Watmore said ECB's 'ambition' would probably have to be reduced significantly.
London: New ECB chairman Ian Watmore feels the COVID-19 pandemic would leave the board with "very severe cash constraints and a global game in crisis" if it continues to rage on and disrupts the next domestic season.
Watmore had begun his tenure last week, succeeding Colin Graves as England and Wales Cricket Board (ECB) chairman.
The coronavirus outbreak had forced a cricket shutdown in March and Watmore said ECB has "a guaranteed shortfall of 100m this year, and it might be as high as 180m" against a "pre-COVID whole game" income of around 475m anticipated for 2020.
He said recovering from the losses of the 2020 season will require "a mindset of "same ambition, just less money'" but it could get much more serious if the global health crisis continues to affect the game next year as well.
"Provided we can get cricket back to somewhere near normality next season ... we have four years to recover one year's losses, where each of those years has double the income of the recent past," Watmore wrote in a blog post on the ECB's website.
"What is more concerning is the possibility that our next domestic season is severely disrupted by Covid too - with more cricket cancelled, played behind closed doors, or with very limited crowds.
"At this point, we will have two years of losses to recover with only three years left of the current funding cycle, coupled with very severe cash constraints, and a global game in crisis."
Watmore said ECB's "ambition" would probably have to be reduced significantly.
"We must have a plan for this were it to occur, but the whole game and governments around the world must equally do everything we can to avoid this situation occurring."
Watmore said "an obsessive focus on cash and cashflow, combined with a sharp period of cost reduction and efficiencies across the whole game, starting with the ECB itself will be essential to reducing outgoings and buying time".
The resumption of international cricket amid the pandemic with series against West Indies, Pakistan and Australia has helped England to bridge the financial gaps but Watmore warned this is "ephemeral".
"The game has also been brilliant in getting behind-closed-door men's and women's cricket going, internationally, at county/regional level and recreationally. While it appears as if the game has bridged the financial gaps, this is ephemeral and the financial day of reckoning is yet to come."

Pakistan will try to work on their batting and look to avoid a dubious repeat from 2019. England on the other hand will look to strengthen their lead.
England last played in Pakistan in 2005 and were due to visit again last year until pulling out at short notice after New Zealand also cancelled a tour citing safety concerns.
With two matches already played, the England-India T20I series is currently leveled 1-1. The third match will be played at Bristol.
