Abstract
This case investigates when hedging does not reduce risk, but rather may increase risk.
INTRODUCTION
Metallgesellschaft Corporation (MG) is the subsidiary of Metallgesellschaft A.G., a
German conglomerate with 15 major subsidiaries closely held with over 65% of stock owned by
institutional investors including banks. In 1993, MG’s trading subsidiary, MG Refining and
Marketing (MGRM), established very large energy derivatives (futures and swaps) positions to
hedge its price exposure on its forward-supply contracts to deliver gasoline, diesel fuel and
heating oil (about 160 million barrels) to its customers over a period of ten years at fixed prices.
The counter-parties to forward contracts were retail gasoline suppliers, large manufacturing
firms, and some government entities. The central premise of their forward contracts is to supply
oil at fixed price to independent retailers who often face severe liquidity crisis and squeezes on
margin when oil prices rise. It believed it is possible to arbitrage between the spot oil market and
the long-term contract market. This arbitrage required skilled use of the futures markets in oil
products, and this was to be MGRM’s stock in trade.
THE HEDGING STIUATION
MGRM developed several novel contract programs. First, it offered a “firm-fixed”
program under which the customer would agree to a fixed monthly delivery of oil products at a set price. (102 million barrels of oil products were obligated under this program by September
1993). Second, it offered a “firm-flexible” contracts under which the customers were given
extensive rights to set the delivery schedule for up to 20% of its needs in any year, besides the
fixed price commitments. (A total of 52 million barrels were contracted under this program).
Third, it offered a “guaranteed margin” contracts under which it agreed to make deliveries at a
price that would assure the independent operator a fixed margin relative to the retail price offered
by its geographical competitors. The contracts could be extended annually for a defined period
and at MGRM’s discretion. This means they were not firm obligations. (By September 1993, a
total of 54 million barrels were committed under this program.) It is the first two programs
involving 154 million barrels of obligations for periods up to ten years that constituted MGRM’s
designated short position in oil.
Most of the forward contracts were negotiated during the summer of 1993 when energy
prices were low and falling and the contracts came with cash-out option if the energy price were
to rise above the contractually fixed prices. The fixed delivery prices were set 3 to 5 dollars
higher than the spot price when writing the contracts. Under the cash-out provision, the buyer
could choose to sell the remainder of its forward obligations back to MGRM for a cash payment
of one-half the difference between the prevailing near month futures price and the contractually
fixed supply price times the total volume remaining on the contract. MGRM opted for early

exercise sell-back options instead of negotiated unwinding. These options take effect when the
front-month futures rises above the fixed delivery price in the flow contract. Although
customers might wish to exercise these sell-back options, if they expect spot prices in the future
to fall, they might well wish to do so even if they regarded a surge in spot prices as permanent.
Remember, that they must compare the immediate cash payment with the PV of expected future
difference between spot prices and the delivery prices over the remaining life of the contract.
EXPOSURE
MGRM’s fixed price forward delivery contracts exposed it to the risk of rising energy
prices. MGRM hedged this price risk with energy futures contracts of between one to three
months to maturity at NYMEX and OTC swaps. The objective of its hedging strategy was to
protect the profit margins in its forward delivery contracts by insulating them from increases in
energy prices. MGRM would gain substantially from its derivative positions if the energy prices
rise. During the later part of 1993, however, energy prices fell sharply ($19 a barrel in June 93 to
$15 a barrel in Dec. 93) resulting in unrealized losses and margin calls on derivative positions in
excess of $900 million. To complicate the matter, the futures market went into a contango price
relationship for almost entire year in 1993 increasing cost each time it rolled its derivatives. The
MG’s Supervisory Board responded to the situation of mounting margin calls by replacing MG’s
top management and liquidating MGRM’s derivative positions and forward supply contracts
which ended MG’s involvement in the oil market. It suffered derivative related loss of $1.3
billion by the end of 1993. The new management team declared that “speculative oil
deals…..had plunged MG into the crisis…..” Only a massive $1.9 billion rescue operation by
150 German and international banks kept MG from going into bankruptcy.
One reason for not buying forward contracts for the same maturity is that market for
long-dated oil contracts is small - only about 10 firms made prices in this market. Another reason
is that the MG’s credit rating was low enough for those firms to be exposed to it for long.
(Economist) If energy prices had risen rather than fallen, MGRM would not have had a problem.
It would have had unrealized gains on its derivatives position, and positive margin flows from
the forward contracts. Although it would have had unrealized losses on its forward contracts, it
would not have mattered as it would be offset by the unrealized gains on its derivative positions.
MGRM’s hedging strategy included short-dated energy futures contracts and OTC swaps
– a “stack and roll” or “rolling stack” strategy. Under this strategy, MGRM opened a long
position in futures staked in the near month contract. Each month MGRM would roll the stack
over into the next near month contract, gradually decreasing the size of the position. Under this
plan the total long position in the stack would always match the short position remaining due
under the supply contracts. It bought long futures positions on the NYMEX (equivalent to 55 m.
barrels of gasoline, heating oil and crude oil) and entered into OTC energy swaps (100 to 110 m.
barrels) with swap dealers (mostly banks) entitling it to receive payments based upon floating
energy prices while making fixed payments. MGRM’s total derivative’s position was almost
equal to its forward commitments, a barrel for barrel hedge or with hedge ratio of one. The
short- term nature of the derivatives called for continuous roll forward to maintain the hedge
position. This exposed the firm to rollover risk. A stack hedge refers to a futures position being
“stacked” or concentrated in a particular delivery month (or months) rather than being spread
over many delivery months. The stack and roll strategy can be profitable when markets are in
“backwardation,” that is, when spot prices are higher than futures prices. But when markets are
