Macau casino gaming revenue fell by one-third in September, the 16th straight month of year-on-year declines in the world’s top gambling jurisdiction.

Gaming revenue fell 33% to MOP 17.1b (US $2.2b), slightly better than the 36.5% shortfall recorded in August. September’s rate of decline was also the smallest since January, although September’s total is the lowest monthly tally so far in 2015, edging out June’s MOP 17.35b. For the year to date, Macau’s gaming revenue is down 36% to MOP 176b ($22b).

The already suffering local gaming industry was further rocked in September by an internal theft scandal at Dore Entertainment Co Ltd, a junket operator that controls several VIP rooms at Wynn Macau. The original reports listed the stolen sum at around HKD 2b ($258m) although this has since been reduced to a direct theft of HKD 100m from the junket, plus hundreds of millions more that was stolen directly from junket investors.

Whatever the actual number, the theft did a number on Macau’s junket industry, which was already suffering from severely tightened liquidity. Junket investors have been pulling out their money and the depressed VIP sector has led junket giant Neptune Group to publicly muse about getting out of the Macau VIP business altogether.
