How Price Shocks Change Resource-Dependent Economies: The Commodity Curse.
Farmers in Cote d’Ivoire and Ghana ought to have been celebrating when cocoa prices went above 12,000 metric tons in late 2024, a sixfold increase of the historical range of trading. In its place, most people were unable to even get the beans under their production. Sick trees, old age plantations and old underinvestment ensured that supply was not responsive to demand. Several months later prices plummeted almost as much as they had previously soared and producers, governments and manufacturers of chocolate all over the world found themselves scrambling to cope.
This is what a commodity price shock is all about: bloody volatility that can destroy or salvage even whole economies in a few months, and which is not in the control of the very nations that rely on it.
The Anatomy of Dependency
Commodity-dependent economies are characterized by the fact of a sharp reality that they receive more than 60% of their export earnings through a single resource . In Sub-Saharan Africa, 31 nations in the category are dependent on agricultural commodities, 6 on energy, as well as 14 on minerals and metal ores. These countries are price takers in the international markets their economies dependent on the trading floors in London, Chicago as well as Shanghai.
It is a structural vulnerability. With the increase in commodity prices, the government coffers are filled, foreign exchange reserves grow and the economic growth increases. The opposite occurs with savage velocity when prices go down, and budgets collapse, currencies devalue and development projects go as far as stop. The asymmetry forms a boom-bust cycle that is very hard to come out of.
The Transmission Mechanisms: Shocks-Transmission in an Economy.
Price shocks of commodities spread in a cascading manner with each channel enhancing the other.
The most direct is fiscal transmission. The fiscal policy in commodity-exporting emerging economies is less procyclical and more volatile than amongst non-commodity-dependent counterparts by a factor of 30 and 40, respectively. In booms, governments are lavish, creating jobs in the government, and initiating infrastructure projects. In case of crash in prices, revenues reduce, and expenditures are hard to cut in a political context. The outcome is the swelling deficits, borrowing and subsequent austerity.
A study conducted in 44 African countries shows that commodity price volatility has a huge impact on lowering the efficiency of government expenditure. It is more beneficial to countries that have sovereign wealth funds; the latter do not have them, which makes them highly susceptible. The transmission channels identified are inflation, political stability, workforce dynamics, and income inequalities- each having different impacts on the effectiveness with which public resources are allocated.
The mechanism of transmission of macroeconomics is using the exchange rates and inflation. Price boom usually makes the domestic currency stronger, rendering other export industries less competitive- the modern day Dutch disease. The opposite effect is observed in a price crash, which initiates depreciation which increases the price of imports including the necessities such as food and fuel. This can translate to instant suffering to common citizens as it is the case with developing countries.
Sectoral transmission has an impact on producers. The Kenyan fertilizer crisis of 2020-2022 demonstrates how global shocks do not transfer homogenously through the local markets. At the time of doubling the international fertilizer prices, the retail prices in Kenya increased by an average of 81 percent without any significant deviations, with a minimum of 5 percent price drops and the highest of 138 percent changes in various stores. Larger stores and large agricultural areas had a quicker transmission of prices and the high-poverty areas had partial insulation but slower to gain in case of falling prices. It was a very pronounced asymmetry: a rise in imports led to more rapid price adjustments than a fall.
The Agricultural Commodity Channel: Global Markets to Local Tables.
In the case of food-importing developing countries, the effect of the commodity price shocks passes directly to the welfare of households. A study in 2024 which analysed the price transmission of four large cereals i.e. maize, rice, sorghum, and wheat in 23 emerging economies revealed that all commodities except sorghum had a relatively strong transmission elasticity. More importantly, the spread of shocks was almost instantaneous, and total absorption, in two to three months.
This implies that once international grain prices skyrocket, the local food prices come along. This is not an abstract economic indicator to the household that is spending half or more of its income on food, but it is the difference between sufficient nutrition and starvation.
Cocoa Case Study: The Storm of the Century.
The cocoa price explosion of 2023-2025 demonstrates literally all the aspects of the dynamics of commodity shock.
Systemic fragility was generated by the concentration of supply. More than 70 per cent of the world cocoa comes out of West Africa, with Cote d'Ivoire and Ghana contributing about 60 per cent. Hit by a combination of bad weather, illness, and building dilapidation at the same time, the global production in 2023-24 season, down to 4.2 million metric tons, dropped 14% in 2023-24, the season when 4.9 million was recorded in 2023.
The shock was increased by structural degradation. The decades of poor investments had resulted in old trees, widespread cases of Cacao Swollen Shoot Virus and agricultural communities unprepared to act. In comparison to weather cycles, viral disease is structurally destructive, that is, infected trees must be dug up and replaced, and this takes years.
The amplification was increased financially. The shortage of supply was noticed by the speculators who stacked long positions. By the first quarter of 2024, more than 60 percent of future contracts were held by non-commercial investors. With the increase in pricing, the margin requirements increased and processors were left with no choice but to decrease forward cover as well, further suppressing hedged supply and causing fed price panic.
This was eventually followed by demand destruction. Chocolate manufacturers improved products, making them less intense in cocoa at $12,000 per ton. Grinding capacity declined. The consumers also experienced shrinkflation, that is, smaller bars at the same price. Large confectionaries such as Mondelez anticipated huge revenues decline directly reliant on cocoa expenses.
At the end of the first half of 2025, the situation with supply had improved. It was predicted to be 4.84 million metric tons in the 2024/25 season, or increase of 8 percent per year. The prices fell by 40-45 percent on their peaks. With scathing speed the market changed to a pricing crisis to a pricing recovery.
The most important question is whether cocoa will go back to its former range that existed before 2023. Evidence suggests not. The cost of production has been repriced irreparably. The supply of West Africa is weak. The structural adjustment of demand has been changed. The medium-term equilibrium at an estimated level of $6,000 per ton seems to be three times historic but half the peak.
Empirical Evidence: What The Data Say.
Both risks and complexity of commodity dependence is proven by thorough analysis. In a 2024 study of 31 countries in Sub-Saharan Africa based on Vector Error Correction Models generated three consistent results in agricultural, energy and mineral commodity categories:
To begin with, the dependence on commodities has a positive correlation long-run economic growth--increased prices do positively impact resource-rich economies.
Second, the volatility of commodity prices is found to be inversely related to economic growth- volatility in itself regardless of price levels is not conducive to growth.
Third, there is a positive correlation between commodity dependence and commodity price volatility the more a country depends on one commodity the more it is exposed to price fluctuations.
