The Bank of Japan is accelerating the pace of its monetary policy tightening.

According to a report from the Nikkei newspaper on Tuesday, the central bank plans to raise its benchmark interest rate from 0.75% to 1.0% at its policy meeting scheduled for the 15th and 16th of this month. It also intends to halt the reduction of its government bond purchases after April 2027. A former central bank official, cited by Bloomberg, suggested that a subsequent rate hike could follow as soon as October.

The Nikkei report indicates that Governor Kazuo Ueda will present the rate hike proposal at the meeting on the 16th, which is expected to gain majority support from the nine-member policy board. Concurrently, a proposal to cease the reduction of bond purchases has also secured majority backing from the committee.

These measures represent the first adjustment to the policy rate since last December and serve as the latest signal of the central bank's response to persistent inflationary pressures. The anticipation of a rate hike has already exerted a noticeable impact on Japanese financial markets, with significant volatility recently observed in the government bond market.

Rate Hike Trajectory: June Implementation, October Potentially Next

According to Bloomberg, former Bank of Japan executive director Hideo Hayakawa stated in an interview on Tuesday that following a June hike, "the next rate increase could come as soon as October." He remarked directly that "the BOJ is a little behind the curve, so it needs to catch up at some point."

Hayakawa's assessment is based on widespread market concerns that the central bank has been slow to respond to inflation. There is a growing market perception that, in the face of persistently strong inflationary pressures, the Bank's previous actions have been insufficient, making the June hike a kind of "catch-up" adjustment.

Hayakawa also noted that recent severe volatility in the Japanese bond market, coupled with market apprehensions regarding the fiscal policy direction under Prime Minister Sanae Takaichi, is complicating the decision-making environment for the central bank. The combination of these factors with inflation pressures leaves the Bank with little choice but to respond proactively.

Halting Bond Purchase Reductions: Putting the Brakes on Quantitative Tightening

Alongside adjustments to interest rate tools, a significant change is also expected in government bond purchase policy. The Nikkei reports that the Bank of Japan plans to stop its quarterly reductions of bond purchase amounts after April 2027, a direction already supported by a majority of policy board members.

This move implies that while continuing to raise interest rates, the central bank will temporarily slow the further contraction of its balance sheet, thereby maintaining a degree of flexibility in its monetary policy pacing.
