Carney and Draghi both started in academia, built their resumes at Goldman Sachs and finance ministries, and eventually rose to the top of the central banks in Canada and Italy -- before going further still. Each has chaired the Financial Stability Board, set up after the crisis to aid international banking regulation.
They both know how to make an entrance.
Within six weeks of starting his job in Frankfurt's Eurotower in November 2011, Draghi reversed two interest-rate increases engineered by Jean-Claude Trichet -- very much like Carney, who slashed borrowing costs some four and a half weeks into his term. At the Bank of Canada he popularized forward guidance, a tool central banks adopted widely after they had exhausting interest rates and asset purchases.
Language is also Draghi's legacy. "Whatever it takes." Three words that put a stop to speculation against the euro in 2012. The pledge caught most of his ECB peers by surprise because no plan was in place to underpin its credibility.
Both men drew praise for their responses to crisis, and Carney's role in preventing a recession in Canada earned him the move to Britain in July 2013. As Draghi defended his bond purchase program against governments, academia and the public, the Canadian was in charge of expanding the BOE's role in financial stability. He upped its staff considerably, while also navigating the Scottish and EU referendums and two general elections.
"Draghi and Carney are extraordinary technocrats who deeply understand the theory and process of central banking,'' said Nathan Sheets, former undersecretary for international affairs at the U.S. Treasury. They both have "a sixth sense as to how monetary policy fits into the broader political environment" that "really sets them apart."
Throughout their terms, they've wandered in and out of the political fray.
Draghi has been actively involved in shaping Europe's response in the worst moments of the crisis. But when Greece threatened to crash out of the euro 2015, he stayed in the background, stretching the rules of his own institution to keep money flowing to ensure it was governments' decision whether or not to pull the plug.
For his part, Carney faced repeated criticism for his role in the debate on the EU referendum, warning before the vote that a disruptive exit could spark a recession.
"It would be a good thing if the next Governor wasn't put in a position where they were drawn into politics as much," said David Miles, a former BOE policy maker.
Both chiefs forced their colleagues' hands by making announcements without consulting them. The ECB's quantitative-easing program came about after Draghi made public comments that left no room for alternatives.
Just after the 2016 referendum, Carney hinted at a loosening in monetary policy before meeting the rest of the committee. Two months later, policymakers unanimously voted to cut interest rates.
With Brexit, the BOE's star may now be waning while the ECB will be growing as new countries join.
"The ECB just by nature of its size and centrality will continue to be a major player,'' said former BOE policymaker Adam Posen. "Any form of Brexit at all will reduce" the U.K. central bank's status. "Its role is going to shrink hugely."
