Funding Rate Indices

BTC Funding Rate Perpetual (BTCSWP‑USDYP)

A tradable swap index on the Hyperliquid BTC funding rate. It tracks excess funding; the difference between realized BTC funding and a trailing average reference (K1).

This creates a two‑sided instrument to:

• hedge funding costs,

• speculate on regime shifts,

• and trade deviations from medium‑term funding trends.

Key Parameters	Details
Collateral	USDYP
Initial Oracle Price	50,000.00
Open Interest Cap	$10,000,000
Funding Multiplier	1

Oracle model

During the hour, the oracle nowcasts the pending rate using a premium‑based model. At the hourly boundary, it ingests the final realized funding rate from Hyperliquid and true‑ups the cumulative index for accuracy.

Additional constraints:

• wire price moves are clamped (±1% per update),

• quantized to 6 decimals.

Because this is a synthetic index, MarkPx is designed to track OraclePx closely.

Funding setup

Configured with a fixed‑leg component:

• setFundingInterestRates: -0.000097232 per 8hr (≈ 2.54% APY magnitude)

Economic interpretation:

• Longs receive the fixed leg as compensation for what the cumulative index subtracts,

• the combined return is designed to track the underlying funding stream more directly.

Strategies

• Hedge (long BTC perp): go long BTCSWP for a portion of notional to stabilize funding costs.

• Speculate: long if you expect funding to exceed its trailing average; short for the opposite.

Notes & risks

Funding is regime‑dependent and can spike. Use conservative leverage and understand liquidation behavior.
