He told the BBC the 48% who had voted to Remain felt "disenfranchised" and it was not clear "what we are moving to".
He said that "if the will of the people shifts" as details of what Brexit means for the country begin to emerge, then, "Why shouldn't we recognise that?"
Prime Minister David Cameron and Labour Leader Jeremy Corbyn have both ruled out a second EU referendum.
When asked on Radio 4's The World This Weekend whether "keeping our options open" meant a second EU referendum, Mr Blair replied: "It means whatever we decide it should mean as we see how this debate develops."
But he said the case for leaving the EU had "crumbled".
He said the government should engage now with other European Union countries to see what room there was for manoeuvre, stressing the continuing importance of David Cameron's role in this, rather than waiting for the outcome of the Tory leadership race.
He said the referendum had been an event of "seismic importance" but warned the focus in the wake of Mr Cameron's resignation as prime minister would be on the Conservative leadership contest rather than the country's national interest.
He said that once the practical effects of the UK's decision to leave the EU became clearer, then there should be a role for Parliament.
"Right now it's clear. We're leaving," he added.
"But we don't know what we're going to. If what happens as we develop this negotiation with the rest of Europe, it does become clear - and let's suppose for example we find we're shut out of the single market, we have to rely on the World Trade Organisation as the route back in to different trade deals....
"My point is this. We are sovereign. Let's just keep our options open."
The former prime minister said Britain had "diminished" its place in the world and would have to "fight to get it back".
There have been some calls for a second referendum and an online petition calling for one has been signed by more than four million people, although thousands of signatures were removed after it was hijacked by hackers.
Legally speaking, the petition would have to show a clear majority of the electorate now favoured Remain for a second referendum to be triggered, says the BBC's legal correspondent Clive Coleman.
The five Conservative leadership candidates have all said they would not hold a referendum on Britain's exit deal from the EU.
Work and pensions secretary Stephen Crabb, who campaigned for Remain, said the referendum was a "clear instruction to government" and there could be "no attempt to sidestep it".
Justice Secretary Michael Gove has said he would wait until at least 2017 to kick off the two-year process of negotiating the UK's withdrawal by invoking Article 50 of the Lisbon Treaty.
Home Secretary Theresa May, who is seen as the frontrunner, has said the government should not invoke Article 50 before the end of the year.
But energy minister Andrea Leadsom says it should be triggered as quickly as possible, to remove economic uncertainty.
In an interview with the Sunday Telegraph, former defence secretary Liam Fox pencilled in a date when the UK would leave the EU - 1 January 2019.
Mr Blair was also asked about immigration and the Labour leadership crisis on The World This Weekend.
He said there was not much more the UK could achieve by being out of the EU than it could from within and that it should explore options for what could be done without "having to eject ourselves from the entirety of the European Union".
But he said: "Even if you apply an Australian points system to European migration, you are going to get European migrants."
He would not be drawn into the debate over whether Jeremy Corbyn should stay or go as Labour leader, but said: "We have to have an opposition that holds the government to account."
Meanwhile, the former prime minister refused to comment on the long-awaited public inquiry into the Iraq War, which will be published on Wednesday.
The Chilcot report was launched in 2009 into the UK's participation in the US-led invasion of Iraq in 2003 - which led to the toppling of Saddam Hussein.
There have been calls for Mr Blair to apologise for his role in leading Britain into the war, in which 179 British service personnel were killed.
"I know why you have to ask me, and I hope you understand why, having spent several years saying I will wait for the report, I will actually wait for the report," he told the BBC.
Labour's John McDonnell also said he would not comment until the report was published - but refused to rule out calling for Mr Blair to be tried for war crimes over Iraq.
Former Scottish First Minister Alex Salmond said many MPs were "absolutely determined that account has to be held".
He said those MPs believed "you cannot have a situation where this country blunders into an illegal war with the appalling consequences" without "a judicial or political reckoning for that".

Ex Output:
Former prime minister Tony Blair has said "we should keep our options open" on the UK leaving the European Union.

He made his appeal while celebrating Mass in three native languages after a new Vatican decree approved their use.
The Pope also used the open-air service in San Cristobal de las Casas to warn about threats to the environment.
Throughout his five-day trip he has condemned the evils of forced emigration and drugs.
He has urged Mexico's leaders to provide "true justice" to suffering citizens.
But on Monday he drew attention to the suffering of indigenous people in his address in Chiapas state.
"On many occasions, in a systematic and organised way, your people have been misunderstood and excluded from society," the 79-year-old pontiff said after citing Popol Vuh, an ancient Mayan text.
"Some have considered your values, culture and traditions to be inferior. Others, intoxicated by power, money and market trends, have stolen your lands or contaminated them. How sad this is," he said.
"How worthwhile it would be for each of us to examine our conscience and  learn to say, 'Forgive me!'"
Correspondents say that while Chiapas is the country's least Roman Catholic state, tens of thousands of people attended an open-air Mass in a sports field in San Cristobal de las Casas.
Women wore colourfully embroidered dresses to deliver biblical readings and hymns in the Chol, Tzotzil and Tzeltal languages.
The pontiff highlighted the deep appreciation of indigenous people for nature and said their community had much to teach the rest of the world.
He also highlighted the need to care for the environment.
"We can no longer remain silent before one of the greatest environmental crises in world history," he said,
While Mexico is the world's second most populous Catholic nation after Brazil, only 58% are loyal to the Vatican in Chiapas in comparison to 82% in the rest of the country.
Mexicans hope papal visit brings change
On Tuesday, the Pope heads to the capital of the western state of Michoacan, a region scarred by drug violence.
The Pope concludes his five-day trip in Ciudad Juarez on the US border, a city which has also been blighted by drug-related murders. A Mass there will highlight the plight of migrants.

Ex Output:
Pope Francis has asked Mexican indigenous people in Chiapas state for forgiveness over they way they have been excluded from society.


Ex Input:
Most of those in the group drive tankers of petrol, diesel or kerosene to and from Maiduguri - the city at the heart of the Islamist insurgency in the north-east and the capital of Borno state.
Gathered at the Ogere Trailer Park, about 50km (30 miles) north of Lagos, they say they have all been affected by the six-year conflict.
"We are all concerned about the situation, we have all lost relatives, wives and children are kidnapped and houses have been burnt," says Atiku Abubakar.
Speaking in Hausa, he and his colleagues describe the perils of the route to and from Lagos.
It takes two and a half days when a tanker is empty and four and a half days when full.
They say it is dangerous enough without the militants to contend with as there are so many potholes.
"Ten of my colleagues who ply this route have been killed in the last three weeks," says Mr Abubakar.
"The militants stopped them and cut off their heads with an electric chainsaw and burned the trucks," he says.
"Boko Haram is usually only interested in commandeering smaller vehicles, sometimes the fighters will take the lorries, but most of the time they burn them."
Another truck driver chips in to say that if a driver looks "powerful" he may be kidnapped and conscripted as a fighter, but anyone looking "weak" will definitely "lose his head".
"If you reach Damaturu by five in the afternoon, you dare not continue on the final leg to Maiduguri," he says, explaining that a driver may not manage the last 130km before the sun sets, when they would be most vulnerable to attack.
The drivers tend to work for an owner who has about 20 tankers - each vehicle also has about two assistants to help with loading and guarding the cargo, known as motor boys.
As the drivers and motor boys ease into the conversation they begin to open up about how the insurgency has directly affected them.
Driver Trap Bukar says he was in the town of Bama when it was captured by Boko Haram last September.
"It started early in the morning. Suddenly they came. There was shooting, in my presence I saw four people go down; the soldiers fled," he says.
He lifts up his shirt to show what look like bullet scars on his upper torso
"I could tell you many unhappy tales," he says, with tears in his eyes.
But he suddenly gets up and leaves the group and his colleagues say he is too traumatised by his memories to continue.
Kullima Ali, 18, who has been a motor boy for four years, says he is now his family's only bread winner.
He says it is very difficult to tell the militants from soldiers, as they dress in camouflage - with only their eyes visible.
"They stole some food, killed my two brothers and burned our house in Maiduguri in January 2013," he says.
"There's only my mother and my sister now."
He says he had wanted to go and study science, but he is unable to afford to continue his education.
"Many of the drivers have good qualifications," says Umar Hussaini, 18, a motor boy who helps his driver brother.
He introduces me to Ibrahim Abdullahi, 25, a former university student who had been studying civil engineering at the start of insurgency.
He has been working as a trucker for the last five years as there are few other employment opportunities for young men, especially in the areas affected by the conflict.
"Yes I am scared, if there was other work I would find another job," says Mr Abdullahi.
All the truckers express anger about the six-week postponement of the 14 February presidential election and are vocal in their criticism of President Goodluck Jonathan's handling of the conflict.
Some even refer to him as "the chairman of Boko Haram" - seeing him as complicit in the group's growth over the years.
Others say his complicity lies in his neglect of north-east.
"President Jonathan is just as guilty as those Boko Haram killers because he has chopped off all the money to repair the roads," Mr Abubakar says.
Life is now a constant financial struggle for them, he adds.
For each trip, a driver gets a 10,000 naira ($50, Â£33) living allowance but this might have to last for several weeks as he waits at Ogere Trailer Park for clearance to go into Lagos port to collect cargo.
Most of the truckers get a monthly salary of between $100 and $200 and the motor boys receive $2.50 a day.
Saleh Mohamed, a driver who has just arrived back from Lagos port with his shipment of petrol, sits down with the group under the porch looking exhausted.
"I spent four days in the queue in the traffic to the port - I haven't slept for four nights because I had to watch out for thieves as they remove parts from the vehicle or steal the gas," he says.
But he is only taking a short break of a couple of hours as he is anxious to put the coming dangers behind him.
"The killings are too much and have been going on for too long," says his colleague Mr Abubakar.
"President Jonathan is not doing anything. We hope he will leave - we want change."
