中金：DCN与类雪球产品规模估计与对冲机制研究

Core Viewpoint - The recent low level of stock index futures basis is linked to the dynamics of Dynamic Coupon Notes (DCN) products, which are believed to potentially reduce the basis rather than deepen it [1][4][31]. Group 1: Stock Index Futures Basis - The recent basis rates for IC and IM have reached historical lows, influenced by factors such as hedging, trading, dividend cycles, and policy restrictions [2][6]. - The basis rates are expected to exhibit cyclical fluctuations, with the current deep basis potentially benefiting the yield and scale of structured products like DCN and snowball products [2][7]. - The basis rates for IC and IM, after adjusting for dividends, remain at historical lows, indicating persistent pressure on the stock index futures market [8][9]. Group 2: Dynamic Coupon Notes (DCN) - DCN is characterized as a type of snowball product without an observation for knock-in, providing fixed income features combined with derivatives [3][25]. - The structure of DCN allows for monthly interest payments if the index price meets certain thresholds, with a risk of loss if the index falls below a specified level at maturity [25][30]. - The hedging mechanism of DCN is smoother compared to traditional snowball products, as it lacks a knock-in feature, resulting in a more stable impact on the stock index futures market [4][31]. Group 3: Market Dynamics and Product Scale - The total scale of snowball-like structured products is estimated to be around 100 billion yuan, which is less than half of the scale at the beginning of 2024 [4][31][38]. - The recent deep basis in stock index futures is expected to lead to a rapid increase in the yield and scale of DCN and similar structured products [4][45]. - The issuance of DCN products is seen as attractive in a low-interest environment, potentially leading to increased demand and market activity [4][31].
