Interest Rate Movements: Rising interest rates generally decrease bond prices, as new bonds offer higher yields, making existing bonds less attractive. Conversely, falling interest rates tend to increase bond prices.

Inflation Expectations: Higher inflation erodes the real value of future bond payments, reducing demand and pushing prices down. Lower inflation expectations can boost bond prices.

Credit Risk: Changes in the perceived creditworthiness of the bond issuer (France in this case) affect prices. Downgrades lower prices, while upgrades raise them.

Market Sentiment: General investor optimism or pessimism influences demand for bonds. Risk-averse investors often flock to government bonds, increasing demand and prices.

Economic Growth: Strong economic growth can lead to higher interest rates and inflation, negatively affecting bond prices. Slower growth might boost bond prices as investors seek safety.

Supply and Demand: Increased issuance of FR1M.GBOND bonds can increase supply and lower prices, while strong demand pushes prices higher.

Liquidity: More liquid bonds trade more easily and tend to have slightly higher prices compared to less liquid bonds.

Global Events: Major global events (political instability, pandemics, financial crises) can impact investor sentiment and influence demand for government bonds like FR1M.GBOND.
