Yen's Biggest Decline in Decade No Anomaly With Options Fading

Options traders are growing less bullish on the yen after efforts by Japanese officials to boost the world’s second-biggest economy and a U.S. jobs report led to the currency’s biggest weekly decline in a decade.

Japan’s currency plunged 2.5 percent against the dollar and 1.3 percent versus the euro on Dec. 4 after America’s Labor Department said employers cut the fewest jobs since the recession began. The yen sank 4.5 percent versus the greenback for the week, the most since February 1999 and retreating from a 14-year high. Traders sold yen and bought dollars on speculation interest rates in the U.S. will increase before June.

“The improving U.S. jobs market suggests the Federal Reserve won’t stand pat on interest rates longer than the Bank of Japan,” said Kazutoshi Yasuda, general manager of the markets department in Tokyo at FX Prime Corp., a unit of Itochu Corp. Increased U.S. borrowing costs would lead traders to favor using yen to finance higher-yielding investments, leading to more losses for the Japanese currency, he said.

Options showed declining bets that the yen will rise. The odds for a gain to 84.5 yen per dollar by the end of March from 90.56 last week fell to 38 percent from 80 percent on Nov. 30, data compiled by Bloomberg show. Chances of a decline to 92 versus the dollar by Dec. 31 reached 63 percent. Options grant buyers the right to purchase or sell an asset at a predetermined price.

Weekly Tumble

The yen tumbled 3.6 percent versus the euro to 134.54 last week, the sharpest slide since the week ended April 3. The yen’s biggest drop during the week came after the U.S. Labor Department said payrolls dropped by 11,000 last month, the smallest decrease since the recession began in December 2007.

“What the job numbers do is firm up expectations that the Fed interest-rate hike is coming,” said Camilla Sutton, a strategist in Toronto at Bank of Nova Scotia, the nation’s third-largest lender. “That should be a strong-dollar story.”

Federal-funds futures contracts on the Chicago Board of Trade show a 43.3 percent probability that the U.S. central bank will lift its target rate for overnight bank borrowing to 0.5 percent by June from a range of zero to 0.25 percent now, up from 12.6 percent a month ago.

UBS AG expects the Fed to set its key rate at the top end of its 0.25 percent range in April and follow with a quarter- point increase in June. The jobs report and last week’s gains “suggest the greenback is finally turning,” Mansoor Mohi-uddin, the Zurich-based bank’s global head of currency strategy, wrote in a note to clients.
