Bank of Japan could announce major policy shift this week
Japan's central bank is due to meet this week amid soaring government bond yields and a strong yen, with a number of economists expecting it to scrap its yield curve control policy.
The move would come less than a month after the Bank of Japan caught markets off guard by widening its tolerance range for 10-year Japanese government bond yields. Since then, 10year JGB yields have exceeded the upper ceiling of the new range - 50 basis points either side of its 0 percent target - a number of times.
Indeed, Nikkei reported that the Bank of Japan purchased JGBs worth more than 2 trillion yen ($15.6 billion) after the nation's 10-year bond yield curve topped 0.5 percent for two consecutive sessions.
The dollar is down almost 14 percent against the yen over the last three months, and the 10-year bond yield has jumped from 0.256 percent on Dec. 19 to around 0.502 percent on Jan 16.
Bank of America Global Research's economists expect the BOJ to keep its benchmark rate unchanged at an ultra-dovish 0.1 percent on Wednesday, but said it could scrap the yield curve control policy altogether.
"Our base case is for a hold, but with low conviction, and see a significant risk that the central bank announces the end of Yield Curve Control (YCC) as the dysfunctions in the bond markets that prompted December's YCC modifications have gotten significantly worse," Chief Japan Economist Izumi Devalier and her team said in a recent report.
"Our client conversations suggest domestic investors now see YCC removal as a base case," the economists wrote, adding that FX markets had already priced in such a move. They noted that it would likely be viewed by the market as similar to a rate hike.
While the central bank leaving interest rates unchanged would be positive for Japanese stocks, BofA said a removal of its yield curve control policy could lead to sharp declines. "In our main risk scenario where the BoJ scraps YCC, we think that TOPIX could decline up to 3% in the near term, with key rate-sensitive sectors, such as banks, potentially outperforming," economists wrote.
Morgan Stanley's Japan Chief Economist Takeshi Yamaguchi also acknowledged the possibility of such a scenario. "We acknowledge lingering risk of the BoJ suddenly modifying or abolishing the YCC approach at each future meeting, including the January meeting," Yamaguchi said, adding "the nature of the YCC makes it difficult for central banks
lay the ahead of time, in contrast to revision of the negative interest rate."
HSBC, meanwhile, expects the central bank to announce further widening of the yield curve control tolerance band instead of abolishing the policy altogether.
Paul Mackel, HSBC's global head of FX research, said the firm expects the central bank to widen the range to 75 basis points either side of its 0% target for the 10-year government bonds in the first quarter of 2023, before Governor Haruhiko Kuroda steps down in early April.
"As a result of the December revision, market participants need to take into account the risk of Mr. Kuroda suddenly changing his explanations," he said, pointing to the governor's somewhat confusing descriptions of widening the YCC band.
In September, Kuroda said that widening the tolerance range constituted "a rate hike or monetary tightening." However, at the BOJ's December briefing, Kuroda insisted the policy revision "was not a rate hike." "We think it is reasonable to assume that the Bank is currently at a stage of assessing the effect of this policy revision," Yamaguchi said.
"I don't think the BOJ will scrap their inflation target altogether, but they might announce a target range of 2-3 percent," Simpson told CNBC. "We know that the PM [Prime Minister Fumio Kishida] has been calling for more flexibility with the inflation target, and this seems like a plausible compromise from the BOJ," he said.
Japan's core inflation is expected to hit 4.0 percent for December, according to a Reuters poll - a 41-year-high, although still well below levels seen in comparable Western economies.
