* New platform launch would ease criticism of local market
* But dealers worry planned July launch is too soon
* Ministry says launch date achievable
By Jason Hovet
PRAGUE, Feb 16 (Reuters) - Czech bond dealers have cautiously welcomed Finance Ministry proposals to overhaul the secondary bond market to raise transparency, but some doubt that the changes can be implemented by July 1 as planned.
The ministry aims to switch the domestic bond market on that day to the electronic trading platform MTS, already used by 13 European Union states, to bring greater visibility to a market where 80 percent of state debt is sold.
The International Monetary Fund last year criticised the current bond market system for opaqueness.
The move will shift dealers to a market-making system in which market makers' performance will be regularly evaluated and rewarded. It also sets up a unified, real-time market after market making dried up during the financial crisis.
Czech price quotes can often vary widely, so dealers said the change should bring more clarity and help attract more foreign investors. But they also said the timeframe to get the system operational may be too tight.
"It should increase liquidity and better visibility in the market," said Ivan Varga, Komercni Banka's head of treasury. "For local and mainly foreign investors, this was the weakest point of the local market."
Secondary market trade volumes have run between 45-55 billion crowns in recent months, according to Prague Stock Exchange statistics. Gross issuance on domestic and foreign markets reached 216.2 billion crowns ($12 billion) last year.
The ministry started talks with market participants last week on rules for market makers, whose job is to help keep bid and ask prices firm and buy and sell paper. Those picked as market makers would have access to primary auctions, which are currently open to 11 banks.
Participants and the ministry said that while nothing has been agreed so far, some of the possible rewards for banks that take on market-making roles could be discounts in primary debt auctions for the best-performing market makers, and access to private placements among other things.
The ministry's debt department head Petr Pavelek also said the ministry's presence on the secondary market was up for discussion. Its practice of directly selling bonds off its books -- which it stopped at the end of 2010 -- had irked some market players.
He said the ministry was also considering raising the proportion of bonds on offer in the competitive round of two-round tenders from the current 85 percent.
TECHNICAL LAUNCH WORRIES
Dealers said the technical aspects are still an open question, leaving little time to resolve any problems there. Five of the six primary dealers contacted by Reuters had reservations about the July launch target.
"Definitely others are not sure. There are many things to be solved (from the technical point of view)," PPF Banka dealer Josef Bednar said. "The July 1 date is too optimistic."
The ministry said last week that all 11 primary dealers and one foreign group have expressed an interest in market making.
The ministry's Pavelek said talks would be ongoing and that MTS officials would soon start one-on-ones with banks.
"The technical, legal and regulatory aspects of the project will be further discussed and refined, in order to ensure that the specific needs of the Czech bond market are appropriately addressed," he said. "But we believe July 1 is achievable." (Editing by Hugh Lawson)
