Why High-Premium LOFs Crashed After the New Exchange Proposal

China's market for listed open-ended funds, known as LOFs, was jolted between 10 and 12 August after the Shanghai and Shenzhen stock exchanges proposed new rules to wind down several categories of these products. The catalyst was a consultation notice published on 7 August that would set explicit termination procedures for commodity futures LOFs, QDII LOFs and very small LOFs.

On 10 August the pain was concentrated in funds that had traded at outsized premiums. Invesco Great Wall Global Chip LOF opened at its daily limit down, while Southern Crude Oil LOF fell 9.26%, E Fund Crude Oil LOF dropped 7.10% and Harvest Crude Oil LOF lost 6.89%. Guotou UBS Silver LOF, the market's only commodity futures LOF, declined 6.77%.

Under the proposal, commodity futures LOFs and QDII LOFs would have to end their exchange listings by 31 December 2027, with a transition period because their premiums are often driven by structural constraints: exhausted QDII foreign-exchange quotas or limits on futures positions can shut the over-the-counter subscription channel. Small LOFs, by contrast, would get no transition period.

Wind data cited in the report show 402 LOFs with valid scale data, of which roughly 125 - more than a quarter - would be affected, representing about RMB 26 billion in on-exchange scale. The market's first reaction was panic, the second day brought divergence, and by 12 August some of the most stretched premiums had narrowed sharply.

What the LOF Termination Plan Means for QDII, Commodity and Mini Funds

QDII and commodity LOFs: the premium problem is a supply problem

The high premiums in these products are not primarily a story of irrational demand. When QDII foreign-exchange quota is exhausted or a commodity futures position limit is reached, the over-the-counter subscription channel closes. That breaks the cross-system arbitrage mechanism that normally keeps exchange prices close to net asset value, leaving the listed price free to detach. The exchange plan therefore targets the structural source of the distortion. The repricing was rapid: on 7 August, the 16 suspended-subscription QDII LOFs carried an average premium of 5.74%, but by 12 August that had fallen to 1.28%. Open-subscription QDII LOFs moved from a 0.73% discount to about 0.48%.

Mini LOFs face tighter discipline with no transition

The proposal gives no grace period to very small products. Wind data identify 113 LOFs with on-exchange scale below RMB 10 million. Under the planned mechanism, a product below that threshold for 40 consecutive trading days would trigger a risk warning, and 60 consecutive trading days would lead to a trading halt and the start of delisting procedures. The second trading day of the market shakeout showed why such rules matter: Caitong Sci-Tech LOF fell 9.08%, while CICC Sci-Tech Theme LOF was pushed to its limit up because scarce on-exchange liquidity made the price easy to move.

Fund managers are choosing conversion over disorderly exits

Fund companies interviewed said they had set up working groups to review affected products. For commodity futures and QDII LOFs, the preference is to use the transition period until end-2027 rather than delist while a product is trading at a high premium. If a manager converts an LOF into an ordinary over-the-counter fund, the plan requires a 20-trading-day holder choice period, during which on-exchange subscription would be suspended but redemption and cross-system transfer would remain open. Analysts quoted in the report expect LOF arbitrage opportunities to become less frequent and less profitable, but not to disappear entirely, because larger and more liquid LOFs can still support inter-market arbitrage.

What Investors and Fund Managers Should Watch as the 2027 Deadline Approaches

  • Do not assume a 2027 deadline removes immediate pricing risk. Suspended-subscription QDII LOFs compressed from an average 5.74% premium on 7 August to 1.28% by 12 August, showing how quickly premium overvaluation can unwind.
  • Check small LOF holdings against the RMB 10 million threshold. Unlike QDII and commodity funds, mini LOFs would receive no transition period, with risk warnings at 40 consecutive trading days and delisting procedures at 60.
  • Use the planned 20-trading-day holder choice period if a product is converted. Fund managers are expected to suspend on-exchange subscription during conversion but keep redemption and cross-system transfer available, so the choice window is the practical moment to act.
  • Treat historical high-premium LOF trades as less reliable going forward. Arbitrage will not vanish for larger liquid products, but the new rules are explicitly designed to reduce both the frequency and size of those opportunities.

Risk & Opportunity Assessment

Commercial RiskHighThe proposal affects about 125 of 402 LOFs and roughly RMB 26 billion in on-exchange scale, forcing fund companies to restructure or wind down commodity futures, QDII and mini LOF products.
Competitive RiskMediumAffected products may lose their listed wrapper while larger, more liquid LOFs remain tradable, shifting product shelf space and arbitrage activity toward the survivors.
Regulatory RiskHighThe exchange notice introduces specific termination procedures, a 2027 deadline for QDII and commodity LOFs, no transition for mini funds, and new star-label identification rules.
Reputation RiskMediumFund companies now face investor losses from premium compression and must issue repeated risk warnings or temporary trading halts, which could expose them to complaints from buyers of high-premium products.
Technology DisruptionLowThe story concerns listing rules, product structure and market liquidity, not a technological change.
Commercial OpportunityMediumThe transition period allows managers to convert affected LOFs into ordinary over-the-counter funds while preserving redemption and transfer channels, offering a path to retain assets in a cleaner structure.
