japan-mortgage-fixed-vs-floating-at-crossroads-as-boj-rate-hits-1-percent
- After the BOJ's June hike took the policy rate to 1.0%, floating mortgage rates are set to rise in October
- Toyo Keizai staged an expert debate: fixed or floating in a rate-hike cycle
- Floating loans' edge assumed slow hikes; consecutive hikes are eroding that premise
- Fixed loans buy rate certainty at the cost of higher monthly payments now
- Overseas owners of Japanese property should re-run cash flows before October
With the Bank of Japan's policy rate at 1.0% after the June hike, Japan's floating mortgage rates are expected to rise again in October, when banks customarily reset them. Toyo Keizai staged a full debate between experts on the classic question, now with real stakes: fixed or floating? For two decades floating rates around 0.3-0.5% made 'bet on no hikes' a national consensus, with over 70% of new loans floating. That premise is being dismantled by consecutive hikes. The choice is a risk trade: floating means you carry rate risk for a lower payment; fixed means paying a premium to transfer it. Key variables are remaining tenor, cash-flow headroom, and your view of the BOJ's terminal rate. For overseas investors holding yen mortgages on Japanese property, re-run debt-service coverage before the October reset; for new borrowers, stress-test at post-hike rates plus a buffer. Watch October's actual resets, BOJ signals on the terminal rate, and whether the fixed-rate share of new loans finally climbs — the true sign that Japan's rate expectations have turned.
