This study examines four key factors—supply chain diversification, reshoring initiatives, logistics disruptions, and cost shocks—to explore the transition from the era of "Fragile Efficiency" to a system focused on overall viability. Drawing on global trade data from 2024–2026 and analytical frameworks provided by the IMF, the research introduces the concept of the Resilience–Efficiency Frontier (REF). The findings show that moving from Just-in-Time (JIT) to Just-in-Case (JIC) manufacturing helps reduce the volatility caused by the Bullwhip Effect but also creates a persistent form of "Complexity Inflation." Empirical results indicate that firms are now incurring a "Resilience Premium" of 12–15% to protect their production and distribution networks. The study also emphasizes that trade is no longer purely economic but is increasingly connected to national security and environmental regulations, such as the EU’s Carbon Border Adjustment Mechanism (CBAM). This marks a clear shift from the deflationary trends that characterized global trade in the past. 2025 27 34 4239 https://creativecommons.org/licenses/by/4.0/ 10.54216/JIER.020205 https://americaspg.com/journal/42/article/4239 https://americaspg.com/storage/51768060558.pdf
