Interest rates are headed up next year, according to economists  contacted for the latest American Banker yield and rate survey. 
The view of half the 10 business economists is that the Federal Reserve  will probably have increased short-term rates at least one-quarter   percentage point by this time next year.   
  
A couple think the central bank may need to ratchet up rates by a half  or even three-quarters of a point to brake the economy and subdue the   inflationary potential of a tight job market.   
"The Fed almost always has to go further than expected to get the job  done," said Kenneth T. Mayland, chief economist at KeyCorp, Cleveland. "And   we have a lot of economic momentum right now."   
  
The rising-rate scenario presumes that Asia's financial crisis will not  slow the U.S. economy enough to offset the wage pressures being generated   by a 4.6% unemployment rate, the lowest in a generation.   
Mr. Mayland said he thinks the federal funds rate, which is charged for  overnight loans of bank reserves, will be 6.25% by the fourth quarter of   1998, up from the current target of 5.5%. BankAmerica Corp.'s chief   economist, John O. Wilson, said he expects a half-point increase, to 6%.     
Others, like William Dudley of Goldman, Sachs & Co., said they think the  Fed may only tighten credit conditions a single notch, or one-quarter   point, while five of the 10 contacted think the central bank will stand pat   on rates next year.     
  
"I think the Asian impact will turn out to pretty small, around a  quarter percentage point of GDP," Mr. Mayland said, "and I wonder if it   will even measure up to that."   
"We're seeing lower bond yields today because of Asia," he said. "That  probably means we will build a few new homes and sell a few more new cars-   and these are offsets to any slowdown effect."   
People will have more discretionary income, he suspects. "Having to  spend a little less next year buying a Sony VCR made in Malaysia, means   having a little more to spend going to the movies or the mall," he said.   
"Any resources released are going to be readily snapped up elsewhere in  an economy that the Fed might well describe as beyond full employment," Mr.   Mayland said.   
  
Indeed, 1998 will be "a dicey year" for the Fed, said Wayne M. Ayers,  chief economist at BankBoston Corp. 
"To be sure, we expect the economy to slow over the course of the next  year," he said. "But unless this slowdown is evident sooner rather than   later, we expect the Fed will be forced to risk a modest uptick in rates in   early 1998."     
But others are not as sanguine about the economy's vigor.
"Despite U.S. economy's recent solid advance, other factors will far  outweigh the current economic strength," said John Lipsky, chief economist   at Chase Manhattan Corp.   
In a revised 1998 forecast titled "Good-Bye Goldilocks," Mr. Lipsky said  he expects U.S. economic growth to slow to little more than 1% and consumer   price inflation to drop to about 1.5%, raising chances that the Fed will   reduce-not raise-rates.     
The title of his forecast refers to the well-balanced business  conditions of recent years. Economists labeled this the Goldilocks economy-   not too hot and not too cold.   
"The 1998 outlook represents the end of the Goldilocks phase of the U.S.  expansion," Mr. Lipsky wrote, "encompassing solid growth in output and   profits, high rates of capacity utilization, plus low and stable   inflation."     
"Superseding the Goldilocks economy," he said, "will be a more  conventional combination of sluggish growth, modestly rising unemployment,   and falling inflation."   
At the same time, Mr. Lipsky warned, his outlook is subject to change  because "the Asian outlook remains highly uncertain and could turn out to   be more troublesome than has been assumed."
