There has been no action in Britain since March 17, when meetings took place behind closed doors at Wetherby and Taunton.
The British Horseracing Authority has been formulating plans for a resumption, but must wait to be given the all-clear from the Government to restart the sport and Dettori is anticipating a tough spell for the industry.
He said: “Racing is pretty much funded by sponsors, attendances and betting turnover and none of those three things are happening at the moment, so when racing does return, you would think there will be a substantial drop in prize-money.
“Racing will definitely by affected — while it's an industry, there are plenty of people that have horses as a hobby and I think there will be hard times for a period to come.”
Some nations have been continuing to race under strict protocols and Dettori is taking heart from that.
He said: “I'm looking at Australia, Hong Kong and Florida where they are racing behind closed doors. It is possible and we aren't the same as football and rugby as we aren't a contact sport.
“We can still be a metre or more away from each other, so there's a chance we can start behind closed doors. The Government reviews the lockdown next week, so we will have to see if there is any relaxation on the rules and we will know more then.”
The BHA has already outlined some of the measures it is planning for the return of racing, with a phased approach involving restricted field sizes and only senior jockeys allowed to ride in the initial stages.
No spectators will be permitted before at least the beginning of June, with Royal Ascot already announcing a behind-closed-doors policy, while the first four Classics — the 1000 and 2000 Guineas, Oaks and Derby — have been pushed back in the calendar.
Dettori feels it is crucial to the breed to ensure those key races are contested and while he would prefer the Derby to remain at Epsom, he is open to the idea of an alternate venue if circumstances dictate.
He explained: “They had the Derby at Newmarket during the Second World War and I think the Epsom Downs are public grounds, so it might be hard to keep people away. I think that was the worry.
“Personally, I would prefer the Derby to be at Epsom. The most important thing though is to have the Classics — it doesn't matter if they're a month or six weeks later.
“We have to protect this three-year-old generation as we are the custodians of the thoroughbred breed.
“It will be odd to have Royal Ascot behind closed doors, though.”
Despite there being no on-course action, life continues as near to normal as possible in racing stables and Dettori has been regularly riding out for John Gosden.
He said: “I rode out on Wednesday morning and the horses are well. We had a mild April so that has really brought them forward in their coats and we will be ready to start when we're allowed.
“They may be starting in France on May 11, so that's got to be a good thing for everybody.”
Dettori has dual Prix de l'Arc de Triomphe winner Enable and top stayer Stradivarius to look forward to when the season eventually gets under way.
Enable's ultimate target is an unprecedented Arc hat-trick at ParisLongchamp in October, while Stradivarius bagged a £1million bonus for the second successive year in 2019 in claiming the Yorkshire Cup, the Gold Cup at Royal Ascot, the Goodwood Cup and the Lonsdale Cup at York.
Dettori reports his star mounts to be in fine heart and believes the delayed start to the season will not trouble either runner unduly.
He said: “I saw Enable on Wednesday morning, she looks good and fresh, and I rode Stradivarius last week and he was in good form.
“The situation doesn't really affect them as their campaigns are really from summer through to the autumn, so they're not really going to miss out on too much.
“It's more of an issue for the three-year-olds, with the Guineas and the Derby so important. Fingers crossed, we will know more after May 7, but it is a testing time.”
