East Africa's most populous country, already struggling with high inflation, became the third African state in as many years to default on its debt in December.

Ethiopia hasn't received any IMF funds since 2020 and its last lending arrangement with the fund went off track in 2021. The federal government and a rebellious regional authority signed a deal in late 2022 to end a two-year civil war.

The IMF, which said progress was made during its latest visit, has not said that currency reform is necessary for its support.

But the Fund usually favours flexible, market-determined exchange rates. Ethiopia has requested $3.5 billion of support from the IMF, sources told Reuters last year.

Chronic foreign currency shortages and a tightly controlled exchange rate has allowed a black market to flourish, on which the birr currently trades at between 117 and 120 per dollar, more than double the official rate of around 56.7.

"It seems that the Ethiopian authorities have found accepting the demands of the IMF hard," said Abdulmenan Mohammed, an Ethiopian economic analyst based in Britain.

"The Ethiopian authorities are worried about devaluation of the birr, (which) would have serious negative economic repercussions, including soaring inflation... and surging foreign currency denominated debts in terms of birr."

'Playing hardball'

In early 2021, Ethiopia requested a debt restructuring under the G20's Common Framework, a process established in response to the COVID-19 pandemic to bring in newer creditor countries like China and India. But progress was initially delayed by the civil war.

The country's external debt was $28.2 billion at the end of March, based on government data.

In August 2023, it secured a debt payments suspension from its largest bilateral creditor China, which from 2006 to 2022 committed to lending the country $14 billion, according to Boston University's Chinese Loans to Africa Database.

The rest of Ethiopia's bilateral creditors followed suit in December but said they could cancel the relief if Ethiopia did not get an IMF deal by March 31. When the deadline lapsed, it was extended to June 30.

There are widely varying estimates of the size of currency devaluation the IMF would accept, that could pave the way for a deal.

Irmgard Erasmus of research firm Oxford Economics said that she expects a weakening of 15 percent to coincide with an IMF staff-level deal on a bailout loan, a prerequisite for its external debt restructuring moving forwards.

"We retain the view that the IMF will require a good faith measure that solidifies Ethiopia's intent to implement a more flexible FX (foreign exchange) regime," she said in a note to clients. "(This) will set the scene for a series of stepwise devaluations on the path to FX liberalisation and monetary policy reform."

More than one currency adjustment is likely, the first between 30-50 percent, said Connor Vasey, a consultant at J.S. Held, pointing to Egypt, which devalued its pound 38 percent and secured a larger IMF loan in March.

The Ethiopians probably prefer a more gradual devaluation but have a weak negotiating position, Vasey said, after a previous IMF loan programme expired in 2021, amid the conflict and concerns about the country's ability to pay its debts.

"Ethiopia is coming into the meeting room with the IMF that is playing hardball and saying, 'You don't really have a foot to stand on, in terms of negotiating down our position,'" he said.

Nonetheless, Vasey said he expected Ethiopia to secure an IMF deal soon.

"There's an international push to get this all lined up. It's just a question of sequencing of the reforms," he said.

An IMF spokesperson pointed to comments made earlier this month by spokesperson Julie Kozack, who responded to direct questions on why Ethiopia did not secure a loan during the visit and whether it is likely to get one at the Fund's Spring Meetings next week in Washington DC.

"The team made substantial progress," she said. "These discussions are continuing and will continue at the upcoming Spring Meetings."

Ethiopian government officials did not respond to requests for comment. Authorities are committed to FX reform, state finance minister Eyob Tekalign told Reuters in October 2022.

"The exchange rate unification remains one important policy goal," he said at that time. "But we are just doing it gradually."
