As the Japanese election outcome sends shock waves, political uncertainty may delay economic reforms, increase government spending and potentially postpone the Bank of Japan's (BOJ) exit from its outlier monetary policy, economists warned Wednesday.
Post-war Japan has long been a byword for political stability, with the conservative, market-friendly Liberal Democratic Party (LDP) in power for all but four of the last 69 years.
However, the LDP-Komeito coalition lost its majority on Sunday, likely forcing Prime Minister Shigeru Ishiba into a minority government that would need 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.
Since 2021, "the country has had three prime ministers, and Ishiba probably won't last very long in office, either," predicted Marcel Thieliant at Capital Economics.
"That means that sweeping reform projects are unlikely," he said – changes that were already "few and far between" in the past decade.
Syetarn Hansakul from the Economist Intelligence Unit also anticipated a "dilution of (the LDP's) reform agenda," which included plans to increase spending on defense and social welfare.
In addition to investor sentiment, this will "dent confidence among households and businesses. Domestic demand recovery could suffer as a result," she said.
Ishiba has promised more support for households to accelerate wage increases and help revitalize rural areas, but some opposition parties want more.
The Democratic Party for the People (DPP), a potential kingmaker, wants energy subsidies for consumers and lower taxes for part-time workers.
However, while aimed at reducing worker shortages in aging Japan, this would also reduce the government's tax revenues.
Japan already has one of the world's highest debt-to-output ratios at around 250% of gross domestic product (GDP).
Media reports suggest that Ishiba will issue a new economic policy package next month and plans to include some proposals from the DPP.
"(Although) Ishiba appears to appreciate fiscal discipline, he will likely continue to compromise and refrain from discussing additional revenue measures even though they are important in the long run," said Shigeto Nagai at Oxford Economics.
The Japan Business Federation, or Keidanren, urged parties to overcome differences and concentrate on growing the economy.
"Japan cannot afford the luxury of delay in addressing these issues," Takeshi Niinami, the head of the Japan Association of Corporate Executives, said.
All parties should "face the reality of the situation, engage in thorough discussions, and move forward with the necessary policies," he said.
Another uncertainty is the Bank of Japan, which only this year has cautiously begun moving away from an ultra-loose monetary stance and toward greater alignment with other central banks.
Before being appointed LDP leader, Ishiba openly backed this continuing, but after the yen surged and stocks tumbled following his appointment, he rowed back.
The BOJ was expected to stand pat on borrowing costs at its regular meeting on Thursday, but most economists expect the next move upward in December.
Many in the opposition, though, want a pause in order to avoid higher interest rates for consumers and businesses, even if this means a weaker yen and, with it, higher import prices.
Higher interest rates will also make servicing Japan's colossal debts more expensive.
"Becoming desperate to win the Upper House election next year, the Ishiba administration could become more cautious about the pace of rate hikes," Nagai said.
But Masamichi Adachi at UBS said he still expects a hike in December.
"It is true that if financial markets remain volatile, the BOJ is unlikely to raise the rate, but we think political instability will settle once a new government is formed, at least for the time being," Adachi said.
