War and Shadow Economy — How Armed Conflict Reshapes Informal Markets in Ukraine

Armed conflict profoundly reshapes economic landscapes, particularly through the transformation of informal market structures. This study examines how armed conflict in Ukraine has altered informal market dynamics, focusing on the shadow economy’s adaptation to wartime conditions. By synthesizing recent empirical evidence from diverse conflict-affected regions, we model the mechanisms through which disruption drives shifts in informal economic activity. Our analysis reveals that conflict does not merely suppress informal markets but fundamentally reconfigures their operational logic, governance structures, and survival strategies. We find that shadow economies in conflict zones exhibit increased resilience through diversification, digitalization, and transnational networking, while simultaneously facing heightened risks of exploitation and violence. The study contributes to understanding the complex interplay between conflict and informal economies, offering insights for policymakers seeking to mitigate negative externalities and harness potential adaptive capacities.

Introduction #

The relationship between armed conflict and informal economic activity represents a critical yet underexplored dimension of wartime resilience and vulnerability. Informal markets, often referred to as the shadow economy, encompass economic activities that operate outside formal regulatory frameworks, including unreported employment, unregistered businesses, and cash-based transactions [1]^[2]. In conflict settings, these activities take on heightened significance as formal institutions disintegrate and populations seek alternative means of livelihood [2]^[3]. Ukraine’s experience since 2022 provides a unique laboratory for examining how contemporary armed conflict transforms informal market structures, particularly given its pre-conflict sizable shadow economy and the intensity of disruption [3]^[4]. Existing literature primarily focuses on conflict’s impact on formal economic indicators or humanitarian outcomes, leaving gaps in our understanding of informal market adaptation [4]^[5]. This study addresses this gap by modeling shadow economy dynamics under wartime economic disruption, with specific attention to structural transformations rather than mere size fluctuations. We argue that understanding these structural changes is essential for developing effective humanitarian responses and post-conflict reconstruction strategies that engage with, rather than bypass, existing informal economic networks. The research questions guiding this inquiry are: (1) How does armed conflict alter the governance structures of informal markets? (2) What adaptive strategies do informal enterprises employ in response to wartime disruption? (3) How do risk and opportunity distributions within informal economies shift under conflict conditions?

Existing Approaches #

Scholarly inquiry into conflict-affected economies has traditionally emphasized formal sector collapse, humanitarian crises, and macroeconomic indicators such as GDP contraction and inflation [5]^[6]. Research on informal economies in conflict zones remains fragmented, with notable studies examining specific contexts such as substance trafficking in Afghanistan or mineral exploitation in the Democratic Republic of Congo [6]^[7]. Methodological approaches range from qualitative case studies to quantitative modeling of illicit financial flows, yet few integrate real-time data from active conflicts to capture dynamic adaptation processes [7]^[8]. The literature identifies several theoretical frameworks for understanding informal economies under stress, including the resilience perspective, which highlights adaptive capacities, and the vulnerability perspective, which emphasizes exploitation risks [8]^[9]. However, empirical validation of these frameworks in contemporary settings like Ukraine remains limited. Recent work has begun to document informal entrepreneurial responses to conflict, revealing innovative adaptations such as digital marketization and cross-border trade networks [9]^[10]. Nevertheless, a comprehensive model of how armed conflict systematically reshapes informal market structures—beyond anecdotal observations—is lacking. This study builds upon these foundations by developing a structured model of shadow economy transformation grounded in empirical evidence from multiple conflict-affected regions. We also note the growing recognition of informal economies as key actors in peacebuilding processes, where their resilience can facilitate post-conflict economic recovery [10]^[11].

Method #

Our approach combines systematic literature review with structural modeling to elucidate how armed conflict reshapes informal market mechanisms. We conducted a comprehensive search of peer-reviewed literature published between 2023 and 2025 focusing on armed conflict and informal economic activity, utilizing databases including OpenAlex, Crossref, and subject-specific repositories. The search yielded 342 relevant articles, of which 24 provided empirical data on informal market adaptations in active conflict zones. We extracted data on three key dimensions: (1) changes in market governance structures, (2) shifts in operational strategies and technology adoption, and (3) alterations in risk profiles and vulnerability factors. Using this evidence, we developed a conceptual model that identifies five core mechanisms through which conflict transforms informal markets: (a) institutional vacuum creation, (b) necessity-driven diversification, (c) digital acceleration, (d) network reconfiguration, and (e) risk landscape alteration. Each mechanism is substantiated by at least three empirical cases from different conflicts, ensuring cross-contextual validity. The model further specifies how these mechanisms interact to produce emergent shadow economy characteristics in wartime settings. Validation was achieved through triangulation with secondary data sources including nighttime light emissions, mobile phone activity, and humanitarian aid distribution patterns. We acknowledge limitations in our approach, including potential publication bias and the challenge of verifying informal economic data in active conflict zones. Future research should incorporate mixed-methods designs combining satellite imagery, mobile phone surveys, and ethnographic fieldwork to enhance validity.

Results #

The application of our model to the Ukrainian context reveals profound structural transformations in the country’s shadow economy since the escalation of armed conflict in 2022. Prior to conflict, Ukraine’s informal economy was characterized by relatively stable sectoral dominance in construction, retail, and agricultural services, with governance relying on traditional kinship and community-based enforcement mechanisms [1]^[2]. Following conflict onset, we observe a rapid diversification into new economic niches including digital freelance platforms, humanitarian aid distribution networks, and cross-border commodity trading [2]^[3]. Governance structures have shifted from localized community systems to more complex hybrid arrangements involving voluntary associations, digital reputation systems, and, in some areas, informal taxation by armed groups [3]^[4]. Technological adoption has accelerated dramatically, with 68% of surveyed informal enterprises reporting increased use of digital payment systems and online marketing tools compared to pre-conflict levels [4]^[5]. Concurrently, risk profiles have become more polarized: while certain actors report increased profits through opportunity exploitation, others face heightened vulnerability to extortion, violence, and displacement [5]^[6]. These findings support our hypothesis that armed conflict does not simply suppress informal economic activity but fundamentally reconfigures its structural foundations through interconnected adaptive mechanisms. Additional analysis reveals regional variations in adaptation patterns, with western oblasts showing greater integration into European informal networks and eastern regions exhibiting more localized survival strategies [6]^[7]. Temporal analysis indicates that the most rapid transformations occurred during the first six months of conflict, followed by a period of stabilization and incremental adaptation.

Discussion #

The observed transformations in Ukraine’s shadow economy have significant implications for both conflict economics and informal economy theory. First, our results challenge the conventional view that informal economies uniformly contract during crises, instead demonstrating their capacity for structural innovation and reinvention [7]^[8]. This adaptive capacity aligns with the resilience perspective but must be balanced against the vulnerability perspective, as our data simultaneously reveals increased exploitation risks for marginalized participants [8]^[9]. Second, the speed and scale of digital adoption observed suggest that conflict can act as a catalyst for technological leapfrogging in informal sectors, particularly where formal digital infrastructure remains functional [9]^[10]. This has important implications for humanitarian interventions, which could leverage existing digital informal networks for aid delivery while implementing safeguards against misuse. Third, the emergence of hybrid governance structures—combining community self-regulation with elements of armed group oversight—points to novel forms of social order that emerge in institutional vacuums [10]^[11]. Understanding these hybrid systems is crucial for designing effective post-conflict reintegration strategies that neither ignore existing informal governance nor inadvertently legitimize exploitative arrangements. Finally, our findings underscore the importance of considering informal economies not as residual sectors but as active agents of conflict adaptation, whose transformations can significantly influence conflict duration and recovery trajectories. Policy implications include the need for conflict-sensitive humanitarian programming that engages with informal economic actors, the development of monitoring systems capable of tracking informal market adaptations, and the inclusion of informal economy representatives in peacebuilding consultations.

Conclusion #

Armed conflict fundamentally reshapes informal market structures through interconnected mechanisms of institutional vacuum creation, necessity-driven diversification, digital acceleration, network reconfiguration, and risk landscape alteration. In the Ukrainian context, these processes have produced a shadow economy that is both more diverse and digitally integrated, yet simultaneously more polarized in terms of risk and opportunity. Our study contributes to conflict economics by demonstrating that informal economies are not passive victims of disruption but active adapters whose structural transformations warrant explicit consideration in conflict analysis and policy formulation. For practitioners, the findings suggest that effective engagement with informal economies in conflict zones requires moving beyond simplistic formalization strategies to nuanced approaches that recognize and support adaptive capacities while mitigating exploitation risks. Future research should extend this modeling framework to other conflict contexts to assess the generalizability of observed mechanisms and explore longitudinal patterns of informal market evolution throughout conflict cycles. As warfare increasingly converges with economic competition, understanding the adaptive dynamics of informal markets will be essential for building resilient and equitable post-conflict societies. This research underscores the need for interdisciplinary approaches that combine economic analysis with conflict studies to fully capture the multidimensional nature of wartime transformation.
