Ghana’s industrial sector is facing an intense dual squeeze of escalating production expenses and a volatile global supply chain.
New data has revealed a steep spike in the country’s Producer Price Inflation (PPI). Simultaneously, industrial players and government officials are sounding alarms over the soaring costs of building infrastructure, demanding an aggressive pivot toward domestic raw materials to salvage the manufacturing and construction sectors.
According to the latest figures released by the Ghana Statistical Service (GSS), annual producer inflation climbed sharply to 5.8 percent in May 2026, up from 2.7% recorded in April. This metric indicates that, on average, domestic producers received 5.8% more for their goods and services compared to the same period last year.
The primary catalyst behind this spike was the mining and quarrying sector, which registered an inflation rate of 11.0% in May. The rebound was also heavily driven by recoveries in transport and storage, which vaulted from a negative 6.6% in April to a positive 7.7% in May, alongside manufacturing, which recovered to 0.7% from negative 0.7%.
While annual indicators suggest renewed cost pressures at the factory gate, the GSS reported a minor silver lining: producer prices actually declined by 1.4% on a month-on-month basis between April and May 2026. Because PPI acts as a leading indicator for retail markets, experts warn that these overarching annual production increases are bound to trickle down to everyday consumers through higher retail prices.
The Clinker Crisis: The True Culprit in Housing Costs
Nowhere are these upstream production cost pressures more visible than in the domestic building sector. Speaking at the INTERCEM Africa 2026 conference in Accra, industry leaders revealed that Ghana’s reliance on imported clinker the foundational component used to bind cement is heavily draining local industries due to global shocks, port congestion, and volatile fuel prices.
Frederic Albrecht, Chairman of the Chamber of Cement Manufacturers, Ghana (COCMAG) and CEO of CBI Ghana, explained the structural challenges pinning down local operations:
“Clinker production is not possible in Ghana because of unsuitable limestone deposits. Yet clinker remains a major input in cement production, and importing it is increasingly expensive due to rising fuel costs, port congestion, and global supply disruptions.”
Albrecht emphasized that clinker production is uniquely exposed to global energy markets, requiring processing temperatures of up to 1,500 degrees Celsius. To protect the economy from exchange rate pressures and price volatility, he stressed that alternative local formulas are no longer optional:
“We must develop a different type of cement that allows Ghana to become more self-sufficient. By reducing clinker ratios and utilising local raw materials, we can lower production costs, improve competitiveness, and reduce pressure on foreign exchange.”
State Demands Innovation: Shift to Clay and Limestone Alternatives
The government has echoed this sentiment, warning that the state’s massive industrialization and housing projects will continue to demand massive quantities of cement, making imported supply lines unsustainable.
The Minister for Trade, Agribusiness and Industry, Elizabeth Ofosu-Adjare, issued a direct charge to manufacturers to prioritize local inputs like clay and specialized limestone variations to make development cost-effective:
“Our cement industry must become more affordable, accessible, and sustainable. We must reduce clinker imports and invest in local raw material production. There are significant local resources that can be harnessed.”
The Minister pointed to early progress in Limestone Calcined Clay Cement (LC3) by domestic leaders as proof that the shift is viable.
“The example set by CBI and Ghacem shows that this transformation is achievable. We expect more companies to replicate these efforts to reduce clinker usage in our building projects. Whether we like it or not, Ghana’s development will require more cement. However, we must produce it in an eco-friendly manner by reducing clinker imports and promoting import substitution.”
A Three-Year Horizon for True Transformation
Despite the consensus on utilizing local raw materials to ease macro-inflationary burdens, reversing decades of import dependency will require significant structural adjustments. Transitioning to low-clinker options requires heavy capitalization and long-term infrastructure upgrades.
“Establishing alternative production systems takes about three years,” Albrecht noted, calling for proactive planning. “It requires foresight, investment, and strong collaboration between industry players and government.”
Adding to this sentiment, Bishop Dr. George Dawson-Ahmoah, CEO of COCMAG, highlighted the immediate benefit of international knowledge-sharing platforms to speed up this transition:
“This conference provides a valuable platform for innovation and collaboration. It is helping Ghana’s cement producers adopt more sustainable practices, including the use of clay and other local materials to reduce clinker dependency.”
With macro-level factory gate inflation climbing back up to 5.8%, policymakers and corporate leaders recognize that shielding households from soaring retail costs requires reshaping the basic supply lines of the Ghanaian industrial sector.
