Crowding Out in a Dual Currency Regime? Digital Versus Fiat Currency

In this article, we analyze a dual currency regime with fiat currency and digital currency and investigate potential crowding-out effects of fiat currency or digital currency under the framework of the traditional monetary economic model. We find that crowding out occurs only under extreme assumptions, i.e., extremely high costs associated with the use (medium of exchange and store of value) of one currency and extremely low costs associated with the use of the other currency.     

The economics of Bitcoin and similar private digital currencies

Recent innovations have made it feasible to transfer private digital currency without the intervention of an organization such as a bank. Any currency must prevent users from spending their balances more than once, which is easier said than done with purely digital currencies. Current digital currencies such as Bitcoin use peer-to-peer networks and open source software to stop double spending and create finality of transactions. This paper explains how the use of these technologies and limitation of the quantity produced can create an equilibrium in which a digital currency has a positive value. This paper also summarizes the rise of 24/7 trading on computerized markets in Bitcoin in which there are no brokers or other agents. The average monthly volatility of returns on Bitcoin is higher than for gold or a set of foreign currencies in dollars, but the lowest monthly volatilities for Bitcoin are less than the highest monthly volatilities for gold and the foreign currencies.     

把握历史机遇 承担做市使命

国际金融危机以来,央行抓住历史机遇适时启动人民币国际化进程,推出跨境贸易人民币结算试点及新兴市场货币挂牌工作。在央行指引下,中国银行全行统一部署,充分发挥各项优势,两项业务均取得可喜成果。同时,中国银行俄罗斯子行在莫斯科银行间货币交易所也应邀成为卢布兑人民币市场的做市商,实现了国内海外的同时做市。未来中国银行将一如既往地积极参与人民币国际化进程,脚踏实地地推动新兴市场货币做市业务发展,承担历史赋予的使命。     

推进新疆跨境贸易人民币结算的设想

2010年6月,新疆被确定为跨境贸易人民币结算试点区域,霍尔果斯口岸跨境人民币结算取得突破性进展。新疆边境口岸地区跨境人民币结算的制约因素是：双边本币结算仍不活跃、依靠汇率套算、市场需求测定难、政策发挥实效难、制度安排上存在矛盾、跨境划转基础条件不完备等。本文设想了新疆边境口岸地区推进跨境人民币结算试点的路径：选择哈萨克斯坦为重点推进国、增加新疆地区境外人民币存量、探索建立边贸本币汇率协调机制、准确定位人民币跨境贸易结算试点目标交易主体和客体范围。     

An Assessment of the Currency Board Regime in Bosnia and Herzegovina

This paper describes currency board regime operations in Bosnia and Herzegovina and assesses their performance and sustainability in the context of the economic, political, and institutional environment. To the best of our knowledge, our study seems to be unique in this respect. Based on our analysis, we judge that Bosnia and Herzegovina's currency board regime is well suited and appropriate, given the country's history, its current state, and its future goals. Nevertheless, we believe that the key to the currency board's sustainability, and an eventual accession to the European Union, is a stronger legal and regulatory infrastructure and a more unified political system.     

Financial dollarization in Russia: causes and consequences

We review some aspects of financial dollarization in Russia, applying the main relevant theories to analyse the dynamics of several dollarization indicators. An econometric model of the short-run dynamics of deposit and loan dollarization is estimated for the last decade. We find that ruble appreciation was the main driver of the de-dollarization that occurred then and of the later episode of renewed dollarization. We estimate the overall (and sectoral) currency mismatches of the Russian economy. Evidence is presented for the significant currency risk vulnerability of the non-banking private sector.     

美元加息对新兴市场国家的影响与对策

2018年4月以来,美元持续多次加息,多个新兴市场国家本币大幅贬值、股市急剧下跌、债市承压动荡,资本外流压力进一步显现。新兴市场国家金融动荡的导火索以外部因素为主,风险传播渠道以跨境联动因素为主,风险放大渠道以内部因素为主。在美元加息背景下,新兴市场国家要妥善处理自身货币与美元之间的关系,避免过于依赖美元,过多承担短期美元债务。支持法国、德国等提出的建立新独立国际支付体系的倡议,避免部分国家将国际公共的金融基础设施作为制裁手段。     

International Equity Index and Currency Futures: Commodity Currencies or Emerging Versus Developed Markets?

Equity index futures in both emerging and developing markets that are net commodity exporters are strongly linked to their respective currency futures markets. Unconditional correlations among equity and currency futures are the highest for these net basic materials producers in both emerging and developed markets. Granger causality tests also indicate that stock market returns are more strongly related to currency futures returns for commodity-exporting countries. Additionally, conditional correlations among currency and equity futures returns are the strongest for commodity-producing countries in both emerging and developed economies. Volatility spillover analysis provides consistent results. The overall results indicate that the status of a country as a net importer or exporter of raw materials is more important to the relationship between equity and currency futures than whether it is an emerging or developed economy.     

Capture the contagion network of bitcoin – Evidence from pre and mid COVID-19

COVID-19 is the first global scale crisis since the inception of Bitcoin. We compare the contagion phenomenon of Bitcoin and other financial markets or assets pre and during the COVID-19 shock in both contemporaneous and non-contemporaneous manner. This paper uses the directed acyclic graph (DAG), spillover index, and network topology to provide strong evidence on the directional contagion outcomes of Bitcoin and other assets. The empirical results show that the contagion effect between Bitcoin and developed markets is strengthened during the COVID-19 crisis. Particularly, European market has a dominant role. Excluding Bitcoin’s own shocks, United State and European markets are the main contagion sources to Bitcoin. European market also works as a intermediary to deliver infectious from United State and market fear. The findings show that gold always has contagion effect with Bitcoin, while gold, US dollar and bond market are the contagion receivers of Bitcoin under the shock of COVID-19. The empirical results further proved the safe haven, hedge and diversifier potential of Bitcoin in economic stable time, but also shows that the sustainability of these properties is undermined during the market turmoil.     

Does bitcoin co-move and share risk with Sukuk and world and regional Islamic stock markets? Evidence using a time-frequency approach

This paper examines the co-movements between Bitcoin (BTC) and the Dow Jones World Stock Market Index, regional Islamic stock markets, and Sukuk markets. We apply cross wavelet transform and wavelet coherence analysis with a wavelet-based measure of value at risk. The co-movement is stronger and in the same direction at lower frequencies, suggesting the benefits from diversification with BTC are relatively less for long-term investors compared to short-term investors. Co-movement in the opposite direction at high frequencies implies better benefits of hedging in the short run through diversification in BTC and Islamic equity markets. Robustness tests show that the correlations increase as we increase from an investment horizon of two days to one of 64 days. The frequency-domain causality test shows significant causality flow from BTC to the Islamic market of Asia-Pacific, Japan, and Sukuk markets in the short term. Additionally, BTC is found to lead Asia-Pacific Islamic stock markets in the long term. Finally, we note that the benefits of portfolio diversification with BTC and Islamic assets vary across time and frequencies.     

Heterogeneity of Funds and Information Disclosure: Evidence

Institutional investors, especially public funds, play an important role in governing listed firms as they grow in Chinese stock markets. We classify each fund as “dedicated,” “transient,” or “mixed,” according to the concentration, turnover, and profit sensitivity of their stock holdings. We find that listed firms with more shares held by dedicated funds have a higher disclosure quality, while firms with more shares held by transient funds have a lower disclosure quality. These findings are consistent in different model settings. In addition, dedicated funds improve the disclosure quality of non-state-owned enterprises more than state-owned enterprises. Dedicated funds can benefit from the lower debt-financing cost and higher stock liquidity of firms with better disclosure quality.
