Minimum margin ratios increase in China

Chinese exchanges have reinstated a 100% minimum margin ratio requirements for leveraged securities trading.

The requirement was reduced to 80% in June 2023, boosting margin trading and transaction volumes. As activity and liquidity in the margin trading market has increased, and in line with counter-cyclical adjustment arrangements, the China Securities Regulatory Commission (CSRC) has approved a return to the 100% ratio for new contracts.

Outstanding margin contracts and their rollovers will retain the 80% requirement.

This change will reduce leverage levels and safeguard investor rights and interests, the Shanghai Stock Exchange noted, while encouraging stable market momentum.

According to CEIC data, margin transactions at the Shanghai Stock Exchange reached a peak of RMB 1.34 trillion (US$192 billion) outstanding on 14 January. An all-time record high of RMB 1.5 trillion (US$215 billion) was recorded on 18 June 2015.

Last year, exchanges spoke to regulators about limiting colocation services in the country.

All CEDX products have been set to close only, with any products without open interests placed on a trading halt. They will then be delisted.

Open positions on CEDX will be cash-settled at fair market value and the CEDX equity options liquidity provision programme will end on 20 February. Connectivity to the environment will cease on 23 February, with the service decommissioned. Billing will end on 27 February.

Further information about physical connections to the exchange service will be shared in the coming weeks, Cboe Europe stated.

In November 2025 CEDX reported 20,345 contracts traded, the fourth most active month since it launched. Open interest was at a record high of 52,626 contracts.

The announcement follows the initiation of a sales process for Cboe Australia and Cboe Canada last year.

Exegy buys NovaSparks to strengthen its FPGA offering

Exegy has acquired French field programmable gate array (FPGA) trading solution specialist NovaSparks. The firms said the deal expands Exegy’s ultra-low latency market data normalisation and distribution capabilities. Financial terms were not disclosed. 

Exegy, backed by private equity firm Marlin Equity Partners, has previously acquired Vela Trading Systems in 2021, and later added FPGA trading technology provider Enyx in 2022.  

NovaSparks is known for its FPGA ticker plant and feed-handling technology, which normalises exchange feeds and builds order books in hardware to minimise processing time and network jitters. The company markets NovaTick as its flagship product and says it supports dozens of global venues across equities, futures and options. 

The largest FPGA manufacturers AMD, and intel owned Altera did not answer to request for comments on the deal. According to Skyquest, the FPGA hardware market was valued at US$11.6b billion in 2024 and poised to grow four-fold in the next decade. 

Market participants told Global Trading, that ‘off the shelf’ FPGA technology is becoming a minimum requirement for any active institutional trading operation using smart order routers.

In its announcement, Exegy said it intends to maintain existing NovaSparks offerings and invest in new solutions that combine both firms’ technologies. Exegy chief executive David Taylor said the purchase is part of the group’s strategy to broaden its low-latency offering. 

He said: We are thrilled to welcome NovaSparks clients to Exegy. We have a strong track record of blending the strengths of talented teams and proven products to elevate the user experience and deliver greater value to our clients, and we are excited to continue this strategy with NovaSparks,”  

Exegy previously sued Novasparks over patent infringements before announcing a settlement of that dispute in 2023. 

For Exegy, the acquisition brings additional FPGA engineering know-how and a expanded product line focused specifically on market-data normalisation and distribution.  

NovaSparks’ CEO, Luc Burgun said: “Joining forces with Exegy allows us to improve our innovation and customer support capabilities. Our clients will continue to receive the ultra-low latency performance they rely on, but now with the backing of Exegy’s global presence and services infrastructure.”
