SEBI Reportedly Eases Arbitrage Fund Rules to Support Closing Auction
India’s market regulator has reportedly made a small rule change for arbitrage mutual funds.
These funds try to earn money from price differences between shares and futures.
They usually have to protect themselves by keeping both positions fully matched.
The closing auction has not attracted enough trading activity since it began on 3 August.
The new rule may let a fund briefly leave up to 1% of its plan unmatched.
This could make it easier for funds to participate in the auction.
Some large investors have stayed away because low trading volumes can cause bigger price movements.
SEBI is also considering wider changes to how the closing auction works.
SEBI has reportedly allowed arbitrage mutual funds to carry temporarily unhedged positions of up to 1% of a plan.
The measure seeks to attract liquidity to the closing auction session, which has struggled since launching on 3 August.
Arbitrage funds held about ₹3 lakh crore ($31 billion) in combined assets at the end of August.
Funds previously faced difficulty participating because they were required to remain fully hedged while buying shares and selling futures.
SEBI has also proposed broader changes to the auction framework amid concerns about thin trading and sharp price swings.

- The Securities and Exchange Board of India (SEBI), arbitrage mutual funds, asset-management companies, and institutional investors.
