The BBC has said it will have to "think hard about every pound" it spends on new programmes because of financial pressures during the current lockdown.
Delays to a new licence fee regime for people over 75 and problems collecting fees are among the challenges cited.
Staff have been told the BBC will have to find £125m savings this year.
Senior leaders will take a pay freeze until August 2021 and all non-essential recruitment will be put on hold as part of the cost-cutting measures.
Staff will also be invited to work part time or take unpaid leave if they find it "helpful" during the lockdown.
In a briefing on Wednesday, director general Tony Hall said other reasons behind the cash shortfall were a delay to a plan to cut 450 jobs, and uncertainty around commercial revenues.
Other broadcasters have been badly hit during the crisis, with ITV last month cutting its programme budget by £100m and Channel 4 cutting £150m from its programming.
On Wednesday, Channel 4's director of programmes Ian Katz said the broadcaster would have to cut back on drama and produce "lower tariff" shows.
"In the next few months I don't think we will see any new dramas getting up and running," he said.
