LONDON, Sept 16 (Reuters) - The dollar was on course to fall for a second week against the yen on Friday after U.S. retail sales data quelled lingering bets on the Federal Reserve raising interest rates next week, while faith in Bank of Japan action against its currency also seems limited.
The past week has been dominated by a rethink on debt markets about the outlook for central bank policy in Europe and Japan. One currency leg of that looks to be the growing lack of belief that officials can do much to weaken either the euro or yen if the U.S. Federal Reserve does not raise interest rates.
The yen gained 0.2 percent against the dollar in early trade in Europe, down 0.7 percent for the week, while the euro was roughly steady at $1.1237. The index which measures the dollar's broader strength, however, was broadly steady at 95.320. .DXY
"The Fed is looming in about 5 days. Until then we doubt that the dollar is going to swing either way," said Alexandre Dolci, a strategist at Spanish bank BBVA (MC:BBVA) in London.
"If anything we may see more about the yen and this is what the option market is pricing-in. Given that the BoJ has had a good track record for disappointing the market since the start of the year, the risk is the yen could strengthen a little bit against the other majors."
He said his bank had a target of 108 yen per dollar for the end of the year, predicated on the Fed raising interest rates in December, although that seemed subject to risks from November's presidential elections.
"Explicitly they can't say anything (about Trump)," he said. "But we think they would want to see further the reaction of the market to figure out what to do on interest rates (if he wins)."
The Fed and the Bank of Japan both issue their decisions on interest rates and other policy parameters next Wednesday.
Financial markets are pricing in a roughly 12 percent probability of a Fed rate hike next week, down from 15 percent before the data, according to the CME FedWatch tool.
The BOJ is due to conduct a comprehensive review of its current policy framework that combines negative interest rates with a massive asset-buying programme. market players expect it to indicate a preference for a steeper yield curve to cushion the blow on banks from negative interest rates, but there is also focus on whether the central bank will cut rates deeper into negative territory.
"I think the market has somewhat priced in a (rate) cut as well as a tweak to the QE programme," said Sim Moh Siong, FX strategist for Bank of Singapore.
"If the BOJ stays put then I would expect the yen to come under some appreciation pressure, especially if the Fed stays put as well."
