A September rate increase is now the base case in Charles Schwab's internal data, and the strategist who flagged it says the bigger risk for markets is what comes after — a tightening cycle that does not stop at one meeting.
"Her data is suggesting a likely interest rate hike," Liz Ann Sonders, chief investment strategist at Charles Schwab, said, adding that she is gauging what investors should expect if September's tentative hike is the first of several. The comment places the burden of proof on the inflation data rather than on Fed communication, which has not yet committed to a move.
The transmission chain runs through the front end of the curve first. A hot CPI print lifts two-year yields, steepens the discount-rate pressure on long-duration equities, and widens the gap between market pricing and the Fed's own projections. The last time inflation data forced a comparable repricing, rate-sensitive growth and technology names absorbed the first and largest drawdown, with the drag broadening into the major US indices only after the second consecutive upside surprise.
That sequencing matters because the September decision is not being framed as a single event. If the Fed hikes and signals more, the discount-rate shock is persistent rather than one-day; if it hikes and stops, the move is largely priced and the equity reaction fades within days. The difference between those two outcomes is the entire debate now occupying portfolio managers.
Positioning is already adjusting to that ambiguity. Investors who spent the past year buying dips on the assumption that tightening had ended now have to price a cycle that may be restarting, which changes the calculus for duration-heavy holdings, rate-sensitive sectors, and any position whose valuation depends on a falling discount rate. The repositioning itself becomes a source of index-level volatility before the Fed even meets.
The CPI release is the near-term trigger, and the September FOMC meeting is the pivot. Between those two dates, every inflation component — headline, core, and the services sub-indices that have proved stickiest — carries outsized weight in setting the path for yields, the dollar, and equity multiples. A soft print would deflate the hike case quickly; a firm one would harden the multi-hike narrative that Sonders raised.
