Tokyo - Asian stocks were pegged back on Friday, with Japanese shares hitting a four-week low and the dollar languishing around an eight-month trough as the US budget standoff dragged on, building fears of increasingly serious economic consequences.
Tokyo's Nikkei fell 0.7% after shedding as much as 1.5% to its lowest since September 6, taking its cue from the US S&P 500, which suffered its ninth loss in 11 sessions overnight.

President Barack Obama met Republican and Democrat leaders in Congress but reiterated in a speech that he would not give in to Republican demands to roll back his healthcare programme in exchange for reopening the government.
The debt ceiling is far more important than a partial US government shutdown, which began on Tuesday, since it could lead to an unprecedented default by the United States, an outcome the market assumes is unthinkable.
BNP Paribas analysts said it was increasingly possible that the standoff in Washington would continue until the debt ceiling deadline on October 17.
"Market reaction is likely to intensify going into that date however, with the dollar extending its slide versus yen, Swiss franc and the euro," they wrote in a note.
"The silver lining for the dollar is that it is already trading at a sizeable discount relative to short-term rates, suggesting that there will be plenty of scope for the dollar to rally on any positive outcome in Washington."

Currency dealers said they suspected that South Korean authorities intervened in the foreign exchange market, buying dollars to push the Korean won off what was its strongest level in more than eight months.
The dollar was also hurt by slower growth in the US services sector in September.
Euro looking up
The euro was steady at $1.36255, not far from an eight-month high of $1.36465 touched on Thursday. The common currency was also aided by the European Central Bank's apparent lack of concern over the euro's recent strength and better-than-expected euro zone data.
"The euro has become an island of stability in global asset markets ... Peripheral yields are higher and more stable than in the US and equity markets keep outperforming," Citigroup said in a report.
"However, we would emphasise the euro's rally as a function of improved capital market conditions, rather than fundamentals, and expect it will be fragile if these capital markets conditions change."
Against a basket of major currencies, the greenback was near an eight-month trough.
