Market Sentiment: Overall investor confidence and risk appetite impacts demand for UK-focused ETFs like 0RP9. Positive sentiment increases demand, driving the price up; negative sentiment does the opposite.

Underlying Index Performance: 0RP9 tracks the FTSE 100. Therefore, the performance of the companies within the FTSE 100 is a primary driver. Rising FTSE 100 indicates rising value of 0RP9.

Currency Fluctuations: The ETF is priced in GBP. Currency moves impacting UK assets will alter attractiveness of the ETF. A weaker pound relative to other currencies may cause the price to increase.

Interest Rate Changes: Interest rate rises by Bank of England could make UK stocks less appealing, impacting 0RP9 negatively. Lower rates may have the reverse effect, boosting demand and price.

Economic Data: Key UK economic indicators such as GDP growth, inflation, and unemployment data affect market sentiment and therefore 0RP9 prices. Stronger data increases prices, weaker data has the opposite effect.

Sector Performance: Specific sectors within the FTSE 100's performance can disproportionately influence 0RP9 if those sectors have large weightings in the index. Certain sector slumps would reduce the price, otherwise if there is a strong performance, there is an increase in price.

Dividend Yield: The dividend yield offered by the underlying assets in the FTSE 100 influences its attractiveness to income-seeking investors, directly affecting demand, and so affecting price if high yielding.

Supply and Demand: Basic economics applies. Higher demand than supply drives up the price, while higher supply and lower demand causes the price to decrease. ETF flows of purchase/sell will influence demand.
