Hong Kong-listed casino shares gained Tuesday on news Macau will gradually start reissuing individual-visitor visas from Aug. 12.

Macau said it plans to first ease restrictions on visitors from the neighboring city of Zhuhai. The market expects the visitor visa issuance to be gradually resumed with the rest of Guangdong province in the near term, KGI Securities said. The province accounts for 46% of total mainland tourist volume for Macau.

Macau will also ease the requirement for a 14-day quarantine for visitors entering from mainland China from Wednesday, JPMorgan added.

Shares of Hong Kong-listed casino stocks broadly gained at market open. Sands China Ltd. gained 6.7%, MGM China Holdings added 5.9% and Wynn Macau Ltd. jumped 6.9%.

Macau's gaming revenues plummeted amid the Covid-19 pandemic after the individual-visitor visas were suspended in January. July's gross gaming revenues fell 94.5% from a year earlier, the fourth straight month in which gaming revenues fell more than 90%.
