LONDON, Aug 27 (Reuters) - The government bonds of Slovakia, the euro zone's most recent entrant, became the highest-yielding in the currency bloc this month and analysts reckon this is set to continue.
Without much fanfare, the country's barometer 10-year government bond <SK10YT=RR> pipped Ireland's as the highest-yielder versus the euro zone's benchmark German Bund <EU10YT=RR>.
Lack of liquidity in a small capital market, competition from covered bonds which are centre stage as the European Central Bank mops them up, and turbulence that often greets new euro zone entrants, have all conspired to give Slovak bonds a hard time.
On Thursday, Slovak bonds yielded 162 basis points more than Bunds on a bid price basis, while Irish 10-year gilts <IE10YT=RR> yielded 155 bps over German paper.
It means the premium investors demand to hold Slovak government bonds rather than safer haven Bunds is higher than for any other euro zone member state and makes funding relatively more expensive for the central European issuer.
This happened despite Slovakia's credit risk being lower than that of Ireland.
According to data from CMA DataVision, a monitor of credit default swaps (CDS), Slovakia's risk of defaulting within five years is 6.2 percent versus Ireland's risk of 12.7 percent. Ireland joined the euro in the first wave of entrants in January 1999.
"It's a curse that can befall sovereigns when they first join the euro that rather than harmonise yields with German Bunds, the yield spread stays or goes wider, as happened for Portugal for a while after 1999," said Marc Ostwald, a bond analyst at Monument Securities in London.
"It's doubly unlucky for Slovakia which joined at precisely the time when bond yield spreads blew out in Europe at the height of the global credit crisis," he added.
On Monday, Slovakia managed to issue 461 million euros of four-year bonds -- by far the largest bond auction for the sovereign since it joined the euro zone in January - as bidding was frantic. [
]But the same day Daniel Bytcanek, chief of Ardal, the Slovak debt management agency which issued the bond, told Reuters he considered the yields which the issuer accepted in the auction at "up to 4 percent are totally at the edge of acceptable levels". [
]Bytcanek said yields demanded by banks should decline because spreads (over Germany) of comparable debt in other euro zone countries had declined but Slovakia's were still at levels the agency considered too high.
Slovak yields have been falling since June, but more slowly than other so-called peripheral debt yields such as Ireland's amidst an equities rally, optimism about an end to recession in parts of the euro zone, all of which led to an unwinding of safe haven trades from German Bunds, favouring peripheral debt.
"There has been a surge of interest to buy peripheral debt in the past few months which benefited the likes of Irish gilts," said Ostwald, "but Germany wasn't the only loser in this, so too was a less liquid market like Slovakia."
LIQUIDITY IS KEY FOR PERIPHERAL DEBT DEMAND
The average size of an Irish government bond now stands at around 6-7 billion euros while for Slovakian bonds it is closer to 2 billion euros.
Analysts said it can take years for a sovereign issuer to develop the capital market depth and liquidity that can drive yield spreads narrower.
"Slovakia is still pretty much beyond the radar of many investors given the very tiny bond market relative to euro zone peers," said David Schnautz, a bond analyst at Commerzbank in Frankfurt.
"Negative spillover effects of the still not 100 percent clear situation for the admission to the euro of some of Slovakia's neighbours in central and eastern Europe may also hinder Slovakian government bonds," he added.
Schnautz said the government bonds of smaller euro zone countries may be facing competition from covered bonds.
"Unfortunately for Slovakia, the covered bonds arena is in the limelight due to the European Central Bank which has been buying up covered bonds since early July," he said.
The ECB reported earlier on Thursday it has bought a total of nearly 8.5 billion euros of covered bonds under its programme. [
]"It is difficult to determine precisely what this huge yield differential over the other euro-sovereign issuers is made up of. Looking at the CDS for guidance, the credit risk of Slovakia is lower than that of Ireland, closer to that of Italy," said Peter Chatwell, a bond analyst at Calyon in London.
He said debt issuance in the summer attracts a liquidity premium that issuers tend to have to pay.
"The liquidity premia which Slovakia suffered earlier this week looks quite brutal, but the holiday season is still in full swing...Had Slovakia been issuing the same bond a couple of weeks later, they would have found demand at a lower yield," he added.
