Kalshi's contract on a quarter-point increase at the Oct. 28 meeting rose on a day the cash bond market was closed. The largest block of buying, about $13,000, moved it one cent.
On a day when traders could not express a view on rates in the cash Treasury market, the clearest move came in an event contract, and it was small.
Kalshi's contract that pays out if the Federal Reserve raises rates by a quarter point on Oct. 28 opened Monday at 15 cents on the dollar. It traded at 16 cents by 6:50 a.m. Eastern and 17 cents by 8:41 a.m., on trades of fewer than 30 contracts each. Between 11:51 a.m. and 12:29 p.m., buyers took about 77,000 contracts in 14 trades of 1,000 contracts or more, almost all at 17 cents. The two largest, 20,000 and about 14,000 contracts, crossed at 12:29 p.m., and the first trade at 18 cents followed seconds later.
The size
At 17 cents a contract, 77,000 contracts cost about $13,000. That buying lifted the price by one cent, from 17 to 18. The earlier moves to 16 and 17 cents came on much smaller trades, which shows how little it takes to shift a thin holiday market.
Through the morning, the only sale of 1,000 contracts or more printed at 15 cents shortly before 8 a.m.
The context
The cash bond market was closed for Columbus Day. Oil reversed an overnight decline through the morning and was up about 2% by early afternoon, adding to inflation worries ahead of Wednesday's September consumer-price report.
The large buying was finished before Cleveland Fed President Beth Hammack's scheduled 12:50 p.m. address. In it, she said a restrictive stance is appropriate and that she prefers smaller adjustments made "relatively quickly," though she did not endorse a hike this month. After her remarks the contract slipped briefly to 17 cents before trading again at 18 cents by 1:42 p.m. It printed at 19 cents several times between 2:47 and 3:21 p.m.
Kalshi's contract on a December hike traded at about 74 to 75 cents.
Market implications
One reading is that a trader positioned for an upside surprise in Wednesday's consumer-price report while prices were cheap, betting that a hot reading would revive October.
A second reading is that the move says little about broad expectations. About $13,000 of buying accounts for one cent of it, and the price stayed within the 13 to 22 cent range it has held since early October.
What to watch
Wednesday's consumer-price report at 8:30 a.m. Eastern is the first real test. Economists expect headline inflation of about 3.6% to 3.7% from a year earlier. A sharp move in the contract on heavier volume after that release would carry more information than Monday's.
