* June year-on-year headline inflation unchanged from 4.6 pct May level
* Inflation seen peaking by August
* Slovak rates seen flat after ECB tightening

BRATISLAVA, July 10 (Reuters) - Slovakia's annual inflation rate remained in June at the 4.6 percent level reached in May, which was a 20-month high, as food and fuel prices continued to exert pressure.
Analysts said they expected price growth to peak in July or August.
Consumer prices rose by 0.4 percent month-on-month in June, the Statistics Office said on Thursday [
].Analysts had expected prices in Slovakia, which will join the euro zone on January 1. 2009, to rise 0.3 percent on the month and 4.6 percent on an annual basis in June.
"Food and fuel prices remain inflation's key drivers," said Maria Valachyova, senior analysts at Slovenska Sporitelna.
Those two factors have spurred inflation across central and Eastern Europe, although Czech consumer prices grew at only half the pace predicted by the market -- 0.2 percent month on month -- in June, lowering chances of a central bank rate hike.
Romanian prices rose 0.3 percent to an annual rate of 8.5 percent.
Slovak food and non-alcoholic beverages rose by 0.7 percent on the month, a slightly slower pace than May's 1.0 percent. They were up 9.0 percent on the year.
"The general picture remains unchanged -- inflation is still driven mainly by cost-push factors," said Piotr Matys, analyst with 4Cast in London.
Analysts saw no major demand-led inflation risks building up because the firming crown currency was still tightening monetary conditions.
"Inflation should, in the nearest months, move closer to 5.0 percent, with a peak coming likely in July-August," said Silvia Cechovicova, analyst with CSOB Bank. She said risks remained on the side of food and oil prices.
The crown has gained 11 percent against the euro since January, boosted by expectations of a strong final conversion rate, which was set, as widely expected, at its central parity rate of 30.126 per euro on Tuesday.
The Slovak central bank left its key two-week repo rate flat at 4.25 percent for the 14th consecutive month in June and analysts saw rates staying flat this year after the European Central Bank's hike last week.
The ECB raised interest rates by 25 basis points to 4.25 percent, their highest level in nearly seven years, but dimmed the prospect of further moves, as euro zone growth looks set to falter despite soaring inflation.
