100 Days of Iran War: Space & Defense on Edge as 40% of Global GDP Stalls

For space and defense firms, the prolonged Iran conflict is more than a geopolitical flashpoint—it’s a direct driver of budgets, contracts, and investor confidence. With the Federal Reserve and Bank of England staying guarded on rate moves, and a G7 peace summit underway, the sector is parsing every signal to gauge whether defense spending will surge or secular stagnation will starve innovation.

The Iran war has reached a grim milestone at 100 days, and the world's most powerful central banks are responding not with action, but with a collective holding pattern. As the conflict grinds on, the Federal Reserve and Bank of England are widely expected to keep interest rates unchanged at their upcoming meetings, reflecting profound uncertainty about whether the war is a greater threat to inflation or to economic growth. This stance, mirrored by peers from Sweden to Switzerland, comes as more than 20 monetary authorities representing upwards of 40% of global output prepare to make rate decisions in a single week—a synchronization that books end the first half of 2026 with a resounding message of caution.

With the Federal Reserve and Bank of England staying guarded on rate moves, and a G7 peace summit underway, the sector is parsing every signal to gauge whether defense spending will surge or secular stagnation will starve innovation.

The backdrop is a war that has already reshaped energy markets, disrupted trade routes, and injected a sustained geopolitical risk premium into global finance. For the space and defense sector, the implications are acute. Defense spending is historically reactive to conflict: prolonged engagement typically spurs budget increases, accelerates procurement, and boosts research into advanced weaponry and surveillance. Yet the central banks' paralysis signals that policymakers are unsure whether the conflict will evolve into a broader economic shock that saps fiscal capacity. A hawkish pivot could choke off the cheap credit that fuels ambitious space projects; a dovish hold might sustain equity markets but delay necessary adjustments.

All eyes are on the Federal Reserve, which convenes on June 16–17 under newly installed Chairman Kevin Warsh, a former governor whose last tenure predated the post-2023 rate cycle. His first decision will set the tone for US monetary policy amid a fluid geopolitical landscape. Simultaneously, President Trump's attendance at the G7 summit in France on June 15 adds a diplomatic wildcard: a peace deal could rapidly deflate the war-driven demand for missiles, drones, and space-based intelligence, while a failure to negotiate might entrench a militarized posture for years. The Bank of England, grappling with its own stagflation risks, exemplifies the dilemma: hike to combat war-induced energy inflation, or hold to cushion a potential recession.

Divergence is already crystallizing within the advanced-economy club. The European Central Bank recently delivered its first rate increase since 2023, signaling that the eurozone sees inflation as the dominant risk—a view that has buoyed defense-focused equities in the region. Meanwhile, the Bank of Japan is expected to continue its exit from ultra-low borrowing costs, a move that could strengthen the yen and squeeze Japanese defense contractors reliant on export markets. The Swiss National Bank, isolated by safe-haven flows into the franc, is likely to keep rates at zero, underscoring the fragmentation of policy responses.
