Money and liquidity in financial markets

We argue that there is a connection between the interbank market for liquidity and the broader financial markets, which has its basis in demand for liquidity by banks. Tightness in the market for liquidity leads banks to engage in what we term “liquidity pull-back,” which involves selling financial assets either by banks directly or by levered investors. Empirical tests on the stock market are supportive. Tighter interbank markets are associated with relatively more volume in more liquid stocks; selling pressure, especially in more liquid stocks; and transitory negative returns. We control for market-wide uncertainty and in the process also contribute to the literature on portfolio rebalancing. Our general point is that money matters in financial markets.     

Safe Assets as Commodity Money

This paper presents a model in which safe assets are systemic because they are the medium of exchange in risky assets. It connects the literature from banking and finance on safe assets to the monetary literature on alternative monetary systems involving commodity money, interest bearing money, and private money creation. Because safe assets have intrinsic value, changes in their supply lead to changes in market efficiency. Additionally, because safe assets are costly to produce, there is overproduction of safe assets relative to the social optimum. When the model is calibrated to plausible liquidity premiums the resulting inefficiencies are not large.     

The impact of the global financial crisis on the cross-currency linkage of LIBOR–OIS spreads

This article examines the impact of global financial crisis on cross-currency linkage of the LIBOR–OIS spread, a financial stress measure in interbank markets. The impulse response analysis is conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. The overall evidence suggests that the crisis has substantially changed the nature of the cross-currency interactions in liquidity stress. Also global money markets have failed to contain stress in US dollar funding and the role of the Japanese yen as a liquidity source appears to be significant, while these two currencies drive the cross-currency system of liquidity stress.     

Deposit insurance, bank regulation, and financial system risks

Empirical evidence is presented to show that in modern times banks can hedge liquidity shocks but could not do so prior to FDIC insurance. However, the government's limitations in properly pricing FDIC insurance are leading to many current examples of moral hazard. A model is presented to show that if insurance premiums are set to be “actuarially fair,” incentives for banks to take excessive systematic risks remain. Motivated by empirical evidence that money market mutual funds also can hedge liquidity shocks, I consider an alternative government insurance system that mitigates distortions to risk-taking yet preserves liquidity hedging and information synergies.     

德国利率市场化改革的特点与其金融业发展

利率市场化是指金融机构在货币市场经营融资的利率由市场供求来决定,它包括利率决定、利率传导、利率结构和利率管理的市场化。文章考察了德国利率市场化改革的特点及其对金融业发展的积极影响。德国利率市场化改革分步骤平稳推进。改革后,在全能银行模式下德国金融业没有出现象美、英那样的银行集中倒闭危机;银行贷款在非金融部门融资中仍居于主导地位,而住户部门的金融资产结构发生显著变化;德国的货币政策主要是通过改变银行的流动性来影响金融市场利率,进而间接影响银行信贷政策以及实体经济。     

Monetary policy and covered interest parity in the post GFC period: Evidence from the Australian dollar and the NZ dollar

After the global financial crisis (GFC), most major currencies had higher interest rates than the US dollar on forward contract because of increased demand for the US dollar as international liquidity. However, unlike the other major currencies, the Australian dollar and the NZ dollar had lower interest rates than the US dollar on forward contract in the post GFC period. The purpose of this paper is to explore why this happened through estimating the covered interest parity (CIP) condition. In the analysis, we focus on a unique feature of Australia and New Zealand where short-term interest rates remained significantly positive even after the GFC. The paper first constructs a theoretical model where increased liquidity risk causes deviations from the CIP condition. It then tests this theoretical implication by using daily data of six major currencies. We find that both money market risk measures and policy rates had significant effects on the CIP deviations. The result implies that unique monetary policy feature in Australia and New Zealand made deviations from the CIP condition distinct on the forward contract.

Financial Innovations,Money Demand,and the Welfare Cost of Inflation

In the 1990s, the empirical relationship between money demand and interest rates began to fall apart. We analyze to what extent financial innovations can explain this breakdown. For this purpose, we construct a microfounded monetary model with a money market that provides insurance against liquidity shocks by offering short‐term loans and by paying interest on money market deposits. We calibrate the model to U.S. data and find that the introduction of the sweep technology at the beginning of the 1990s, which improved access to money markets, can explain the behavior of money demand very well. Furthermore, by allowing a more efficient allocation of money, the welfare cost of inflation decreased substantially.     

Currency carry trade regimes: Beyond the Fama regression

We show that carry trade strategies resemble FX option strategies that sell out of the money puts on high interest rate currencies. Both strategies collect premiums to generate persistent excess returns that unwind sharply when volatility increases. We also show that the widely documented negative slope coefficient in regressions of exchange rate depreciation on forward currency premiums is an artifact of the volatility regime. In high volatility regimes, the so-called Fama regression produces a positive coefficient greater than unity. We finally document the existence of an intuitive co-movement between currency risk premiums and yield curve risk factors.     

Money,Asset Prices,and the Liquidity Premium

This paper examines the effect of monetary policy on the market value of the liquidity services that financial assets provide, known as the liquidity premium. The theory predicts that money supply and nominal interest rates have positive effects on the liquidity premium, but asset supply has a negative effect. The empirical analysis with U.S. data confirms the theoretical predictions. The theory also proposes that the liquidity properties of assets can cause negative nominal yields when the money holding cost is low and liquid assets are scarce. The suggestive empirical findings in Switzerland to support this theoretical result are presented.     

Properties of foreign exchange risk premiums

We study the properties of foreign exchange risk premiums that can explain the forward bias puzzle, defined as the tendency of high-interest rate currencies to appreciate rather than depreciate. These risk premiums arise endogenously from the no-arbitrage condition relating the term structure of interest rates and exchange rates. Estimating affine (multi-currency) term structure models reveals a noticeable tradeoff between matching depreciation rates and accuracy in pricing bonds. Risk premiums implied by our global affine model generate unbiased predictions for currency excess returns and are closely related to global risk aversion, the business cycle, and traditional exchange rate fundamentals.

Investigating risk contagion initiated by endogenous liquidity shocks: evidence from the US and eurozone interbank markets

This paper investigates liquidity spillovers between the US and European interbank markets during turbulent and tranquil periods. We show that an endogenous model with time-varying transition probabilities is effective in describing the propagation of liquidity shocks within the interbank market, while predicting liquidity crashes characterised by changed dynamics. We show that liquidity shocks, originating from movements of the spread between the Asset Backed Commercial Paper and T-bill, drive regime changes in the euro fixed-float OIS swap rate. Our results support the idea of endogenous contagion from the US money market to the eurozone money market during the global financial crisis.     

Interbank market failure and macro-prudential policies

This paper analyses the effects of several macro-prudential policy measures on the banking sector and its linkages to the macroeconomy. We employ a dynamic general equilibrium model with sticky prices, in which banks trade excess funds in the interbank lending market. We find that an increase in the liquidity requirement effectively reduces the impact of an interbank shock on the real and financial sector, while an increased capital requirement propagates only through nominal variables as inflation and interest rates. We conclude that stricter liquidity measures which limit inside money creation, dampen the severity of a breakdown in interbank lending. Targeting interbank financing directly through liquidity measures along with a moderate capital requirement generates lower welfare losses. We thereby provide a comprehensive rationale in favor of the regulatory measures in Basel III.     

The information content of Eonia swap rates before and during the financial crisis

Before August 2007, implied forward rates in the overnight interest swap rates closely reflected market expectations about the future path of the Eonia, and therefore, about the future course of the ECB’s monetary policy stance. Nevertheless, this link was weakened considerably during the most acute episode of the financial crisis. Using the expectations hypothesis of the term structure as a benchmark model for the determination of the overnight interest swap rates, we find that after May 2010 the monetary transmission mechanism was partially restored when the ECB implemented various ‘unconventional measures’ in response to the financial crisis. On the contrary, liquidity and credit risks are still present in unsecured deposit markets, distorting the pricing and transmission of the ECB monetary policy stance along the Euribor rates. These results should be of interest for regulators, financial institutions, and researchers in European money markets.     

Substitution or complementary effects between banking and stock markets: Evidence from financial openness in Taiwan

This study uses quarterly data from 1973 to 2007 to investigate the influence of financial institutions on economic growth in Taiwan. We find that the breakpoint obtained by Gregory and Hansen (1996) appears in the third quarter of 1982, which coincides with the period of financial openness. In addition, the substitution effect between credit and equity markets is improved following financial openness. The negative impact of volatility on real output before financial openness turned positive after financial openness, suggesting that appropriate volatility enhances Taiwan's economic growth under the circumstance of more matured stock market following financial openness. However, the beneficial influence of liquidity on real output before financial openness turned negative afterward, suggesting openness generated the undesirable side effect of excess liquidity that impeded economic growth. Our long-run results are essentially the same even if we take the role of the private bond market into account.
