ING Bank analyzed policy rate levels at the Bank of Japan (BOJ) and Bank of Korea (BOK) on local time 10th, concluding both central banks face approximately 100 basis points of rate hike pressure. The Dutch bank's rate pressure model found current benchmark rates in both countries remain below appropriate levels given economic conditions. ING stated both Japan and Korea should have official rates about 100bp higher than current levels to adequately reflect their respective economic environments.
Japan's Rate Buffer Shows -18bp Gap
ING's rate pressure model calculated Japan's benchmark rate buffer at negative 18 basis points. The model sets a 15-year average as the neutral level, then calculates current rate headroom by combining interest rate differentials with the US, domestic real policy rates, and real policy rate gaps versus the US. A negative buffer indicates the current policy rate remains accommodative relative to economic conditions. ING stated the Bank of Japan needs to secure a positive rate buffer, even marginally, through at least a 25bp additional rate hike.

Inflation and Yen Weakness Drive BOJ Tightening Pressure
Inflation represents Japan's biggest variable. Current consumer price inflation stands at 1.5% year-over-year in stable territory, but ING forecasts inflation could rise again to 2.5-3% levels as government subsidy effects fade and wage increases push up services prices. The current BOJ policy rate of 1% remains low considering future inflation trajectories. Yen weakness also increases tightening pressure on the Bank of Japan. ING's purchasing power parity (PPP) model analysis shows the current dollar-yen exchange rate level produces an easing effect equivalent to approximately 190bp on Japanese monetary policy. The gap between the BOJ benchmark rate and 2-year TONA rate stands at 47bp, partially reflecting additional hike possibilities, while the 2-year to 10-year rate difference of 122bp reflects greater anxiety about long-term rates. ING stated the BOJ's final policy rate destination appears near the 5-year rate around 2%, noting gradual rate hikes by the BOJ sustain yen weakness.
Korea Faces Larger Rate Hike Pressure at -1.2% Buffer
Korea's rate hike pressure exceeds Japan's according to ING's analysis. The ING model calculated Korea's rate buffer at -1.2%. The 40bp difference between the benchmark rate (2.5%) and actual applied rate (2.9%) explains part of this gap, but approximately 80bp of additional tightening room exists even excluding this factor. ING assessed the current negative rate buffer as inappropriate considering Korea's economic situation. Korea's inflation rate stands at 3.2% year-over-year and GDP growth at 3.8%, showing relatively solid momentum that increases the need for monetary policy normalization.

Won Depreciation Adds 120bp Policy Easing Effect
Won weakness was identified as an additional tightening factor for the Bank of Korea. ING analyzed the current dollar-won exchange rate as producing a policy easing effect of approximately 120bp based on PPP standards. Won depreciation effectively creates the same effect as lowering the benchmark rate, increasing additional rate hike pressure. Market expectations differ markedly between Japan and Korea, ING explained. The gap between the BOK benchmark rate and 2-year rate stands at 127bp, substantially reflecting future rate hikes, while the 2-year to 10-year rate difference of 26bp shows limited burden on long-term rates. ING interpreted this as the market trusting the Bank of Korea will implement rate hikes when necessary. ING forecasts the BOK could implement cumulative rate hikes of approximately 100bp, raising the benchmark rate from the current 2.5% to 3.5%. Korea's 5-year rate at 3.95% levels partially reflects this additional tightening possibility.
FAQ
What did ING Bank's analysis reveal about BOJ and BOK policy rates on local time 10th?
ING Bank's rate pressure model found both the Bank of Japan and Bank of Korea face approximately 100 basis points of rate hike pressure, with current benchmark rates remaining below appropriate levels given economic conditions in both countries.
Why does Korea face larger rate hike pressure than Japan according to ING?
ING calculated Korea's rate buffer at -1.2%, larger than Japan's -18bp gap, indicating approximately 80bp of additional tightening room exists. Korea's inflation at 3.2% year-over-year and GDP growth at 3.8% show solid economic momentum requiring policy normalization, while won weakness adds 120bp of policy easing effect that increases rate hike pressure.
How does currency weakness affect monetary policy pressure in Japan and Korea?
ING's PPP model analysis shows the current dollar-yen exchange rate produces an easing effect equivalent to approximately 190bp on Japanese monetary policy, while the dollar-won exchange rate creates approximately 120bp of policy easing effect, meaning currency depreciation in both countries effectively lowers benchmark rates and increases pressure for additional rate hikes.
