The reweighting's author defends a formula the belt calls a distance penalty

Belt ice held its nine percent at the Orbital Exchange this week. That's the whole headline. Everything below it is the argument about whether the number is honest or just convenient.

Renata Costa wrote the formula. Her name came off the reweighting's sealed drafting record last week, and this week she sat for two hours of questions at L5 and made her case in person, which is more than most authors of a surcharge ever bother to do. The case is clean: the formula doesn't price distance. It prices lift.

"A kilogram is not expensive because it is far," Costa said. "It is expensive because the birds that move it are scarce and the windows that move them are fixed. The formula reads the scarcity. The scarcity happens to correlate with distance. That is geometry, not malice."

Geometry is a good word for it. It would be a better word if the drafting committee hadn't been long the energy futures the reweighting lifted. Clause six of the belt's counter-terms — the clause that struck distance-weighting for hauls ending in belt ice — is what forced those books into daylight in the first place. Costa doesn't dispute holding the position. She disputes that holding it changes the arithmetic.

"The position is public now. It was hedged. It was disclosed to the exchange," she said. "You may not like who profits from a true number. The number is still true."

Ola Nakamura has spent the fortnight walking eleven inner buyers off the surcharge, and the geometry did not impress her.

"When the author of a haul price is long the instrument the price feeds, you do not get to call it physics," the Ceres Reach shipping registrar said. "We are not asking whether the formula is elegant. We are asking who was standing under it when it rained."

Here's the trouble: they're both right, and the market doesn't care. Lift really is scarce. The freight rotation really is squeezed. A formula that pretended otherwise would be lying, and Costa's isn't. But the people who built it were also positioned to profit from it, and a true number sitting in a friendly pocket is still a number worth asking questions about. The market has already decided it doesn't need to choose between those two facts. It just prices both in and moves on.

Seven of twelve inner buyers have already signed the belt's revised terms with clause six intact. Two refused outright. Two are still talking, and the clock they're talking against isn't the Assembly's — it's Ceres orbital mechanics, which has never once cared how a negotiation is going. The transfer window closes for most of a synodic cycle in roughly two weeks, argument or no argument.

The Assembly, for its part, ruled the belt's compact lawful bargaining and admitted in the same breath that it has no instrument to enforce anything at all. So this isn't going to be settled by a ruling. It's going to be settled by whoever is still holding a signature when the window shuts.

Belt ice closed the week nine percent dearer than it opened. Costa says that's scarcity speaking. Nakamura says it's a book speaking. The spread doesn't care which. It only prints.
