Intervention analysis of COVID-19 pandemic impact on timber price in selected markets

Using intervention analysis and time series of roundwood prices from ten European and North American countries, we analyzed the impact of the COVID-19 pandemic on the movement of timber prices. The study material consists of forty-six quarterly time series prices of logs and pulp, both softwood and hardwood, covering the period 2005-2022. During the Covid-19 pandemic period (2020:Q1-2020:Q4), softwood log prices mostly underwent declines, with the changes being the largest in Slovakia (-35%), the Czech Republic (-24%) and Austria (-24%), slightly smaller in the United States (-19%), Poland (-17%), Slovenia (-12%) and Germany (- 11%) while no significant price changes were recorded in Finland and Sweden. In Canada and the United States, sharp price declines occurred earlier (2020:Q1 and 2020:Q2, respectively), while in Europe, significant price declines occurred later and lasted longer. In the post-pandemic COVID-19 period, prices increased, but in most cases, the shift was not statistically significant compared to the pre-pandemic period. Softwood pulp prices were subject to much less change, with a significant increase only in Slovakia and Poland. In contrast, no significant changes were observed in the price of both log and pulpwood hardwood during the COVID-19 pandemic.
