Many of the wealthy Thais who come to investment manager Charles Blocker have a question for the generals who seized control of the country in a military coup last week: What took you so long?

"It's business as usual," said Blocker, head of boutique investment firm Invision Capital Partners in Thailand, where the company manages some $140 million of cash from individual investors and family offices.
