SINGAPORE- The yen sank to a three-month low on Monday as investors figured the loss of a parliamentary majority for Japan’s ruling coalition in weekend elections would slow interest rate rises, while the US dollar headed for a monthly gain on rising Treasury yields.
In the Asia session, the yen weakened as far as 153.88 per dollar and 166.06 per euro – on both counts its softest since late July. The yen was last down about 0.7 percent on the dollar with a 6.4 percent drop through October – the largest of any G10 currency.
A period of wrangling to secure a coalition is now likely after the Liberal Democratic Party and its junior partner Komeito won 215 lower house seats to fall short of the 233 majority.
Traders said the election would likely result in a government without the political capital to preside over rising rates and could usher in another era of revolving-door leadership.
Fumio Kishida may have been just short of three years in office but successor Shigeru Ishiba is still only Japan’s fourth prime minister in a little over four years and further instability was widely expected to breed caution at the central bank, which meets to set rates this week.
“It’s one more thing for them to consider when they should be looking at the economy,” said State Street’s Tokyo branch manager Bart Wakabayashi. “Are we going to have another series of prime ministers every 10-12 months? That would not be good for the yen.”
Analysts at BNY said the next immediate target for dollar/yen would be 155 with 160 a likely line in the sand that would draw intervention from the finance ministry.
Elsewhere, the dollar was pushing higher and on course for its largest monthly rise in two and a half years as signs of strength in the US economy. Bets on Donald Trump winning the presidency lifted US yields in anticipation of policies that could delay interest rate cuts.
