Geopolitical and Supply Chain Tensions (2024–2025): 
Export restrictions from key cobalt-producing regions such as the Democratic Republic of Congo, as well as ongoing logistical challenges, caused significant supply shocks. Cobalt prices rebounded sharply after hitting a nine-year low, and cobalt oxide pigment blue prices followed this volatility. Downstream buyers, facing high prices and low inventories, delayed purchases, which further tightened the market and contributed to price spikes. 
Strategic Supply Constraints and Quotation Suspensions (2025): 
In 2025, several major cobalt oxide pigment producers suspended spot price quotations and deliberately restricted shipments, prioritizing long-term contract customers. This artificial scarcity, combined with already low inventories in downstream sectors and a resurgence in demand from battery and pigment industries, led to a sharp price increase of 4.5–5%. Transaction volumes dropped by approximately 70%, and negotiation periods lengthened, reflecting heightened market uncertainty and volatility. 
COVID-19 Pandemic (2020): 
The onset of the COVID-19 pandemic led to major disruptions in global supply chains, directly affecting the availability of raw cobalt and the production of cobalt oxide pigments. As key industries such as ceramics, automotive, and pigments slowed due to lockdowns and economic uncertainty, demand for cobalt oxide pigment blue declined, resulting in softer prices. Towards the end of 2020, as global economies began to recover and industries reopened, demand stabilized, and prices began to recover. 
These events highlight the cobalt oxide pigment blue market’s sensitivity to supply-side disruptions, producer strategies, and shifting global demand. The market remains vulnerable to both macroeconomic shocks and targeted actions by major suppliers.
