Asymmetric effects of market uncertainties on agricultural commodities
Energy Economics. 2023. Vol. 127. Article 107080.
The interplay between energy and agricultural commodities and the responses of agricultural commodities to global uncertainty factors have been receiving increasing attention due to the pivotal contributions of commodity markets to the world economy. This study investigates the asymmetric effects of oil, market volatility and sentiment, economic policy uncertainty, and geopolitical risk on agricultural commodities in a nonparametric quantile-on-quantile regression framework. The sample used for empirical analysis spans January 03, 2013, to October 21, 2022, and includes ten agricultural commodities (canola, cocoa, coffee, corn, feeder cattle, lean hogs, live cattle, orange juice, sugar, and wheat), crude oil, crude oil implied volatility (OVX), market sentiment (VIX), economic policy uncertainty of the US (USEPU), and geopolitical risk (GPR). The empirical findings suggest that crude oil fails to serve as either a hedge or safe-haven for agricultural commodities. Meanwhile, OVX and VIX serve as potential hedges against agricultural commodity shocks. At elevated levels of USEPU, agricultural commodities reveal only weak hedging capacities against the USEPU-driven downside risks and mostly act just as diversifiers of economic policy uncertainty effects. However, they could hedge against the crystallisations of the downside geopolitical risks. These findings are important for effective regulation policies, risk management, and portfolio decisions across bullish, bearish, and normal market conditions.

This study empirically tests the deposit channel hypothesis, which holds that increases in deposit markups cause liquidity outflows from the banking sector and a contraction in credit supply. The central question is whether deposit substitution effects, whereby depositors shift funds to other financial instruments during monetary tightening, are reflected in banks’ balance sheets and aggregate ...

Russia is an interesting case: a relatively young consumer-finance market in which a lack of financial literacy may increase the likelihood of household over-indebtedness. To test this hypothesis, ...

The paper analyses the dynamic connectedness between trading volumes in the Russian stock market and the global cryptocurrency (Bitcoin) market during periods of external shocks (the COVID‑19 crisis and the Russia‑Ukraine conflict) from 2019. Using the TVP‑VAR model and estimates of system variable connectivity, liquidity spillovers (cash flows) are identified between the considered asset classes. For the first time, we analyse the network connectedness of investor sentiment for the most popular Russian stocks and Bitcoin and estimate the role of sentiment in liquidity spillovers. The results demonstrate that Bitcoin’s daily trading volume predominantly acts as a recipient of shocks from the Russian stock market. Meanwhile, the overall coherence in the system was higher during the COVID‑19 crisis period compared to the Special Military Operation (SMO). The study confirms the existence of a correlation between investor sentiment on the Russian stock and cryptocurrency markets. At the beginning of the analyzed period,in 2019, when interest in crypto assets investing began to grow rapidly, this correlation was strongly pronounced.
There is a connectedness between two sentiment indices: on the stock market and crypto‑assets. The intensity of the correlation prevails in the COVID‑19 inception period, significantly exceeding the level observed in the SMO period. This sentiment metrics behaviour may imply adaptation of the Russian stock market to external shocks, as well as retail investors’ expectations of short‑term SMO in early 2022. ...
