Japan Bond Yields Hit 2.8% and Yen Sinks to 163 as Takaichi Pushes ¥370 Trillion Plan
2 articles · Updated · The Guardian · Jul 27
Summary
Japanese government bond yields have climbed to 2.8%—their highest in 29 years—while the yen has slid to 163 per dollar, a four-decade low, as investors recoil from Sanae Takaichi’s ¥370 trillion industrial spending blueprint.
The market backlash centers on financing: Takaichi’s government has outlined investment across 17 sectors through 2040 but has not shown where the money will come from, prompting warnings of a UK-style unfunded-budget shock.
Japan enters the plan with debt still above 230% of GDP after peaking near 260% in 2020, and a weaker yen is already lifting import costs and threatening to push core inflation into the mid-2% range later this year.
The blueprint aims to lift growth above 1% through bets on AI, semiconductors, biotech, defense, energy and shipbuilding, but economists’ forecasts for 2027 and 2028 remain below that target.
Can Japan successfully absorb massive AI and semiconductor investments while facing a severely shrinking and ageing workforce?
Will Takaichi’s ¥370tn gamble trigger a catastrophic debt crisis, or finally shatter Japan's decades-long economic stagnation?
Is this historic industrial spending plan a genuine economic strategy, or a disguised geopolitical weapon against Chinese dominance?
From Yen Meltdown to Fiscal Reckoning: Tracking Japan’s High-Stakes ¥370 Trillion Growth Strategy
Overview
In July 2026, Japan faced a historic market shock as the yen collapsed past 163 against the dollar, driven by a widening interest rate gap between the U.S. and Japan. The Federal Reserve kept rates high while the Bank of Japan tightened only gradually, fueling capital outflows and speculative trades. At the same time, Middle East conflicts pushed oil prices higher, worsening Japan’s trade deficit and causing persistent inflation. Rising import costs eroded real wages and household purchasing power. As government debt-servicing costs soared, concerns grew that essential social programs could be crowded out, especially as Prime Minister Takaichi’s expansionary policies triggered market anxiety and forced a more cautious approach to tax cuts.
