NEW YORK, April 5 (Reuters) - The euro rose to an 11-month high against the yen and neared a recent five-month peak against the dollar on Tuesday on expectations of rising euro zone interest rates that could keep the single currency supported in months ahead.
Hedge fund adviser Medley Global Advisors said in a report that the European Central Bank was poised to raise rates on Thursday -- as expected -- and build in room to tighten further. The report helped the euro recover from earlier losses knocked by a ratings downgrade of Portugal. See [
].Expectations of rising UK rates also got a lift after strong service sector data drove sterling higher. Rate differentials have moved against the dollar in recent weeks after comments by Federal Reserve officials signaled an uncertain outlook for U.S. monetary policy.
Going into Thursday's ECB meeting, the euro will likely stay in its recent range, capped by resistance near $1.4280, which marks the November high and a trendline drawn from the July 2008 record high. Traders expect the euro eventually to take out that resistance and rise toward $1.50.
"In the months ahead, we're likely to see more hawkishness out of the ECB than the Fed," said Samarjit Shankar, managing director of global FX strategy at BNY Mellon in Boston.
In a sign of divergence over the outlook for U.S. rates, the minutes of the Fed's March meeting released on Tuesday showed some policymakers believed they would have to hold to an easy monetary policy course beyond this year, while a few said the central bank should move to tighter conditions before year-end.

Against the dollar, the euro was flat at $1.4221 <EUR=>, just below a session high of $1.4245 and near a five-month high touched on Monday.
Expectations for a 25-basis-point rate hike by the ECB on Thursday have supported the euro in recent weeks, with reported bids from $1.4140 seen limiting losses.
CHINA HIKES
Moody's cut Portugal's sovereign debt rating by one notch, saying debt problems on the euro zone periphery may prevent the ECB from raising rates an anticipated three times this year. See [
]Credit Suisse in a note to clients said while peripheral uncertainty clearly remains, with Portugal likely needing aid, "Spain, the peripheral economy of real systemic importance, has seen borrowing costs steadily decline this year, almost completely decoupling from dynamics in Portugal.
"With systemic risks fading, ECB tightening is likely to keep yield support for the euro elevated." The firm expects the euro to overshoot its three-month forecast of $1.44 and rise to $1.50 in 12 months.
The Australian dollar traded down as low as $1.0289 <AUD=D4>, retreating further from its post-float high touched on Monday. The Australian dollar was floated in December 1983.
China hiked interest rates by 25 basis points, the fourth rate increase since October [
]. Given strong trade links, the Aussie can be the most sensitive to tightening moves by China. The aussie last traded down 0.2 percent at $1.0339. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^For a graphic on Chinese interest rates click on http://r.reuters.com/veh88r ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
An unexpected leap in UK services sector activity to a 13-month high buoyed the pound, which rose as much as 1 percent versus the euro as the market moved closer toward pricing in a UK rate hike in June. [

A 200-day moving average at around 83.55 is now seen acting as support. (Additional reporting by Nick Olivari; Editing by )
