* Euro holding just above 11-week lows, more downside seen
* S&P says may cut Portugal's credit ratings
* Market wants to see more pre-emptive action
By Charlotte Cooper
TOKYO, Dec 1 (Reuters) - The euro inched up on Wednesday after a drubbing the previous day but remained near 11-week lows against the dollar in a market waiting to see what European policymakers will do next to contain worries about euro zone debt.
The euro suffered yet another setback as Standard & Poor's threatened to cut the credit ratings of Portugal, but then stabilised above the previous day's low of $1.2969 <EUR=>, a level not seen since mid-September.
Still, while small recoveries are not ruled out few expect that its trials are over, with downside targets now at about $1.2800 and then its August lows around $1.2600.
The euro was also near 11-week lows against the yen after falling 1.8 percent on Tuesday, and 10-week lows against sterling after premiums on Spanish and Italian bonds over German debt rose their highest in the euro's lifetime.
Analysts said the market was looking for more pre-emptive action by policy-makers in the region after a rescue package for Ireland at the weekend, as pressure in the euro zone bond market was widening to more countries including Belgium.
"The general feeling is that this is a mess that is not going to be easily escaped," said Robert Ryan, a FX strategist at BNP Paribas in Singapore.

Citing uncertainties stemming from the risk of Portugal having to seek international financial aid, S&P put the country's A-minus rating on review for possible downgrade. [
]S&P's warning came after Ireland secured an 85 billion euro ($110 billion) bailout package on Sunday, seven months after Greece was thrown a lifeline to tackle its debt problems.
Markets worry that other debt-ridden euro zone countries such as Portugal and Spain will also need aid and if so whether the region can really afford it. Portugal's prime minister said it is not facing any pressure to ask for a bailout and does not need any such help. [
]"You really need some aggressive action from the authorities in Europe to try and calm nerves and that's really the key at this stage," said Greg Gibbs, a strategist at RBS in Sydney.
Euro zone's debt woes are also raising suspicions that European banks could find it costly to access dollar cash, if not impossible.
While dollar interest rates such as three-month LIBOR <USD3MFSR=> have risen only slightly in the past few days, euro/dollar basis swap spreads have risen sharply in recent weeks <EURCBS> in a possible sign that some euro-zone banks are trying to raise dollar cash through swaps.
The one-year spread, now over 50 basis points, is above the peak it hit in the wake of Greek debt crisis in May, though still far below the peaks after the Lehman Brothers collapse in 2008.
The next event in focus is a European Central Bank meeting on Thursday that analysts say has taken on added significance as confidence in the region has deteriorated.
Investors will be looking for comments on how the ECB can help address growing anxiety in the credit and currency markets, and Ryan at BNP said the ECB could eventually be forced into making more government bond purchases.
On Wednesday, though, the euro edged up to $1.3020 after languishing below $1.3000 for much of the session, with support at about $1.2795, a 61.8 percent retracement of its June-November rally, and resistance at about $1.3060.
The euro has fallen 9 percent from its November high of $1.4283 and shed 7 percent in November alone, the biggest monthly fall since May.
Momentum indicators such as stochastics signal its fall is well and truly stretched, building the chance of a rebound, but chartwise scope for a recovery, at least in the near term, is seen a limited to $1.3060-$1.3100.
It fell to 108.33 yen <EURJPY=R> on Tuesday, a level last seen on Sept. 15, the day Japan intervened to stem yen strength, and plumbed a record low versus the Australian dollar at about A$1.3515 <EURAUD=R>. It was at 108.65 yen on Wednesday.
The dollar has been a beneficiary of the euro's problems, which has helped fuel a retrenchment in investor confidence, denting higher-yielding currencies such as the Australian dollar.
The dollar index <.DXY>, which tracks the greenback's performance against a basket of other major currencies, rose to its highest since Sept. 20 on Tuesday at 81.444 and was stable on Wednesday just below its 200-day moving average of 81.78.
The yen has fared the best in the past 24 hours as investors have unwound yen-funded positions in higher yielding currencies and Japanese exporters bought the yen.
The dollar dipped to 83.38 yen <JPY=>, its lowest level in a week and retreating a full yen from a two-month high of 84.41 yen hit on Monday.
The rise in the yen has prompted Japanese margin traders -- known collectively to be contrarian -- to increase their net yen-selling positions to near a record high, putting a brake on the yen's rise. [
]Meanwhile the Australian dollar dipped to its lowest since late September at $0.9536 after Australian GDP data showed the economy grew less than expected in the third quarter and suggested there was no urgency for the central bank to tighten interest rates again soon. [
