HIP-3 Perpetual Futures Arbitrage in Action: SK Hynix ADR Premium Trading Opportunity
HIP-3 Perpetual Futures Arbitrage in Practice: The SK Hynix ADR Premium Trade
Following its Nasdaq listing, a significant price gap emerged between SK Hynix's ADR (SKHY) and its underlying share (SKHX). During this period, the HIP-3 builder TradeXYZ launched perpetual futures markets for both on Hyperliquid. The divergent funding rates between these two markets offer a clear case study on the capabilities and limitations of stock perpetuals.
The premium, which soared to 51% on July 14th, was primarily driven by closed arbitrage channels. The new ADR issuance did not involve depositing existing shares, and conversion between the underlying share and the ADR is not permitted until after July 29th. With strong US institutional demand facing constrained supply, the price gap widened.
On Hyperliquid, the funding rates for SKHX and SKHY moved in opposite directions, revealing traders executing a pairs trade to bet on the premium narrowing—buying SKHX (underlying) and shorting SKHY (ADR). This highlights key insights:
1. **Ability to bypass traditional market friction:** The trade can be executed with USDC on a single platform, avoiding complexities like currency conversion, foreign accounts, and ADR borrowing.
2. **Missing tools to separate funding costs:** The trade inherently carries the cost of funding rate payments/receipts, as perpetuals reflect but do not force convergence between the two underlying indices. Instruments to hedge this variable cost are not yet available for HIP-3 stocks.
3. **Function as a leading indicator:** The SKHY pre-IPO market accurately predicted the Nasdaq opening price, and SKHX trades during KRX closures, providing price discovery.
4. **Inverse relationship with accessibility:** The SKHX perpetual, serving a market with fewer native hedging tools, sees much higher volume and sustained funding rates than the SKHY perpetual, which exists alongside a deep spot and options market.
The focus now shifts to July 29th, when share conversion may partially open, though structural limits on creating new ADRs may persist. Regardless of the premium's path, Hyperliquid remains the primary venue to express a view on this spread via perpetual futures.
