The Federal Reserve raised its benchmark policy rate by 25 basis points to a target range of 3.75 to 4.00 percent on Wednesday, the first increase since 2023. The vote was unanimous. The move had been signalled for weeks, both in projections the Committee itself published in June and in economist surveys through August.
None of that stopped the Dow Jones Industrial Average from falling 631 points, a decline of 1.21 percent, while the Cboe Volatility Index jumped to 17.71 from 17.20 a day earlier. A quarter point increase priced into markets for a month produced a reaction better suited to a surprise.
The Anchor That Broke
Behavioral economists Daniel Kahneman and Amos Tversky, publishing in 1979, described how investors weigh a loss more heavily than an equivalent gain, a pattern known as loss aversion. A second pattern compounds it here: the availability heuristic, in which a vivid label, in this case first hike since 2023, makes an event feel more consequential than its actual size warrants. Three years without an increase turned a routine quarter point move into a headline investors could not easily dismiss.
Options traders priced in more fear after the Wednesday decision than the size of the move alone would explain, with the VIX index breaking above 17 for the first time in five weeks.
The VIX climbed from a one-month low of 14.32 on September 3 to 17.71 after the Federal Reserve raised its policy rate for the first time since 2023. The increase had been flagged in projections the Committee itself published weeks earlier.
The Canadian Read Through Advisors Are Missing
Canadian portfolios felt Wednesday even though the Bank of Canada did nothing new. The Bank held its policy rate at 2.25 percent on September 2 for a seventh straight decision, while the Fed increase widened the gap between the two rates to 175 basis points at the upper bound, the widest since the current hold began. Capital does not need a Canadian catalyst to move against the loonie: a rate story anywhere in North America now reaches TSX listed portfolios through the currency.
The behavioral pattern here is not limited to the trading floor. Clients who have spent three years anchored to a low rate regime are now processing a genuine regime change, and the emotional reaction is arriving before the analytical one.
The research offers a practical test: ask whether the reaction would make sense if the decision had been unflagged. If not, the emotional response is the primary story to manage, not the policy shift itself.
Advisors who can name the mechanism, three years of anchoring meeting a well flagged but still unfamiliar move, are positioned to shorten the gap between a first reaction and a considered one.
