  • Section 1256 and Foreign Currency Derivatives
    Section 1256 and Foreign Currency Derivatives Viva Hammer1 Mark-to-market taxation was considered “a fundamental departure from the concept of income realization in the U.S. tax law”2 when it was introduced in 1981. Congress was only game to propose the concept because of rampant “straddle” shelters that were undermining the U.S. tax system and commodities derivatives markets. Early in tax history, the Supreme Court articulated the realization principle as a Constitutional limitation on Congress’ taxing power. But in 1981, lawmakers makers felt confident imposing mark-to-market on exchange traded futures contracts because of the exchanges’ system of variation margin. However, when in 1982 non-exchange foreign currency traders asked to come within the ambit of mark-to-market taxation, Congress acceded to their demands even though this market had no equivalent to variation margin. This opportunistic rather than policy-driven history has spawned a great debate amongst tax practitioners as to the scope of the mark-to-market rule governing foreign currency contracts. Several recent cases have added fuel to the debate. The Straddle Shelters of the 1970s Straddle shelters were developed to exploit several structural flaws in the U.S. tax system: (1) the vast gulf between ordinary income tax rate (maximum 70%) and long term capital gain rate (28%), (2) the arbitrary distinction between capital gain and ordinary income, making it relatively easy to convert one to the other, and (3) the non- economic tax treatment of derivative contracts. Straddle shelters were so pervasive that in 1978 it was estimated that more than 75% of the open interest in silver futures were entered into to accommodate tax straddles and demand for U.S.

  • Commodity Currencies and Global Trade∗
    After the Tide: Commodity Currencies and Global Trade∗ Robert Ready,y Nikolai Roussanovzand Colin Wardx October 24, 2016 Abstract The decade prior to the Great Recession saw a boom in global trade and rising trans- portation costs. High-yielding commodity exporters' currencies appreciated, boosting carry trade profits. The Global Recession sharply reversed these trends. We interpret these facts with a two-country general equilibrium model that features specialization in production and endogenous fluctuations in trade costs. Slow adjustment in the shipping sector generates boom-bust cycles in freight rates and, as a consequence, in currency risk premia. We validate these predictions using global shipping data. Our calibrated model explains about 57 percent of the narrowing of interest rate differentials post-crisis. Keywords: shipping, trade costs, carry trade, currency risk premia, exchange rates, interna- tional risk sharing, commodity trade JEL codes: G15, G12, F31 ∗We benefitted from comments and suggestions by Andy Abel, George Alessandria (the editor), Mathieu Taschereau-Dumouchel, Doireann Fitzgerald (the discussant), Ivan Shaliastovich, and conference participants in the Carnegie-Rochester-NYU Conference on Public Policy, for which this paper was prepared. ySimon School of Business, University of Rochester zThe Wharton School, University of Pennsylvania, and NBER xCarlson School of Management, University of Minnesota 1 1 Introduction The decade prior to the Great Recession saw a boom in global trade, including a rapid rise in commodity prices, trade volumes, and, consequently, in the cost of transporting goods around the world. At the same time currencies of commodity-exporting currencies appreciated, boosting the carry trade profits in foreign exchange markets (commodity currencies typically earn higher interest rates, making them attractive to investors).1 The onset of the Global Recession led to a sharp reversal in all of these trends, with only a weak recovery subsequently.

  • Forward Contracts and Futures a Forward Is an Agreement Between Two Parties to Buy Or Sell an Asset at a Pre-Determined Future Time for a Certain Price
    Forward contracts and futures A forward is an agreement between two parties to buy or sell an asset at a pre-determined future time for a certain price. Goal To hedge against the price fluctuation of commodity. • Intension of purchase decided earlier, actual transaction done later. • The forward contract needs to specify the delivery price, amount, quality, delivery date, means of delivery, etc. Potential default of either party: writer or holder. Terminal payoff from forward contract payoff payoff K − ST ST − K K ST ST K long position short position K = delivery price, ST = asset price at maturity Zero-sum game between the writer (short position) and owner (long position). Since it costs nothing to enter into a forward contract, the terminal payoff is the investor’s total gain or loss from the contract. Forward price for a forward contract is defined as the delivery price which make the value of the contract at initiation be zero. Question Does it relate to the expected value of the commodity on the delivery date? Forward price = spot price + cost of fund + storage cost cost of carry Example • Spot price of one ton of wood is $10,000 • 6-month interest income from $10,000 is $400 • storage cost of one ton of wood is $300 6-month forward price of one ton of wood = $10,000 + 400 + $300 = $10,700. Explanation Suppose the forward price deviates too much from $10,700, the construction firm would prefer to buy the wood now and store that for 6 months (though the cost of storage may be higher).

  • Arbitrage-Free Affine Models of the Forward Price of Foreign Currency
    Federal Reserve Bank of New York Staff Reports Arbitrage-Free Affine Models of the Forward Price of Foreign Currency J. Benson Durham Staff Report No. 665 February 2014 Revised April 2015 This paper presents preliminary findings and is being distributed to economists and other interested readers solely to stimulate discussion and elicit comments. The views expressed in this paper are those of the author and are not necessarily reflective of views at the Federal Reserve Bank of New York or the Federal Reserve System. Any errors or omissions are the responsibility of the author. Arbitrage-Free Affine Models of the Forward Price of Foreign Currency J. Benson Durham Federal Reserve Bank of New York Staff Reports, no. 665 February 2014; revised April 2015 JEL classification: G10, G12, G15 Abstract Common affine term structure models (ATSMs) suggest that bond yields include both expected short rates and term premiums, in violation of the strictest forms of the expectations hypothesis (EH). Similarly, forward foreign exchange contracts likely include not only expected depreciation but also a sizeable premium, which similarly contradicts pure interest rate parity (IRP) and complicates inferences about anticipated returns on foreign currency exposure. Closely following the underlying logic of ubiquitous term structure models in parallel, and rather than the usual econometric approach, this study derives arbitrage-free affine forward currency models (AFCMs) with closed-form expressions for both unobservable variables. Model calibration to eleven forward U.S. dollar currency pair term structures, and notably without any information from corresponding term structures, from the mid-to-late 1990s through early 2015 fits the data closely and suggests that the premium is indeed nonzero and variable, but not to the degree implied by previous econometric studies.

Beta (β) is the volatility of the rate of return versus the market’s average return. Underlying Sigma (σ) is the standard deviation from the average rate of returns over a specific period of Asset time. Mu (μ) is the expected return Delta (Δ) is the change in the price of the underlying asset to the corresponding change in the price of a derivative - sometimes referred to as the "hedge ratio". Lambda (λ) is ratio that measures option volatility.

    Currency Network Risk Mykola Babiak* Jozef Baruník** Lancaster University Management School Charles University First draft: December 2020 This draft: July 22, 2021 Abstract This paper identifies new currency risk stemming from a network of idiosyncratic option-based currency volatilities and shows how such network risk is priced in the cross-section of currency returns. A portfolio that buys net-receivers and sells net- transmitters of short-term linkages between currency volatilities generates a significant Sharpe ratio. The network strategy formed on causal connections is uncorrelated with popular benchmarks and generates a significant alpha, while network returns formed on aggregate connections, which are driven by a strong correlation component, are partially subsumed by standard factors. Long-term linkages are priced less, indicating a downward-sloping term structure of network risk. Keywords: Foreign exchange rate, network risk, idiosyncratic volatility, currency predictability, term structure JEL: G12, G15, F31 arXiv:2101.09738v2 [q-fin.GN] 21 Jul 2021 *Department of Accounting & Finance, Lancaster University Management School, LA1 4YX, UK, E-mail: [email protected]. **Institute of Economic Studies, Charles University, Opletalova 26, 110 00, Prague, CR and Institute of Information Theory and Automation, Academy of Sciences of the Czech Republic, Pod Vodarenskou Vezi 4, 18200, Prague, Czech Republic, E-mail: [email protected]. 1 1 Introduction Volatility has played a central role in economics and finance. In currency markets, a global volatility risk has been proposed by prior literature as a key driver of carry trade returns. While the global volatility risk factor is intuitively appealing, there is little evi- dence on how idiosyncratic currency volatilities relate to each other.

Buy forward (AT FORWARD PRICE F0) • VALUATION PRINCIPLE: NO ARBITRAGE • In perfect markets, no free lunch: the 2 methods should cost the same. You can think of a derivative as a mixture of its constituent underliers, much as a cake is a mixture of eggs, flour and milk in carefully specified proportions. The derivative’s model provide a recipe for the mixture, one whose ingredients’ quantity vary with time. Emanuel Derman, Market and models, Risk July 2001 Derivatives 01 Introduction |2 Discount factors and interest rates • Review: Present value of Ct • PV(Ct) = Ct × Discount factor • With annual compounding: • Discount factor = 1 / (1+r)t • With continuous compounding: • Discount factor = 1 / ert = e-rt Derivatives 01 Introduction |3 Forward contract valuation : No income on underlying asset • Example: Gold (provides no income + no storage cost) • Current spot price S0 = $1,340/oz • Interest rate (with continuous compounding) r = 3% • Time until delivery (maturity of forward contract) T = 1 • Forward price F0 ? t = 0 t = 1 Strategy 1: buy forward 0 ST –F0 Strategy 2: buy spot and borrow Should be Buy spot -1,340 + ST equal Borrow +1,340 -1,381 0 ST -1,381 Derivatives 01 Introduction |4 Forward price and value of forward contract rT • Forward price: F0 = S0e • Remember: the forward price is the delivery price which sets the value of a forward contract equal to zero.
