* Euro hits 11-wk low vs dollar; falls vs yen, Swiss franc
* Euro breaks below barriers at $1.30 before recovering
* Contagion fears weigh as peripheral bond spreads widen (updates prices, adds quote on ECB)

LONDON, Nov 30 (Reuters) - The euro slid to nearly 11-week lows against the dollar and fell on the yen, Swiss franc and sterling on Tuesday as a rescue deal for Ireland failed to quell worries that other euro zone countries may need help.
The euro fell 1 percent against the dollar, breaking through reportedly strong option barriers to take it below $1.30.
A lack of confidence the Ireland deal would contain the debt crisis caused the premiums investors demand to hold Spanish and Italian sovereign bonds over German debt to jump to euro lifetime highs. Yields on Portuguese, Irish and Belgian bonds also widened. [
]"At the moment there is no confidence that any of these (peripheral) countries can effectively fund," said Adrian Schmidt, currency strategist at Lloyds.
"Until we get some sort of market appetite for peripheral debt these worries will continue to weigh on the euro," he said, adding he believed the currency could fall as low as $1.25.
The euro <EUR=> fell to $1.2979 on EBS trading systems, its lowest since Sept. 16, before modestly recovering to $1.3013, with traders saying model funds and other investors were buying at lower levels.
It stayed well below its 200-day moving average, currently around $1.3127, having closed beneath it on Monday to signal a bearish trend ahead.
Traders said the ease with which the euro had broken key levels in recent days reflected the extent of negative sentiment towards the single currency, which has lost around 9 percent against the dollar since its peak earlier this month.
Risk reversals showed a sharp increase in the premium charged for buying euro puts -- bets on the currency falling -- over euro calls, with the one-month euro/dollar 25-delta <EUR1MRR=ICAP> trading at around 2.45 for euro puts. This is up from 1.95 on Monday and nearing highs hit in June close to 3.0.
The dollar gained broadly, hitting a two-month high of 81.346 against a currency basket <.DXY>, lifted by safe-haven flows and recent evidence of an improving U.S. economy.
BEARISH SENTIMENT
The latest positioning data from the Commodity Futures Trading Commission showed speculators going net short on the euro for the first time since Sept. 14 [
], but traders saw scope for more adjustment."With euro positioning nowhere near any extreme there is more scope for downside over the coming sessions," a London-based trader said. "Flows retained a negative euro bias with macro funds selling euro cash and positioning to the downside via options."

The single currency slid to 1.2972 Swiss francs <EURCHF=R>, 108.90 yen <EURJPY=R>, and 83.665 pence against sterling <EURGBP=D4>, all more than 10-week lows.
"The most liquid form to express a negative view on the euro zone now is through the euro," said Ray Farris, currency strategist at Credit Suisse. "One can see a fire stop if the European Central Bank decides to allow banks continued access to its balance sheet when it meets on Thursday."
The ECB is widely expected to keep rates on hold and sources say it could extend banks' access to unlimited three-month funds beyond January. [
].That could help ease some of the funding strains that the banks in peripheral euro zone economies are currently facing.
The higher-yielding Australian dollar <AUD=D4> also fell to an eight-week low of $0.9566 as worries about Chinese tightening hurt risk appetite. (additional reporting by Anirban Nag)
