It may be monsoon season in Las Vegas but there's a typhoon blowing through Macao's casino economy. A series of bulletins from J.P. Morgan outline a worrisome trajectory for China's gambling enclave.

City of Dreams: a flop

June 23: The South China Morning Post reports service cutbacks in Macanese air traffic during January-March. Low-cost carrier Air Asia held steady, but China Eastern Airline scrapped all flights, Xiamen Airline slashed service by 59%, followed by Malaysia Airlines (-38%). Single-digit declines were noted at Air Macau (-9%) and Viva Macau (-4%). Although recently de-licensed carrier East Star had been shedding flights (-40%), competitors did not appear to be moving to fill the void.

June 24: Macao's Special Administrative Region Statistics & Census Service reports a 20% visitation decline in May, to 1.6 million tourists. Of those, fewer than half were from the mainland (-27%) and 55% were day-trippers. Only 13% are coming from outside Hong Kong, Taiwan or the mainland.

July 1: News agency Lusa has preliminary revenue numbers for June (the first month for City of Dreams) and the comparisons, by Macao standards, are terrible: -17%, for $1.05 billion. So far, the casinos are tracking ahead of the government's revenue projections -- which were pretty dire ($892K/month) already.

There's a silver lining for Sheldon Adelson, whose Sands Macao and Venetian Macao rebounded, running Stanley Ho's myriad casinos a close second in market share, 26% to 30%. Wynn Macau fell toward the pack, which was as follows: Wynn 14% (a humiliating setback; it had been only three points behind Las Vegas Sands in May), Galaxy 12%, Melco Crown International down a point to 9%, and MGM Mirage bringing up the rear, as always, with 8%.

Sands Macao: Adelson's best-ever investment

Buoyed by Sands' Macao numbers, Morgan analysts are bullish on Adelson, mainly because of "reasonable near-term and achievable expectations for its LV Strip properties and our belief that its LV properties are outperforming its peers." Just when you think Sheldon's painted himself into a corner, he seems to find a means of escape ... which may be why some of us were less skeptical of the financial hurdles facing Sands Bethlehem and the Cotai Strip™ than we should have been.

There seems to be a school of belief that if one keeps saying that visa restrictions from mainland China to Macao are about to be relaxed, it will miraculously happen. Not if Peking muckety-mucks keep seeing headlines like this. More to the point, bailout money that was intended to induce Chinese banks into writing more loans, thereby stimulating production, is flowing to the casino tables instead. That's a scenario highly reminiscent of the circumstances that led Peking to crack down on Macanese traffic several times already.
