Nobody Regulates When a Trader Has to Wake Up

Air traffic controllers can’t legally work a solo overnight shift anymore. Nuclear plant operators are capped at 16 hours in any 24. Truckers log hours electronically because a paper logbook used to be too easy to falsify. Each of those limits exists because a regulator decided a tired person in that job could hurt someone who wasn’t in the room and had no say in the risk.

A futures trader running on four hours of sleep, about to route eight-figure orders through a market that opens in eleven minutes, answers to none of that. No agency caps a trading desk’s hours. No log gets audited for rest violations. One of the highest-stakes jobs in the country, measured in dollars moved per waking hour, runs its wake-up schedule on pay, seniority, and the fear of being the one desk that showed up late. Something similar, on a far smaller scale, drives resellers staging an overnight setup for a 3 a.m. sneaker release: showing up late costs money either way, just a different kind.

The schedule, and why it starts before the market does

U.S. equity markets open at 9:30 a.m. Eastern, but very little of a trading floor’s actual workday starts there. Index futures trade nearly around the clock, and European exchanges are already active while most of the East Coast is still asleep, so a trader responsible for overnight risk or pre-market positioning is often at a desk by 4 a.m., earlier still on macro and rates desks tracking Asian markets that never fully closed. Equity traders without an overnight book still arrive by 6:30 or 7, well ahead of the opening bell, to read overnight news and position before the first print. This isn’t written down anywhere as a requirement. It’s simply what the job pays for, and what skipping it costs against everyone else at the firm who didn’t skip it. It’s also a human clock, not a natural one, which puts it in a different category from the handful of jobs where a furnace, a tide, or a vat of milk sets the hour instead: an exchange’s open time is a decision a committee made and could, in principle, unmake, where nobody has ever successfully lobbied a tide to move.

Junior staff feel the same clock from the other end. Long-hours culture on trading floors and in the analyst programs that feed them has been reported on for decades, but it became impossible to wave off as folklore in 2013, when Bank of America Merrill Lynch’s London office lost a 21-year-old intern, Moritz Erhardt, after a stretch of reported 72-hour work cycles; the bank commissioned an internal review and several major banks introduced junior-analyst hour caps afterward. Those caps addressed total weekly hours. None addressed the specific 4 a.m. start, because nothing about the market’s own open time changed.

What happens to decision quality when that schedule runs on too little sleep

John Coates traded for thirteen years at Goldman Sachs and Deutsche Bank before retraining as a neuroscientist at Cambridge, largely because he’d watched physiology, not analysis, move a trading floor. His research on cortisol found levels among City of London traders rising 68 percent during a sustained volatile stretch, and when his team raised cortisol artificially in volunteers by a comparable amount, measured risk appetite dropped by a similar margin. Chronic sleep loss feeds the same hormonal pathway from a different direction: short sleep elevates the stress hormones that, past a certain point, push risk-taking into erratic territory rather than merely reducing it evenly.

Research tracking real trading and investing behavior, separate from Coates’s physiology work, has found that under-slept traders are measurably more likely to trade impulsively right after news breaks, not because they react faster but because they miss the fuller picture, and more likely to reach for long-shot, asymmetric bets over balanced ones. The pathway runs through the prefrontal cortex losing relative influence over the amygdala under sleep restriction, a well-established finding outside finance too. Sleep loss’s effect on financial decisions is its own well-studied territory even for an ordinary person managing a household budget; a professional desk just multiplies the size and speed of every decision that pattern touches.

Why hasn’t any of this been regulated the way flying or trucking has

Because the failure modes genuinely don’t resemble each other. A fatigued pilot’s mistake is immediate, physical, and forced onto passengers who never chose that flight crew. A fatigued trader’s mistake shows up as a slightly worse return over a stretch of weeks, gets absorbed inside the firm’s own capital before it reaches anyone outside the building, and is nearly impossible to trace to one under-slept morning after the fact. There’s no equivalent of a plane going down. There’s a number that’s quietly worse than it would have been, in a ledger nobody outside the firm ever audits for that cause.

What fills the gap where a rule would otherwise be is compensation, seniority, and a floor’s own visible culture of who was already at their desk when you arrived. That’s a genuine incentive, arguably a stronger one hour-for-hour than a federal rule would be, but it rewards a different outcome than a rest requirement would. It rewards being present and awake-looking, not necessarily being at your sharpest. Sleeping eight hours to be clearer at 9:30 earns no visible credit at all, and in a culture built around who was seen first, can even read as not caring enough about the job.

What happened the one time junior staff got loud about it

In February 2021, a group of first-year Goldman Sachs analysts built their own internal survey and presented it to management: roughly 95-hour work weeks, about five hours of sleep a night, and a majority reporting they’d considered or sought help for the toll it was taking. Goldman already had a written “Saturday rule” on the books, staff meant to be out of the office from 9 p.m. Friday to 9 a.m. Sunday except in genuine emergencies, and the analysts’ own account was that the rule existed on paper and got routinely waived in practice, since asking a manager for the required exception was the kind of request a first-year worried would read as not being a team player. CEO David Solomon’s public response promised stricter enforcement of the existing rule and faster junior hiring to spread the load. Notably absent from that response: anything about the 4 a.m. starts on the trading and capital-markets side of the business, which the survey wasn’t really about in the first place. Analyst hours and a trader’s clock are adjacent problems, and only one of them got a headline-grabbing fix.

The same problem, worse, on the other side of the world

New York’s 4 a.m. start looks almost gentle next to how Hong Kong and Singapore trading floors have historically run. A trading day there already opens well before New York’s overnight desks wind down, and long-hours culture in Asian financial centers has drawn its own rounds of press scrutiny and, at points, regulatory attention to overwork, without producing a rest-hour rule any more binding than New York’s. A global bank running both a Hong Kong equities desk and a New York rates desk effectively has traders somewhere in its organization awake and pricing risk at nearly every hour of every day, coordinated across time zones by nothing more formal than handoff calls and shared spreadsheets. No single regulator sees the whole picture, because no single regulator has jurisdiction over the whole picture.

Would traders even want a rule like this

Economists have a term for part of the answer: a compensating wage differential, the extra pay a job offers to make up for a genuinely bad condition attached to it, the way offshore oil workers or long-haul pilots are paid more partly for the schedule itself. Wall Street compensation is famously steep at the top, and part of what it’s steep for is the hours, not despite them. A trader who resents the 4 a.m. start has an exit: quit and take a job with normal hours for meaningfully less money. Very few take it, which an economist would read as the market having already priced the schedule into the paycheck, and a regulator would read as exactly why nobody outside the industry has pushed hard for a rule the workers themselves haven’t organized to demand.

That’s a real answer, but not a complete one. The revealed preference of someone who stays in a 4 a.m. job assumes the person deciding is making that trade with clear judgment, which is precisely what chronic sleep restriction degrades over time. A tired decision to keep making tired decisions isn’t proof the arrangement is fine; it’s the same cortisol and prefrontal-cortex pattern from earlier in this piece, just applied to a career choice instead of a single day’s trade.

Crypto removed even the one boundary equities still have

Everything above assumes a market that closes. Equities still shut down at 4 p.m. and reopen the next morning, which at least gives a trader a defined night. Crypto markets don’t close, ever, on any day of the week, and a desk trading digital assets has no 4:30 a.m. start because there’s no 9:30 a.m. open to prepare for; the market has been live the entire time the trader was asleep. Firms handle this with rotating shifts rather than one person on permanently, but the rotation itself runs on the same internal, unregulated basis as everything else here. If equities and futures represent an unregulated early start, always-on markets are the same absence of a rule taken to its logical end: no market close means no natural point where a regulator, or anyone else, could even propose a rest requirement tied to the trading day, because there is no longer a trading day to tie one to.

Is there a version of external accountability that would help here

Probably not one imposed from outside the firm. Banks have tried wellness stipends, mandated vacation weeks (partly a fraud-detection measure disguised as a rest measure, since an employee who never takes leave has more opportunity to hide problems in their own book), and, after Erhardt’s death and similar cases, hard weekly-hour caps for junior staff. Every one of those addresses total hours worked. None of them touches the 4 a.m. start itself, because nothing about a market’s own open time is negotiable the way an internal policy is.

The real contrast with the professions that do have a federal rule isn’t that trading needs an FAA-style limit too. It’s that the jobs that already have one all share a visible, third-party victim when the tired person gets it wrong. A trading floor’s victim is diffuse, delayed, and internal to the firm’s own balance sheet, and regulators have consistently treated that as a different category of harm from a plane, a reactor, or a ship. Whether that distinction survives a bad enough quarter is a separate question from whether it holds today. Today, it plainly does.

The tools this blog usually covers, a friend confirming you’re awake, a witness with something small at stake, weren’t built for a trading floor’s hours or its kind of risk. DontSnooze solves an ordinary person’s ordinary alarm problem and has nothing useful to say about cortisol, risk appetite, or a 3:30 a.m. futures desk. Worth being plain about the limits of a free social accountability app when the job on the other side of the wake-up is moving other people’s money.
