The yield on Japan's 10-year government bond surged to a 30-year high of 2.93% on Monday, driven by increasing market expectations that the Bank of Japan (BOJ) will accelerate its monetary tightening and deliver an earlier-than-expected interest rate hike. This move comes despite weaker-than-expected GDP data, which showed the Japanese economy expanded at an annualized 1.1% in the second quarter, falling short of the 2% market forecast.
Traders are speculating that the BOJ could raise rates as soon as September, influenced by a growing number of policymakers advocating for a stronger response to persistent inflationary pressures. The central bank's efforts are also complicated by a persistently weak yen, which could further exacerbate inflation.
Earlier this month, the BOJ marginally raised its GDP growth forecast for the fiscal year ending March 2027 to 0.6% from 0.5%. The government, under Prime Minister Sanae Takaichi, is also pursuing a substantial long-term investment plan exceeding JPY 370 trillion.
