1. 066What is an ISDA Master Agreement and what does the CSA do?Market structure and clearingIntermediatetechnicalDerivatives operationsRisk management

   Say this

   The ISDA Master is the contract that governs all trades between two counterparties, so each new deal is a short confirmation under one legal framework rather than a fresh negotiation. Its most important function is close-out netting: on a default, all trades collapse into a single net amount. The Credit Support Annex is the collateral schedule bolted onto it — what you post, when, in what form, and with what thresholds.

   Then walk it

   1. Structure: the Master Agreement, a Schedule with the negotiated elections, definitions booklets by asset class, the CSA for collateral, and then individual trade confirmations. The confirmation for a swap can be a page because everything else is upstairs.
   2. Close-out netting is the commercial heart of it. Without it, a defaulting counterparty's administrator could cherry-pick — enforce the trades in their favour and disclaim the rest. Netting is why gross notional figures overstate real exposure by an order of magnitude, and why the enforceability opinion in each jurisdiction matters so much.
   3. Events of default and termination events are the other core: failure to pay, bankruptcy, cross-default, and negotiated ones like a ratings downgrade trigger or a NAV decline clause for a fund.
   4. The CSA sets the collateral mechanics: threshold, which is the unsecured amount you tolerate before any collateral moves; minimum transfer amount, to avoid moving trivial sums; eligible collateral and haircuts; and the valuation and dispute process.
   5. Those parameters are a real negotiation, not boilerplate. A high threshold means less operational friction and more credit exposure. Asymmetric thresholds, where the weaker credit posts and the dealer does not, were standard before the crisis and are much rarer now.
   6. India-specific note: the enforceability of close-out netting was genuinely uncertain here until the Bilateral Netting of Qualified Financial Contracts Act 2020, which is why bilateral derivative activity with Indian counterparties was constrained and priced accordingly. That legislation is one reason the onshore OTC market has been able to develop.

   Where candidates lose it

   Calling the ISDA Master 'the derivatives contract' without naming close-out netting. Netting is the reason the document exists and the reason gross notional is a misleading number. For an India-facing interview, knowing the 2020 netting legislation is a genuine differentiator.

   Expect next

   • Why is close-out netting so important to a dealer's capital?
   • What is the difference between a threshold and a minimum transfer amount?
   • How did the Indian netting legislation change the market here?
2. 068What does prime brokerage do, and how does it connect to the derivatives business?Market structure and clearingIntermediatetechnicalMSMorgan StanleyGlobal Markets · London · 2024

   Say this

   Prime brokerage is the outsourced back and middle office for a hedge fund, plus the financing. It provides custody, clearing, consolidated reporting, margin lending, stock borrow for shorting, and synthetic exposure through swaps. It connects to derivatives because the synthetic financing business — total return swaps and portfolio swaps — is where much of the balance sheet and much of the revenue now sits.

   Then walk it

   1. The core services: execution and clearing across brokers, custody of assets, one consolidated report of positions and profit and loss, cash management, and capital introduction to help the fund raise money.
   2. The revenue is mostly financing. Margin lending on the long book, the spread on stock borrow for the short book, and fees on the synthetic side. Rebate on short sale proceeds is a bigger line than most people expect.
   3. Synthetic prime is the derivatives link. Instead of the fund buying the stock and borrowing money, the prime broker holds the stock and writes a total return swap to the fund. The fund gets the economics, the broker keeps the position and charges a financing spread. It is more capital-efficient for the fund and often cheaper than cash prime.
   4. That structure also has consequences the industry learned about the hard way. Synthetic positions are not disclosed as ownership in most jurisdictions, and because each broker sees only its own slice, a client can build enormous concentrated leverage across several primes. That is exactly what Archegos did in 2021, and it cost Credit Suisse over 5 billion dollars.
   5. The risk management question for the broker is margin methodology on a concentrated, illiquid book — and whether you have the client's full picture. A dynamic margin model that accounts for concentration and liquidation horizon is the difference between a profitable business and Archegos.
   6. For the fund, counterparty risk cuts the other way, which is the Lehman lesson: assets that were rehypothecated in the UK entity were part of the insolvency estate, and funds lost access for years. Which is why serious funds now run multiple primes, negotiate rehypothecation limits, and monitor where their assets actually sit.

   Where candidates lose it

   Reciting a service list. A Global Markets interviewer wants to hear where the money is — financing, not execution — and how synthetic prime uses derivatives. Naming Archegos on the broker's side and Lehman on the fund's side turns a description into an understanding of the risk.

   Expect next

   • Where does a prime broker actually make its money?
   • What is synthetic prime and why do funds use it?
   • What went wrong in the Archegos episode?

3. 069What makes the Indian index options market different from other major markets?Indian derivativesIntermediatetechnicalIndian derivatives desksIndian broking

   Say this

   Scale and concentration. By contract count India has been the largest derivatives market in the world for several years, and almost all of it is short-dated index options — Nifty and Bank Nifty weeklies — traded by a very large retail base. The premium turnover is a fraction of the notional, so the volume statistics flatter it enormously.

   Then walk it

   1. Structure: all index options are European and cash-settled on a weighted average price of the last half hour, which removes assignment and delivery mechanics entirely and makes the product very easy for retail to access.
   2. Lot sizes are set in notional terms and periodically revised, and SEBI raised them substantially in late 2024 specifically to make the minimum ticket larger and less accessible to small accounts.
   3. The expiry calendar is the defining feature. A weekly expiry means enormous gamma and theta concentration in the final days, and a very large share of total volume happens on expiry day itself in options that are almost entirely time value.
   4. Single stock derivatives exist but are a much smaller share, and they are physically settled since 2018 — which changed behaviour, because a retail trader holding an in-the-money single stock option now faces delivery obligations and much larger margins into expiry.
   5. Participants: proprietary and algorithmic firms dominate the profitable side, foreign portfolio investors and domestic institutions use index futures and options for hedging, and retail is overwhelmingly on the option-selling and cheap-option-buying side. The Jane Street enforcement matter in 2025 made the size of the prop share very public.
   6. The honest read: the volume numbers are not comparable to US or European markets, because a 50 rupee out-of-the-money Nifty option is one contract in the statistics and nearly no risk transfer. Premium turnover, not contract count, is the number to quote if you want to sound like you know the market rather than the headline.

   Where candidates lose it

   Quoting 'India is the world's largest derivatives market' as though it settles the matter. The comparison is by contract count, dominated by cheap weekly options, and premium turnover tells a different story. Making that distinction unprompted is the single best signal you understand this market.

   Expect next

   • Why is contract count a misleading comparison?
   • What changed when single stock derivatives moved to physical settlement?
   • Who is actually making money in this market?
4. 070Explain the weekly expiry ecosystem in Indian index options and what it does to pricing.Indian derivativesIntermediatetechnicalIndian derivatives desksIndian broking

   Say this

   Weekly expiries created a market where most of the volume is in options with one to four days of life, which means enormous gamma and theta and almost no vega. Pricing on expiry day stops looking like Black-Scholes and starts looking like a supply and demand auction on a few strikes around spot, with implied volatility on the wings that no model would produce.

   Then walk it

   1. The mechanics: exchanges staggered weekly expiries across indices so that at one point there was an expiry nearly every day of the week, which concentrated retail activity into a daily cycle rather than a monthly one. SEBI cut this back to one weekly expiry per exchange in late 2024.
   2. What short dating does to the Greeks: a one-day at-the-money option has enormous gamma and theta and essentially no vega. So the trade is a pure gamma-versus-theta contest, and the volatility surface becomes almost meaningless as a level.
   3. The observable distortion: far out-of-the-money weekly options trade at implied volatilities of 60, 80, sometimes over 100 percent, not because anyone forecasts that volatility but because the option costs 2 rupees and there is a floor on the tick. Lottery demand sets the price of the wings.
   4. On expiry day the flow dominates. Large short-gamma positions must hedge in the direction of the move, so you get sharp intraday trends into the close, and then a pin towards the strike with the biggest open interest. That is dealer hedging mechanics, not information.
   5. The settlement convention interacts with it: because settlement is a VWAP of the last half hour, hedging demand is concentrated in that window, which is where you see the volume spike and the sharpest moves.
   6. The commercial honesty: this ecosystem exists because it generates extraordinary exchange and broker revenue and because retail demand for lottery payoffs is real. SEBI's own analysis found the large majority of individual derivative traders lose money, and the reforms since 2024 — fewer expiries, larger lots, higher margins near expiry — are a direct response. Anyone interviewing on an Indian desk should be able to say both that the ecosystem is a genuine liquidity pool and that its retail side is a wealth transfer.

   Where candidates lose it

   Describing weekly expiries as just a shorter-dated option. The interviewer wants the consequences: gamma and theta dominate, vega vanishes, wing implied volatilities become meaningless, and expiry-day price action is dealer hedging rather than information. And be able to state the retail loss data without editorialising.

   Expect next

   • Why do far out-of-the-money weeklies show implied volatilities over 80 percent?
   • What causes the sharp moves in the last half hour of expiry day?
   • What did SEBI change in 2024 and why?
5. 073How do currency derivatives work on the Indian exchanges, and what are the constraints?Indian derivativesIntermediatetechnicalIndian derivatives desksFX derivatives

   Say this

   Exchange-traded currency futures and options on USD/INR and a few crosses, cash-settled in rupees against the RBI reference rate, with small lot sizes — a thousand dollars per futures lot. The defining constraint is that use is tied to having an underlying exposure: the RBI tightened enforcement of that in 2023 and effectively ended the speculative retail segment.

   Then walk it

   1. Products: USD/INR futures and options are by far the most liquid, plus EUR/INR, GBP/INR and JPY/INR futures with thin volumes, and cross-currency pairs like EUR/USD listed in rupee terms.
   2. Settlement is cash against the RBI reference rate on the expiry date, so there is no delivery of dollars. That makes it accessible but also means the contract is a proxy for, rather than a claim on, the spot market.
   3. Position limits are specific: a client-level cap on USD/INR positions, with larger limits only against demonstrated underlying exposure. The April 2023 clarification requiring participants to have a contracted exposure — and brokers to obtain that declaration — collapsed exchange volumes by a large multiple almost overnight.
   4. So the onshore exchange market is now mostly a hedging venue, and price discovery in the rupee happens elsewhere: the interbank OTC market onshore, and the non-deliverable forward market offshore in Singapore, London and Dubai.
   5. That NDF market is the thing to understand. It exists because the rupee is not fully convertible, it trades outside RBI jurisdiction, and it has repeatedly led onshore pricing during stress. The RBI's response was to let onshore banks participate in the NDF market from 2020, and to build the GIFT City IFSC as an onshore-offshore venue where rupee derivatives trade in dollars.
   6. The honest read on the market: it is small relative to India's trade flows because the regulatory framework prioritises controlling speculation over depth. That is a defensible policy choice — it limits the currency crisis channel — but it means a corporate hedging rupee exposure gets worse liquidity beyond a year than a comparable exposure in a freely convertible currency, and the difference shows up in the price.

   Where candidates lose it

   Describing the contracts without the exposure requirement and the NDF market. The 2023 underlying-exposure enforcement is the single most important recent fact about this market, and if you cannot explain why price discovery migrated offshore, you have described the plumbing without understanding the market.

   Expect next

   • What is an NDF and why does it exist for the rupee?
   • What changed for exchange volumes in 2023 and why?
   • How does GIFT City fit into this?
6. 074Why does Bank Nifty trade differently from Nifty in the options market?Indian derivativesIntermediatetechnicalIndian derivatives desksIndian broking

   Say this

   Because it is a narrow, highly concentrated sector index rather than a diversified one. Twelve banking names, with the top three carrying most of the weight, so it realises materially higher volatility than Nifty and its implied volatility sits several points above. That volatility difference is why it attracted the most aggressive short-dated option activity.

   Then walk it

   1. Composition: Bank Nifty is a dozen banking stocks with heavy concentration in the largest private banks. Nifty is 50 names across sectors, and financials are already its largest weight — which means the two indices are highly correlated but Bank Nifty is the levered version.
   2. Realised volatility runs perhaps 1.2 to 1.5 times Nifty's, and implied volatility follows, so option premiums are larger in both absolute and percentage terms. For a trader wanting the most movement per rupee of premium, Bank Nifty was the obvious instrument.
   3. It is also more event-driven. Credit policy, asset quality data, results from three or four large banks, and rate expectations all hit the whole index at once. Single-name news in HDFC Bank or ICICI moves the index in a way no single name moves Nifty.
   4. Consequence for the surface: skew is steeper and the term structure is more reactive, because a banking-sector shock is a credit shock and the market prices the left tail accordingly.
   5. The regulatory arc matters here. Bank Nifty weekly options had become the single largest contract in the world by volume, and SEBI's late-2024 rationalisation removed its weekly expiry, leaving the weekly to Nifty on the NSE. Volume redistributed rather than disappeared, but the Bank Nifty weekly ecosystem is gone.
   6. The trading implication I would draw: a Nifty against Bank Nifty relative-volatility trade is a clean expression of a view on whether financial-sector dispersion is going to rise. It is short correlation in one index and long it in the other, and it is a more considered trade than simply buying whichever premium looks cheap.

   Where candidates lose it

   Saying 'Bank Nifty is more volatile' without explaining the concentration mechanism, or missing that its weekly expiry was removed in the 2024 reforms. An Indian desk will assume you have traded it, so being current on the expiry change is the test.

   Expect next

   • How would you trade Nifty volatility against Bank Nifty volatility?
   • What happened to Bank Nifty weekly volumes after the 2024 changes?
   • Why is Bank Nifty skew steeper?
7. 076What does the Indian interest rate derivatives market look like, and why is it smaller than you would expect?Indian derivativesIntermediatetechnicalIndian derivatives desksRates derivatives

   Say this

   The liquid instrument is the overnight indexed swap against MIBOR, used mainly by banks and primary dealers to express rate views and manage their books. Bond futures exist and are thin, and the corporate swap market is small. The reason is that most Indian corporate borrowing is bank credit at a floating benchmark that resets anyway, so the hedging demand a deep swap market needs simply is not there.

   Then walk it

   1. OIS is the core. The overnight rate against MIBOR, liquid out to about five years and genuinely liquid in the one-year and five-year, and it is where the market's rate expectations are actually observable. If you want to know what the market thinks the RBI will do, you read the OIS curve, not the bond curve.
   2. Government bond futures on NSE and BSE exist but have never developed sustained liquidity, despite several relaunches. Banks hedge duration in the cash market instead, partly because the held-to-maturity accounting category removes the need to mark and therefore the need to hedge.
   3. Forward rate agreements and interest rate swaps with corporates happen, but the volumes are modest. Most Indian corporate debt is bank loans at a floating benchmark — previously the base rate or MCLR, now largely external benchmark linked — so companies are already floating and the treasurer's question is whether to fix, which many simply do not.
   4. The market also carries a legacy of caution. The 2008 to 2011 episode where corporates lost heavily on complex currency and rate structures sold by banks, and the resulting litigation and RBI scrutiny, made both boards and banks more conservative about derivative hedging than the economics alone would suggest.
   5. What is developing: RBI has progressively liberalised, allowing more participants into OIS and permitting banks to deal in offshore rupee derivatives, and the retail and non-bank participation frameworks have widened. The shift of benchmarks after LIBOR's end accelerated the use of overnight-indexed conventions.
   6. The honest structural point: a deep rates derivative market needs a liquid, marked, widely held government bond market, and India's is dominated by banks holding to maturity under statutory requirements. Until that holding structure changes, the derivative market will stay a bank-to-bank market rather than a broad hedging venue — which is the real answer to why it is smaller than the size of the economy implies.

   Where candidates lose it

   Assuming the Indian rates market mirrors the US or Europe. The interesting answer identifies the cause — statutory bond holdings, held-to-maturity accounting, and floating-rate bank credit — rather than just noting that volumes are low. Naming OIS against MIBOR as the real expectations curve is the practitioner detail.

   Expect next

   • Why have bond futures repeatedly failed to gain traction here?
   • Where would you read the market's view on the next RBI move?
   • What would have to change for the corporate swap market to grow?
8. 077How do you view the market today?Trading and marketsIntermediatetechnicalMizuhoSales and Trading · New York · 2026

   Say this

   Give a structure, not a survey. I would frame it as: here is what the market is currently pricing, here is where I think that pricing is wrong, and here is the trade. Three levels quoted from memory, one view, one thing that would change my mind.

   Then walk it

   1. Open with the pricing, because that is how a trader talks. Where the policy rate is and how many cuts or hikes the curve has in it over the next year. Where ten-year yields are. Where index implied volatility is against realised. Those three numbers tell the interviewer you look at screens.
   2. Then the regime read in one sentence. Something like: the market is pricing a soft landing with the equity risk premium near its lows and volatility subdued, which means the price of being wrong on growth is unusually high.
   3. Then your actual view, stated as a disagreement. Not 'I am cautious' — rather, 'I think the curve has too many cuts priced for the inflation prints we are getting, so I would be paid at the front end.'
   4. Then the derivatives expression, because this is a derivatives seat. If the view is that realised volatility will exceed the low implied, own gamma. If the view is directional with a date attached, use a spread rather than an outright.
   5. Then the falsifier. One data point or level that would make you abandon the view. This is the part that makes you sound like someone who has run risk rather than read commentary.
   6. And know your own numbers. If you quote a level you must be able to say where it was three months ago and what moved it. A wrong number said confidently is worse than saying 'roughly 4 and a quarter, I have not checked this morning'.

   Where candidates lose it

   Summarising the news. Everyone can say inflation is coming down and the Fed is data-dependent. The answer that gets a callback quotes three levels, names one disagreement with the market's pricing, expresses it as a trade, and says what would falsify it. And never invent a number you cannot defend.

   Expect next

   • So what trade would you put on?
   • Where were those levels three months ago?
   • What would make you change your mind?

9. 078What is the current market sentiment?Trading and marketsIntermediatetechnicalNomuraGlobal Markets · New York · 2026

   Say this

   Answer it with positioning and prices rather than adjectives. Sentiment is observable: where implied volatility sits versus realised, how steep the skew is, what the put-call ratio and futures positioning look like, and how credit spreads are behaving relative to equities. Then say whether sentiment and fundamentals are pointing the same way.

   Then walk it

   1. The measurable sentiment indicators I would name: index implied volatility and its term structure, the skew or 25-delta risk reversal, high yield credit spreads, and CFTC or equivalent positioning data on the major futures.
   2. The most useful single read is often implied versus realised volatility. A low VIX with even lower realised volatility means complacency is cheap; a low VIX against rising realised means the market has not caught up yet.
   3. Then a cross-asset check, because sentiment is only interesting when assets disagree. Equities at highs with credit spreads widening, or gold making highs with real yields also rising, tells you something is unresolved. Consistent moves across assets tell you less.
   4. Then the positioning point, which is where sentiment becomes tradeable: extreme one-sided positioning makes the market fragile to news that would otherwise be minor, because the marginal buyer is already fully invested.
   5. Say it in one line at the end: 'so the market is priced for a benign outcome with low protection demand, which means the payoff to owning tail hedges is better than usual even though nothing is obviously wrong.' That is a sentiment read that ends in a trade.
   6. And the caveat worth volunteering: sentiment is a terrible timing tool. Extremes can persist for quarters, and 'everyone is bullish' has been a losing short signal far more often than a winning one. I would use it for sizing and for hedging cost, not for entry.

   Where candidates lose it

   Answering with a feeling — 'cautiously optimistic', 'risk-on'. On a markets desk, sentiment means observable positioning and prices. Name four indicators, say what they currently show, and finish with what it implies for the cost of protection. Then admit it is not a timing signal.

   Expect next

   • Which single indicator would you rely on most, and why?
   • Where do assets currently disagree with each other?
   • Has extreme positioning ever been a good short signal?

10. 081What is crude trading at right now? And walk me through what has moved it this month.Trading and marketsIntermediatetechnicalRCRBC Capital MarketsSales and Trading · London · 2025

    Say this

    Give the level, name which contract you are quoting, then the two or three drivers with a direction and rough magnitude. And say the curve shape, because on a commodities or macro desk that is half the information.

    Then walk it

    1. Be specific about the instrument. Brent front month versus WTI front month are different numbers with a spread between them, and quoting one when asked about the other is the first mistake. Say 'Brent front month is around X' and give the WTI spread if you know it.
    2. Then the curve: is the front in contango or backwardation and by how much. That tells the interviewer whether inventories are tight, and it is the piece a generalist candidate never has.
    3. Then two or three drivers with direction and size. On the supply side: OPEC+ quota decisions and actual compliance, US shale production, and any outage or sanctions development. On the demand side: Chinese import data, refinery margins, and the growth outlook.
    4. Distinguish flow from fundamentals. A move driven by managed-money positioning unwinding is different from one driven by an inventory draw, and a trader should be able to say which they think it was.
    5. Then the technical level if asked, without pretending it is more than it is: 'the market has failed twice around X, and positioning is long, so a break below Y probably accelerates.' Say it as a description of where the stops are, not as a forecast.
    6. The honest framing if you genuinely do not know the level: say so, give your best estimate with a range, and say when you last checked. 'Brent was around the mid-60s when I looked yesterday' is a perfectly good answer. Inventing a precise number you cannot defend is the one thing that ends the conversation.

    Where candidates lose it

    Quoting a number without saying which contract, or being unable to name the curve shape. And never invent a level — an S&T interviewer knows the screen and will catch a fabricated number instantly. Have three or four markets you genuinely follow daily rather than a shallow view on everything.

    Expect next

    • Is the curve in contango or backwardation?
    • Where is the Brent-WTI spread and what drives it?
    • Was that last move flow or fundamentals?
