**Underlying Index Performance**: The primary driver is the performance of the Solactive US Treasury Bond EUR Hedged index, which FRNE.F tracks. Positive index returns lead to higher ETF prices, and vice versa. **Interest Rate Movements**: Changes in US Treasury yields significantly impact bond values. Rising yields typically decrease bond prices, affecting FRNE.F negatively. **EUR/USD Exchange Rate Fluctuations**: The ETF is EUR-hedged, but the effectiveness of the hedge can vary. Fluctuations in the EUR/USD exchange rate can still indirectly affect the ETF's price if the hedge isn't perfect. **Market Sentiment**: Overall investor confidence and risk appetite influence demand for fixed-income assets. Risk-off sentiment can drive investors to bonds, increasing FRNE.F's price. **Supply and Demand**: The basic economic principle applies. High demand relative to supply pushes the price up, while increased supply relative to demand lowers the price. **ETF Management Fees**: The ongoing fees charged by the ETF provider reduce the overall return and can slightly affect the price compared to the underlying index performance.
