Macau casino operators’ stocks are soaring on news that China’s Guangdong province will lift its 14-day quarantine for individuals returning from the world’s top gambling hub.

On Monday, authorities in Guangdong and Macau announced “the orderly promotion of the normal exchange of personnel” between the two regions. The change is scheduled to take effect at 6am on Wednesday, July 15.

Guangdong imposed its Macau-specific COVID-19 quarantine rules in late-March, requiring all individuals arriving on the mainland from Macau to self-isolate for 14 days (at their own expense). Guangdong is China’s most populous province and the closest to Macau in geographic terms, making it the single largest source of gamblers for Macau’s casinos.

All individuals seeking Guangdong access will need to provide a negative COVID result from an approved testing site and apply for entry at least 24 hours prior to arrival. The quarantine will still apply to individuals who (a) display COVID-19 symptoms, (b) have had contact with COVID patients or (c) have traveled overseas in the 14 days prior to arriving in Guangdong.
