Goldman sees bumpier markets if Warsh steers Fed away from guidance

By disclosing less about its policy path, the Fed would push more weight onto incoming economic data, leaving the dollar, short-dated Treasuries and rate-sensitive equities exposed to outsized moves whenever a major release lands — this week's CPI reaction is an early illustration. Even if the Fed sticks to the projected course of a single December hike, Treasury-market volatility could stay high. Energy is a key swing factor in that world: the Iran war is keeping oil prices high, so every change in crude quickly flows into inflation expectations and, with less Fed guidance to hold them steady, into interest-rate pricing. Gold probably continues to take its cues from yields and tightening bets rather than from headlines about geopolitics.

Warsh would rather have investors focus on the economy than on the Fed, but 15 years of being guided by the hand suggests the first unaided steps could be shaky.

In summary:

• Five task forces have been established by Warsh — one devoted to communications — and his goal is for the Fed to hold back more of its internal deliberations.
• He is against telling markets in advance whether rates will be raised, cut or left alone at future meetings.
• Goldman's Investment Strategy Group sees the likely changes arriving slowly, while cautioning that policy could take longer to bite and volatility could rise.
• Market pricing for rates has already lurched on economic figures — odds of an October hike tumbled in late September and yields spiked following this week's CPI.
• A further December rate rise is the expectation at most large banks.
• Warsh is due to speak in Bangkok on Friday, just before the FOMC gathers on 27–28 October.

Investors have spent more than a decade learning to parse every Fed utterance. Warsh wants to end that dependence, and Goldman Sachs is cautioning clients that taking markets off the guidance habit has costs — policy lags may lengthen and volatility could increase.

The Federal Reserve chair has created five task forces to review the central bank's operations, and on Friday he is scheduled to address the IMF and World Bank meetings in Bangkok. The groups look at communications, the balance sheet, data sources, productivity and jobs, and the inflation framework. Of those, the communications review is most likely to reshape how markets trade. Warsh believes the Fed should reveal less of its internal thinking, letting investors form their own economic picture — analogous to watching the game rather than following the match official. He has also said that he is opposed to indicating in advance whether rates will go up, down or stay put at upcoming meetings.

Goldman's Investment Strategy Group, in its most recent quarterly client note, predicted the task forces would probably deliver change incrementally. It did, however, echo a worry heard from some market participants: the less the Fed says, the more time policy may need to pass through financial conditions, and the ride could be rougher for markets and the broader economy alike.

The reasoning is simple enough. For years, forward guidance has functioned as a policy instrument in its own right. A clear Fed signal on the path ahead lets bond yields, mortgage rates and the dollar shift before a decision is even announced, effectively delivering some tightening or easing early. Without those signals, markets have no choice but to await the data and the actual decisions before repricing. The result can be sharper reactions to major releases and more frequent repricing between meetings.

Late September offered an early example: futures pricing for an October hike dropped from around 70% to below 40% over the course of a week as benign inflation figures and a senior Fed official's comments shifted the landscape. At the start of the month, Goldman itself moved its predicted next hike from October to December. Then came this week's hotter-than-expected consumer price data, which lifted Treasury yields sharply as traders increased their wagers on further tightening.

When the Fed raised rates in September — its first such move since 2023 — it attached a statement that gave no explicit steer on what comes next. As a result, investors are depending largely on economic releases and individual policymakers, with regional presidents like Beth Hammack of Cleveland stepping in to offer their own perspectives.

There is something to Warsh's argument. Over-reliance on guidance can trap a central bank in a course the incoming data have stopped justifying, and it can lead traders to wager on the Fed's next move instead of the underlying economy. When investors do their own legwork, risk may be priced with greater accuracy. But the cost is a transition phase — one in which markets are relearning how to interpret the economy without a pre-written script — that is apt to be messy.

In practical terms for traders, the result is a framework where economic reports carry extra weight and Fed meetings play a different role. The biggest exposure is likely to sit with the dollar, short-dated Treasuries and rate-sensitive equities. Even if the Fed follows the path Wall Street broadly expects, Treasury volatility could remain high, since most large banks are looking for only one additional rate rise in December.

The Bangkok speech on Friday will be an early test. Should Warsh stay on message and say almost nothing about October, investors will be left to form their own judgment before the Fed's gathering on 27 and 28 October — and that is precisely the outcome he wants.
