CASE STUDIES / OPTIONALITY · MAY 2025
At forward prices the Asia DES-Long option adds nothing and would be easy to concede. Simulated across a thousand paths, it is worth millions, rising sharply with volatility.
$8.6M
WHAT A RIGHT WORTH $0 AT TODAY'S CURVE EARNS ACROSS 1,000 SIMULATED PATHS · $13.3M IN STRESSED MARKETS
01 · THE TWO BOOKS
The flexibility is measured as the difference between two portfolios that are identical in every respect except one: the Asia-Flex book may also source six DES-Long cargoes in Asia. The indexations are deliberately set so all six start out of the money, with the most profitable one just at the money.
THE BASE BOOK · 2026 TO 2027
THE ASIA-FLEX BOOK · ONE ADDITION
FORWARD CURVES AND SIMULATIONS FROM 21 MAY 2025 · HORIZON 2026 TO 2027 · PER-MMBTU VALUES ON 22.2M MMBTU (6 X 3.7M)
02 · AT THE CURVE
Run against today's forwards, both books produce the same plan and the same profit to the dollar: $188,895,430, with no Asia cargo matched. A price-only view puts the exercise threshold out of reach, and every forward point sits outside the exercise region. That is where most valuations stop.
03 · UNDER SIMULATION
Three thousand price paths, a thousand per volatility regime, each one re-optimised for both books. The base book rises above its forward value on its own; the Asia-Flex book rises further, and the gap between them is the option.
04 · THE VALUE
The same clause is worth six hundred thousand dollars in a calm market and thirteen million in a stressed one, a factor of twenty. An option that looks worthless today is a volatility position, and conceding it in a negotiation gives away the part of the book that pays when planning gets hard.
05 · THE EXERCISE
Counting matched Asia cargoes per path shows the mechanics behind the averages. In calm markets the book rarely goes beyond two; regular volatility clusters at three to five; under stress the distribution shifts back towards two and three as the whole book is re-planned around the wider spreads. All six cargoes are never matched at once.
06 · THE VERDICT
An option worth nothing at the curve is worth $8.6M in regular markets:
and $13.3M in stressed ones.
Extrinsic value is invisible to a forward-curve check and visible to a simulation. That difference decides whether a flexibility clause gets defended or traded away for free.
07 · TAKEAWAYS
Zero at the curve is not zero
Both books earn exactly $188,895,430 at the forward curve and no Asia cargo is matched, so a static valuation prices the clause at nothing. Across simulations it is worth $8.6M in regular markets.
Volatility is the value driver
The same right is worth $0.6M under low volatility and $13.3M under high, $0.03 against $0.60 per MMBtu. Optionality pays precisely when the market becomes hard to plan for.
Price spreads alone misprice the option
The JKM-TTF decision boundary is only the starting point: shipping cost differentials, boil-off volume losses and vessel availability all move the exercise threshold, and exercising re-optimises the whole book. All six cargoes are never matched at once.
