(Bloomberg) -- The yen is coming under renewed pressure as a powerful earthquake that hit Japan on New Year’s Day makes it harder for the Bank of Japan to abolish negative interest rates this month. 

Morgan Stanley MUFG Securities Co. changed its call for the BOJ rate decision this month and now sees it leaving current policy in place, partly as the central bank has to assess the adverse impact from the Noto Peninsula disaster on the economy. While speculation about a January tweak is receding, many still expect an end to negative rates in April, or later in 2024. 

The yen weakened to as low as 144.30 per dollar on Thursday, from 141.04 at the end of 2023 in New York trading. The Japanese currency had been widely expected to strengthen in 2024 on speculation the Federal Reserve would start cutting interest rates in the first half of the year, while at the same time normalization of ultra-easy monetary policy in Japan would narrow the yield gap between the two economies. 

“Although there must be quite a few foreign investors who have been anticipating the end of negative rates in January, under these circumstances, the BOJ will almost certainly not move this month,” said Daisuke Karakama, chief market economist at Mizuho Bank Ltd. “Should negative rates not be lifted in January, ending it in the first half of 2024 will also become doubtful.”

Mari Iwashita, chief market economist at Daiwa Securities Co., removed her forecast for an end to negative rates in January following Governor Kazuo Ueda’s speech on Dec. 25 and his interview with NHK on Dec. 27. 

“The January move seems even more impossible,” Iwashita said. The earthquake is likely to depress production activity while the government may have to set up a supplementary budget for recovery measures, she said. Iwashita now expects an exit from negative rates in April. 

Ueda said Thursday in a speech that the BOJ will be fully prepared to support the financial system after the earthquake, and he hopes wages and inflation will rise in a balanced manner this year.

Kentaro Okuda, chief executive officer at Japan’s biggest brokerage Nomura Holdings Inc. is also among those who thinks the earthquake may delay an exit from negative rates from this month, although it depends on the impact of the disaster.

Shares of Kokusai Electric Corp., Murata Manufacturing Co., Hokuriku Electric Power Co., and other companies with factories and operations in the area hit by the tremor slumped as investors tried to assess the damage. But the weaker yen supported automakers such as Toyota Motor Corp.

The yen extended declines for a third day against the dollar and reached a two-week low on shifting BOJ bets. The currency has lost more than 2% this year after dropping 7% in 2023, that biggest loss among Group of 10 peers. 

The yen’s decline following the major tremor is contrary to what happened in March 2011, when a deadly earthquake and tsunami triggered coordinated intervention to sell the yen by Japan, the US and Europe. That move aimed to halt a sharp rally in the yen on the back of repatriation of assets held overseas by Japanese companies. 

Japan’s currency subsequently hit an all-time high of 75.35 in October that year. 

Mizuho’s Karakama said that Japan had accumulated trade surpluses over many years at that time and corporate demand for the yen supported the currency’s appreciation. It now has a deficit.  “It’s unreasonable to expect the same reaction in the yen to the earthquake,” he said.

“Any lingering expectation for an end to negative rates in January is completely shattered,” said Ataru Okumura, senior Japan rates strategist at SMBC Nikko Securities Inc.
