Sudan's army-aligned government has issued new banknotes in areas it controls, causing long queues at banks, disrupting trade and entrenching division.
In a country already grappling with war and famine, the swap replaced 500 and 1,000 Sudanese pound banknotes (worth around $0.25 and $0.50 respectively) with new ones in seven states.
The government justified the move as necessary to "protect the national economy and combat criminal counterfeiters,” AFP reported.
But for many Sudanese it just caused problems.
In Port Sudan, now the de facto capital, frustration boiled over as banks failed to provide enough new notes.
One 37-year-old woman spent days unsuccessfully trying to get the new money.
"I've been going to the bank four or five times a week to get the new currency. But there is none," she told AFP, requesting anonymity for fear of reprisals.
Grocers, rickshaw drivers, petrol stations and small shop owners are refusing to accept the old currency, preventing many transactions in a country reliant on cash.
"We cannot buy small things from street vendors any more or transport around the city because they refuse the old currency," the woman said.
The currency shift comes 21 months into a war that has devastated the northeast African country's economy and infrastructure, caused famine in some areas, uprooted millions of people and seen the Sudanese pound plunge.
From 500 pounds to the US dollar in April 2023, it now oscillates between 2,000 and 2,500.
Finance Minister Gibril Ibrahim defended the switch, saying it aims to "move money into the banking system, ensure the monetary mass enters formal channels as well as prevent counterfeiting and looted funds.”
But analysts say it is less about economics and more about gaining the upper hand in the war between army chief Abdel Fattah al-Burhan and his former deputy Mohamed Hamdan Daglo, who leads the Rapid Support Forces (RSF).
"The army is trying to weaken the RSF by having a more dominant currency," Matthew Sterling Benson at the London School of Economics and Political Science told AFP.
After the RSF looted banks, the army "wants to control the flow of money" and deprive them of resources, he said.
Kholood Khair, founder of think tank Confluence Advisory, believes that this financial squeeze may accelerate RSF plans to establish a rival currency and administration.
"The move has catalyzed the already existing trajectory towards a split," she told AFP.
Sudan is already fragmented: the army holds the north and east and the RSF dominates in the western Darfur region and parts of the south and center.
Greater Khartoum is carved up between them.
For Sudan's population, the move has only compounded their suffering.
Activist Nazik Kabalo, who has coordinated aid in several areas, said supply chains have been severely disrupted.
Farmers, traders and food suppliers rely entirely on cash.
"And if you do not have cash, you cannot buy supplies, needed for aid or for anything else," Kabalo told AFP.
The government has promoted digital banking apps such as Bankak, but many Sudanese cannot access them because of widespread telecommunications outages.
