MUMBAI (Reuters) - The Singapore Exchange (SGX) SGXL.SI said on Saturday a court-appointed arbitrator had told it to continue listing and trading SGX Nifty contracts beyond August 2018, during a dispute resolution with India's National Stock Exchange (NSE).

The two exchanges have been locked in dispute after India’s three main bourses unexpectedly announced in February they would stop licensing their indexes to foreign bourses from August.

SGX responded that it would launch successor products to its flagship Indian equity derivative products on June 4.

Now NSE and SGX have been ordered “to facilitate the continued listing of SGX Nifty products for at least two successive contract month maturations beyond the arbitration’s completion date”, SGX said in a statement.

The arbitrator has also asked SGX not to offer its proposed new India equity derivative products until the final decision, it said.

“Arbitration proceedings are continuing and the hearings on evidence are expected to commence in early 2019,” the statement said.

SGX had postponed the launch of a set of new India derivatives products after an Indian court in May referred a dispute around the proposed offerings to an arbitrator.

In a statement issued on Saturday, NSE also confirmed the interim order of the arbitrator.

The NSE had sought an interim injunction against the launch on grounds that the offerings infringed the intellectual property rights of its unit India Index Services and Products (IISL), which runs the Nifty index.

The Bombay High Court then asked a senior retired judge to arbitrate in the matter, and resolve the issue by June 16.

However, the June 16 interim order, which was reviewed by Reuters, laid out a timeline for filing of claims and counter-claims and set Nov. 21 for hearing of the issues, with further directions to be provided on June 18.

Over the past two decades, SGX has become the most popular market for foreign investors to bet on Indian equity indexes, with Nifty 50 futures SINc1 tracking the NSE's main index .NSEI.

But NSE, BSE Ltd BSEL.NS and Metropolitan Stock Exchange moved to end licensing deals with foreign bourses so as to stem the loss of trades to overseas rivals, following SGX's plans to launch trade in single-stock futures contracts.

The Indian government backed the decision, as it is keen to draw investors to an international financial center being developed in Prime Minister Narendra Modi’s western home state of Gujarat, sources say.
