Liquidity management of foreign exchange reserves in continuous time

In order to cope with daily foreign currency exchange payments or trades and avoid liquidity crisis, central banks need to maintain the liquidity of foreign exchange reserves. In this paper, we develop a Foreign Exchange Reserves Liquidity Management (FERLM) model based on stochastic process by introducing a foreign exchange factor. We also generate a feasible target proportion of the liquidity reserve to total foreign exchange reserves, by seeking the balance between capital gains of holding foreign exchange reserves and losses of liquidity insufficiency.     

LIQUIDITY,MONEY CREATION AND DESTRUCTION,AND THE RETURNS TO BANKING*

We build on our earlier model of money in which bank liabilities circulate as a medium of exchange. We investigate optimal bank behavior and the resulting provision of liquidity under a range of central bank regulations. In our model, banks issue inside money under fractional reserves, facing the possibility of excess redemptions. Banks consider the float resulting from money creation and make reserve‐management decisions that affect aggregate liquidity conditions. Numerical examples demonstrate positive bank failure rates when returns to banking are low. Central bank interventions may improve banks' returns and welfare through a reduction in bank failure.     

Asset-based Reserve Requirements: Some Reservations

Abstract

Thomas Palley's (2004) paper ‘Asset-based reserve requirements: reasserting domestic monetary control in an era of financial innovation and instability’ has radical implications for monetary policy and the operations of central banks in the money markets. This comment argues that Palley's proposal may be impractical today because it overlooks banks' holding of excessive reserves (or claims on such reserves), and because reserves allocated for particular kinds of business cannot be isolated in bank balance sheets or markets. In particular, once differential reserves are imposed on particular kinds of business, banks may respond to changes in reserve requirements by varying their assets in less predictable ways than the scheme suggests. A central bank's willingness to use differential reserve requirements will be inhibited by the current policy doctrine that emphasises control of a stable money market rate of interest. In any case, it is doubtful if interest rates or reserve requirements could have the specific targeted effects that Palley's model suggests.     

Monetary policy under a multiple-tool environment

Since the 2008 global financial crisis, central banks have been using a new set of policy tools in addition to conventional tools (such as short-term interest rates) to conduct monetary policy. This paper employs a methodology that captures 25 of these tools with a limited number of factors for Turkey. Due to a set of factors such as the high volatility of inflation, market-friendly financial architecture and its size, Turkey provides a unique environment to capture these factors and their effects on economic performance. The three factors identified here can be categorized as interest rate, central bank foreign exchange position and liquidity. The empirical evidence reveals that these three factors affect all the economic-state variables considered in the paper in different directions and magnitudes.     

Eliminating Required Reserves: Does it Matter?

The Government of Canada has recently announced its intention to eliminate reserve requirements at the chartered banks. This paper investigates whether required reserves are relevant for economic stabilization, using a prototype macro model characterized by both contemporaneous and legged bank reserve accounting. It is shown that required reserves have no affect on economic stability as long as the central bank can set the interest elasticity of the supply of bank reserves. This adjustment depends on the reserve accounting system in effect at the time of the regime shift. [431]     

Policy Measures to Alleviate Foreign Currency Liquidity Shortages under Aggregate Risk with Moral Hazard

During the recent global financial crisis, certain central banks introduced two innovative cross‐border operations to deal with the problems of foreign currency liquidity shortages: domestic liquidity operations using cross‐border collateral and operations that supply foreign currency among central banks based on standing swap lines. We show theoretically that central banks improve the efficiency of equilibrium under foreign currency liquidity shortages using these two innovative temporary policy measures.     

The ‘compensation’ thesis,as exemplified by the case of the Chinese central bank

This paper extends the theory of demand-led money supply endogeneity to the case of an open economy with a fixed exchange rate. This theory is contrasted to the standard Mundell-Fleming view. In the compensation approach advocated here, central banks are able to set interest rates, even in a fixed exchange rate regime, either because there are automatic market mechanisms that will induce the private sector to act in such a way that changes in foreign reserves will be compensated by opposite changes in central bank claims over the domestic economy, or because the central bank will engage in endogenous sterilization operations in its efforts to enforce its benchmark interest rate. Analyzing the balance sheet of the Chinese central bank, we find that the large rise in foreign reserves on the asset side is compensated by large positive changes in items of the liability side, mainly bonds issued by the central bank. Foreign reserves are not cointegrated with the monetary base, meaning that there is no long-run relationship between foreign exchange reserves and the supply of base money. We also find no long-run relation between foreign exchange reserves and the consumer price index.     

Bank lending and interest on excess reserves: An empirical investigation

This paper econometrically tests for effects on bank lending of the Federal Reserve’s policy of paying interest on excess reserves (IOER). Following the 2008 financial crisis, US banks decreased their loan allocations and increased holdings of excess reserves. A model of bank asset allocation shows that when the rate of IOER is higher than other short-term rates, banks will switch from zero excess reserves to a regime with higher excess reserves and lower lending. Using a sample of panel data on US banks from 2000 through 2018, we find evidence of a switch to a positive excess reserve regime in the post-crisis period. Controlling for market interest rates, loan demand, and economic activity, we find that IOER accounts for the majority of the decline in bank lending after the financial crisis.     

ON THE WELFARE PROPERTIES OF FRACTIONAL RESERVE BANKING

Monetary economists have long recognized a tension between the benefits of fractional reserve banking, such as the ability to undertake more profitable (long‐term) investment opportunities, and the difficulties associated with it, such as the risk of insolvency for each bank and the associated losses to bank liability holders. I show that a specific banking arrangement (a joint‐liability scheme) provides an effective mechanism for ensuring the ex post transfer of reserves from liquid banks to illiquid banks, so it is possible to select a socially efficient reserve ratio in the banking system that preserves the safety of bank liabilities as a store of value and maximizes the rate of return paid to bank liability holders.     

准备金制度功能的异化与我国准备金政策的取向

"利率走廊"调控是当前国际最新的利率调控范式,加拿大等国在"利率走廊"调控基础上,实行零准备制度,这使人们误认为准备金制度似乎走到头了.实际情况并非如此,其实行零准备金并非抛弃准备金制度,而是在利率调控的新背景下,以准备金为零的制度.它的机制和功能与传统准备金制度有很大的异化,但是却代表着准备金制度发展演变的趋势.所以研究准备金制度功能异化的动因,以及它未来的变动趋势,对于我国准备金制度的规范完善具有重要的借鉴意义.     

Cross-country differences in monetary policy execution and money market rates’ volatility

Volatility patterns in overnight interest rates display differences across industrial countries that existing models—designed to replicate the features of individual countries’ markets—cannot account for. This paper presents an equilibrium model of the overnight interbank market that matches cross-country differences in patterns in interest volatility by incorporating differences in how central banks manage liquidity in response to shocks. Our model is consistent with central banks’ practice of rationing access to marginal facilities when the objective of stabilizing short-term interest rates conflicts with another high-frequency objective, such as an exchange rate target.     

What Do Data Say About Monetary Policy,Bank Liquidity and Bank Risk Taking?

This paper tests empirically the linkage between banks' investment and interbank lending decisions in response to interest rate changes. We draw conclusions for the monetary policy, which uses the interest rate as its main tool. Across European countries we find that the risk-free (i.e. monetary policy) interest rate negatively affects the liquidity retained by banks and the decision of a bank to be a lender in the interbank market. Instead, the interbank interest rate has a positive impact on these decisions. We also find that banks who lend show less risk-taking behaviour and tend to be smaller than those who are borrowers. Most importantly, the risk-free interest rate is positively correlated with loans investment and bank risk-taking behaviour.     

Over- and Underbidding in Central Bank Open Market Operations Conducted as Fixed Rate Tender

Abstract. Open market operations play a key role in allocating central bank funds to the banking system and thereby in steering short‐term interest rates in line with the stance of monetary policy. Many central banks apply so‐called ‘fixed rate tender’ auctions in their open market operations. This paper presents, on the basis of a survey of central bank experience, a model of bidding in such tenders. In their conduct of fixed rate tenders, many central banks faced specifically an ‘under‐’ and an ‘overbidding’ problem. These phenomena are revisited in the light of the proposed model, and the more general question of the optimal tender procedure and allotment policy of central banks is addressed.

Commercial bank ownership and performance in China

This study examines the determinants of bank performance based on proxy variables that assess the quality of assets, profitability, liquidity and overall performance. Using a sample of 111 Chinese commercial banks over the period of 2000–2012, we find that foreign banks appear to have better asset quality and overall performance although lower profitability compared to domestic banks. In contrast, the state-owned banks tend to be more profitable and have better liquidity position compared with other domestic banks and foreign banks. At bank level, equity/liability ratio exerts significant influence on overall bank performance, while at the macroeconomic level, per capital GDP, GDP growth, inflation and unemployment rates appear to have a bearing on bank performance.     

The link between the federal funds rate and banking system distress: An empirical investigation

We investigate the association between deviations of the monetary policy rate from its benchmark, and systemic risk between 2001 and 2017. We adopt an impulse response function framework that uses the local projections method model proposed by Jorda (2005). We find that paying interest on reserves by the Fed beginning in 2008 introduced a monetary policy regime shift between the period that the Fed did not pay interest on reserves and the period that it did. Consequently, while we identify a positive and significant link between deviations of the policy rate from its benchmark and systemic risk in the former period, this link was broken in the latter period. During the former period, upsurges in the fed funds rate raised bank costs and increased bank distress. In contrast, during the latter period, interest payment on reserves exceeded the policy rate, except for 2009Q1, and as a result, banks did not expand lending in response to the Fed's reserve injections, instead, holding large amounts of excess reserves. This practice produced greater bank profitability and reduced bank liquidity risk and credit risk, without increasing systemic risk.     

Lenders on the storm of wholesale funding shocks: saved by the central bank?

We provide empirical evidence on banks’ responses to shocks in the wholesale funding market, using data of 181 euro area banks over the period from August 2007 to June 2013. Responses to funding liquidity shocks for both banks’ lending volumes and loan rates, to households and corporates, are analysed in a panel VAR framework. We thereby distinguish banks by country, extent of Eurosystem borrowing, bank size and capitalization. The results show that shocks in the securities and interbank markets have significant effects on loan rates and credit supply, particularly of banks in stressed countries of the periphery. The results also suggest that central bank liquidity has mitigated this effect on lending volumes. Lending to nonfinancial corporations is more sensitive to wholesale funding shocks than lending to households. Lending volumes of large banks that are typically more dependent on wholesale funding and banks with large exposure to sovereign bonds show stronger responses to wholesale funding shocks.     

央行票据调控可持续性分析

央行票据是中央银行为调节商业银行超额准备金而向商业银行发行的短期债务凭证,是中央银行为调节商业银行流动性而出台的一项货币政策工具,其实质是中央银行债券。目前,央票已经是债券市场不可或缺的短期投资工具和流动性管理工具。但伴随中国经济增长趋势的放缓,央行票据发行规模的下降,央票是否继续存在的争论也由此而起。通过分析我国央行票据的发展情况及现状,对央票调控的利弊进行分析,并为央票存在的持续性寻求合理的理论支持。     

Interest on Reserves and the Flexibility of Monetary Policy in the Euro Area

This paper shows that remunerating required reserves can increase the flexibility of monetary policy. The remuneration at the current policy rate implies constant net marginal interest costs of holding required reserves. This allows the central bank to change the policy rate also within a reserve maintenance period without inducing a problematic reserve shifting on behalf of the banks. In the euro area, required reserves are remunerated at an average rate. Therefore, the way in which reserves are remunerated has to be changed in order to make use of the advantage of a higher flexibility of monetary policy.     

Macroeconomic adjustment with managed exchange rates and capital controls: Some lessons from China

This paper examines the performance of capital controls and exchange-rate management when the economy finds itself in dark corners. These are times when the real sector experiences a sequence of prolonged negative shocks from world demand, while the central bank faces low world interest rates on its foreign-exchange reserve holdings. We examine two regimes, one of a fixed exchange rate with strong capital controls and another with a more open capital account with a managed exchange rate. We show how this model replicates recent experiences of China as it moved from a relatively fixed exchange rate regime with strong capital controls to a more flexible exchange rate regime with a more open capital account. Our results show that capital-account liberalization should be accompanied by domestic price liberalization to avoid large losses in foreign exchange reserve and jumps in unemployment during dark corners in the more open regime.
