Canadian growth was flat, yet yields pushed toward 4 per cent and the TSX lost four sessions in a row. Friday payrolls showed where the Bank of Canada rate path was really being set.

Equities priced relief on Friday, but Treasury yields and USD/CAD closed higher, and the currency has done more to separate Canadian portfolio returns since August 26 than any move in the TSX.

WTI crude rose from $69.50 to $89.38 between June 30 and September 29 while USD/CAD moved from 1.4210 to 1.4188, and the widening gap between US and Canadian two-year yields tracks the currency far more closely than oil does.

The index closed September 30 at the low of the day, its lowest close since July 31. Gold futures fell 6.6% as the US 10-year yield rose 51 basis points, and First Quantum closed 15% lower on Panama news.

The TSX Composite closed September 2.85% below its August 31 level and 1.09% above its June 30 level, the ninth straight quarterly gain. Behavioural research explains why the shorter window tends to win the emotional argument.

The 3-month yield fell and the 30-year yield rose after the August PCE, while the US minus Canada 10-year spread and USD/CAD kept climbing.

The TSX closed at its lowest level since July 31, gold and materials ETFs fell 6% to 8%, and energy stocks slipped even as Brent gained 13%.

Protection against a stock decline is near a one-year low while Treasury yields sit at a two-decade high, a pairing that probability weighting and the availability heuristic help explain.

A sale on September 29 settles October 1 and restricts repurchase through October 31, while the federal tax value of the loss is smaller than the single-day move in gold on Monday.

The S&P/TSX Composite lost 0.87% on a gold selloff while U.S. yields hit levels last seen in 2007, and the Federal Reserve decision on October 28 now carries most of the weight.

Gold dropped 3.5% on a day when Middle East headlines worsened, and the gap between the safe-haven label and the price is a live test of mental accounting and loss aversion.

Five desks, one throughline. A 175 basis point gap between the Federal Reserve and the Bank of Canada moved the currency, the bond market, the mining sector and client conversations this week, while oil told a stranger story of its own.

Government of Canada 10-year yields reached 3.95 percent on Thursday, matching an August high, as markets absorb a widening gap between the Federal Reserve and the Bank of Canada that has no clear resolution before the two banks next meet.

Wednesday brought the sharpest single session decline in three months. The pattern behind client anxiety this week has a name, and it is not the index level.

A Hormuz de-escalation report lifted oil and calmed equities this afternoon. It did nothing for the Canadian dollar, because the real story today is in the bond market, not the Persian Gulf.

The Federal Reserve raised its target range to 3.75 to 4.00% on September 16, its first hike in three years, while the Bank of Canada has now held at 2.25% for seven straight announcements, and the split traces back to how each economy is absorbing the same oil shock.
