Carry Trades Ranked: From Sleeping Pill to Adrenaline Shot

Every trading collective has its house spreads — the structures that get passed around like family recipes, defended in chat, and occasionally blamed for a bad quarter. We polled the group and ranked our six core carry and calendar trades by a metric nobody publishes: nerves required. Margin efficiency and holding period matter, but let's be honest about what actually determines whether you keep a trade on.

6. The Treasury Butterfly Nap (ZB/ZN Fungible Spreads)

The snooze button of the list. Tight intermarket margins, deep liquidity, and a structure that mostly just sits there collecting small mean-reversion edges between curve points. Typical hold: days to weeks. Failure mode: a hot CPI print that reprices the whole curve in one session and makes your 'boring' position move like an outright. It's the trade you check once a day, which is exactly why newer members underestimate it.

5. Grain Calendar Spreads (ZC/ZS Old Crop vs. New Crop)

Margin-efficient, slow-moving for most of the year, and then violently not slow-moving around USDA report days and weather scares. Holding periods run weeks to a full season. The failure mode is predictable and therefore forgivable: a drought headline turns a 4-cent spread into a 20-cent spread overnight. Anyone who trades these without a weather model opinion is renting, not carrying.

4. The Crack Spread (CL vs. RB/HO complex)

Where the list starts requiring actual attention. Refining margins mean the trade pays when the complex relationships hold, and the margin offsets are genuinely attractive. Typical hold: one to three weeks. Failure mode: a refinery outage or an unexpected regulatory headline that decouples product from crude for a week. One member's rule: never carry a crack through a hurricane season without halving size.

3. The Gold-Silver Ratio Trade (GC vs. SI)

Everyone's favorite 'it always comes back' trade, which is precisely the problem. The ratio mean-reverts on a long enough horizon — but the margin requirements on the silver leg are punishing relative to the spread's daily movement, and silver can run 5% against you in a session on zero news. Holding periods: weeks to months. Failure mode: a silver squeeze that makes the ratio 'cheap' for three more months while your account bleeds. It pays the rent, but it collects it with attitude.

2. The Crude Term Structure Roll (CL calendar spreads)

Selling contango or owning backwardation sounds like free money until the curve kinks. The front-month spreads are liquid and the margins are reasonable, but the roll calendar creates recurring execution risk — every month you're paying the toll. Holding period: rolling, indefinitely, if you're disciplined. Failure mode: a storage-crisis-style dislocation where the front blows out against you and the spread you thought was a cash cow becomes a margin call with a ticker symbol. Ask anyone who was around in April 2020.

1. The Equity Index Ratio (ES vs. NQ or RTY)

The adrenaline shot. The growth-to-value or large-to-small ratio trends hard, and the temptation to lean into it is enormous — but the NQ leg can gap 2% while ES barely twitches, and the margin on the pair reflects that volatility. Typical hold: days, not weeks, because nobody's nervous system survives longer. Failure mode: a rotation day where both legs move 'correctly' but the intra-session whipsaw stops you out three times. Two members trade it; both admit they've been shaken out of winners.

What the Ranking Actually Teaches

Notice the pattern: the trades at the bottom of the list fail slowly and predictably, which is why they survive. The trades at the top fail fast and asymmetrically, which is why they're exciting and, net of all the stops and restarts, often less profitable than the butterfly nap everyone laughs at.

The desk's collective conclusion, for what it's worth: carry the boring spreads big and the exciting spreads small. The rent gets paid by the structures that don't need you to watch them.
