information. In addition, the welfare gains or losses from information sharing between central banks are found to be small for empirically plausible range of parameters for risk aversion and elasticity of labour supply.

Precautionary Demand and Liquidity in Payment Systems

In large‐value real‐time gross settlement payment systems, banks rely heavily on incoming funds to finance outgoing payments. Such reliance necessitates a high degree of coordination and synchronization. We construct a model of a payment system calibrated for the U.S. Fedwire system and examine the impact of realistic disruptions motivated by the recent financial crisis. In such settings, individually cautious behavior can have a significant and detrimental impact on the overall functioning of the payment system through a multiplier effect. Our results quantify the mutually reinforcing nature of greater caution, and allow comparative statics analysis of shifts in key parameters.     

Continuance intention of baby boomer and X generation as new users of digital payment during COVID-19 pandemic using UTAUT2

The emergence of social distancing and stay at home regulations during the COVID-19 pandemic directly affects people’s lifestyle, including baby boomers and X generation. Many of them have started using digital payments for online or offline transactions to minimize contact with others. This study aims to analyze the continuance intention of the baby boomers and X generation toward the use of digital payments using UTAUT2 (Unified Theory of Acceptance Technology). Data were collected from 320 users with an age range of 40–74 who had just started using digital payments during this pandemic. Structural equation modeling has been used to analyze the data. The result indicates that UTAUT indicators positively affect user satisfaction. User satisfaction positively affects inertia. Overall satisfaction and inertia positively affect continuance intention. Therefore, digital payment companies and banks with digital services can expand their target market beyond Millennials and pay more attention to the older generation like baby boomers and X generation. Managers can find the results of this study useful and beneficial to develop their marketing strategy and take advantage of this situation to increase digital payment users to a broader age range.

     

Quantifying equilibrium network externalities in the ACH banking industry

We seek to determine the causes and magnitudes of network externalities for the automated clearing house (ACH) electronic payments system. We construct an equilibrium model of customer and bank adoption of ACH. We structurally estimate the parameters of the model using an indirect inference procedure and panel data. The parameters are identified from exogenous variation in the adoption decisions of banks based outside the network and other factors. We find that most of the impediment to ACH adoption is from large customer fixed costs of adoption. Policies to provide moderate subsidies to customers and larger subsidies to banks for ACH adoption could increase welfare significantly.     

Assessing financial instability: The case of Brazil

In this paper we use the arbitrage pricing theory to infer the probability of financial institution failure for banks in Brazil. We build an index of financial stability for Brazilian banks. Empirical results seem to provide evidence that after the Russian crisis in 1998, systemic risk has increased in the country but this risk has decreased over time through 2002. Furthermore, for individual major banks the probability of failure has decreased monotonically after the Russian crisis with the adoption of a floating exchange rate regime, an inflation-targeting framework and the introduction of the new payment system.
