Markets follow people

Does trust in a person who holds a public office, a central bank chair, a finance minister or a head of government, move markets? The evidence gathered for this thread says yes, under a condition: markets follow a person where that person’s word is the binding next step, or where the institution behind the person cannot be seen to say no. The effect is strong for minutes and days and across several markets at once, and thin over years. In the case that prompted the question, the US Treasury in the autumn of 2026, the pattern does not show.

A research thread. Evidence gathered on 14 and 15 October 2026, published on 22 October 2026. It names offices and dates, not persons. A watch for November 2026 was written down before the events it will read.

Why the question is here

Holagram holds that a decision rests on accounts, each drawn from where some agent stands, and that what an account is worth depends partly on who stands behind it. A market is an unusual place to watch this. An office speaks, and within seconds thousands of agents answer in prices, in public and in numbers. The question put to the evidence was whether, in a market that follows people, people matter more than models, and what that says about the human side of the practice. The answer is narrower than the question.

The short answer

What the evidence shows

Five kinds of episode, with the figures that survived checking. Moves run from one daily close to the next unless a window is given. A basis point (bp) is a hundredth of a percentage point. The grades: A, a peer-reviewed or central bank event study with a tightly dated window; B, press of the day or primary data at the daily close, with the other causes that day listed; C, a long series with no event day. No case from 2025 or 2026 reaches A, because daily closes cannot separate one move inside a day from another.

Appointments, removals and exits

EpisodeWhat movedGrade
South Africa: the finance minister dismissed on 9 December 2015, and a former minister appointed four days laterThe rand nearly 9 per cent weaker over the week, bank shares nearly 20 per cent lower and the benchmark bond yield up nearly 200 bp in two days. On the day of the second appointment the rand rose 5 per cent and the yield fell 107 bp. A rating cut five days earlier is part of the picture.B
Turkey: the central bank governor removed by decree on 20 March 2021, two days after a 200 bp rise in the policy rateThe lira about 15 per cent weaker at the low and 10 to 11 per cent at the close, while peer currencies barely moved. The move bundles the person with the rate cuts the successor was expected to make.B
United States: a surprise announcement on 2 June 1987 that the Fed chair would not serve another termThe 10-year yield up 27 bp in a day and the dollar 1.65 per cent lower against the mark. By 5 June, 22 of the 27 bp had gone.B
United States: the nominee for Fed chair named on 30 January 2026Gold down 9.8 per cent and silver by more than a quarter in a day, the dollar index up 0.8 per cent, the 10-year yield up 2 bp. It coincided with the end of a steep rise in metals, and part of the move came before the announcement.B
United States: the president’s heart attack, announced on Saturday 24 September 1955The Dow about 6.5 per cent lower on the first trading day, and about two-thirds of it regained within two days. Nothing had changed but the person’s continuity.B
Fifteen countries: announcements of new central bank heads and unscheduled departuresUnexpected appointments move exchange rates, and less strongly bonds and shares. Anticipated ones produce no significant reaction, and there is no consistent direction (Kuttner and Posen 2010).B

Words

EpisodeWhat movedGrade
Euro area: the ECB president, speaking in London on 26 July 2012, said the bank would do what was needed to preserve the euro, and named no instrumentItaly’s 2-year yield fell 83 bp that day in a central bank event study (72 bp after controls), Spain’s 77 bp. Over the three announcements of July to September, Italy’s fell 175 bp and Spain’s 209 bp after controls. The programme the words pointed to was never used. The words named a backstop, so the person cannot be separated from the bank’s firepower.A
United States: the Fed chair said on 22 May 2013 that asset purchases could be stepped down, and set out a timetable on 19 JuneThe 10-year yield up 9 bp and 13 bp on the two days, and from 1.66 per cent on 1 May to 2.98 per cent on 5 September. The New York Fed and the primary dealers read it as news about policy, not as a loss of trust in the chair.B
United States: a short speech by the Fed chair on 26 August 2022 restating resolve on inflationThe S&P 500 down 3.37 per cent while Treasury yields barely moved (2-year up 2 bp). Shares moved on words that restated policy without changing it.B
Euro area: at a press conference on 12 March 2020 the ECB president said closing spreads was not the bank’s function; the bank clarified the same dayItalian shares 16 to 17 per cent lower, inside a global crash that confounds the reading.B
United States: the new Fed chair’s first set-piece speech, 28 August 2026The 2-year yield from 4.20 to 4.34 per cent (up 14 bp), the 10-year up 6 bp, the dollar up and gold down. A new chair’s first speech repriced the front of the curve.B
Event studies of the voiceStatements carry most of the move in 2- to 10-year yields around Fed announcements (Gürkaynak, Sack and Swanson 2005). The chair’s speeches matter more than the announcements for all but the shortest maturities (Swanson 2023). A more positive tone of voice raises share prices (Gorodnichenko, Pham and Talavera 2023), and negative facial expressions move a share index fund by about half a basis point per three minutes, fading within ten (Curti and Kazinnik 2023). The market reads the person, literally, and what it reads is mostly the path of policy.A

Threats to independence

EpisodeWhat movedGrade
United States: from 17 April 2025 the president called for the Fed chair’s removal; on 22 April he said he had no intention of firing himThe S&P 500 down 2.36 per cent on 21 April and up 2.51 per cent on 22 April. Gold at a record. From 17 to 21 April the 2-year yield went from 3.81 to 3.75 per cent and the 30-year from 4.80 to 4.91; the dollar fell 0.7 to 1.1 per cent depending on the index; inflation compensation did not move. The cleanest event and reversal in the set, in a week full of tariff news.B
United States: on the evening of 25 August 2025 the president announced the removal of a Fed governor; the courts later blocked itOvernight the 30-year yield rose 4.7 bp and the 2-year fell 1.3 bp. By the US close on 26 August the 2-year was down 12 bp and the 30-year up 1 bp, and shares had barely moved. A dovish speech by the chair four days earlier, a strong 2-year auction and new tariff threats fall in the same window.B
United States: on 11 January 2026 the Fed chair said the Justice Department had served the Fed with grand-jury subpoenasGold up more than 1.5 per cent to a record, silver up 5 per cent, the dollar index 0.2 to 0.4 per cent lower. The 10-year yield up 1 bp and the 2-year unchanged. The protest was in metals and the dollar, not in Treasuries.B
United States, 2015 to 2021: the president’s public calls for lower rates, studied with futures data in five-minute windowsExpected policy rates and long yields fell, and shares did not move significantly (Bianchi, Gómez-Cram, Kind and Kung 2023). Pressure was priced as easing, at a time when independence was not in doubt and inflation was low.A
United Kingdom, 23 September to 17 October 2022: about £45 billion of tax cuts presented without the official fiscal forecast, then reversedThe 30-year gilt yield up more than 270 bp from 1 August to the peak on 14 October. The Bank of England’s own papers tie the repricing to the fiscal announcement and its amplification to pension funds’ leveraged strategies, and do not frame it as lost trust in individuals.A
Longer horizonsPressure on the Fed to ease raises prices strongly and persistently, with no gain in output (Drechsel 2026). After politically motivated appointments of unorthodox governors, forecasters’ long-term inflation expectations rise about a percentage point more over two years than after other changes (Bolhuis, Mano and Thorell 2026). Legal independence goes with lower local-currency yields in emerging markets (Alter and others 2026, an association and not a causal estimate). The strongest long-run evidence concerns independence, not a named person.B

Credibility earned, slowly

EpisodeWhat movedGrade
United States, 1979 to 1986: a new Fed chair appointed on 25 July 1979, and a change of policy on 6 October 1979The 10-year yield fell 7 bp on the appointment and rose 33 bp on the first day after the change of policy. It peaked at 15.84 per cent on 30 September 1981 and went back below its August 1979 level only on 13 February 1986. Long yields stayed high for years because credibility was imperfect (Goodfriend and King 2005).B for the day, C for the path
What chairs believed, and what regimes didWhat the chair and others at the Fed believed about how the economy works has been the main determinant of the quality of US policy since the 1930s (Romer and Romer 2004). Yet the best-fitting model of US policy since 1959 shows no change of policy rule at changes of chair (Sims and Zha 2006). Both can hold if beliefs act inside a regime that lasts.B

Voice and provenance

EpisodeWhat movedGrade
7 April 2025: a small account posted that a White House adviser had said tariffs would be paused; he had notThe S&P 500 swung from 4.7 per cent down to 3.4 per cent up in the first hour, and closed 0.2 per cent down. Most of the reversal came before the White House denied the report.B
23 April 2013: a hacked news agency account reported explosions that had hurt the presidentThe Dow 143.5 points lower within minutes, recovered the same day.B
22 May 2023: an invented picture of an explosion near the PentagonThe S&P 500 about 0.3 per cent down at the low, and flat by the close.B
7 August 2018: a company’s chief executive posted that funding was secured to take it private; the regulator alleged the post was untrueThe shares closed 6.42 per cent above the price just before the post, and trading was halted for about 90 minutes. The one case isolated on a timestamp; it concerns a company, not a government.A
Machine readersIndex prices react to macroeconomic releases within about five milliseconds (Chordia and others 2018). Language models classify the stance of Fed statements better than the methods in common use (Hansen and Kazinnik 2024). Central banks have warned of deepfakes of their governors used in scams, and the answer to fakes so far has been checking by hand, not technical provenance.B

Where it does not show: the Treasury, autumn 2026

The case that prompted the question. The 10-year yield first closed above 5 per cent on 16 September 2026, and commentary asked whether the market was testing the Treasury Secretary. Closing par yields from the US Treasury, in per cent, with the change in bp.

DatesWhat happened2-year10-year30-year

16 to 17 SepThe Fed raised its target range by a quarter point to 3.75 to 4.00 per cent, 12 votes to none. Yields fell the next day.4.74 to 4.67 (−7)5.01 to 4.94 (−7)5.35 to 5.29 (−6)
9 to 30 SepThe month as a whole.4.43 to 4.88 (+45)4.83 to 5.29 (+46)5.28 to 5.64 (+36)
5 OctThe highest 10-year close so far.4.845.315.66
14 OctSeptember consumer prices published, 3.7 per cent up on the year.4.825.195.52

Over 9 to 30 September, from public series on FRED, computed by a scout and recomputed by an auditor: the 10-year real yield rose 47 bp, 10-year inflation compensation was flat (2.37 to 2.36 per cent), a model estimate of the 10-year term premium rose 18 bp, the broad dollar rose 2.6 per cent, Brent crude rose 5.8 per cent, and the S&P 500 was roughly flat.

The reading. The first leg looks like a test of resolve in a plain sense: the Treasury acted, the market gave relief on the day and took it back within two sessions. The month is better explained by interest rates: an oil shock, inflation at 3.7 per cent and a Fed that raised rates. If the market had been withdrawing trust from the Treasury, long yields would have risen faster than short ones and the dollar would have fallen. Instead the 2-year rose as much as the 10-year and the dollar rose 2.6 per cent. The rise in the term premium leaves room for some doubt about how the debt is managed, and daily data cannot separate the two. The verdict is “not shown”, which is not the same as “shown false”.

Reading the signature

If the story after a price move is that trust in a person or an institution was lost, it predicts a pattern across markets, and the pattern can be checked at another distance than the story. The table is this thread’s reading of the cases above, not a result from the literature.

SignatureWhat it suggestsWhere it appearsWeak point
Long yields up or flat, short yields down, dollar down, gold up, shares downDoubt about an institution’s ability to say no.21 April 2025, the strongest; metals and the dollar in January 2026; the front of the curve only on 26 August 2025.A fall in short yields with long ones steady is also what an expected easing looks like.
Short yields up as much as long ones, dollar up, inflation compensation flat, oil upA repricing of the path of interest rates.September 2026; 28 August 2026; 2013.Leaves room for a rising term premium inside the same move.

It persists after the person leaves or the act is reversedDamage to the institution.The United States, 1979 to 1986; the United Kingdom in October 2022; Turkey.Persistence has many causes, including whatever prompted the act.

A simple sign test follows. A loss of trust in a person should push long yields up and the dollar down. That holds on 21 April 2025, briefly in July 2025 and January 2026, weakly on 26 August 2025, and fails in September and October 2026, when the dollar rose.

What cuts against it

The open problem

A chair’s speech can lift the 2-year yield because it tells the market what the path of policy will be, which a model could also predict, with no change in trust at all. Separating information from the person and trust in the person is the identification problem that runs through all of this evidence. None of the 46 scholarly sources read for the thread measures trust in a named person directly, and no formal study of the 2025 and 2026 episodes was found. Intraday data for Treasuries, gold and the dollar around the key dates would lift the best recent cases from B to A. It needs paid data or a researcher with access.

In Holagram’s terms

A market is an ecology. It is a network of agents, human and synthetic, and what they share: prices, rules, news and one another. Each participant perceives the market as a whole of its own: a trader’s sense of the room, a committee’s view of the economy, a model’s view made of the data it was given. None of these is a piece of a market-wide view that a better-placed agent could complete. A price is not one of them, and not their sum. Each order says what one agent will do at what price, and a price is what the meeting of orders leaves.

An office’s word is a gram that many others draw their own against. When a central bank chair or a finance minister speaks, the statement is a gram of how that office perceives the economy and what it will do, offered to be met. A market follows an office when its gram is the one most others are drawn against. Two things give a gram that standing. One is ability: on the Mandates page a mandate is an institution’s ability to take the next step, and a statement carries weight when it binds that step. The other is the record that the office does what its gram says. The evidence splits along the same line. Where the office’s ability to say no was visibly held by others, by courts in the removal of a governor or by a committee vote on rates, prices barely moved, or moved and came back. Where it was not, as with a governor removed by decree, the move was large and it lasted.

The answer comes in milliseconds. Principle 5 on the Hola page asks that a hola be offered to someone who can answer it. A market answers an office’s gram within milliseconds, in public and in numbers, and the answer is itself a gram, drawn from where the market stands. Then a story arrives, that trust was lost. The story is a commentator’s gram of the price move, and it should be answered in turn. The signature table above is that answer, at another distance, and for the autumn of 2026 it points away from the story more than towards it.

Say where you stand. One person is met at several distances: a remark, a voice, an office, an institution, a currency area. The studies of tone and face are about the voice, the studies of governor turnover about the institution, and the episodes of April 2025 and January 2026 about the office. Principle 1 asks that the distance be said. A fall after a person speaks is not yet a verdict on the person.

People and models. A model of how a central bank reacts is a model of an office and a committee, and its parameters stand for what the people in them will do. Such models fail when those people change how they act (Lucas 1976). People matter most when they are the parameters, and models matter as the shared language in which people read one another. A model that leaves the person out will misprice the first minutes, and a story that leaves the institution out will misread the next years.

The felt reading. The market reads a chair’s tone of voice and facial expression, beyond the words and the decision, with effects that are small and brief. That is judgement from where a person sits, made in seconds and checked against everyone else’s. It is a real reading, since it moves prices, and like any reading it is there to be answered.

Whose gram. Machine readers are agents whose holas were made from how people reacted to offices, so they inherit the office as the anchor. What changes is provenance. A gram says whose it is. A hijacked news account in 2013, an invented picture in 2023, a hijacked regulator’s account in 2024 and a false relay of what the president would decide in 2025 each moved prices for minutes, because each carried a “whose” that was not its own, and the market met it as if it were the office’s.

How the thread was put together

Five AI scouts searched in parallel: US episodes from January 2025 to October 2026, US history from 1955, episodes outside the United States, the scholarly literature with its counter-evidence, and voice, provenance and machine readers. They collected 58 cases and counter-cases, 46 scholarly sources and 8 entries on machine reading, and marked each figure by whether it was read on a page or only in a search result. Three AI auditors then re-checked 85 entries on pages they opened themselves. Of 383 claims, 310 were confirmed, 53 needed a correction, 5 were wrong and 15 could not be verified; there were no errors of sign or unit. The corrections are carried into this page. The US Treasury’s own closing yields were read directly for the key windows, and they match the scouts’ figures wherever the two overlap.

The weaker spots: several news pages could be read only through reprints, a few historical index closes rest on search results, and the scouts’ search allowance ran out, so later checks were made by opening pages only. The text of this page was drafted by a language model from that evidence and published on a person’s decision, which follows the rule on the Research page: models draft and object, and say so; a person decides.

A fourth method proposal on credibility, read like Cities, Strategy making and Mandates, is possible and is not made here.

The watch, written in advance

The finding can be tested forward. Three dated checkpoints fall in November 2026: the Treasury’s quarterly refunding announcement on 4 November, a closed White House hearing on 5 November on the removal of a Fed governor, and the deadline of 10 November for the governor’s final written statement. The signatures that would show trust or interest rates as the driver are written down before the events, with the rules for reading them afterwards.
