Currency fluctuations affect international pricing strategies by influencing input costs, revenue conversion rates, trade competitiveness, and profit margins across global markets. Multinational companies must continuously adjust pricing to reflect exchange rate volatility, inflation differentials, hedging instruments, and regional purchasing power. This paper investigates cross-market pricing dynamics through international finance theory, exchange rate pass-through (ERPT), purchasing power parity (PPP), and cost-plus vs. value-based pricing frameworks. The proposed Currency-Market Pricing Adjustment Model (CMPAM) evaluates how firms respond to exchange rate movements via hedging, local pricing, dynamic adjustment algorithms, and supply chain restructuring. Findings emphasize the strategic importance of real-time pricing automation, local currency billing, and hybrid hedging structures.
