LONDON/PRAGUE, June 3 (Reuters) - The Czech Republic sold a benchmark 10-year eurobond on Tuesday worth 2 billion euros ($3.1 billion), more than expected, which traders said could revive the weak domestic market.
The paper will bear a coupon of 5.0 percent and its issue marks the Czech return to the international debt market for the first time since 2005 as domestic borrowing costs rise.
The eurobond was priced to yield mid-swaps plus 25 basis points, at the lower end of a 25-30 basis-point range.
Orders reached just under 3 billion euros, an official at one of the banks managing the sale said. The size of the deal is double the initial finance ministry's intention to raise around 1 billion.
"The size is bigger than expected. But I could imagine even better pricing ... 5-10 (basis) points lower," said Ondrej Vavra, portfolio manager at PPF Asset Management in Prague.
The paper was priced 68 basis points over the January 2018 German Bund <0#DE113534=>.
The issue's swap spread is 15 basis points higher than in Italy or Greece, Ceska Sporitelna said in a report ahead of the final pricing.
Swap spreads on comparable papers in Hungary <0#HU028481071=> and Poland <0#PL021031429=>, stand at 55.7 and 44.9 basis points, respectively, according to Reuters data.
The Czech domestic 10-year bond <CZ10YT=RR> traded to yield 5.097/045 percent, 69 basis points above the corresponding Bund and 45 basis points above local swaps.
Czech domestic spreads have risen in the past months, adding support to the ministry's plans to issue abroad.
The ministry has said a eurobond issue would be hedged in order to prevent upside pressure on the crown currency.
Barclays Capital and Deutsche Bank managed the sale.
NO MORE EUROBONDS
The Finance Ministry had no immediate comment on the issue but traders said it was not likely to tap foreign markets with another Eurobond issue this year, although it still has room in its debt strategy seeing up to 89.9 billion crowns ($5.64 billion) worth of foreign borrowing.
"The situation would have to get significantly worse on the domestic market to issue another eurobond, which I do not expect after this successful eurobond issue," said Komercni banka trader Dalimil Vyskovsky.
The ministry has set a 165-185 billion crown full-year medium and long-term borrowing target on both domestic and foreign markets.
Traders also said local spreads could narrow slightly as the state will have a lower need to place debt after the latest Eurobond placement.
The Czechs have issued two eurobonds so far, a 10-year note <CZ019495752=> due 2014 and a 15-year <CZ021515329=> note due 2020.
The Czech Republic is rated A1 by Moody's Investors Service, A by Standard & Poor's and A+ by Fitch Ratings.
