MACAU (AFP) - Macau's gaming revenue was virtually wiped out in April as casinos suffered their worst month on record owing to measures put in place to prevent the spread of coronavirus in the tourist-dependent city.

Figures from the Gaming Inspection and Coordination Bureau showed gross gaming revenue of 754 million patacas (S$134 million) last month - a drop of 97 per cent from the US$3 billion (S$4.3 billion) raked in during the same period last year.

The former Portuguese colony shuttered all its casinos for two weeks in February as the virus burst out of central China but while they have since reopened, anti-virus measures still mean mainland visitors cannot enter the city, leaving casino tables devoid of gamblers.

Some of the big operators are bleeding millions a day in operation costs.

But unlike many global businesses taking a hit during the global crisis, Macau's major casinos are well positioned to weather the current maelstrom as they sit on huge piles of cash from the boom times.

And unlike many Las Vegas operators, they do not have sizeable debt piles.

In a client note from early April, JPMorgan Chase analyst D.S. Kim said operators "have ample liquidity to survive this unprecedented period of 'near-zero revenue' for over a year", Bloomberg News reported.

Galaxy Entertainment, for example, ended 2019 with US$6.8 billion in cash reserves.

But the colossal drop will hit Macau's government hard as it draws as much as 80 percent of its revenue from the gaming sector.

Many analysts expect Macau's fortunes to rebound in the early summer if travel restrictions are lifted and share prices have risen from their near four-year low back in March.

The gambling hub made impressive strides against the coronavirus outbreak and has not discovered any new cases for the past 20 days.

Neighbouring Hong Kong has also not reported a new case for the five days.
