Japan's Rising Interest Rates: A Burden on Younger Households

Japan's Cabinet Office has released estimates on the impact of rising interest rates on household finances. Under a scenario where borrowing rates increase by 1% and deposit rates by 0.6%, households in their 30s with mortgages would face an average annual burden increase of approximately ¥240,000 (about $1,521). This is based on actual rate increases from 2023 to 2026 following the Bank of Japan's policy shifts.

The estimates also show that households in their 70s, who typically have no mortgage and hold substantial financial assets, stand to gain roughly ¥80,000 (about $507) per year. This highlights the widening disparity in impacts both across and within generations.

Younger and middle-aged cohorts in their 20s to 40s see a net negative impact on average, as a high proportion of these households hold mortgage contracts. The increase in loan payments triggered by rising rates outweighs the additional interest income from higher deposit rates.
