NEW DELHI — As the chaos surrounding Prime Minister Narendra Modi’s ban on high-currency bills entered its ninth day, the government moved Thursday to address some of the problems amid signs of growing impatience with the slapdash way the policy seems to have been carried out.

Since the move was announced, retail commerce has slowed, farmers who deal almost exclusively in cash have had no buyers and people have waited in long lines at banks and ATMs in hopes of getting a paltry amount of the new notes the government is in the process of printing.

To deal with the continuing liquidity crunch, the government on Thursday cut the exchange limit to 2,000 rupees, or about $30, from 4,500 rupees, or about $66, effective Friday, so that the cash would be more widely distributed. This week, banks began using indelible ink to mark fingers of people who had exchanged old notes to weed out repeated exchanges.
