Warsh's 3.75%–4% Hike Leaves BoC Trapped at 2.25%

USD/CAD traded near 1.393 on Wednesday, a two-week high, while the Federal Open Market Committee voted 12–0 to raise the funds-rate target to 3.75%–4%. That is the Toronto tape the U.S. wire did not bother to price.

The dominant story is Washington. Chair Kevin Warsh joined a unanimous hike — the first since July 2023 — and the Summary of Economic Projections put a majority of participants at another lift by year-end, even as Warsh submitted no dot of his own and said he is not in the forward-guidance business. Reuters treated the vote as an admission that White House inflation promises have not landed. Culled already framed the distillate constraint that walked into those dots: Brent near $104 and diesel at a $6.06 record, with August core CPI up 0.3 percent after gasoline did more than a third of the monthly rise.

That frame is real. It is also incomplete.

Ottawa is still at 2.25% — the next print is October 28

On September 2 the Bank of Canada held the overnight target at 2.25% for a seventh consecutive decision, Bank Rate 2.50%, deposit rate 2.20%. Governor Tiff Macklem’s statement did not match the Fed. CPI in Canada had hovered near 3% on gasoline; excluding gasoline, inflation was 2.2% in July and core sat near 2%. Governing Council left policy unchanged because activity tracked the July Monetary Policy Report, while flagging higher upside inflation risk from oil, Hormuz, and new U.S. and Canadian tariffs.

Wednesday, the same day as Warsh’s hike, Ottawa published the minutes of that hold. Reuters reported governors had already agreed near-term inflation would stay elevated, and Macklem said the Bank was prepared to raise more than once if prices stayed too high. Prepared is not done. The next scheduled overnight announcement is October 28.

The 175-basis-point overnight gap is a dated market fact until Ottawa prints again.

Measure it without metaphor. Mid-range federal funds at 3.875% against a 2.25% overnight target is about 163 basis points; the upper bound of 4.00% versus 2.25% is 175. Convera put the disadvantage at 175 basis points as USD/CAD rose toward 1.392, its highest close in a month, with the 100-day moving average near 1.393. Bank of Canada daily averages had the U.S. dollar at 1.3822 as recently as September 10. The move is the currency, not Bay Street weather.

Oil above $100 did not buy the loonie a rescue

The BoC’s own September 2 note said the Canadian dollar had appreciated slightly on dollar weakness before this week. That sentence is now stale. FX Street had USD/CAD buying for a sixth session into the FOMC, with oil above $100 failing to offset a bullish dollar, a seventh BoC hold, and a Canada–U.S. tariff round after trade talks broke. Toronto’s equity tape on Wednesday was not a crash: the TSX firmed into the decision, consumer and utility names up, energy lagging as crude eased a few dollars. The widening is in the cross, not a single S&P/TSX close.

Canadian borrowers will feel the U.S. path through that cross and through imported financial conditions. The United States has already shown how political talk about mortgage-bond purchases can move housing yields without moving the overnight rate. Canada does not get that option until October 28. Warsh’s Sintra-era reaction function is now a printed range. Macklem’s is still a hold with a warning.

What still gets mis-priced is treating $100 oil as a CAD put, or treating a modest TSX green close as proof the divergence is imaginary. The kill tests from the desk were specific: a BoC rate at or above the Fed’s, or a dollar that refused to move. Neither printed. The testable claim for the next six weeks is narrower. If USD/CAD holds above the 1.39 handle into October 28 while Ottawa stays at 2.25%, the overnight gap was the mechanism. If Macklem hikes into Warsh’s second move, the trap was a calendar, not a doctrine.
