North Korea's missile testing tempo has accelerated in 2026, with multiple short-range ballistic launches in September—including two hypersonic glide vehicle-equipped systems on September 20 from the Wonsan area and another pair in early October—driven by weapons modernization efforts, responses to U.S. sanctions, and reactions to trilateral military exercises. Traders assign the highest probability to one or two tests in October because the regime typically calibrates activity to signal resolve without triggering major escalation, while Kim Jong Un's factory visits and production directives support sustained but not daily launches. Key variables include upcoming diplomatic windows, sanctions developments, and any U.S.-South Korea drills that could prompt responsive firings, leaving room for zero or three-plus outcomes if the pattern shifts abruptly.
