Day in the Life of a Fixed Income Trader: Rates, Credit and Mortgages

A US Treasury trader in New York does not start the day. They inherit it. The global trading day for Treasuries opens in Tokyo at 8:30 in the morning local time, which is 7:30 the previous evening in New York, passes to London in the small hours, and reaches New York at about 7:30am. By then the book has already traded in two cities.

What happens next depends on the desk. A rates junior's morning turns on a scheduled number, a securitized junior's on a settlement calendar, and a credit junior's on the runs and axes that bring client orders in. Here is the day on all three, hour by hour, with the words the floor uses without explaining them and the hours as the people who work them describe them.

A bond desk's day starts in another city

The clearest map of that handoff comes from a 1997 New York Fed study of round-the-clock Treasury trading. Tokyo trades until roughly 4pm local time, 3am in New York, when trading passes to London, where it is 8am. At about 12:30pm in London, trading passes to New York, where it is 7:30am, and New York trades on until about 5:30pm. The study gives those times in New York daylight time, and the mechanism is structural: the book follows the sun.

The hours overlap at the edges. Traders in London keep dealing through their afternoon while the New York morning picks up, and that overlap shapes a London desk's whole day. A rates salesperson profiled on Morgan Stanley's careers site, who started on a London desk before moving to New York, describes the London version plainly:

"As a salesperson in London, you get in at 6:30 or 7:00 in the morning when it's the afternoon in Asia, and then you overlap with New York for the rest of the trading session, so it's a global team covering the same client base 24/7."

For a New York desk the handoff runs the other way. The junior arrives to overnight levels set in Tokyo and London, and the first job is to check that the book looks the way it should before New York's own flow begins.

In the 1994 sample the New York Fed study measured, more than 94 percent of Treasury volume traded during New York hours, under 4 percent in London and under 2 percent in Tokyo. The overnight sessions were thin, and the weight of the day sat in New York.

Three desks, one day, side by side

Put the three desks next to each other and the shape of the day is the same: prices checked before the flow starts, a meeting, a burst of client business, then reconciliation, the P&L and the hedge. What sets the pace differs. The rows below are phases of the day in New York time rather than fixed times, because no two desks keep quite the same clock.

The securitized column follows one mortgage trader's account of their own desk, and the credit column keeps to the shape every flow desk shares. None of the rows is a time anyone clocks in.

Six words the desk uses and nobody explains

Much of the vocabulary in that table is never defined for a new joiner. It turns up in the first morning meeting and everyone assumes it is known. These six carry most of the day.

The axe is the one to learn first. A run shows where the desk would trade; an axe says the desk wants to. A salesperson who knows the desk's axes knows which clients to call before the flow starts, which is why axes come up in the morning meeting rather than after it.

Before the open: overnight moves, runs and the morning meeting

The first hour is the same job on every desk: find out what moved while you were away and make sure the desk's prices reflect it. On the rates desk that means checking overnight levels in London and Tokyo, loading the swap pricer and confirming the curve looks right against yesterday's close.

Then the runs. A junior refreshes the prices the desk will show clients, across every bond or coupon it quotes, so the first client call of the day gets a number that reflects the overnight move rather than yesterday's. On the securitized desk those pricing runs cover every actively traded coupon and program, and prepayment reports get checked alongside them.

The morning meeting follows. On a rates desk it brings sales and research together to set the tone before the desk opens in earnest. On the mortgage desk it is a risk meeting first, then a meeting with sales to go through the axes and the bids and offers expected that day. By the time it ends, a junior should have four things ready:

• Overnight moves, checked against the desk's closing levels
• Runs refreshed across the bonds or coupons the desk quotes
• The day's calendar: data releases, auctions and settlement dates
• The desk's axes, so sales knows what to show clients

The rates desk: a day built around one number

The rates desk trades the government bond curve and everything priced off it, and its day is organised around a small number of scheduled moments rather than a constant stream. Whatever the day's number is, a jobs report, a Treasury auction or a Federal Reserve decision, that is when the real work starts.

The jobs report sets the most familiar clock. The Bureau of Labor Statistics releases the Employment Situation at 8:30am Eastern, almost always on the first Friday of the month. The Federal Reserve's rate-setting committee meets on a published calendar, eight times in 2026, and announces its decision on the second day of each meeting.

When the number lands, client orders arrive in a burst. Hedges get executed in Treasury futures, and the junior is booking trades and updating the blotter in real time rather than reading about markets. The junior's job in that burst is accuracy, not opinion: every trade booked right, as it happens.

The afternoon slows into position reconciliation, an end-of-day report and a hedge check before the desk hands off to the next region.

The credit desk: runs, axes and the tape

The credit desk's day has the same frame as the others: overnight moves checked, a morning meeting with sales, client flow through the day and a P&L at the close. What gives it its own texture is the tape. Corporate bond trades have to be reported to FINRA's TRACE system, whose standard hours run from 8:00am to 6:29:59pm Eastern, so the prints of what actually traded, and at what price, are there to watch all day.

For a junior that makes the tape part of the job. The prints show where bonds the desk quotes have actually traded, which is the running check on whether the desk's run is still right.

The credit floor is also more than one seat. The investment grade flow desk is covered on the credit trading page, and high yield, distressed debt and CLO trading each sit on desks of their own, with their own version of the day.

The securitized desk: one mortgage trader's day

The most detailed account of a full day comes from a mortgage trader several years into the job, working in residential mortgage-backed securities, who answered a forum question about fixed income trading with a list. It describes one seat on the securitized products desk, and here it is as they gave it:

1. Wake up and check Bloomberg for the curve, swaps, TBAs, equities and anything else moving markets.
2. A morning risk meeting, then a meeting with sales on axes and upcoming bids and offers.
3. Trade analysis prepared for sales and client discussions.
4. A check-in with senior traders to see whether they need help with anything.
5. Coordination with middle office, controls, risk and the analytics teams on new positions.
6. Spreadsheet work and internal pricing systems, which they called busy work.
7. Before the close, the P&L calculated and circulated to the desk.
8. The book confirmed as properly hedged, loose ends tied up, and out around 6 to 7pm.

Two things in it are specific to mortgages. The day runs on the TBA settlement calendar: SIFMA's good delivery rules require pool notification 48 hours before settlement, so pricing runs and the allocation of pools to trades have to clear ahead of that deadline on every settlement date, whatever the market is doing.

And new positions involve the wider building, which is why middle office, controls, risk and the analytics teams appear on a trader's to-do list at all.

The afternoon, the close and the P&L explain

After the morning's burst, the afternoon is where a junior's accuracy gets tested. Positions get reconciled against what was actually booked, the end-of-day report gets written, and on the mortgage desk the P&L is calculated and circulated before the close.

The P&L explain is what turns that number into an account of the day: not one figure, but the figure broken into the rate moves, spread moves, new trades and carry that produced it. It is also where the day's bookings get checked a second time, because a trade booked wrong shows up as P&L nobody can explain.

Then the hedge. Before anyone leaves, the book has to be where it should be: the rates desk runs a hedge check before handing off to the next region, and the mortgage trader's list ends with making sure the desk is properly hedged. Around all of it sits the risk limit, the cap on the exposure a trader or desk may hold. Breaching one is not a judgment call: it gets escalated.

None of this is visible from outside, and it is most of what the first years behind a fixed income trader's pay actually consist of: booking trades correctly, reconciling positions after the market closes, and building the spreadsheets senior traders use to price and hedge.

What the junior does, and what the senior does

The split is less about hours than about what each person owns. A junior owns the accuracy of the book: the prices, the bookings, the reconciliation and the report. A senior owns the risk in it. The route from one to the other runs through the plumbing: a junior who is good at it earns trust before earning any real risk to run, and trust is what eventually turns into a book.

The junior's day

• Checks overnight levels and loads the pricer
• Refreshes the runs across every bond or coupon the desk quotes
• Books trades and updates the blotter as the flow arrives
• Reconciles positions, writes the end-of-day report, checks the hedge

The senior's day

• Runs the book and the risk in it
• Prices and hedges on the spreadsheets the junior keeps
• Talks a client order through in real time
• Earned the book by doing the junior job well first

The mortgage trader's list shows the relationship from the junior side: one line of it is simply checking in with the seniors to see whether they need help with anything. Juniors also sit close enough to hear how a market maker talks a client order through in real time, which is where the glossary above starts to mean something.

When the calendar changes the day

A desk's routine is the default. The calendar overrides it, and four kinds of day are worth knowing:

• Data-release days. The jobs report at 8:30am Eastern compresses a rates desk's morning: whatever preparation the desk does has to be finished before the number, because the orders arrive in a burst after it.
• Event days. A Treasury auction or a Federal Reserve decision on the second day of a meeting is on the calendar before it happens, so the desk plans around it rather than reacting. A new-issue day belongs in the same family: an event the desk knows is coming.
• Settlement days. On the securitized desk, pool notification 48 hours before each TBA settlement is a deadline that does not move for the market.
• Short days. SIFMA recommends a 2:00pm Eastern close the day before Independence Day, the day after Thanksgiving, Christmas Eve and New Year's Eve, and a noon close on Good Friday.

SIFMA's recommendations are not legally binding, but they are widely adopted, and they reach across government securities, mortgage and asset-backed securities, investment grade and high yield corporate bonds and municipal bonds. On a short day the afternoon's reconciliation and hedge check simply happen earlier.

The common thread is that the calendar, not the clock, sets the pace. A junior who knows the calendar knows which mornings will be quiet and which will not.

How long the day actually is

Nobody publishes a standard day, and the banks say as much. HSBC's trading careers page warns that markets are unpredictable and that hours and workload vary with the products and markets being traded: the area "isn't recommended for someone looking for a consistent 9-5." J.P. Morgan's markets analyst page says the day-to-day will vary with the team and with what is going on in the markets.

The accounts from the desk give ranges, not rules. The Morgan Stanley rates salesperson describes the London day as early in and early out: "I start early but I finish early. I rarely work past 7 pm... It's a very compact, intense day, and then you get to go home and have your weekends off."

On the mortgage desk, juniors leave around 6 to 7pm. On the same desk, that trader has seen mid-level and senior people get in at 9 and leave at 4. Their summary of the job was blunt: the hours are not brutal, and the pay is very attractive for the work people put in.

What moves the hours is mostly structural: which city the desk sits in relative to the market it trades, how heavy the calendar is, and how senior the person is.

What the job is not

The film version of a bond desk is a pit of people shouting prices at each other. The US bond market does not work like that. It trades over the counter, dealer to client, not in an exchange pit, and the parts that once ran by voice have moved heavily onto screens.

The share of dealer-to-client Treasury volume traded electronically rose from 46 percent in May 2019 to 63 percent in May 2024. TBA contracts, the most liquid thing on the securitized desk, trade predominantly electronically.

The accounts of the day read nothing like the film. Goldman Sachs's own published day inside its Global Markets division, in its Structured Finance Investing and Lending business, is coffee, email and catching up with colleagues in the morning, then client and syndication-partner calls and an internal committee meeting in the afternoon, and project work in the evening.

The mortgage trader's day is Bloomberg screens, a risk meeting, spreadsheets and pricing systems. The Morgan Stanley salesperson calls her day compact and intense, and rarely works past 7pm.

The real pressure of the job is quieter: a booking that has to be right in the busiest minutes of the day, a P&L that has to be explained before anyone goes home, and a hedge that has to be in place before the book passes to another city.

Where the sales seat fits

Every desk above works with sales, and the sales seat has a day of its own, covered in full on the fixed income sales page. In brief, the salesperson holds the client relationship and carries the desk's runs and axes to the clients who might want them. The Morgan Stanley salesperson's desk traded government bonds and hedged interest rate exposure for macro hedge fund clients, and in London the day started in Asia's afternoon.

What the big dealers publish about the day leans the same way. Goldman's published day puts the client-facing version in one line: "I spend my days focused on building strong relationships with our institutional clients."

For someone aiming at a trading seat, that makes the careers pages a better guide to the sales day than to the trading one. The trading day is better read from the desk pages themselves, each of which describes its own junior's day: rates, credit and securitized products.

The first year, and what juniors wish they had known

The banks do not pretend the first year is gentle. HSBC's trading careers page encourages applicants from all backgrounds but warns that the learning curve is steep, so a real interest in the area is important.

What fills that year is the work described above: runs, bookings, reconciliations, reports and the hedge check, done accurately enough that the seniors trust the numbers. The mortgage trader's list is, in effect, a first-year job description written by someone past it. The internship route in is covered with its recruiting cycle on the sales and trading internship page.

In the same forum thread, the traders' advice to people weighing the seat came back to four things:

• Automation. The mortgage trader's view was that spreads are wider in fixed income and that it is being automated much more slowly than equities.
• Hours. Unlike equities, they said, there are no defined market hours, at least in residential mortgages.
• Exits. They counted limited exit opportunities, compared with equities or banking, as the trade-off; the routes that do exist are mapped in fixed income exit opportunities.
• Company. A first-year on an agency mortgage desk said few juniors seemed to want a career on a flow desk, and that they were by far the youngest on their own.

Whether that trade-off is worth making is the why fixed income question, and it is worth answering before the first 6:30am start rather than after it.

The bottom line

A fixed income trader's day is not one day. The rates desk's turns on a scheduled number, the securitized desk's on a settlement calendar, and the credit desk's on runs, axes and the tape. What they share is a shape: prices checked before the flow, a meeting, the burst, then the reconciliation, the P&L explain and the hedge before the book moves on.

For a junior, that shape is the job. It is accurate, repetitive and mostly invisible, and it is how a junior earns the trust that turns into a book. The hours around it depend on the city, the calendar and the seat, which is why anyone quoting a single number for them is describing their own desk.
