中国外汇冲销干预和货币政策独立性研究

2002年以来,中国国际收支"双顺差"加剧,外汇储备急剧增长,货币供应量增长,通货膨胀压力凸现。为了稳定人民币汇率和抑制通货膨胀,中央银行采取了一系列外汇冲销干预措施。文章在分析外汇冲销干预有效性理论的基础上,分析外汇储备急剧增长下外汇冲销干预的效力和制约因素,认为外汇冲销干预短期内能抵消外汇占款、控制信贷增长,但效力有限;在长期内,外汇冲销干预不仅会影响货币政策独立性,还可能导致通货膨胀、利率上升、汇率升值乃至经济"滞胀",因而难以具有可持续性,最后,文章提出加强外汇储备管理,增强外汇冲销干预效力和货币政策独立性的政策建议。     

外汇冲销式干预对中国货币政策独立性的影响研究

冲销干预对中国货币政策独立性的影响表现出长短期不一致的特征,在短期内有助于保持货币政策的独立性;但在长期内,冲销干预不仅会制约货币政策的操作空间,削弱其独立性,累积金融风险,导致恶性后果。对此,应优化央行票据的期限结构,完善以国债市场为核心的公开市场操作,发展外汇掉期交易,建立外汇平准基金制度,增强货币政策独立性。     

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。     

货币政策:“多目标”还是“单目标”——兼论通货膨胀目标制

货币政策有多目标与单目标之分,因目标之间的冲突,多目标的货币政策实际上是无效的,而单目标的货币政策可以做到目标明确。已有的例证—通货膨胀目标制被证明是相当成功的,我国应该创造条件,适时采用通货膨胀目标制,为经济发展创造良好的长期运行条件。     

Exchange Rates and Monetary Policy

This paper looks at the relation between exchange rates and monetary policy. It focuses in particular on the role of the exchange rate of the euro in the context of the ECB's monetary policy strategy. The objective of monetary policy is to maintain price stability. The euro area is a large and relatively closed economy. Therefore, the exchange rate of the euro is not an intermediate target nor is it an objective. Nevertheless, the ECB's stability–oriented monetary policy strategy does not neglect the exchange rate of the euro. Clearly, exchange rate developments are taken into account both when looking at the transmission mechanism of monetary policy and when assessing the current economic situation and prospects for the euro area.     

Foreign Policy and Ethnography: A Sceptical Intervention

This article makes a methodological argument about ‘studying up’ in foreign policy bureaucracies. Although recent years have witnessed a growing interest in ethnography across the social sciences, including the study of foreign policy and diplomacy, theoretical reflections on the methodology as such greatly outnumber those that actually attempt ethnographic accounts of foreign policy institutions. This imbalance results in large part from the difficulty of fieldwork in these settings. Drawing on six years of research on EU external relations, including 105 interviews with foreign policy professionals, this article lays out some of the difficulties and thereby clarifies the benefits and costs of such fieldwork. More broadly, the article highlights some of the methodological challenges in interpretative research inside the institutions of foreign policy. My concern is not with ethnography or foreign policy as such; I rather examine the specific challenges of conducting fieldwork informed by ethnographic methodology inside foreign policy bureaucracies. The article advises caution about the ever-widening use of the term ‘ethnography’ in the study of policy.     

人民币升值压力与货币政策:基于货币模型的实证分析

利用1994年1月至2008年1月的月度数据,采用外汇市场压力的货币模型,构建了人民币外汇市场升值压力指数,并利用向量自回归方法研究了中央银行国内信贷变化、中美相对经济增长率变化、中国利率水平变化与外汇市场压力之间的相互作用,探讨了美国基础货币增长、美国利率水平变化等外生变量对人民币升值压力的影响。发现中国中央银行国内信贷与人民币升值压力呈现负向关系,而中国经济增长和国内利率水平与人民币升值压力呈正向关系。当人民币升值压力增加时,货币当局的反应是减少其净国内信贷,而国内利率水平的变化则并不显著地反映人民币升值压力的变化。     

Fiscal Policy, Monetary Policy and the Exchange Rate

Domestic fiscal and monetary policy settings can influence the strength of the Australia dollar in a number of different ways.     

Money,Interest Rate and Foreign Exchange Rate As Indicator Variables Of Monetary Policy

Since monetary policy operations affect the ultimate targets such as real income and prices with considerable time lags, this papers attempts to identify the indicator variable of monetary policy in Korea by using autoregression tests, variance docompositions of VAR forecasts and cointegration analyses. The results show that in Korea unlike the U.S., a broad concept of money, interest rate and foreign exchange rate, taken together, could serve as the indicator variables. In particular, M3, But not M2 nor MCT, is significantly related to real income both in the short-run and in the long-run. Such a finding rejects the practice of controlling either M2 or MCT which the Korean monetary authority had exercised before implementing the recent IMF financial-reform program. [E5]     

主权财富基金、外汇储备管理与货币政策有效性

中国主权财富基金——中国投资公司的资产负债安排对国内银行体系流动性以及货币政策有效性具有负面影响。必须改革我国外汇储备管理体制:一是财政部应该介入外汇储备的管理;二是赋予中央银行更大的独立性,自主决定购买政府债券的时机和规模,切断外汇储备与银行体系流动性之间的对应关系。     

Monetary Policy in Australia: The Conflict between Short-Term and Medium-Term Objectives

This article argues that the recent implementation of monetary policy in Australia has been dominated by the response to a large range of unanticipated shocks. In the process of trying to minimise the adverse effects of such shocks, considerable uncertainty has been created about likely outcomes in the medium term. This makes medium-term objectives harder to achieve. Taking the reduction of inflation as an example of an appropriate medium-term objective, simulations are presented using the Murphy model of the Australian economy. The simulations demonstrate that a tightening of monetary policy will reduce inflation more slowly if private agents believe that the tightening is unlikely to be sustained for long. Under uncertainty, monetary policy will have to be tighter and real GDP significantly lower to achieve a given reduction in inflation. A confingency rule of medium complexity is suggested as one way in which appropriate medium-term objectives might be achieved while allowing some flexibility to react to unexpected outcomes in the short run.     

The Effects of Foreign Currency Derivatives on the Monetary Policy Exchange Rate Channel in China

This paper examines changes in the monetary policy exchange rate channel in the presence of foreign currency derivatives (FCD) markets in China. Initially a theoretical macroeconomics model incorporating the exchange rate risk hedging is presented, and this is followed by an empirical test. A theoretical model implies that with more firms using foreign currency derivatives to hedge the exchange rate risk, the effect of the exchange rate on the net exports will be weaker and may even be reversed. The empirical section uses Structure Vector Autoregression (SVAR) models with China's monthly macro data over the 2000–2013 period to assess the impact of the FCD market on the exchange rate channel. Empirical support for the changes in the exchange rate channel transmission is found. By impulse response function (IRF) analysis, with the emergence of the domestic FCD market in China, in the long run the probability becomes higher that the negative effect of RMB appreciation on China's net exports to the US is reversed; meanwhile the negative effects of RMB appreciation on the overall net exports and the net exports to the EU become gradually weaker on average.     

The Cost of Foreign Exchange Intervention: Concepts and Measurement

Foreign exchange intervention led to a sizable expansion of many central banks’ balance sheets over the last decade, raising questions about the associated fiscal costs. This paper clarifies conceptual issues about how to measure these costs both from an ex-post and an ex-ante (relevant for decision making) perspective, and estimates both marginal and total costs for 73 countries over the period 2002–13. Averaging across various estimation methods, we find ex-ante marginal costs in the inter-quartile range of 2.0–5.5% per year for emerging market economies. Reflecting differences in the accumulation of foreign exchange, ex-ante total costs amounted to 0.2–0.7% of GDP per year in countries with limited intervention, while reaching 0.3–1.2% of GDP per year in heavy-intervening economies. These estimates indicate that fiscal costs of sustained FX intervention are not negligible.     

我国外汇储备量及其构成对货币政策的影响分析

近几年我国外汇储备急剧增长,对我国货币政策产生了巨大影响。本文论证得出,我国近年货币政策调控压力与外汇储备的总量和构成密切相关,且其中热钱流入量与货币供给及调控压力相关性最高。据此给出建立外汇平准基金制度,完善多级式储备体系,对外汇储备实行分档管理和监控等政策建议。     

略论我国巨额外汇储备对从紧货币政策的影响

外汇储备作为一国经济金融实力的标志,它是弥补本国国际收支逆差、稳定本国汇率以及维持本国国际信誉的物质基础,但外汇储备并非多多益善.尤其对我国2008年开始实行的从紧货币政策而言,巨额的外汇储备导致的外汇占款会形成强大的压力,以至削弱货币政策的有效性.从我国外汇储备状况的现实入手,分析了我国外汇储备迅猛增长的原因及巨额外汇储备对我国从紧货币政策造成的压力.     

汇率制度与货币政策——发展中国家和小国经济的思考

本文中,我们将研究在资本市场对外开放及汇率固定条件下货币政策的管理机制问题。我们的目标是探讨货币政策能否在此种情况下继续独立而有效地稳定国内经济。为此,我们建议两种制度上的约束。给定这些约束,我们证明货币政策仍然有效。同时,本文讨论了此种制度选择对发展中国家和小国经济的意义。     

Time Inconsistency and the Exchange Rate Channel of Monetary Policy

This paper analyses time–inconsistency problems related to the exchange rate channel of monetary policy. Within a simple open–economy macroeconomic model, where the exchange rate is the only forward–looking variable, we show that a difference emerges between optimal policy under discretion and under commitment. Moreover, the nature of the time–inconsistency problem resembles that resulting from standard New Keynesian models: when cost–push shocks occur, the exchange rate channel gives rise to excessive output stabilisation and insufficient inertia in monetary policy under a discretionary policy.
