The Bank of Japan raised its policy interest rate from 0.75% to approximately 1% on Tuesday [1].

This decision signals a significant shift in monetary policy to curb rising prices, though it threatens to increase the financial burden on homeowners with floating-rate mortgages.

The move was decided during a monetary policy meeting held from June 15 to June 16 [1, 2]. Eight members of the policy board participated in the vote, with seven in favor and one member, Asada, opposing the hike [1]. This is the first time the policy rate has reached the 1% level since 1995 [1].

Bank of Japan Deputy Governor Shinichi Uchida said the decision was driven by rising crude oil prices. He said that price pass-throughs in business-to-business transactions are progressing at a relatively fast pace, which could lead to price increases across a wide range of consumer items.

"We have judged that there is a risk that the underlying rate of price increase will exceed the 2% price stability target," Uchida said [1].

The rate hike comes amid a period of record-breaking market activity. The Nikkei 225 stock average recently reached a historic high of approximately 70,000 yen, marking the first time the index has entered the 70,000-yen range [1].

However, the increase in rates is expected to impact households. Some estimates suggest that the total payment for certain home loans could increase by more than 10 million yen [5].

The policy rate has reached the 1% level for the first time since 1995.

The Bank of Japan is moving away from decades of ultra-loose monetary policy to prevent the economy from overheating due to cost-push inflation. By raising rates to a level not seen in 31 years, the bank is attempting to stabilize the currency and prices, but it risks dampening consumer spending as mortgage repayments rise for millions of Japanese households.
