中国外汇储备对货币政策的影响

20世纪90年代中期以来,我国外汇储备在国际收支双顺差和外汇管理体制改革的推动下超常增长,并成为制约货币政策有效性的重要因素。本文从理论上阐明了在开放经济条件下,外汇储备与货币政策的内在逻辑联系;从实证角度剖析了外汇储备变动对我国货币政策调控的冲击,以及引起汇率政策与货币政策的冲突。我国应改革现行的外汇管理制度,加大公开市场业务操作力度,促使国际收支结构平衡,以提高货币政策实施的自主性和灵活性。     

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.     

我国外汇存款准备金问题研究

2007年美国次贷危机爆发后,全球性的流动性过剩被流动性不足所替代,美国政府采取了扩张性的政策组合,即以降息和提供紧急流动性援助方式为代表的扩张性货币政策、以减税为代表的扩张性财政政策以及纵容美元贬值的汇率政策,以对中国经济政策的调整空间形成制约.我国中央银行上调外汇存款准备金率以及要求用外汇缴存新增人民币存款准备金的做法,并不能从根本上缓解人民币汇率的升值压力,相关的外汇存款准备金制度设计还有待改进.     

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.     

Bank competition and optimal monetary policies under alternative reserve accounting schemes

The purpose of this paper is to provide a theoretical analysis of the implications of increased competition among depository financial institutions for the optimal conduct of monetary policy with respect to the ultimate goals of price and output stability. In the context of a general equilibrium model which includes rational expectations and a market for bank deposits, it is shown that a rise in bank rivalry for deposits produces a more steeply sloped LM schedule. Under a system of lagged required reserve accounting, this fact has no effect on the optimal conduct of monetary policy, which requires an operating procesure designed to target a market interest rate. However, under a system of contemporaneous reserve accounting, this fact implies that less emphasis should be placed on a market interest rate as a variable upon which the Fed's setting of reserves should be conditioned.     

货币政策工具与中介目标选择:基于法定准备金操作的研究

利率和货币量哪个更适合作为货币政策中介目标是一个很有争议的问题,目前许多文献对这个问题的研究并不涉及货币政策工具与利率以及货币量之间的关系。这样的研究实际上隐含了一个前提,即货币政策工具和利率以及货币量之间存在明确的、稳定的关系,从而保证利率目标或者货币量是可控的。基于法定准备金操作的研究表明,法定准备金操作和货币量之间存在确定的关系,而和利率之间的关系是不确定的。导致利率和法定准备金操作关系不确定的主要原因,则是IS曲线斜率正负性的不确定性;同时,对现阶段中国IS曲线斜率稳定性的实证研究表明,其斜率正负性是不稳定的。因此,利率不适合作为货币政策中介目标。     

Surplus liquidity,central bank losses and the use of reserve requirements in emerging markets

Since the turn of the millennium, stocks of foreign reserves held by central banks in many emerging markets and developing countries have exceeded currency in circulation. To steer money market rates, these central banks have been absorbing liquidity from, rather than providing it to, the banking sector in their regular monetary policy operations. When interest rates in countries with major reserve currencies are low, the yield on foreign reserves is low. A higher interest rate on liquidity‐absorbing operations may expose central banks to losses. Although a central bank is not a profit‐maximizing institution, central bank losses can undermine the independence of the central bank. Using data for a large panel of central banks, this paper provides some evidence that central banks tend to apply low‐remunerated reserve requirements when profitability is at stake.     

The credit squeeze during Russia's early transition: A bank-based view

This paper asks whether Russia's protracted inflation stabilization might have caused a credit squeeze and hence might have contributed to the output collapse in the first three years of the Russian transition. Russian monetary policy was not restrictive as a whole. Still, the occurrence of a credit crunch is not excluded, because of the Russian central bank's heavy reliance on required reserves to curb the inflationary effects of monetized budget deficits. Due to methodological limitations, we are forced to concentrate on a cross-sectional analysis of bank liquidity in 1994, in order to find possible indications about Russia's monetary stance from the point of view of the lending channel. We cannot reject that the huge excess reserves of Russian banks in 1994 were at least partially due to excess liquidity. This suggests that there is no direct relation between the monetary policy of high required reserves and the observed credit crunch. The question of why banks preferred to hold excess liquidity deserves further attention. This question is still relevant, because Russian commercial banks have again accumulated excess reserves in 1999, in the aftermath of the banking crisis, triggered by the August-1998 crisis.     

The “Impossible Trinity” Hypothesis in an Era of Global Imbalances: Measurement and Testing

We outline new metrics for measuring the trilemma aspects: exchange rate flexibility, monetary independence, and capital account openness, taking into account substantial international reserve accumulation that has taken place since the 2000s. Since 1990, the trilemma variables in emerging markets have converged towards intermediate levels, characterizing by managed flexibility, using sizable international reserves as a buffer while retaining some degree of monetary autonomy. We test the linearity of the trilemma, and find that the weighted sum of the three trilemma variables adds up to a constant. Thus, a rise in one trilemma variable should be traded‐off with a drop of the weighted sum of the other two.     

The Impacts of Financial Integration on the Linkages Between Monetary Independence and Foreign Exchange Reserves

This paper investigates the short-run and long-run effects of financial integration on the dynamics between monetary independence and foreign exchange reserves using a GMM system estimation involving two-year non-overlapping average data (2000-2011) from 114 countries. The results indicate that the effect of foreign exchange reserves on the monetary independence is intensified by the level of financial integration. This suggests a positive spill over effect from the financial integration to the monetary policy independence. Besides, a positive implication of financial integration on monetary independence could be established when the foreign exchange reserves is at the maximum level. In addition, the comparisons between the mean of foreign exchange reserves and the threshold levels of foreign exchange reserves that neutralise the impact of financial integration indicate that on average, the foreign exchange reserves are sufficient to offset the effect of financial integration. A stable exchange rate will undermine the positive impact of foreign exchange reserves on monetary independence. Finally, the long-run and short-run impacts occur in the same direction. This paper ends with some policy implications and suggestions for future research.     

Inflation targeting and exchange rate volatility smoothing: A two-target,two-instrument approach

This paper introduces a strategy to model a small open economy, whose central bank has established two simultaneous policy objectives: an inflation target, and a maximum limit for nominal exchange rate volatility. In line with the Tinbergen–Aoki condition, the monetary authority establishes two policy instruments, one for accomplishing each target: the monetary policy rate, and the stock of foreign exchange reserves. Monetary policy analysis is built around a non-microfounded augmented New Keynesian DSGE model estimated through Bayesian techniques for the Guatemalan economy. It is found that each instrument is efficient in accomplishing its own target. Nevertheless, a coordinated effort is required for central bank policymakers before employing both instruments simultaneously, in order to avoid sending mixed signals to economic agents about its monetary policy stance, and endanger the achievement of its inflation target.

The monetary autonomy of Finland: What can the time series analysis tell us?

The effectiveness of domestic monetary policy under fixed exchange rates is highly dependent on the response of the foreign exchange reserves to a monetary expansion or contraction. Domestic monetary conditions, in turn, can be expected to be subject to shocks emerging from changes in reserves. These shocks can badly harm stabilization objectives if they are not neutralized. This paper analyzes the monetary autonomy of the Finnish economy during the 1970's and early 1980's using a data-oriented approach suggested byGeweke. A purely empiristic interpretation of the results would indicate that the degree of monetary autonomy is high and increasing over time. However, incorporating theoretical considerations turns this conclusion upside down. The Finnish financial system has in all likelihood experienced structural changes that have reduced the potential for effective monetary policies. On the other hand, we do not find any evidence of strong effects of reserve shocks on the domestic money and credit markets, though the importance of such shocks may have increased slightly. Methodologically, the analysis highlights that economic theory is needed in organizing empirical observations even when the point of departure is data-oriented.     

Involuntary excess reserves,the reserve requirements and credit rationing in China

Using a sample of 95 banks that covers the period 2000–2011, this article examines Chinese banks’ credit lending behaviour in response to the changes in the reserve requirement ratio in the presence of involuntary excess reserves (IERs) in the banking system. The study finds that Chinese banks with positive IERs one period after a reserve requirement shock experience a significantly increased credit supply in response to an increase in reserve requirement ratio. However, the reserve requirements have no significant impact on the credit supply in Chinese banks that have negative IERs one period after a reserve requirement shock. This article sheds lights on the effectiveness of Chinese monetary policy, which uses reserve requirements as the primary tool to sterilize excess liquidity and restrain credit expansion.     

汇率-资本流动性的制度安排和财政-货币政策的有效性研究

笔者通过拓广的蒙代尔-弗莱明模型,并突破了传统的"三元冲突"汇率制度安排理论的研究路径,考虑引入资本流动性相对强度系数的概念,又在固定汇率制下引入"冲销"干预政策因素,提出了一个在固定和浮动汇率及不同资本流动性制度安排下财政-货币政策有效性指数曲线的新假说,对汇率-资本流动性制度安排对于宏观经济政策(财政-货币政策)综合有效性的影响问题做了一些较为深入的探讨.笔者认为,我国作为一个经济大国应尽可能地拥有宏观经济政策的自主权,考虑到我国当前金融市场体系尚不够完善,货币政策传导机制还存在严重障碍,所以在近期财政政策的权重应大于货币政策,从而在我国汇率制度改革过程中,为保留宏观经济政策的自主权,在加快放宽人民币汇率弹性的同时必须加强相应的资本管制.

本文采用修正的BGT模型,实证研究了国际资本流动影响因素以及央行在面对国内外资本市场波动、金融体系变迁等情形下,货币政策实施方式及其效果。结果显示,随着意愿结售汇制度的实行和人民币汇率弹性的增强,央行的货币自主性得以加强;在开放环境下,国际资本流动受国内外利差、资本市场溢价、货币政策及汇率制度和外汇管理制度的影响。面对这些国内外冲击,央行进行了央票冲销或调整准备金率等的反向货币政策操作,以实现货币政策目标。     

Reserve requirement, reserve requirement tax and money control in China: 1984–2007

In recent years, the People’s Bank of China (PBC) has carried out monetary policy by means of reserve requirement frequently in an effort to hedge the excess liquidity in the banking system. But just like other government taxes, reserve requirement maybe have an optimal required reserve rate (RRR). When the RRR have been raised to the optimal level, the effect of reserve requirement policy in money control and liquidity sterilization should also be withered due to the loss of the “tax base”. Therefore, we establish a theoretical model and analysis framework and make the corresponding econometric test and empirical analysis. The main conclusions are as follows: The optimal RRR in China at present is about 23%. If the RRR is further raised above 23%, the monetary authority should adjust the deposit and loan interest rates, interest margins between deposits and loans and the deposit reserve requirement rate to expand the using scope of the reserve requirement policy. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2008, (10): 37–51

Reserve requirements and the bank lending channel in China

This paper examines how reserve requirements influence the transmission of monetary policy through the bank lending channel in China while also taking into account the role of bank ownership. The implementation of Chinese monetary policy is characterized by the reliance on the reserve requirements as a regular policy tool with frequent adjustments. Using a large dataset of 170 Chinese banks for the period 2004–2013, we analyze the reaction of loan supply to changes in reserve requirements. We find no evidence of the bank lending channel through the use of reserve requirements. We observe, nonetheless, that changes in reserve requirements influence loan growth of banks. The same findings hold true for other monetary policy instruments. Further, we show that the bank ownership format influences transmission of monetary policy.
