Macroeconomic and aggregate financial series were shown empirically to share an unconventional form of cyclical and persistent dynamics, whose functional form was obtained from the solution of general-equilibrium models with heterogeneous firms. The econometric modeling of equations that link such series requires a new methodology, as existing parametric techniques can cause paradoxical regression results and omit predictabilities. We provide a solution to disentangle the genuine relation between variables (the parameters linking them) from the unconventional dynamics that drive them. As an application, we show that GBP-USD forward premia have no predictive power for excess returns over 1976–2015 (thus solving this forward-premium puzzle) once the unconventional dynamics of spot rates are modeled. Taking advantage of these dynamics, we uncover a trading strategy which consistently outperforms existing ones in the out-of-sample period 2015–2021, delivering almost treble their profits and yielding a Sharpe ratio of 85%. Hence, even in this heavily traded market, the efficient market hypothesis has been failing for over 45 years as persistent profit opportunities remained unexploited because of the unconventional dynamics of the spot rate.

We study two sources of heteroscedasticity in high-frequency financial data and estimate their contribution to overall volatility by means of a Markov switching (MS) structural VAR model. We achieve identification for all coefficients by assuming that the structural errors follow a GARCH-DCC process. Using transaction data of the EUR/USD interdealer market in 2016, we first detect three regimesof volatility. Then we show that both sources of volatility matter for the transmission of shocks, and that information is channeled to the market mostly through demand shocks. This suggests that, on the EUR/USD market, some liquidity takers (LTs) are better informed than both liquidity providers and those LTs who follow a feedback strategy. [ABSTRACT FROM AUTHOR]

The fiscal policy's impact on the real exchange rates is highly controversial in theory and practice but noteworthy for macroeconomic policy. This issue is more pertinent in developing countries with an active fiscal policy or wider fiscal space but is explored less. To our knowledge, the fiscal policy impact on the real exchange rate in India is not documented. Against this backdrop, this study explores this in India involving disaggregated data of government consumption and investment spending and a few related variables like trade openness, private consumption spending, and money supply for the period 1996:1–2023:1. The results corroborate long-run associations of real exchange rate and some combinations of the selected other variables. The real exchange rate dynamics estimated through the cointegrated vector autoregressive model followed by an impulse response analysis have shown that government investment spending causes a real appreciation. In contrast, government and private consumption spending exert pressure to depreciate the real exchange rate. Trade openness is another potent predictor of the real exchange rate. On the other hand, no significant impact of the money supply on the real exchange rate is noticed. The results accentuate effective fiscal allocation may be a policy tool for stabilizing the Indian rupee. The unique findings on the Indian economy may also help understand the fiscal effect of real exchange rates in other developing countries. [ABSTRACT FROM AUTHOR]

This study offers unique insights into the threshold-based influence of currency devaluation (CD) on external debt sustainability (EDS) in designated Sub-Saharan African (SSA) countries. The absence of evidence from this viewpoint, particularly in SSA, inspires this new assessment. On this premise, the study utilizes two innovative estimation procedures: smooth transition regression (STR) and multiple thresholds nonlinear ARDL (MTNARDL) to estimate the sign-based and magnitude-based asymmetric influence of CD on EDS. The outcomes indicate that first, an average CD threshold of 21.1% is consistent with EDS in the designated nations; second, a small CD significantly reduces the external debt–GDP ratio and improves sustainability, while a very high CD largely worsens the EDS problem; third, in the CD regime, devaluation has more detrimental effects on external debt burden; fourth, exceedingly large changes in exchange rate (whether positive or negative) essentially affect the countries’ EDS negatively; and fifth, the adverse effect of large depreciation on EDS is greater than that of large appreciation. The study recommends, amongst others, that heavily indebted countries with sizeable external debt denominated in foreign currency should, as a matter of urgency, avoid excessive and escalated large percentages of devaluation or exchange rate depreciation.

This study analyzes the effect of monetary policy, which are proxied by weighted average cost of funding (WACF) and Borsa Istanbul repurchase interest rate (REPO), on the returns of the main financial assets of monetary policy in Türkiye. Using daily data between January 4, 2011 and August 31, 2023, the study applies novel nonlinear time-series methods, such as wavelet coherence (WC) and quantile-on-quantile regression (QQ) as baseline methods and quantile regression (QR) for robustness. The findings demonstrate that (i) monetary policy has a stronger effect on financial asset returns at middle and higher frequencies across different periods; (ii) monetary policy has mainly declines (increases) effect on financial asset returns at lower and middle (higher) quantiles; (iii) the robustness of the outcomes is confirmed. Thus, the outcomes show that monetary policy has a significant effect on financial asset returns, and the effects vary across times, across frequencies, quantiles, and financial assets.

The foreign reserves sufficiency is important to maintain macroeconomic stability. The main objective of this paper is to model the behaviour of the central bank in accumulating the foreign reserves in the case of Indonesia. Unlike the previous empirical studies, this paper disaggregates the components of foreign reserves into foreign currency, securities, gold, and special drawing rights. This paper relies on the Almost Ideal Demand System combined with the Error Correction Model. The estimation result for monthly data over the period 2010(1)-2020(12) reveals that the own-price coefficients are negative and statistically significant which is consistent with the standard theory of demand. While the foreign currency-securities pairwise is substitutive, the foreign currency-gold and the foreign currency-special drawing rights pairwise are complementary or even independent. However, the wealth effect is inelastic except for securities reserves. These results imply that the central bank of Indonesia can re-balance its reserves. The securities holding which have the highest proportion of foreign reserve scan be switched to foreign currency, gold, and/or special drawing rights. The rebalancing measures would remain having an optimal level of foreign reserves holding in terms of its opportunity cost. Therefore, the monetary authority can conduct a further macroeconomic stabilisation without substantially losing the returns.

We employ a threshold vector error correction model approach to investigate the impact of China's exchange rate marketization reform in August 2015 on the linkage between renminbi (RMB) onshore (CNY) and offshore (CNH) exchange rates and the impact of post-reform policy interventions by the People's Bank of China (PBoC) on CNY–CNH linkage. We find that, after the reform, price power over the RMB exchange rate changed from the onshore to the offshore market, in which the CNH significantly leads the CNY, and the CNY ceased to lead the CNH. Since the reform, the PBoC has faced a trilemma of exchange rate marketization, RMB internationalization, and maintenance of the onshore market's pricing power over the RMB exchange rate. The PBoC regained its RMB pricing power by reinforcing control over the onshore exchange rate and tightening offshore RMB liquidity, at the expense of setbacks in both exchange rate marketization and RMB internationalization.

Purpose: This article examines if the national productions of West African Economic and Monetary Union (WAEMU) countries can be substituted for the imports by testing MLRC in these countries. Design/methodology/approach: The Mundell–Fleming model (MMF) is the analytical framework adopted in this paper with import demand and export supply functions estimation borrowed to Thirlwall (1979). This study covers four countries in West Africa from 1990 to 2021. The estimation procedure used is an Autoregressive Distributed Lag (ARDL) approach to cointegration. Findings: The findings reveal that there is a strong marginal propensity to import in the WAEMU countries. The hypothesis of a non-significant price effect on imports in the short-term is confirmed for several countries while only Togo satisfies the MLRC in the short and long run. Originality/value: This study presents several originalities: (1) it evaluates MLRC with a clear analytical framework; (2) unlike other studies, this article quantifies the MLRC from a theoretical, econometric and empirical point of view; (3) this article presents the results country by country in order to reveal heterogeneity between countries; (4) this study adds to the Marshall–Lerner condition for the derivation of Robinson by considering a situation where initially the trade balance is not in equilibrium.

Research background: The aim of this paper is to examine the long run relationship among oil prices and the Algerian Dinar exchange rate over the period January 1995–February 2020 in Algeria as one of the most important oil-exporting countries and one of the OPEC members.

The question of whether domestic prices respond to either official exchange rate or parallel exchange rate movement is a key research issue especially in an oil-dependent developing country like Nigeria with rising fiscal pressures and a vibrant parallel market. Also from the monetary authority perspective, it is imperative to know if prices respond symmetrically and/or asymmetrically to both official and parallel exchange rates movement. Consequently, this study examines the response of domestic prices to both official and parallel exchange rates movement for the period 1995Q1-2019Q1 with the Shin et al. (In: Horrace WC, Sickles RC (eds) Festchrift in Honour of Peter Schmidt. Springer, New York, pp 281–414, 2014) nonlinear ARDL approach. The results provide support for prices responding symmetrically to parallel rates than the official rate especially in periods of large exchange rate premium. However, prices only respond differently to depreciation and appreciation of the official exchange rate in Nigeria. Consequently, the government needs to ensure some levels of fiscal austerity and possible exchange rate unification when the premium gets large if the intention is to insulate domestic prices from fiscal pressures. Also, the Central Bank of Nigeria needs to take cognizance of possible asymmetric relationship in their decisions to ensure price stability so as not to distort monetary policy effect.

Purpose – The purpose of this paper is to examine and analyze the exchange rate pass-through into inflation (ERPT) in Vietnam. Design/methodology/approach – The paper examines and analyzes the ERPT in Vietnam by applying vector autoregression model over the period 2008‒2018. Findings – The key finding of the research is that from the impulse response results, the transmission of exchange rate shocks to inflation is significant in Vietnam, and this is incomplete exchange rate pass-through. Moreover, the evidence from variance decompositions argues that exchange rate is an important factor to explain the fluctuation of inflation. Originality/value – In overall, the depreciation or appreciation of exchange rate in Vietnam will considerably impact inflation.

Purpose – The purpose of this paper is to evaluate and analyze impacts of the monetary policy (MP) – money aggregate and interest rate – on the exchange rate in Vietnam. Design/methodology/approach – The study uses data over the period of 2008–2018 and applies the vector autoregression model, namely recursive restriction and sign restriction approaches. Findings – The main empirical findings are as follows: a contraction of the money aggregate significantly leads to the real effective exchange rate (REER) depreciating and then appreciating; a tightening of the interest rate immediately causes the REER appreciating and then depreciating; and both the money aggregate and the interest rate strongly determine fluctuations of the REER. Originality/value – The quantitative results imply that the MP affects the REER considerably.

Background: Cryptocurrencies represent a specific technological innovation in financial markets that keeps getting more and more popular among investors around the world. Given the specific characteristics of the cryptocurrencies, this paper examines the possibility of their use as a diversification instrument.

Central banks seek to guide the foreign exchange market through interventions. However, the success of the central bank in guiding the forex markets, much like the biblical Moses, depends on the differing perceptions and resulting bid–ask spreads of market participants following intervention. Using high-frequency data, we study the behaviour of exchange rate volatility (as reflected in change in bid–ask spreads) following intervention by Reserve Bank of India, India's central bank. We find that intervention increases the probability of volatility being in higher ranges. Event-wise analysis shows an increase in volatility in shorter time frames and a decrease in volatility over the longer time frame of the day, following intervention. [ABSTRACT FROM AUTHOR]

This paper sheds light on global GDP spillovers in the context of external imbalances. We adopt a Bayesian time-varying panel vector autoregression framework to analyze the global implications of changes in assets and liabilities of the US and the Euro Area in a global framework which includes 25 industrial and emerging economies. We find significant evidence for assets and liabilities spillovers from positions in the Euro Area and the US which often result in negative effects on GDP growth. [ABSTRACT FROM AUTHOR]
