What is a receive-pay curve trade in swap markets?

Question

In interest rate swap markets, 'receiving' means receiving FIXED and paying FLOATING; 'paying' means paying FIXED and receiving FLOATING.

**'Receive 5s, pay 10s'** = receive fixed on a 5-year swap, pay fixed on a 10-year swap, both notionals sized to be duration-neutral (or sometimes DV01-neutral).

**What this expresses**: A bet that the 10s–5s swap curve will FLATTEN (10-year rates rise less than 5-year, or 10s fall more than 5s). You profit from curve flattening.

**Why**: Receiving fixed on 5Y = long duration 5Y (like buying a 5Y bond). Paying fixed on 10Y = short duration 10Y (like shorting a 10Y bond). So net position: long 5Y / short 10Y. If spread between 10Y and 5Y yields narrows (flattens), long-short pair profits.

Worked example: Galvanic Swap Desk executes:
- Receive 4.10% on $300M 5-year swap (pay SOFR)
- Pay 4.55% on $147M 10-year swap (receive SOFR), notional sized to match 5Y DV01.

Current curve: 10s–5s = 45bps. Dealer expects flattening to 20bps over 6 months.

If 5Y drops 5bps (to 4.05%) and 10Y drops 30bps (to 4.25%) → curve flattens to 20bps. Receive leg: gain from 5Y drop ≈ $300M × 4.55 duration × 0.0005 = $683K. Pay leg: gain from being short as 10Y drops is negative for a short... wait, paying fixed and receiving floating means you benefit when rates RISE. If 10Y drops 30bps, pay-fixed loses: $147M × 8.40 × 0.003 = −$3.7M. Net result: −$3M.

But wait — if you sized for flattening, scenarios where 10Y drops more than 5Y flatten the curve but still hurt the pay-fixed leg. The CORRECT bet needs the curve to flatten via 5Y falling MORE than 10Y, or 10Y rising MORE than 5Y. Sizing and scenario matter.

**Key mechanics**: Swap curve trades isolate slope without big duration bet. Carry (positive if short end has lower rate than long end) and roll also contribute.
