Demand for all the but the shortest-maturity Treasuries -- some of which rallied sharply -- collapsed again today, lifting the 30-year bond's yield to its highest level since mid-February.

Several factors were at work. Apprehension about how much the

Fed may raise the short-term interest rate it controls in the months ahead continues to make investors shy away from bonds in general. The

Treasury Department

conducted a buyback operation that supported prices early in the session, but when it was finished, some dealers may have moved to sell issues they had failed to sell to the Treasury. In addition, there are large corporate new bond issues in the offing that will compete with Treasuries for investor dollars. And commodity prices continue to move higher, with oil once again breaching $30 a barrel today.

The benchmark 10-year Treasury note fell 12/32 to 99 22/32, lifting its yield 5.5 basis points to 6.542%. The 30-year Treasury bond fell 20/32 to 100 8/32, lifting its yield 4.6 basis points to 6.230%, the highest since Feb. 16.

In part, negative price action in the Treasury market has to be seen as a simple function of the fact that the Fed isn't finished raising the

fed funds rate, said Jim Glassman, an economist at

Chase Securities



Tuesday, the Fed hiked its funds rate to 6.5% from 6% and strongly hinted that additional hikes are forthcoming.

Long-maturity Treasury issues rallied that day, in a move that was explained as reflecting confidence that the Fed's actions on short-term rates would have a beneficial effect on inflation over the long term, making long-term investors willing to settle for lower yields.

Today's action (and

yesterday's) exposes that explanation as so much bunk, Glassman says. "No matter what they tell you about how the markets love tightening because it makes them comfortable that the Fed is fighting inflation, when they raise rates, rates go up," he said.

The fact that people disagree about how much higher the funds rate will go means market rates have to err on the high side, Glassman added. "At the end of the day what we know is that rates are going higher, and that's the problem."

Today, that general unwillingness to own bonds manifested itself somewhat paradoxically. It sent money cascading into the Treasury bill market, deeply depressing yields there. For example, the three-month Treasury bill, which ended yesterday at a yield of 6.041%, ended today at 5.915% after trading at a yield as low as 5.847%.

The action is unusual because normally, bill yields stay closer to the fed funds rate. In this case,


managing analyst Ken Logan said, investors are willing to pay up for Treasury bills in order to avoid owning longer-term instruments, whose prices fall further when their yields rise.

Investors are "hiding out, expecting higher rates down the road," Logan said. "That's sending a torrent of money into the bill market, which deprives the rest of the market of buying interest. Cash is king right now."

Meanwhile, the Treasury Department completed its fifth buyback operation today, accepting dealer offers on $2 billion of 30-year bonds issued from 1985 to 1989. But the market weakened after the 11 a.m. EDT operation, Logan said, because at least several dealers were left holding bonds they had expected to sell. "You had to be very aggressive in pricing to have orders taken," he said. "A lot of shops didn't sell anything."

Finally, the

Federal Open Market Committee released the

minutes of its March 21 meeting. The most interesting disclosure was that the committee took into account "somewhat unsettled financial markets" in its decision to hike the funds rate by 25 basis points rather than 50 at that meeting.
