There is clear evidence from many previous studies that UIP does not hold with monthly data. However, a recent study by Baillie, Diebold, Kapetanios, Kim and Mora (2025) advocated the “Durbin" regression approach to modeling time series regressions. This paper extends the application of that approach and finds strong evidence that information contained in lagged spot and forward exchange rates indicates that UIP is valid over long horizons. This evidence is based on heavily traded 30 day forward markets and avoids dealing with long term bonds and HAC robust standard errors. The evidence is important in confirming the validity of the long-run international Fisher condition, which is a vital cornerstone of international finance.
许多先前的研究都有明确的证据表明,UIP并不适用于月度数据。然而,Baillie, Diebold, Kapetanios, Kim和Mora(2025)最近的一项研究主张使用“Durbin”回归方法来建模时间序列回归。本文扩展了该方法的应用,并发现了强有力的证据,即滞后的现货和远期汇率中包含的信息表明,UIP在长期范围内是有效的。这一证据是基于交易量很大的30天远期市场,并避免了处理长期债券和HAC稳健的标准误差。这些证据对于确认长期国际费雪条件的有效性具有重要意义,而费雪条件是国际金融的重要基石。

This paper examines monthly returns from over 48,120 stocks across 36 countries/regions, employing an iterative two-step LASSO methodology to identify key factors in global markets. The result is a novel global factor model that incorporates factors such as market dynamics, profit growth, quality, momentum, investment, size, and debt issuance. This model outperforms existing approaches by providing a superior explanation of global asset pricing anomalies and achieving lower average pricing errors. A distinguishing feature of our model is its efficacy in explicating anomalies in local markets, diverging from traditional models that typically confine their scope to local market dynamics. Overall, this research highlights the potential of machine learning-based frameworks in developing a more comprehensive and robust global factor model for international asset pricing.
本文研究了36个国家/地区超过48120只股票的月回报,采用迭代的两步LASSO方法来确定全球市场的关键因素。其结果是一个新的全球因素模型,该模型结合了市场动态、利润增长、质量、势头、投资、规模和债务发行等因素。该模型优于现有的方法,提供了对全球资产定价异常的更好解释,并实现了更低的平均定价误差。我们的模型的一个显著特征是它在解释当地市场异常方面的有效性,与传统模型不同,传统模型通常将其范围局限于当地市场动态。总的来说,这项研究强调了基于机器学习的框架在为国际资产定价开发更全面、更稳健的全球因素模型方面的潜力。

The path to currency internationalization: Insights from the Chinese renminbi 货币国际化之路:来自中国人民币的洞察
IF 3.3 2区 经济学 Q2 BUSINESS, FINANCE Pub Date : 2026-01-01 Epub Date: 2025-10-25 DOI: 10.1016/j.jimonfin.2025.103449

What matters for a currency to gain an international status? To explore this question, we examine the evolving role of the Chinese renminbi (RMB) in trade invoicing over 2003–2021 and the factors contributing to its heterogeneity using detailed trade data for Korea, China’s largest trading partner. China’s policy reform in 2009, permitting cross-border RMB settlement, boosted RMB invoicing in Korean exports particularly to China, but the US dollar’s existing dominance in trade with China impeded the expansion of RMB. Our study also finds that opening a direct FX market for RMB in 2014 further stimulated RMB usage in exports to non-Chinese destinations. This effect was more pronounced in destination countries with close trade ties or currency swap lines with China, and in exporting industries using more RMB-denominated inputs. These findings highlight the complementarity between a country’s economic fundamentals and government policies in internationalizing its currency.
一种货币获得国际地位的关键是什么?为了探讨这个问题,我们使用中国最大的贸易伙伴韩国的详细贸易数据,研究了2003-2021年人民币在贸易发票中的演变作用,以及导致其异质性的因素。我们的研究还发现,2014年人民币直接外汇市场的开放进一步刺激了人民币对非中国目的地出口的使用。在与中国有密切贸易关系或货币互换额度的目的地国,以及使用更多人民币计价投入的出口行业,这种影响更为明显。这些发现突出了一个国家的经济基本面和政府在货币国际化方面的政策之间的互补性。

The lasting effect of yen-buying interventions: Two cases of Japanese FX interventions in 1997–98 and 2022 日元购买干预的持续影响:1997-98年和2022年日本外汇干预的两个案例
IF 3.3 2区 经济学 Q2 BUSINESS, FINANCE Pub Date : 2026-01-01 Epub Date: 2025-10-17 DOI: 10.1016/j.jimonfin.2025.103445

This paper uses a synthetic control method (SCM) to estimate the lasting effect of yen-buying and dollar-selling interventions in two cases of Japanese foreign exchange (FX) interventions in 1997–98 and 2022. Our analysis using this method enables us to estimate the causal impact of FX intervention on yen-dollar rate for each intervention event by constructing the counterfactual for change in the yen-dollar rate as the optimal weighted average of changes in several hundred exchange rates that were not directly affected by Japanese intervention through a data-driven approach. In the recent case of Japanese interventions in 2022, we find that while the effect of the yen-buying intervention on September 22 was short-lived, the effect in the event of October 21 and 24 lasted for more than 10 business days after the intervention. In the case of yen-buying interventions during the Japanese financial crisis in 1997–98, while the effects of the single interventions in the events of December 17–19, 1997, and April 9 and 10, 1998, were short-lived, the effect of the coordinated intervention by the monetary authorities of Japan and the US on June 17, 1998, lasted more than 10 business days after the intervention. These findings are robust to employing a Ridge Augmented SCM and a synthetic difference-in-differences.
本文采用综合控制方法(SCM)对1997-98年和2022年日本外汇干预的两种情况下,日元买入和美元卖出干预的持续效果进行了估计。我们使用这种方法的分析使我们能够通过数据驱动的方法构建日元兑美元汇率变化的反事实,作为几百种不受日本干预直接影响的汇率变化的最优加权平均值,从而估计外汇干预对每次干预事件的日元兑美元汇率的因果影响。在最近的2022年日本干预的案例中,我们发现,虽然9月22日的日元购买干预的影响是短暂的,但10月21日和24日的影响在干预后持续了10多个工作日。以1997 - 98年日本金融危机期间的日元购买干预为例,1997年12月17 - 19日和1998年4月9日和10日事件中单一干预的效果是短暂的,而1998年6月17日日本和美国货币当局协调干预的效果在干预后持续了10多个工作日。这些发现对于采用Ridge增强SCM和合成差中差是稳健的。

Forecasting stock return: The role of idiosyncratic asymmetry risk 股票收益预测:特质不对称风险的作用
IF 3.3 2区 经济学 Q2 BUSINESS, FINANCE Pub Date : 2026-01-01 Epub Date: 2025-10-30 DOI: 10.1016/j.jimonfin.2025.103464

This paper introduces a novel methodology for quantifying return asymmetry. Our investigation yields two principal findings. First, through nonparametric testing, we establish that our proposed measure demonstrates enhanced testing efficiency relative to conventional third-order skewness. Second, our analysis reveals that the proposed asymmetry metric serves as a robust predictor of cross-sectional equity returns. Consistent with theoretical predictions in the extant literature, we document a negative relationship between return asymmetry and subsequent stock performance. Our empirical evidence suggests that the cross-sectional pricing power of the asymmetric measure can be partially attributed to mispricing and arbitrage constraints. Moreover, we find that the asymmetric risk premium in the Chinese stock market is approximately twice the magnitude observed in the U.S. market.
本文介绍了一种量化收益不对称的新方法。我们的调查有两个主要发现。首先,通过非参数检验,我们确定了我们提出的测量相对于传统的三阶偏度具有更高的测试效率。其次,我们的分析表明,所提出的不对称指标是横截面股权回报的稳健预测指标。与现有文献的理论预测一致,我们记录了回报不对称与随后的股票表现之间的负相关关系。我们的经验证据表明,不对称措施的横截面定价权可以部分归因于错误定价和套利约束。此外,我们发现中国股市的不对称风险溢价大约是美国市场的两倍。

Riding the rate wave: Interest rate and run risks in euro area banks during the 2022–2023 monetary cycle 乘着利率浪潮:2022-2023年货币周期期间欧元区银行的利率和运行风险
IF 3.3 2区 经济学 Q2 BUSINESS, FINANCE Pub Date : 2026-01-01 Epub Date: 2025-10-22 DOI: 10.1016/j.jimonfin.2025.103444

This paper examines how the ECB’s 2022–2023 interest rate hikes affected euro area banks’ economic net worth and vulnerability to deposit runs. Drawing on granular, confidential data for 139 banks, we estimate each bank’s economic net worth and find that unrealised losses on loans and bonds averaged around 30 % of equity. By September 2023, roughly half of these losses had been offset by gains from the deposit franchise and interest rate swaps. We develop a theoretical framework linking banks’ economic net worth and deposit rate setting to depositor behaviour and run incentives. We demonstrate that banks with larger unrealised losses raised their deposit rates by less–a pattern we interpret as banks leveraging a more valuable deposit franchise to fund longer–duration assets. Although euro area banks as a whole avoided widespread runs, several institutions nonetheless carried substantial mark–to–market losses, suggesting latent fragilities.
本文研究了欧洲央行2022-2023年加息对欧元区银行经济净值和存款挤兑脆弱性的影响。根据139家银行的详细机密数据,我们估计了每家银行的经济净值,发现贷款和债券的未实现损失平均约为股本的30%。到2023年9月,这些损失中约有一半被存款特许经营权和利率掉期的收益所抵消。我们开发了一个理论框架,将银行的经济净值和存款利率设定与存款人行为和运行激励联系起来。我们证明,未实现亏损较大的银行提高存款利率的幅度较小——我们将这种模式解释为银行利用更有价值的存款特许经营权来为长期资产提供资金。尽管欧元区银行整体上避免了大规模挤兑,但仍有几家机构蒙受了大量按市值计价的损失,这表明它们存在潜在的脆弱性。

Impermanent loss in cryptocurrency 加密货币的暂时损失
IF 3.3 2区 经济学 Q2 BUSINESS, FINANCE Pub Date : 2026-01-01 Epub Date: 2025-11-19 DOI: 10.1016/j.jimonfin.2025.103476

Impermanent loss risk is a unique risk related to liquidity provision to cryptocurrency exchange pools in Decentralized Finance (DeFi) protocols. To better understand the characteristics of this emergent risk, we first identify the determinants of impermanent loss risk across 1,715 liquidity pools traded on the two largest exchanges. We then explore how impermanent loss is priced in the cross-section of cryptocurrency liquidity pool expected returns. Through a series of portfolio analyses, we document a significantly positive cross-sectional relationship between impermanent loss risk and expected returns. Drawing on a liquidity-based hypothesis, we further demonstrate how the presence of impermanent loss risk impedes liquidity provision and accelerates liquidity demand. Collectively, our results provide strong evidence supporting the important role of impermanent loss risk in determining cryptocurrency liquidity pool returns.
非永久性损失风险是与去中心化金融(DeFi)协议中加密货币交换池的流动性提供相关的一种独特风险。为了更好地理解这种紧急风险的特征,我们首先确定了在两个最大的交易所交易的1,715个流动性池中的非永久性损失风险的决定因素。然后,我们探讨了短期损失是如何在加密货币流动性池预期回报的横截面中定价的。通过一系列的投资组合分析,我们证明了非永久性损失风险与预期收益之间的显著正截面关系。利用基于流动性的假设,我们进一步证明了非永久性损失风险的存在如何阻碍流动性提供并加速流动性需求。总的来说,我们的研究结果提供了强有力的证据,支持无常损失风险在决定加密货币流动性池回报方面的重要作用。

We examine the risks and rewards of investing by constructing a comprehensive market portfolio valued at $150 trillion in global assets and spanning 1970–2022 at a monthly frequency. The monthly frequency allows for a more accurate estimate of investment risks compared to previous studies. Although the Sharpe ratio of the global market portfolio is not much higher than that of equities, it is much more stable over time. In addition, the drawdowns of the global market portfolio are less deep and shorter. When the market portfolio is expressed in currencies other than the U.S. dollar, risks of investing appear larger.
我们通过构建一个价值150万亿美元的全球资产的综合市场投资组合,以每月的频率检查投资的风险和回报。与以前的研究相比,每月的频率可以更准确地估计投资风险。尽管全球市场投资组合的夏普比率并不比股票高多少,但随着时间的推移,它要稳定得多。此外,全球市场投资组合的下跌幅度较小,时间也较短。当市场投资组合以美元以外的货币表示时,投资风险似乎更大。

This study employs the Tail-Event driven NETwork (TENET) method to construct contagion networks of exchange rate tail risks among 40 major global currencies over the period 2010–2023. Based on these networks, we develop indicators to measure systemic risk and analyze their dynamic evolution. The results reveal that, during periods of extreme events, the contagion level among major currencies escalates markedly, demonstrating cyclic patterns. Moreover, compared with emerging economies, developed economies tend to exhibit a higher level of exchange rate tail-risk emission but a lower level of risk reception, with a discernible synchronization between risk reception and emission. This study further investigates how exchange rate tail-risk contagion influences international trade. The analysis shows that such contagion adversely affects both imports and exports, with a more pronounced impact on imports. The reduction in trade volume due to exchange rate tail risk is mainly observed between developed and emerging economies, as well as between member and non-member countries of specific economic cooperation organizations. These results provide empirical evidence of the trade-related consequences of exchange rate tail-risk contagion and highlight the importance of mitigating such contagion and enhancing financial resilience in international trade.
本研究采用尾事件驱动网络(TENET)方法构建了2010-2023年期间全球40种主要货币汇率尾部风险的传染网络。基于这些网络,我们建立了衡量系统性风险的指标,并分析了它们的动态演变。结果表明,在极端事件期间,主要货币之间的传染水平显着上升,表现出周期性模式。此外,与新兴经济体相比,发达经济体往往表现出较高的汇率尾部风险排放水平,而较低的风险接受水平,风险接受与风险排放之间存在明显的同步性。本研究进一步探讨汇率尾部风险传染如何影响国际贸易。分析表明,这种传染对进口和出口都有不利影响,对进口的影响更为明显。汇率尾部风险导致的贸易量减少主要表现在发达经济体与新兴经济体之间,以及特定经济合作组织成员国与非成员国之间。这些结果为汇率尾部风险传染的贸易相关后果提供了经验证据,并强调了减轻这种传染和增强国际贸易金融弹性的重要性。
