MONEY MARKETS-US bill rates rise, Greek repo market split

By Richard Leong

NEW YORK, Feb 8 (Reuters) - U.S. Treasury bill rates nudged

up on Monday in line with a broad rise in bond yields, as

investors braced for a wave of government debt supply and on a

reduced safety bid stemming from worries over sovereign risks.

The U.S. Treasury Department pledged higher interests on

three-month and six-month bills than those it sold a week ago.

This week's $81 billion refunding and the Congressional

approval to raise the government's debt ceiling had fueled

expectations of more bill supply and higher rates.

The backup in T-bill rates has been muted, however, as a

rise in supply will likely be small, if at all, analysts said.

'This muted response probably fits with Treasury's desire

to keep coupon auction sizes static, which in turn implies bill

supply for the balance of 2010 is unlikely to increase,' said

Alex Roever, short-term fixed income strategist with J.P.

Morgan Securities in New York.

Total T-bills outstanding declined to roughly $1.69

trillion at the end of January from a peak of about $2.07

trillion at the end of August, he said.

While supply has been the main factor in exerting upward

pressure on T-rates, a persistent bid for ultra short-dated,

low-risk investments has kept a lid on rates.

On Monday, the Treasury sold $24 billion of three-month

bills at a high rate of 0.11 percent, the highest in six weeks,

while it auctioned $27 billion of six-month bills at a high

rate of 0.17 percent, the highest since early January.

TOUGHER FUND RULES

Moreover, expectations of stricter rules on money market

funds should stoke T-bill demand in the coming months.

Regulators have sought more safeguards for short-term funds

after the demise of Lehman Brothers during the credit crisis

resulted in the collapse of a huge money market fund.

Under the new rules, regulators would require money market

funds to hold more T-bills and other liquid investments.

On a daily basis, a taxable money fund must keep at least

10 percent of its assets in Treasuries or securities that

mature within one day. On a weekly basis, all money funds must

keep at least 30 percent of their assets in T-bills, certain

agency securities with maturities of up 60 days, or assets that

convert to cash within a week.

Wrightson ICAP estimated taxable money funds would need to

own $300 billion each day in liquid assets and $900 billion

each week at all times.

The research firm said in a note on Monday that the rule

changes, which could become effective this spring, will have

only a limited impact on yields they pay to investors. Many of

the biggest fund operators have been operating under these

stricter guidelines since last summer after the Securities and

Exchange Commission recommended voluntary compliance.

GREEK REPO MARKET

Across the Atlantic, the Greek repo market remained gummed

up on widening sovereign risk fears about some euro zone

states.

While the one-week general collateral rates for core euro

zone issuers such as Germany and Belgium are below Eonia -- a

reference rate for overnight interbank loans in the euro zone,

worries over Greece's fiscal health have pushed up secured

lending rates against Greek collateral for Greek domestic

banks.

'Prices quoted in the Greek repo market are entirely split

between transactions that involve domestic banks and those

which involve only international banks. It's completely

separated,' said Chris Clark, swaps analyst at ICAP in London.

Despite lingering worries over Greece and other European

countries, three-month euro London interbank offered rates

(Libor) fell to 0.60063 percent, the latest in a

series of all-time lows set since the start of the year. For
