macroeconomic instability often fuels spikes in violence: a recession in LAC is associated with a 6 percent increase in homicides the following year, while inflation spikes above 10 percent are linked to a 10 percent rise in homicides the year after. Growing inequality further exacerbates the link between economic stagnation and crime.
sound economic policy plays a preventive role. Stability, low inflation, robust social safety nets, and opportunities that reduce inequality and expand access to education and employment are critical to breaking the cycle of violence and stagnation. Financial authorities are also uniquely positioned to weaken criminal networks by addressing illicit markets, curtailing financial flows, and tackling money laundering—cutting off resources that sustain organized crime.
because the impact of crime extends far beyond direct economic costs, economic policymakers must adopt a broader role by targeting high-risk groups, improving crime monitoring, and enhancing interagency coordination.
In Rosario province, Argentina implemented a comprehensive strategy to combat crime, including territorial control of high-risk neighborhoods by the Federal Police, stricter prison systems for high-profile offenders, and collective prosecution of criminal groups under new legislation like the anti-mafia law. These efforts, alongside progress on a juvenile penal code to deter drug traffickers from recruiting minors, have led to 65% reduction homicides in 11 months. In Honduras, strategic security reforms contributed to a 14% decline in the homicide rate and an 8% increase in public confidence in law enforcement.
