Interest Rate Differentials: The difference between the Bank of England's (BoE) interest rates and the Central Bank of Tanzania's (BoT) rates influences capital flows. Higher rates in the UK tend to attract investment, strengthening GBP.

Economic Growth: UK and Tanzanian economic performance impacts currency values. Stronger UK growth typically boosts GBP, while robust Tanzanian growth can support TZS.

Inflation: UK and Tanzanian inflation rates affect purchasing power and currency value. Higher UK inflation can weaken GBP if not managed effectively.

Political Stability: Political stability or instability in both countries can affect investor confidence and currency values. Uncertainty tends to weaken the affected currency.

Commodity Prices: Tanzania's export earnings from commodities like gold impact TZS. Higher prices can strengthen the TZS.

Global Risk Sentiment: Global risk appetite influences demand for safe-haven currencies. During crises, GBP may benefit from safe-haven flows.

Trade Balance: The UK and Tanzania's trade balances influence currency demand. A UK trade surplus may strengthen GBP, while a Tanzanian surplus supports TZS.
