Others contend, by contrast, that due to the price inelasticity of supply and demand in commodity markets, speculation could distort commodity prices without any change in inventories. Motivated by this debate, this paper examines the relation between the investment flows into the three main commodity index exchange-traded funds (ETFs) and the prices, inventory and term structure of four US-traded energy commodities. Using weekly inventory data from the Energy Information Agency and futures prices from NYMEX energy contracts, we do not find any significant relation between commodity index flows and inventory or term structure. By contrast, we retrieve the short-term impacts of index flows on energy commodities’ futures prices that have already been evidenced in the literature. An extension of our framework of analysis to twelve US-traded agricultural contracts confirms these conclusions. Hence, our results suggest that stockpiling is not necessarily a “signature” of an abnormal impact of speculators on commodities prices.","PeriodicalId":43528,"journal":{"name":"Journal of Energy Markets","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2018-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46142620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do so, it considers daily data collected between 2008 and 2014. It measures the monetary policy shocks as the change in US ten-year government bond yields immediately after the announcement of relevant events. The findings reveal the crude oil market to be highly reactive to unconventional monetary policy surprises. Surprisingly, when working with shorter windows – that is, of one day right around the announcement of a large-scale asset purchase likely to cause a decrease in long-term interest rates – one documents, in general, a decline in oil price returns and an increase in their associated volatilities, despite the more stimulative financial environment. In contrast, the effects of monetary policy on the oil market one day after any significant announcement are different. As a rule, monetary surprises led to significant increases in oil price. In particular, this paper highlights the ways in which the magnitude of the oil market’s response may be influenced by the size of the study window (that is, the period in which monetary policy may affect prices). This observation raises the question of whether transmission channels drive the relationship between monetary policy and the crude oil market. This paper makes an important contribution to the empirical literature dealing with the link between monetary policy and energy markets: namely, the crude oil futures market and the existing literature focusing on the transmission mechanism. The empirical results entail important implications for industry participants and policy makers alike.","PeriodicalId":43528,"journal":{"name":"Journal of Energy Markets","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2018-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47134962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This calls for additional flexibility in the power market. The right coupling to the underlying national and local district heating (DH) markets can generate large amounts of flexibility. However, regulatory barriers and different energy market designs may hinder the potential benefits from system integration, and lower the potential that can be realized. The Scandinavian countries have a large extension of DH with a good potential for providing flexibility services to the electricity market. We survey and discuss regulatory barriers and drivers for exploiting this potential for flexibility. Combined heat and power (CHP) is widely integrated in the power market, but it is threatened by low electricity prices due to the increasing amounts of wind power. Power-to-heat technologies, electric boilers and heat pumps are blocked by high tariffs and taxes. A calculation of the heat costs of different DH technologies demonstrates that, under the present price and tax conditions in Denmark and Sweden, CHP and power-to-heat are unable to compete with heat-only boilers that use tax-free biomass.","PeriodicalId":43528,"journal":{"name":"Journal of Energy Markets","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2017-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45887071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We formulate a functional optimization problem over a set of regular payoff functions: one is written on energy price, while the other is issued over any index exhibiting statistical correlation to volumetric load. On theoretical grounds, we derive closed-form expressions for both payoff structures under suitable conditions about the statistical properties of the underlying variables; we pursue analytical computations in the context of a lognormal market model and deliver explicit formulas for the optimal derivative instruments. On practical grounds, we first develop a comparative analysis of model output through simulation experiments; next, we perform an empirical study based on data quoted at EPEX SPOT power market. Our results suggest that combined price-volume hedging performance improves along with an increase of the correlation between load and index values. This outcome paves the way for a new class of effective strategies for managing volumetric risk upon extreme temperature waves.","PeriodicalId":43528,"journal":{"name":"Journal of Energy Markets","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2139/ssrn.2689112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68255592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
