Il Nuovo Postiglione - Bank of Japan warns of 'high uncertainties' after election

Prime Minister Shigeru Ishiba's coalition lost its majority in Sunday's snap vote, likely forcing him to head a minority government with support from other parties to pass legislation.

Businesses and economists worry that as concessions to other parties, Ishiba, 67, will offer tax cuts and higher spending, and go slow on reforms needed to improve Japan's competitiveness.

There are also concerns that the government may pressure the BoJ to take a break from the gradual normalisation begun this year of its ultra-loose monetary policy, even if it leads to a weaker yen.

Yuichiro Tamaki, head of the opposition Democratic Party for the People (DPP) -- which Ishiba has been courting for support -- on Tuesday urged the BoJ "to avoid making big policy changes now".

For a long time, the BoJ was an outlier among major central banks, sticking to its ultra-loose policy to spur inflation after the "lost decades" of stagnant or falling prices.

The BoJ ditched negative rates in March, lifting borrowing costs for the first time since 2007 and then again in July -- signalling more was to come.

The BoJ on Thursday kept its main short-term policy rate at 0.25 percent, as widely expected, warning of "high uncertainties surrounding Japan's economic activity and prices".

The bank also said it was paying "due attention" to other economies, particularly the United States ahead of presidential elections on November 5.

The BoJ again signalled that it would raise borrowing costs if inflation develops as it expects, saying the Japanese economy "is likely to keep growing at a pace above its potential growth rate".

The central bank said it expected inflation of 2.5 percent for the current fiscal year to March 2025 before moderating to 2.0 percent in the following two years.

- Outlier -

Before becoming leader of the Liberal Democratic Party (LDP) in September, Ishiba openly backed the BoJ continuing to normalise its policy.

But after the yen surged and stocks tumbled once he took office he rowed back, saying he did not believe Japan was "in the environment for further rate hikes".

The head of the LDP's junior coalition partner Komeito, meanwhile, announced his resignation from the post on Thursday after his party lost eight seats in the election, including his own.

The election left Komeito and the LDP, which has governed Japan almost non-stop since 1955, with a combined 215 seats, 18 short of a majority in the 465-lawmaker lower house.

The centrist DPP, which won 28 seats, officially told the LDP on Thursday it would not join a coalition, but agreed to "cooperate on a case-by-case basis".

A special legislative session will convene on November 11 for a vote to name the next prime minister, with Ishiba lacking enough support to maintain his position in the first round.

Whoever wins the most votes in a second round will become premier, even without a majority.

The DPP said it will symbolically back its leader Yuichiro Tamaki, effectively blocking the main opposition leader Yoshihiko Noda from gathering enough support for his own bid.

Former premier Noda is head of the Constitutional Democratic Party (CDP), which reinforced its position as the second-biggest with 148 seats, up from 96 at the last election.

"As far as the vote for the premiership, we communicated (to the LDP) that for the first and second rounds, we will vote Yuichiro Tamaki," DPP secretary general Kazuya Shimba said after meeting with LDP executives.

Stefan Angrick, an economist at Moody's Analytics, said that "abrupt policy shifts" were possible and that the longevity of Ishiba's government was in doubt.

"With the yen weakening, we expect another rate hike before the end of the year," Angrick said.

"Although some members of the LDP and opposition currently oppose rate hikes, we expect those voices to fade if the yen tumbles further."
