Capitalizing on his sweeping electoral victory over the weekend, Japan’s next prime minister, Shinzo Abe, stepped up pressure Monday on the Bank of Japan to ease monetary policy dramatically in an effort to end deflation and jump-start the country’s economy.

Abe’s center-right Liberal Democratic Party scored an overwhelming victory in Sunday’s parliamentary election after a highly unusual campaign in which he focused his attacks more on the central bank than on the outgoing government of Prime Minister Yoshihiko Noda. NHK public TV said Monday the LDP had won 294 seats in the 480-member lower house of parliament while its ally, the New Komeito party, won 31 seats, giving them the two-thirds majority needed to overrule most matters in the upper house, where Noda’s Democratic Party of Japan holds the largest number of seats.

During the campaign, Abe had declared that the top priority of an LDP government would be to bring an end to the deflation that has plagued Japan’s economy for 15 years. To that end, he called on the Bank of Japan to double its inflation target, to 2 percent, and to ease aggressively along the lines of the U.S. Federal Reserve Board to reach that goal. He also identified the strong yen as an archenemy of business and vowed to press for measures, including purchases of foreign bonds by the BoJ, to weaken it. Abe even threatened to override the central bank’s independence if it didn’t bow to the will of the government.

Abe kept up the pressure at a post-election news conference on Monday. “It was very rare for monetary policy to be the focus of attention in an election, but there was strong public support to our view,” he said. “I hope the Bank of Japan takes this into account” when its policymaking body meets this Wednesday, he added.

Financial markets reacted to the LDP victory by pushing the yen lower, to 83.78 to the dollar from 83.45 on Friday, and driving up Japanese stock prices. The Tokyo Stock Exchange’s Nikkei 225 index rose 91.32 points, or just under 1 percent, to 9,828.88.

Japan’s central bank has long drawn criticism from outside economists for its seeming passivity. The bank’s determined effort to rein in asset prices in the late 1980s effectively burst the country’s property bubble and set in train a lengthy period of stagnation — the so-called lost decades — that have produced a stubborn deflation. The BoJ was slow to adjust to the changed circumstances. It didn’t adopt an inflation target until February 2012 and then set it at a mere 1 percent, the lowest of any major central bank. Although the BoJ has bought bonds over the past decade, it has resisted the bold intervention style and explicit economic targets adopted by the Fed.
