Hedging emerging market bonds and the rise of the credit default swap

On October 5, 2001, when credit spreads were widening, the Chicago Mercantile Exchange CME de-listed the full menu of emerging market Brady bond futures contracts. This is intriguing because at a time when interest in hedging and speculating in emerging market sovereign credit risk should be at its peak, the CME de-listed precisely the sort of contract designed to hedge and speculate in sovereign credit risk. This paper finds statistical evidence suggesting that the developing over the counter CDS contract acted as a substitute product for the Brady bond futures contract thereby undermining the Brady bond futures contract and contributing to its demise.     

Activity in futures: does underlying market size relate to futures trading volume?

This study investigates the determinants of trading volume in the futures markets and focuses on underlying market characteristics as an explanation for futures trading volume. Four major futures contracts traded on the Sydney Futures Exchange are investigated: the stock price index (SPI); the 90-day bank accepted bill (BAB); the 3-year bond; and the 10-year bond. An important outcome of this study is an identification of the fundamental drivers of trading volume in the futures markets, which have largely gone undocumented in prior research. We find evidence that futures trading volume is related to underlying market characteristics: the size of the Australian superannuation fund investments in equities (for the SPI), short term treasury notes (for the BAB), non-government bonds on issue (for the 3-year contract) and government bonds on issue (for the 10-year contract).     

Share price volatility with the introduction of individual share futures on the Sydney Futures Exchange

This paper examines a recent innovation in financial derivative securities—individual share futures contracts traded on the Sydney Futures Exchange. We investigate changes in the volatility of the underlying shares in the cash market using an asymmetric exponential ARCH model. The overall evidence suggests that the introduction of futures trading has had very little impact on cash market volatility. Trade in the futures market has less of an effect on cash market volatility than cash market trading for most shares.     

Alternative settlement methods and Australian individual share futures contracts

Individual share futures contracts have been introduced in Australia since 1994. Initially, the contracts were settled in cash. In 1996, cash settlement was gradually replaced by physical delivery. This study investigates the effects of the settlement method change on Australian individual stock and its futures markets. Specifically, we examine whether return and volatility of each market, correlation between the two markets, basis behavior, and hedging performance of futures markets differ across cash settlement period and physical delivery period. We find that, after the switch from cash settlement to physical delivery, the futures market, the spot market, and the basis all become more volatile. However, each individual share futures contract becomes a more effective hedging instrument. The improvement in hedging effectiveness is particularly impressive for the most recently established individual share futures contracts.     

THE RELATION BETWEEN THE FEDERAL FUNDS CASH AND FUTURES MARKETS

The introduction of futures contracts did not alter the regularity in the cash market that results from the Federal Reserve regulation of the bank-settlement process. Although we find a positive preholiday effect in the Fed funds futures returns, we do not find evidence that Federal Reserve regulations cause that effect. Contrary to previous observations for other futures contracts, we find Fridays and preholidays have the largest net volume. We suggest this finding of high volume is consistent with hedging activity by financial institutions before market closings.     

Futures Trading,Spot Price Volatility and Market Efficiency: Evidence from European Real Estate Securities Futures

In 2007 futures contracts were introduced based upon the listed real estate market in Europe. Following their launch they have received increasing attention from property investors, however, few studies have considered the impact their introduction has had. This study considers two key elements. Firstly, a traditional Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model, the approach of Bessembinder & Seguin (1992) and the Gray’s (1996) Markov-switching-GARCH model are used to examine the impact of futures trading on the European real estate securities market. The results show that futures trading did not destabilize the underlying listed market. Importantly, the results also reveal that the introduction of a futures market has improved the speed and quality of information flowing to the spot market. Secondly, we assess the hedging effectiveness of the contracts using two alternative strategies (naïve and Ordinary Least Squares models). The empirical results also show that the contracts are effective hedging instruments, leading to a reduction in risk of 64 %.     

Implicit delivery options and optimal delivery strategies for financial futures contracts

Futures contract specification usually allow the short position some variation as to when, where, how much, and what is to be delivered. In this paper we derive the optimal delivery policy for the Treasury Bond futures contracts, and find that our policy produces profits that are positive and statistically significant. This indicates that future prices are ‘too high’ in that the short position can earn profits by skillfully exercising his delivery options. We find the actual delivery policies of market participants depart substantially from the optimal strategy. The implications of these findings for futures traders and bond dealers are discussed.     

Hedging long-term exposures with multiple short-term futures contracts

This article analyzes the problem facing an agent who has along-term commodity supply commitment and who wishes to hedgethat commitment using short-maturity commodity futures contracts.As time evolves, the agent has to roll the hedge as old futurescontracts mature and new futures contracts are listed. Thisgives rise to hedge errors. The optimal hedging strategy ischaracterized in a world where contracts of several differentmaturities coexist. The strategy is independent both of theagent's risk aversion and, under certain conditions, of beliefsabout expected returns from holding futures contracts. The methodologyis compared with approaches based on dynamic models of the termstructure. It is tested on data from the oil futures market.     

An examination of the relationship between the disposition effect and gender,age, the traded security,and bull–bear market conditions

We analyze how gender and age, internal characteristics of retail futures traders—one that remains fixed while the other changes over a lifetime—and the security being traded and bull–bear market conditions, two external factors, are related to the disposition effect by separately tracking their trade-by-trade transaction histories over a period of close to six years on the Taiwan Futures Exchange (TAIFEX). We show that women and mature traders, compared with their male and younger counterparts, exhibit a stronger disposition effect. The effect is also stronger among traders who trade financial-sector futures contracts than among those who trade electronic-sector futures contracts. We further demonstrate that a bear market sees a stronger disposition effect.

Hedging Corporate Bonds

We examine Treasury bond and stock index futures, the swap curve and two types of hypothetical corporate bond assets as alternative hedging instruments for portfolios of corporate bonds. Conducting ex post and ex ante tests we find evidence that credit quality and maturity are important sources of basis risk when hedging corporate bonds whose credit rating are below triple A. We conclude that a new corporate hedging instrument may be useful for those wishing to hedge corporate bond portfolios provided that transaction costs are not too high relative to existing futures contracts.     

Production flexibility, stochastic separation, hedging, and futures prices

We study a dynamic model where uncertainty about interim outputadjustments causes producers to face price, cost and outputuncertainty. Stochastically separable production decisions areindependent of the producer's risk preferences and expectationsand are based on the prevailing futures price as a certain outputprice. Conditions under which futures contracts achieve stochasticseparation are established. Optimal hedging and maturity structureof futures contracts, equilibrium futures prices, and the effectsof futures trading on output are studied. The systematic riskpremium depends on the product of the futures beta and the covarianceof the market return with production revenues.     

Are They Hedgers or Speculators? Evidence from South Korea's Political Elections

This study uses a simultaneous equation model based on a three-stage least squares estimation to offer new empirical evidence that investors are hedgers or speculators during South Korea's elections. Major investor groups include individuals, securities companies, and foreigners in the Korea Composite Stock Price Index (KOSPI 200) market. The results show that cash market volatility and futures market activity have lead behaviors with one another. However, the contemporaneous variables of cash market volatility and options market activity have only unidirectional causality. Most investors will trade futures and options contracts for speculating within the entire sample period. During political election periods, investors prefer to trade options contracts for hedging rather than futures contracts.     

A MULTIFACTOR MODEL OF THE QUALITY OPTION IN TREASURY FUTURES CONTRACTS

The values of quality options in Treasury futures contracts are set relative to the prices of all coupon bonds in their respective deliverable sets. As a result, any model used to value the quality option should set its price relative to the set of observed bond prices. This requirement rules out the use of most simple equilibrium models that represent all bond prices in terms of a finite number of state variables. We use the two-factor Heath-Jarrow-Morton model, which permits claims to be priced relative to observable bond prices, to investigate the potential value of the quality option in Treasury bond and note futures. We show that the quality option has significantly more value in a two-factor interest rate economy than in a single-factor economy, and that ignoring it could lead to significant mispricing.     

Trading activity and price discovery in Bitcoin futures markets

This study examines the impact of trading activities on price discovery in the Bitcoin futures markets. We find that trades of hedgers are positively correlated with the modified information shares in both CME and CBOE futures markets, suggesting that their trading promotes futures market efficiency. Retailers’ trading activity relates negatively to the price discovery of the CME Bitcoin futures and thus destabilizes the market. Speculators exert positive (negative) impact on the price discovery in the CME (CBOE) Bitcoin futures. Our finding that CME’s Bitcoin futures exhibit superior price discovery than CBOE’s provides plausible justification for CBOE’s decision in March 2019 to suspend further listings of Bitcoin futures contracts.     

Initial margin policy and stochastic volatility in the crude oil futures market

This article examines the relationship between the volatilityof the crude oil futures market and changes in initial marginrequirements. To closely match changes in futures market volatilitywith the corresponding changes in margin requirements, we inferthe volatility of the futures market from the prices of crudeoil futures options contracts. Using a mean-reverting diffusionprocess for volatility, we show that changes in margin policydo not affect subsequent market volatility.     

The Forward Premium in the Nord Pool Power Market

This article investigates the forward premium of futures contracts in the Nordic power market for the time period from January 2004 to December 2013. We find that futures prices are biased predictors of the subsequent spot prices and that there is a significant forward premium in the Nord Pool market, particularly during the winter and autumn. We analyze the impact from several factors on the forward premium. The spot price, and the deviation of water inflow from its usual level, positively affect the forward premium. The variance of the spot price also has a positive effect on the forward premium, but only for the contract closest to delivery.     

The volatility effect of futures trading: Evidence from LSE traded stocks listed as individual equity futures contracts on LIFFE

This study investigates the impact of LIFFE's introduction of individual equity futures contracts on the risk characteristics of the underlying stocks trading on the LSE. We employ the Fama and French three-factor model (TFM) to measure the change in the systematic risk of the underlying stocks which arises subsequent to the introduction of futures contracts. A GJR-GARCH(1,1) specification is used to test whether the futures contract listing affects the permanent and/or the transitory component of the residual variance of returns, and a control sample methodology isolates changes in the risk components that may be caused by factors other than futures contract innovation. The observed increase (decrease) in the impact of current (old) news on the residual variance implies that futures contract listing enhances stock market efficiency. There is no evidence that futures innovation impacts on either the systematic risk or the permanent component of the residual variance of returns.     

Adaptive market efficiency of agricultural commodity futures contracts

In this paper we investigate the adaptive market efficiency of the agricultural commodity futures market, using a sample of eight futures contracts. Using a battery of nonlinear tests, we uncover the nonlinear serial dependence in the returns series. We run the Hinich portmanteau bicorrelation test to uncover the moments in which the nonlinear serial dependence, and therefore adaptive market efficiency, occurs for our sample.     

A Likelihood Ratio Test of Price Volatilities: Comparing Stock Index Spot and Futures

This paper uses three methods to estimate the price volatility of two stock market indexes and their corresponding futures contracts. The classic variance measure of volatility is supplemented with two newer measures, derived from the Garman-Klass and Ball-Torous estimators. A likelihood ratio test is used to compare the classic variance measure of price volatilities of two stock market indexes and their corresponding futures contracts during the bull market of the 1980s. The stock market volatilities of the Standard & Poor's 500 (S&P 500) and New York Stock Exchange (NYSE) indexes were found to be significantly lower than their respective futures price volatilities. Since information may flow faster in the futures markets than in the corresponding stock market, our results support Ross's information-volatility hypothesis. It was also noted that the NYSE spot volatility was lower than the S&P 500 spot volatility. If the rate of information flow and firm size are positively related, then the lower NYSE spot volatility is explained by the size effect. The futures price volatilities for the two indexes were insignificantly different from each other. With stock index spot-futures price correlations approaching unity, one implication of our results for index futures activity is that smaller positions in futures contracts may suffice to achieve hedging or arbitrage goals.
