Abstract

This study provides a novel insight into the influence of Cable News-Based Economic Policy Uncertainty (CNEPU) on market dynamics across stocks, crude oil, gold, and exchange rates. By emphasising media-driven policy uncertainty, it underscores the role of real-time news coverage in shaping public perception, investor sentiment, and subsequent market fluctuations. The study employs various quantile-based approaches using daily data from 2011 to 2023. The findings reveal distinct effects across asset classes: higher CNEPU stabilises stock market volatility (VIX) but amplifies crude oil volatility (OVX) under already volatile conditions. Gold volatility declines with rising CNEPU, reinforcing its role as a safe haven, while Euro currency volatility decreases, signalling a shift toward stability. Based on these findings, policy recommendations are provided.
