Yen climbs after BOJ, Italy debt sale lift euro

The BOJ increased its monetary stimulus for a second month running, this time by 11 trillion yen ($138.5 billion). The yen gained after this, with traders saying there had been speculation of a bigger stimulus.

The euro also gained against the dollar after data showed the Spanish economy contracted slightly less than expected in the third quarter and Italy’s borrowing costs at a sale of five- and ten-year debt.

A report showing US single-family home prices rose in August, the latest sign that the housing market is on the mend, also bolstered risk appetite and demand for the euro.

But trading moves were exacerbated by lighter than usual volume with US markets closed as one of the biggest storms ever to hit the United States battered the eastern seaboard.

“Dollar/yen dove through the 79.50 level in the wake of BOJ announcement on quantitative easing that disappointed the markets,” said Boris Schlossberg, managing director of FX strategy at BK Asset Management in New York. “Many traders were hoping that Japanese monetary officials would deliver a bigger boost.”

The dollar hit a one-week low of 79.25 yen, breaking below important chart support at the 200-day moving average. It was last down 0.4 percent on the day at 79.44 yen.

Friday’s four-month peak of 80.36 was expected to act as resistance for the dollar.

The euro also fell to a two-week low against the yen before reversing course to trade 0.1 percent higher at 103.06 yen.

Spain, Italy News lift euro

The euro was last up 0.5 percent at $1.2968, close to the session peak of $1.2974.

The euro was already bid after data showed the Spanish economy contracted for a fifth straight quarter in the three months to September at a slightly slower rate than forecast.

It was also helped by improved demand at an Italian debt auction.

“There’s been a little bit of speculative buying of euro/dollar because the Spanish GDP data was not so bad as feared,” said Paul Bednarczyk, head of research at 4CAST in London.

In Madrid, Cortal Consors economist said any suggestion that the GDP number marked an upturn for Spain was “a mirage”.

Market players cited bids at $1.2850-80 which should help limit any losses, and expected buying ahead of the 200-day moving average.

“We are very much in a range trade at the moment of $1.28-$1.32,” Bednarczyk said.

Some US$2.97 billion in euros has changed hands so far on the last Tuesday of October, compared with US$4.87 billion for the entire session on the last Tuesday of September, according to Reuters Dealing.

Gains for the euro looked likely to be capped by concerns about whether Greece can agree to a deal on more austerity, and uncertainty over when Spain might request financial aid.

Spanish Prime Minister Mariano Rajoy said on Monday he would seek a credit line from the euro zone’s rescue fund “when I think it is in the interests of Spain”.

Still, expectations the European Central Bank will start a bond buying programme after Madrid asks for a bailout limited speculative euro selling.

Strategists said it was too early to tell what impact the destruction caused across the Atlantic by the giant storm Sandy might have on currency markets.

Demand for the dollar tends to rise in times of reduced appetite to take on risk, but if widespread damage prompted speculation the Fed might ease policy further to shore up the economy, the dollar could fall.
