Rumpus Daily, 20 Oct 2026: Traders now expect a Bank of Canada rate rise this month

In this episode: Traders now expect a Bank of Canada rate rise this month; Traders pull back from the Perim Island bet. Two stories. First, Canada's inflation hit three-point-one per cent last month, and traders have priced a Bank of Canada rate rise at seventy-three per cent. Petrol drove the number, and we think a hold is more likely than that price suggests.

Opening

Sheema: Good morning and welcome to The Rumpus Daily. I'm Sheema Sharti.

Neil: And I'm Neil Matthews. Every weekday we bring you the signals from the world's prediction markets. Today is Tuesday, October twentieth.

Sheema: Two stories. First, Canada's inflation hit three-point-one per cent last month, and traders have priced a Bank of Canada rate rise at seventy-three per cent. Petrol drove the number, and we think a hold is more likely than that price suggests. Second, traders have cut their bet that the Houthis lose Perim Island, an island they currently hold, from seventy-seven per cent ten days ago to twenty-eight per cent today. We think twenty-eight is still too high.

Neil: On Canada, the equity market is reading the hike as real. TSX futures eased on the rate outlook.

Sheema: Let's start there.

Traders now expect a Bank of Canada rate rise this month

Sheema: Traders now expect a Bank of Canada rate rise this month. Polymarket runs a bet that pays out if the bank raises by a quarter of a percentage point, and traders price it at seventy-three per cent, roughly the odds they give a hike. That contract sat at fourteen per cent on October thirteenth and hit eighty-five on the nineteenth. Kalshi, a separate market, has the same outcome at seventy-eight. Two books broadly agree.

Neil: The trigger is Statistics Canada's inflation reading. Prices rose three-point-one per cent in the year to last month, breaching the Bank of Canada's target. If energy costs spread into wages and other prices, the bank has a strong case to move.

Sheema: Does that argument hold when petrol drove the whole print? Economists quoted by The Star said energy costs are still contained. A rate rise adds no oil to the market.

Neil: Fair. But the bank has to decide whether to wait it out or get ahead of it. What does the retreat from eighty-five to seventy-three tell you?

Sheema: The fall from eighty-five to seventy-three suggests some traders have reached the same view. The no-change contract on Polymarket sits at twenty-two per cent. Our call is that the bank holds on October twenty-eighth, and twenty-two underrates that. Wrong if the bank raises on the twenty-eighth.

Traders pull back from the Perim Island bet

Neil: Traders pull back from the Perim Island bet. The Houthis are also called Ansar Allah. The bet that they lose Perim Island by December thirty-first has fallen from seventy-seven per cent on October tenth to twenty-eight per cent today.

Sheema: We said ten days ago that seventy-seven was too high. What has changed?

Neil: Traders gave a takeover this month only five per cent, so the December price rests on November and December alone. That means a force landing on the island, taking it, and holding it, all within seventy-three days. Is twenty-eight per cent fair for that task?

Sheema: It isn't. Taking an island is harder than the original price implied. The only scenario that makes twenty-eight look cheap is a credible report of a landing on Perim in November, and nothing in the price path, meaning how the odds moved, points to one. The Houthis hold through December thirty-first. Wrong if a credible report before that date says otherwise.

Close

Sheema: Neil, thanks very much.

Neil: Thanks, Sheema.

Sheema: That's The Rumpus Daily for Tuesday, October twentieth. We'll see you tomorrow.
