By Jason Hovet and Marius Zaharia PRAGUE/BUCHAREST, Sept 30 (Reuters) - Hungary's forint was set for its biggest monthly gain since April 2009 ahead of weekend local elections that could pave the way for the announcement of spending cuts, while Polish bond yields dropped on a cut in supply.
Emerging European currencies, bonds and stocks have mostly firmed this month, led by the forint, and dealers said investor appetite for assets from the region remained strong in the face of worries about public debt in some euro zone countries.
The forint <EURHUF=> shook off the weaker euro/dollar, trading 0.3 percent up at 276.33 to the euro by 1354 GMT, but off Wednesday's four-month highs of 275.3. Hungarian bond yields dipped 4-6 basis points.
"I would not expect the forint to break out of the 276-278 range before the weekend," one Budapest-based dealer said.
In the longer term, however, moves in the forint are expected to depend largely on what the centre-right government pulls out of its sleeve on the 2011 budget after Sunday's municipal election. [
]Ahead of the polls, the government has avoided detailing cuts it might impose next year to meet a commitment to reduce the deficit to a stringent 3 percent of gross domestic product.
"There will not be much excitement before the elections, then we will see what happens, any hard news or figures on what can be expected in the new budget will set the course for the forint," the trader said.
Polish debt yields also dropped 3-4 basis points after the finance ministry said it will offer 7-14 billion zlotys worth of bonds in the fourth quarter, much less than in the third. [
]The Polish zloty <EURPLN=>, the Romanian leu <EURRON=> and the Czech crown <EURCZK=> were flat or a touch stronger.
The crown is trading about half a percent off a 22-month high hit earlier this month, adding about 0.7 percent in September overall. The forint has been the best performing emerging European currency in September with a 3.8 percent rise.
WEEKEND POLL
Hungary's ruling Fidesz party has spooked markets since sweeping April elections by comparing its debt problems with those of Greece and suspending International Monetary Fund aid talks.
"As we expect this to confirm the already announced 3 percent deficit target for 2011, we continue to recommend constructive positions going into this period," UniCredit analysts said.
SEB analysts said the stronger forint has weighed on the zloty, which has dipped 1.7 percent in the past two weeks, also hurt by some cooling of interest rate hike expectations.
Romania announced plans to issue 4.6 billion lei of debt in October, a similar target to this month's, but more than double the amount it actually sold. [
]Analysts expect it to fail to meet its target again due to a self-imposed yield cap of 7 percent, putting pressure on it to accept generally higher yields. --------------------------MARKET SNAPSHOT-------------------- Currency Latest Previous Local Local
