Market-related risks in Iran’s pharmaceutical sector are shaped by the interaction of regulatory constraints and macro-financial conditions, which together create structurally embedded financial pressures. Although existing studies have highlighted the role of pricing regulation and market volatility in pharmaceutical industries (
25,
27), the findings of this study indicate that, in Iran, these risks operate in an interconnected manner and reinforce one another rather than acting independently. A central finding concerns the role of pricing mechanisms as a key transmission channel of financial risk. Consistent with prior evidence, rigid and non-transparent pricing systems create misalignment between regulated prices and actual production costs. However, the results of this study show that these distortions extend beyond margin compression and trigger a broader set of firm-level responses, including stock-keeping unit reduction, quality adjustments, cross-subsidization through over-the-counter products, and tightening of distributor credit (
27). This study advances the literature by demonstrating how pricing risk acts as a central transmission channel: it intensifies liquidity stress, magnifies exchange-rate exposure, and suppresses investment capacity. Strengthening pricing governance with transparent methodologies and predictable revision cycles is therefore essential for restoring financial viability (
14,
27). The findings show that interest-rate risk functions as a significant amplifier of liquidity strain and investment decline. Borrowing costs consistently exceeded operating margins, while unpredictable policy-driven rate shifts increased real repayment burdens, consistent with evidence from capital-intensive regulated sectors (
28). Delayed payments from insurers (6 - 12 months) forced firms to rely on costly short-term credit or accelerate receivable discounting, tightening rollover risks and elevating default probability, in line with weaknesses in public financial management reported internationally (
6). Strategically, firms postponed innovation, halted expansion projects, and shifted toward short-termism, reinforcing global concerns that sustained financial pressure diminishes competitiveness (
28,
29). These findings underscore the need for sector-level reforms to stabilize financing channels and improve payment discipline (
30,
31). Exchange-rate volatility emerged as one of the most pervasive structural risks. Heavy reliance on imported active ingredients, fragmented FX allocation policies, and multi-rate currency regimes prevented cost forecasting, widened the gap between real expenditures and administered prices, and deepened liquidity risks, consistent with the global literature (
32). The study identifies how FX shocks propagate across subsystems, including rising working-capital requirements, erosion of operating margins, increased safety-stock needs, and declining trust from foreign suppliers. These cascading effects mirror international evidence linking currency risk to innovation decline and medicine shortages. In this context, FX exposure is not merely a market risk but a systemic amplifier of financial fragility. Unlike mature pharmaceutical markets that rely on structured credit infrastructures and clearly defined market-maker roles, the Iranian system lacks a legal, regulatory, or operational framework for such functions. This study demonstrates that the resulting institutional vacuum creates a structurally “orphaned” liquidity-stabilization function, leaving suppliers, manufacturers, and distributors exposed to cascading payment delays. Without mechanisms such as clearing platforms, enforceable settlement timelines, or structured discounting systems, liquidity traps intensify, echoing evidence on weak financial-governance environments in health systems (
6). This finding highlights a previously undocumented governance gap that contributes to systemic fragility. Competitive risk was driven not by market rivalry but by structural asymmetries, including preferential access to FX, licensing, or distribution opportunities for certain state-affiliated firms. Excessive fragmentation among small generic producers, destructive discounting, and opaque commercial practices further distorted incentives, echoing patterns seen in rent-seeking or price-based markets (
33,
34). These dynamics suppressed innovation investment and heightened supply volatility. Mitigation requires reinforcing competitive neutrality and establishing transparent regulatory oversight (
