Underlying Asset Performance: 3LWP tracks an index of global government bonds. Bond price fluctuations due to interest rate changes, inflation expectations, and economic growth directly impact its value.

Supply and Demand: Higher demand for the ETF increases its price, while increased selling pressure lowers it. Market sentiment, investor risk appetite, and overall market conditions influence demand.

Interest Rates: Rising interest rates generally decrease bond prices, and therefore the ETF's price. Conversely, falling rates usually boost bond values.

Inflation: Higher inflation erodes the real value of bonds, often leading to price declines in the ETF. Lower inflation typically supports bond prices.

Currency Fluctuations: Since the ETF holds global bonds, changes in exchange rates between the GBP and other currencies can affect returns, and therefore the ETF price.

Credit Risk: Downgrades in the credit ratings of governments whose bonds are held by the ETF can negatively impact its price. Sovereign debt crises could also affect it.

Expense Ratio: While not directly impacting daily price changes, the ETF's annual management fee gradually reduces its overall returns, affecting its long-term value and influencing investor perception.

Liquidity: The ETF's trading volume and ease of buying or selling shares can influence its price, particularly during periods of market stress. Less liquid ETFs might experience wider bid-ask spreads.

Economic Growth: Strong economic growth might lead to expectations of higher interest rates, negatively impacting bond prices and the ETF. Slower growth could support bond prices.
