October 12, 2021 GBM THE US MARKET: AN OPPORTUNITY FOR MEXICO • • • The ceramic tiles market in the United States is yet to fully recover from the housing bubble, as the consumption of ceramics has remained flat for the past 16 years. The market began to improve after the crisis until the COVID-19 pandemic emerged. However, with home office mandates increasingly becoming an option for some American families in the context of a healthy housing market, with low levels of inventory and easy access to mortgages, we believe demand for ceramic tiles is poised to keep rising. The domestic production deficit for ceramics in the United States may open an opportunity to increase Mexican imports and expand the supply in the world's largest ceramic importer. Given that imports account for 70% of the US consumption, Mexico's privileged geographic position may allow it to keep gaining market-Mexico accounted for -17% of US imports in 2020.
