Chase Manhattan Corp. shelved a $500 million debt deal Tuesday because  of eroding conditions in the bond market, sources said. 
Chase had been poised to issue the 10-year global notes since last week.  The market for corporate debt had roared back from abysmal lows, and   investors seemed to be chomping at the bit for bank securities.   
  
But on Monday, the market took a turn for the worse. Spreads-the  difference between corporate bond yields and those of Treasuries-on bank   bonds began to widen as investors grew anxious about the swoon in the U.S.   and overseas stock markets.     
Sources said investment bankers for Chase were hoping to place the notes  at 115 to 118 basis points over Treasuries. As the spreads on bank bond   debt and other corporate debt began to widen on Tuesday, investment bankers   tried to make the price more attractive by offering the notes at 125 basis   points over Treasuries.       
  
Investors, however, failed to bite at that price, meaning it would be  too costly for Chase to sell. 
"Chase tried to get too cute with the pricing," said one bond expert who  declined to be identified. "That deal was too large to be priced so   aggressively. In this market issuers have to price cheaply. Chase didn't,   and shot themselves in the foot."     
Other experts said that Chase was simply caught in the unpredictability  of a capricious market. Chase planned to issue the debt because conditions   had become too favorable not to, sources said. As market conditions   improve, Chase is likely to reoffer the deal, they said.     
  
A Chase representative declined to comment.
Placing a deal on Tuesday also proved difficult for BankBoston Corp.,  which brought to market $250 million of subordinated debt. Investment   bankers planned to offer the deal at 150 to 155 basis points over   Treasuries, but were forced to sweeten the price by 30 basis points to   attract investors.       
The unplugging of the Chase deal and BankBoston's difficulty in placing  its debt could dampen banks' enthusiasm for issuing debt. 
Bank bond issuance had hit rock bottom in November, when only $5.3  billion in subordinated and senior debt came to market, according to   Securities Data Co. But market experts said they were optimistic that that   trend was likely to change.     
  
Commercial banks issued $7.9 billion of subordinated and senior debt in  October and $10.8 billion in September. But "one cannot expect the market   to glide back to where it was," said bank bond analyst Eric J. Grubelich of   Keefe, Bruyette & Woods Inc. "There is going to be some wind sheer along   the way."       
Still, many bond analysts expect bank issuance to increase because the  bond market is improving, and funding needs for some banks have become more   pressing.   
"We are expecting more supply in the next couple of weeks," said bank  bond analyst Katherine Rossow of Chase Securities Inc. Bankers "do not have   enough confidence in the long-term market to postpone issuing debt. Why   take the risk that something could go wrong with the economy next year?"     
Joseph J. Labriola, head of the corporate bond research department at  PaineWebber Inc., said that many banks need to replenish regulatory debt   that is being extinguished because of amortization.   
When debt amortizes it tends to remain on a bank's balance sheet, but  ceases to qualify as total capital, a cushion that banks need during   economic hardship.   
"There was a lot of issuance of seven- and 10-year paper in 1991, 1992,  and 1993, which is or is about to amortize as we approach 1999," Mr.   Labriola said. "From a regulatory perspective, it is important that banks   pre-fund that debt as it rolls off."     
It has become more pressing for some banking institutions to raise  capital because of the rash of mergers and acquisitions, the analyst added. 
Banks held off issuing debt primarily because of the meltdown in the  capital markets. Turbulence in the global economy forced bank bond spreads   to levels that not seen since 1994. Investors also dumped securities   because economists were warning of a recession in 1999.     
"There is no question that investors were boycotting the market," Mr.  Labriola said. "However, in the last several weeks we have seen a lot of   finance companies and industrial companies issue debt cheaply, and   investors have been running to grab it. Banks likely will follow with deals   next year."
