The Delhi Golf Club reserves memberships for the top 50 officials who can afford its entry fee of 300,000 rupees ($5995) - more than six months' salary.
One senior Delhi Golf Club official told the Daily Telegraph that while many of its members welcomed Modi's empowerment of civil servants, they were fearful their lifestyles might be under scrutiny.
"They're all talking about it," he said. "In the previous Government they were just passing files, not taking decisions. They had more time for themselves and got away for more golf."
More than 250 senior departmental secretaries are believed to be members of elite golf clubs in the capital, including several built illegally by the army on government-owned land.
Mohan Guruswamy, an analyst on government affairs, said Modi's actions could end "crony capitalist" relationships between civil servants and businessmen that have flourished on the fairways and "19th hole" bars.
"We have a bureaucracy which is undisciplined, corrupt and venal to its core," he said.
