Japan’s 17 Trillion-Yen Stimulus Plan Sparks Debt ConcernsPrime Minister Sanae Takaichi is expected to finalize a 17 trillion-yen (about $109 billion) spending package this week, equal to roughly 2% of Japan’s economy, said Commonwealth Bank of Australia strategist Carol Kong, as reported by WSJ. Kong warned that the plan is raising concerns over “The stimulus plans will weaken Japan’s ability to sustain its already outsized public debt,” as quoted by WSJ.

Why Markets Fear Japan’s Fiscal Path Is WorseningExpectations for large-scale spending have grown since Takaichi, widely viewed as a fiscal expansionist, won the ruling party’s leadership election last month, as per the report. Takaichi’s victory boosted hopes for stronger government support, particularly after new data showed that Japan’s economy contracted in the July–September period for the first time since early 2024, reported WSJ.

BOJ Caught Between Inflation and Political PressureThe timing is challenging for the Bank of Japan (BOJ). The central bank has kept interest rates unchanged at 0.5% since January due to uncertainties surrounding US tariffs, even as inflation continues to hover above its 2% target, reported WSJ.
Prime Minister Takaichi has repeatedly emphasized the need for close coordination between the government and the BOJ, comments that some analysts interpret as resistance to raising rates in the near term, as per the report.
Razaqzada noted, “The new government seems to be trying to have it both ways: implementing a massive fiscal stimulus package worth 17 trillion yen while opposing monetary policy normalization by the Bank of Japan,” as quoted by WSJ.
