Banking Fragility, Credit Allocation, and Private Sector Development in Algeria: Evidence from a Stock-Flow Consistent Financial Model
This paper employs a Stock-Flow Consistent macroeconomic model to demonstrate that Algeria's private sector underdevelopment stems from banking fragility and credit misallocation driven by state-directed lending, showing that credit liberalization and interest-rate reforms could significantly boost private investment and financial stability compared to maintaining current fiscal dominance.

Imagine the economy as a giant, complex plumbing system. In this system, money is the water, banks are the pipes and pumps, and businesses are the fields that need watering to grow. Usually, we think that if you have a lot of water (money) and a big network of pipes (banks), everything will flourish. But sometimes, the water gets stuck in the wrong place. It might pool up in a giant, empty reservoir owned by the government, while the private fields nearby are parched and dying. This is the puzzle of "financial repression." It's a fancy term for a situation where rules and habits force money to flow to the government or big state-owned companies, even when small, private businesses are the ones who could actually use it to build new things. Economists study this because when money gets stuck, the whole economy stops growing, jobs disappear, and innovation stalls.
Now, picture a researcher named Sid Ahmed Zenagui looking at a very specific, clogged-up plumbing system: Algeria's. For decades, Algeria has been rich in oil, which means the government has had plenty of cash. You'd think this would mean everyone gets rich and the economy booms. But Zenagui found a strange paradox: the banks are swimming in cash, yet private businesses can't get a loan to save their lives. To figure out why, Zenagui built a "Stock-Flow Consistent" (SFC) model. Think of this model not as a crystal ball, but as a super-accurate digital twin of the country's financial plumbing. It tracks every single dollar (or Dinar) as it moves from one pocket to another, ensuring that if someone has a dollar, someone else owes a dollar. This method is great for spotting where the water is getting trapped and why the pipes aren't working together.
Zenagui's digital twin revealed three main problems clogging the Algerian system. First, the government and state-owned companies are hogging the water. Because they have an "invisible guarantee" from the state, banks happily lend them money at low rates, effectively pushing private businesses out of the line. This is called "crowding out." Second, there is a "liquidity trap." The banks are sitting on a massive pile of extra cash—about 62 billion Dinar on average between 2000 and 2023—but they are too scared to lend it to private firms because of bad loans from the past and a lack of trust. It's like a water tower that is full to the brim, but the valves to the farms are rusted shut. Third, the system is fragile. Because so much money is tied up in risky loans to struggling state companies, the banks are sitting on a pile of "non-performing loans" (money that won't be paid back), which makes the whole system shaky.
To see how to fix this, Zenagui ran four different "what-if" scenarios on the digital twin, like testing different repair strategies.
- Scenario 1 (Credit Liberalisation): Imagine forcing the banks to stop giving free loans to the government and instead open the floodgates for private businesses. The simulation suggests this could boost private lending by 4.5 percentage points over five years.
- Scenario 2 (Interest Rate Reform): This involves letting the price of borrowing money (interest rates) be set by the market rather than the government. This was the most effective fix in the simulation, potentially raising private lending by 6.8 percentage points and boosting investment by 5.5 percentage points.
- Scenario 3 (Fiscal Dominance): This was the "do nothing" or "make it worse" scenario. If the government keeps printing money to pay its bills, the simulation showed that bad loans would pile up, private investment would shrink, and the economy would stagnate.
- Scenario 4 (Bank Restructuring): This involved cleaning up the bad loans and forcing banks to lend a specific amount to small businesses. This helped, but not as much as simply letting the market decide where the money goes.
The big takeaway from these simulations is that having a lot of money in the bank isn't enough; you have to let it flow to the right places. Zenagui's work suggests that if Algeria reforms how it sets interest rates and stops forcing banks to lend to the government, the private sector could finally get the water it needs to grow. However, the paper is careful to note that these are results from a computer model, not a guarantee of what will happen in real life. The model suggests that without fixing the government's spending habits, any attempt to open up the banks might just lead to more chaos. The study doesn't claim to have solved the problem, but it provides a clear, mathematically consistent map showing that the current way of doing things is keeping the economy dry, and that a few specific changes could turn the taps back on.
