As Roberto Azevedo leaves the World Trade Organization today, the institution faces multiple crises without a captain - a situation experts warn could drag on for months.
Any future WTO leader will head an organisation mired in stalled trade talks and struggling to curb trade tensions between the US and China.
It must also help member countries navigate a devastating global economic slump sparked by the coronavirus pandemic.
The global trade body faces relentless attacks from Washington, which has crippled the WTO dispute settlement appeal system and threatened to leave altogether.
Many observers fear that intransigent US positions could paralyse the WTO process of designating a new director general, leaving the organisation leaderless for the foreseeable future.
"The US demands that the new DG shares US concerns, many of which are about addressing concerns related to China," Manfred Elsig, a professor of international relations at the World Trade Institute in Bern told AFP.
"Given that the DG is chosen by consensus, this tough stance complicates the selection," he added.
The WTO has already presented a timeline for selecting one of eight candidates in the running to replace Azevedo within a few months.
But Elsig warned that "the process is already torpedoed.
"It could well be that many WTO members want to wait until after the (US) election, hoping that the administration changes."
Azevedo's surprise announcement in May that he would end his second WTO term 12 months early forced the organisation to speed up its usually lengthy process of selecting a new leader.
Ireland's recently resigned EU Commissioner Phil Hogan pulled out of the race some months ago, although he never formally declared his candidacy.
The organisation is due next month to begin three rounds of consultations in which all member states confidentially voice their preferences, gradually whittling down the list.
The process, based on consensus, is expected to last until mid-November.
But soaring international tensions and growing politicisation of picks to head UN agencies and other international organisations could trip up the tentative timeline.
Members failed last month to pick an acting chief from among four deputy directors - something that is normally a straightforward process.
Brussels and Washington butted heads over whether German Karl Brauner, or American Alan Wolff, should get the job, in what observers say was unprecedented politicisation of an administrative decision.
The candidates themselves appear to be taking the turmoil in stride.
"I have confidence in the selection process and look forward to this concluding in good time," Liam Fox of Britain told AFP in an email.
Kenyan candidate Amina Mohamed insisted in an interview that she saw "no reason to doubt that the timetable (announced for the selection process) won't be realised."
Many say the process has never been so politicised, and some suggest the organisation might be forced to ditch its long-held policy of consensus and ask members to vote.
That would mark a big shift. In 1999, when members were unable to unanimously choose who should be given four years at the helm, they opted to hand the two top picks a three-year mandate each instead of resorting to a vote.
But professor Elsig said such a decision would be unfortunate in the current climate.
"Someone with a short three-year tenure might likely be perceived as a lame duck from the beginning," he stated.
