* Dollar down 0.4 pct at 85.42 yen
* Dip below 15-yr low 84.82 could pave way towards 80 yen
* Weaker U.S. outlook, talk of Fed easing undermines dollar
* Japan's Noda: recent forex moves one-sided
* U.S. ADP jobs report eyed for direction

The dollar neared a 15-year low against the yen on Wednesday, staying under pressure across the board as weak U.S. data and talk of further policy easing by the Federal Reserve weighed on Treasury yields.
Data on Tuesday showed U.S. home purchase contracts tumbled to a record low in June while factory orders fell more steeply than expected, implying an anaemic economic recovery for the remainder of this year.    The numbers added to talk that the Fed might start a new round of Treasuries buying to pump funds into the economy.
As the yen rose near highs last seen in 1995, Japanese Finance Minister Yoshihiko Noda appeared to ramp up the administration's verbal warnings, saying current moves in the yen were somewhat one-sided.
"Excessive and disorderly currency moves would negatively affect stability in the economy and financial markets, and therefore it's undesirable. In this regard I am closely watching market moves further," he added.    But analysts said it would be difficult for Japanese authorities to step in to weaken the yen at this stage.
Weak U.S. data and speculation of Fed easing pushed down U.S. two-year Treasury yields to a record low of 0.52 percent on Tuesday, suggesting limited upside for the dollar.  
"We see further dollar weakness ahead, with the Fed making it clear its priority is to support growth," said Ulrich Leuchtmann, currency analyst at Commerzbank.
The dollar fell as far as 85.32 yen, its lowest since late November, and was trading at 85.42 at 1100 GMT, down 0.4 percent on the day. Traders said a decline beyond the 15-year low of 84.82 yen hit in November could open the way for the dollar to slide to the all-time low below 80 yen.
Hefty options barriers are thought to be set around 85 yen, meaning a drop in the dollar could pick up speed below that level.

Perekonomian AS tampak kembali mengalami perlambatan, di mana beberapa hasil data ekonomi AS kemarin malam kurang memuaskan.

Saat ini Pair USD/JPY berada dikisaran 85,35 setelah pada akhir perdagangan pasar New York dini hari tadi ditutup di posisi 85,86. Suatu penurunan di bawah 85.00 "tampak tidak dapat dihindari," ujar senior dealer di quasi-public financial firm di Asia.

"Saya tidak mengekspektasi dollar jatuh di bawah Y85.00, tetapi pasar mulai berkomentar tentang stop-loss level penjualan besar selanjutnya di Y84.50," ujarnya. Trend USD lemah saat ini sepertinya terus sampai meeting FOMC pekan depan, menempatkan support di 82.00 untuk sekarang.

Data-data ekonomi yang dirilis kurang bersahabat kemarin memperkuat spekulasi the Fed akan terpaksa kembali terjun ke pasar untuk membeli sekuritas, atau program yang bernama Quantitative Easing (QE).

Sebelum data tersebut, datang pemberitaan dari Wall Street Journal bahwa the Fed sedang mempertimbangkan untuk membeli kembali sekuritas mortgage dan obligasi pemerintah.
