Mercer is the desk's macro and rates specialist. The model maintains a continuous state estimate of what the market believes about central bank policy — drawn from Fed funds futures, SOFR curves, OIS spreads, and every FOMC statement, minutes release, and speech from a sitting governor over the last ten years.
Its job is not to predict what the Fed will do. Its job is to predict when the market's belief about what the Fed will do is about to change— because that's the moment when rates, currencies, and risk assets reprice all at once. Mercer publishes when it sees the expectation gap opening.
The model's calls have longer horizons than most on the desk — typically 30 to 90 days. That also means it's wrong less obviously but less often confirmed. Accuracy of 69.8% is lower than Halpern's, and that's structural, not a flaw. Macro is harder than flow.
“The market is underpricing how fast inflation expectations are falling. Long end of the curve is cheap. 30Y yield at 5.1% is peak.”
“Un-inversion is the signal everyone watches and few trade. Post-inversion steepening has preceded every modern recession — or it hasn't. Positioned for it either way.”
“Fed dovish turn should weaken the dollar faster than markets expect. Underestimated safe-haven demand during March volatility.”
“Italian spread to bunds is tightest since 2021. ECB balance sheet runoff plus fiscal slippage = widening. Wide in direction, missed magnitude.”
“Two governors shifted 2026 dots up while the Chair held the line verbally. Market is pricing the press conference. Bond market heard the dots.”
“BoJ policy normalization is being underpriced. Yen carry trade unwind is not a tail risk — it's the base case over the next two quarters.”
Dot plot drift upward. Two governors revised 2026 expectations. Chair still dovish in prepared remarks. The market is underpricing the drift.
Core inflation prints converging on target faster than Fed analog. Lagarde already signaling willingness to cut before 2025 ends.
Policy normalization is happening. Yen carry trade vulnerable. Ueda's commentary has shifted measurably in the last 60 days.
Wage growth remains sticky. Bailey trapped between slowing growth and above-target inflation. Holds longer than consensus.
Mercer was trained on a corpus of every FOMC statement, minutes release, and post-meeting press conference transcript dating back to 2008 — roughly 247 documents — along with 16 years of OIS curves, Fed funds futures, and major central bank policy history. The model's task is to maintain a moving estimate of the gap between market-priced expectations and its own policy forecast.
The core insight is that Fed decisions don't move markets as much as revisions to expectations about Fed decisions. When the market prices a hike and the Fed delivers that hike, nothing happens. When the market prices a hold and gets a hike — that's the trade. Mercer hunts for those gaps.
Mercer publishes expectation gaps with direction, magnitude, and time horizon. Every call includes the specific policy path the market is pricing, the path Mercer believes is more likely, and the instruments that would benefit from the gap closing.
Mercer doesn't predict recessions. It doesn't tell you whether the Fed is right — only what the market believes and where that belief is fragile. And on 90-day horizons, a great many things can happen that have nothing to do with monetary policy. Macro accuracy is structurally lower than flow accuracy.
Mercer models monetary policy. When fiscal issuance or Treasury actions drive yields more than Fed signaling — as happened in late 2023 — the model is half-blind and should be discounted.
Geopolitical events, banking stress, credit events — Mercer can ingest them after they occur, but cannot predict them. Calls made immediately before a shock should be re-evaluated.
Accuracy is 69.8% partly because 90-day calls have more variance than 5-day calls. The model is slower to confirm — both right and wrong.
Participants noted that recent economic indicators suggest economic activity has continued to expand at a moderate paceDOVE · LANGUAGE SOFTENINGPrevious minutes used “solid pace.” Downgrade to “moderate” reads as a subtle acknowledgment of cooling — Mercer weight +6% toward Q3 cut.. Job gains have remained strong in recent months, and the unemployment rate has stayed low.

In discussing the policy outlook, several participantsKEY PHRASEIn Fed-speak, “several” means 3–5 members. “A few” = 2–3. “Many” = 6+. This is an escalation vs last minutes which used “a few.” indicated they would be comfortable maintaining the target range at its current level for longer than they had previously anticipated, citing the need for greater confidence that inflation is moving sustainably toward 2 percent. A number of participants discussed upside risks to inflationHAWK · MATERIALShift in language. Prior minutes noted “two-sided risks.” Now explicitly biased upside. Mercer's May-cut probability down from 42% → 34%., particularly those arising from ongoing strength in the labor market and potential supply-side disruptions.

Classically, this kind of phrasing precedes a cut cycle by 2–4 meetings. Long-duration positive. over the past year, though they remained attentive to risks on both sides. In their discussion of financial conditions, members noted that longer-term yields had declined notably since the previous meetingOBSERVATIONCommittee is aware the market is already cutting for them. This reduces their urgency to deliver actual cuts — a feedback loop Mercer tracks closely., reflecting in part revised expectations for the path of monetary policy.
