Every August we get the same note from the same desks — Jackson Hole matters because the Chair speaks, and the dollar moves on what he says." A trader we'll call the Zurich Voice — a former G10 spot desk head at a Swiss house, now retired, whom we interviewed by phone in early 2026 — said this to us with a certain fatigue. The framing has become a ritual: MUFG, Deutsche, Barclays each publish a two-scenario grid ahead of the symposium, hawkish path versus dovish path, dollar up or dollar down. It is analytically respectable. It is also, we think, the wrong shape for what Jackson Hole actually is.
Why This Is Actually True
Let us concede the case for the scenario grid in its strongest form, because the case is real.
The Kansas City Fed's symposium is one of the few pre-scheduled events in the calendar where an unelected central banker delivers a speech that has been drafted, reviewed, and staged to communicate a shift in policy stance. That is not routine. It happens at Jackson Hole in a way it does not happen at the regular FOMC podium, because the symposium is framed as a research forum — the Chair is expected to speak in the register of a scholar delivering a paper, which gives cover to say things that would be reckless to say in a post-meeting Q&A. When Bernanke previewed QE2 in his 2010 remarks, or when Powell reframed the inflation-target regime in his 2020 address, the market read the speech as policy signal and repriced accordingly. That is real. That is not confabulation.
MUFG's shape of the trade is defensible on those grounds. If you assign probabilities to a hawkish reading and a dovish reading, and you sketch what happens to DXY, EUR/USD, and USD/JPY in each, you have done the honest work of a sell-side strategist. The client desks that consume these notes need something to hedge against. A binary grid is a communication tool as much as a forecast — it forces the reader to size positions around named contingencies rather than vibes.
And the empirical case survives inspection. Enough Jackson Hole speeches in the modern archive have moved the dollar in the direction the tone suggested that the framing is not spurious. A dovish signal in an environment of tight financial conditions has, more than once, produced a measurable DXY selloff within the trading window that opened the following Monday. The framing works often enough that no sell-side risk manager is going to be fired for using it.
So the conventional read is not stupid. It is legitimate. The question is whether it is complete.
But here is what that framing misses entirely: Jackson Hole is not primarily a speech. It is a hallway.
Where It Breaks Down
The framing breaks down when the material event at the symposium is not what the Chair says on stage — but what the visiting central bankers say to each other in the hotel bar the night before.
We do not think this is a controversial claim historically. The record of the symposium's role in 1998 is the case in point, and the reason it belongs in any serious MUFG-style scenario grid that omits it. In August 1998, the Russian default was days away, the ruble was under stress the entire month, and by September LTCM would be revealed as a system-scale exposure that required a Fed-brokered private-sector rescue. The Chair's speech that August has been analyzed by the historical desks many times; it is not, in retrospect, the archive-relevant document. The archive-relevant documents are the phone logs and the informal read-outs from the sidelines — what central bankers understood about each other's balance sheets by the time they flew home from Wyoming.
The point is structural. A two-scenario grid — hawkish or dovish — treats Jackson Hole as if the informational output is one man's speech, in the same way a MiFID-compliant sell-side note treats an FOMC as one dot-plot revision. That is a category error about the venue. Jackson Hole's product is coordination visibility. The speech is what gets televised. The coordination is what gets priced.
You can see this in the pattern of dollar moves in the ten trading days after the symposium in years where the speech was uninformative. When Powell's 2019 remarks were widely read as anodyne, the dollar still moved — because Trump's trade-war tweets during the symposium weekend cross-cut what participants had told each other in Wyoming about currency intervention pathways. The scenario grid built off the speech missed the actual price driver, which came from a different information channel.
MUFG knows this. Every serious desk knows this. The reason the scenario grid persists is that "coordination visibility" is not a hedgeable variable — you cannot write a two-scenario note that says "Path A: the Governor of the BoJ tells the Governor of the ECB something we cannot see, and USD/JPY reprices Monday." That is not a client-facing product. So the desks default to the tractable framing. The tractable framing is not wrong. It is incomplete in a specific and reproducible way — the direction of the miss is when coordination beats speech, which historically clusters around stress events.
The Rule I Use Instead
Here is where it gets interesting — and I want to spend a paragraph on this because it is genuinely the load-bearing distinction, and most desk notes I read do not draw it cleanly.
The rule is: read Jackson Hole for the guest list first, the speech second.
What I mean concretely: before the symposium opens, the Kansas City Fed publishes the program, and the program lists which foreign central bank governors and BIS officials are attending. In periods when the guest list is heavy with EM central bank governors, or when the BIS delegation is unusually senior, the informational output of the week shifts. It is no longer primarily domestic Fed guidance — it is a coordination summit, and the FX read-through belongs to the currencies of the governors in the room, not to the DXY basket abstractly. The speech becomes a cover event for the real convening.
When the guest list is light on foreign officials — a Chair-heavy, academic-heavy program — the conventional grid holds. The speech IS the event, and MUFG's framing captures 80% of what will move.
The second layer: read the BIS Quarterly Review that follows the symposium. If the BIS staff use unusual language about "coordinated liquidity conditions" or "cross-border capital flow monitoring" in the review published the following quarter, retrofit that language onto the symposium week. The dollar move you saw was very often being driven by the coordination the BIS is signaling in language too dry to have been read at the time. This is boring work. It is also how you back out what actually happened.
The third layer, which is the one I care most about: a Jackson Hole scenario note that does not include a "Path C: the coordination path" is analytically incomplete for any symposium held within six months of a visible stress event — an EM funding crunch, a G10 unpeg, a sovereign yield dislocation. In placid years, two paths are enough. In non-placid years, the two-path grid is a false framing, and desks that lean on it get caught wrong-way when the actual driver is the coordination signal that leaked in the week after the meeting.
That is the rule. Read the guest list, read the BIS follow-up, insist on a third path in stress regimes.
When the Old Rule Still Wins
I want to concede this fully, because the concession matters.
In 60% of Jackson Hole years — probably more — MUFG's two-scenario grid is the right shape. The symposium is a routine research forum, the Chair delivers something between a policy signal and an academic paper, no significant coordination gets done, and the dollar moves in the direction the speech implied. The BIS review that follows is unremarkable. The guest list is academic-heavy. The scenario grid captures the trade cleanly.
In those years, insisting on a "coordination path" is analytical noise. You are chasing a signal that is not in the tape. You will look clever pre-symposium and be wrong post-symposium. The Zurich Voice reminded us of this in our conversation: "Most Augusts are not 1998. Most Augusts are just August." That is fair. The historian's temptation is to weight every event as if it might be the pivot; the sell-side strategist's job is to weight most events as if they are ordinary, because most events are.
The old rule still wins when Jackson Hole is genuinely quiet. It fails specifically when it is not — and the failure mode is directional and expensive, which is why we think the grid needs the third path in stress windows even at the cost of looking cluttered in placid ones.
*Fieldnotes: the Zurich Voice sent us a follow-up note the week after our call, unprompted, correcting one of his own remembered details from 1998 — a Wyoming hotel name he had misremembered. The historian's discipline is not accuracy from memory. It is willingness to be corrected by the archive. Second fieldnote: the MUFG August 2026 preview we read alongside this piece did in fact include a footnote about "coordination risk" — the desks are aware of the gap, but the two-scenario framing survives because the third path is unhedgeable and therefore not published. That is worth knowing.*
