Abstract

fetched live from OpenAlex

This paper examines the dynamics of the foreign exchange market, focusing on the impact of macroeconomic, climate risk, and COVID-19 pandemic-related news on currency returns and volatility. Our findings show that prior to the pandemic, currency returns were mainly driven by macroeconomic news, but the onset of COVID-19 shifted attention to pandemic-related news. Vaccine-related announcements consistently increased volatility across markets, reflecting heightened uncertainty. Additionally, climate risk was found to strengthen the four major currencies relative to the US dollar. Finally, the study highlights context-specific effects, with certain indicators losing relevance while others gained prominence during the pandemic. • Climate risks lead to higher exchange rate volatility. • Countries with high exposure to climate change risks experience currency depreciation. • Before the pandemic, currency returns are primarily influenced by macroeconomic news. • The pandemic crisis shifted focus towards pandemic-related news.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
