NEW YORK, Dec 4 (Reuters) - Oil slid below $44 a barrel and global stocks sold off on Thursday in response to deep cuts in interest rates in Europe and more dire economic data that added to worries about the depth of a worldwide slowdown.
Yields on euro zone government debt rose from multi-decade lows this week after investors in Europe said the European Central Bank, the Bank of England and the Swedish central bank didn't go far enough when they slashed rates.
But U.S. government debt later rallied on a safe-haven bid in face of the latest batch of dour European and U.S. economic news pointing to a global downturn that could be the sharpest and longest since the downswings in the early 1980s.
The number of U.S. workers on jobless benefits rolls hit a 26-year high in November, while leading U.S. retailers, with the exception of Wal-Mart Stores Inc <WMT.N>, reported lower sales last month.
Adding to the labor-market gloom, a host of U.S. and European companies announced large layoffs, including top U.S. phone company AT&T Inc <T.N>, which is eliminating 12,000 jobs, and chemical maker DuPont Co <DD.N>, which is cutting 2,500.
In Europe, Swiss bank Credit Suisse <CSGN.VX> announced 5,300 layoffs and Japanese broker Nomura Holdings <6501.T> said it would cut 1,000 jobs in London.
"The consensus is looking for a pretty deep recession," said Robert MacIntosh, chief economist at Eaton Vance Corp in Boston. "There are going to be a lot more (layoffs) and we can barely see the tip of the iceberg."
Wal-Mart's gain was overshadowed by other corporate news, including a deluge of job cuts that signaled the recession is worsening.
Shares of Merck, also a Dow component, fell nearly 4.0 percent to $25.45 after the drugmaker gave a 2009 financial outlook below Wall Street's estimates.
Shares of AT&T <T.N> fell 2.4 percent to $28.38 after it announced plans to eliminate 12,000 jobs and cut its capital spending budget.
"The fact we're seeing these layoffs now tells you that it must pretty darn tight out there for orders and sales," MacIntosh said.

France announced a 26 billion euro stimulus plan for its faltering economy as unemployment rose, the latest European country to open state coffers to fight the downturn.
"We are not in a normal environment. We are facing the most severe recession since 1930s. Once confidence is broken it takes a lot of time and a lot of interest rate cuts to get back," said Franz Wenzel, strategist at AXA Investment Managers, in Paris.
As expected, the Bank of England cut rates by a full percentage point to 2.0 percent and the ECB by 0.75 of a percentage point to 2.5 percent. Sweden's Riksbank bolstered hopes for aggressive cuts, slashing its repo rate by a record 1.75 percentage points to 2.0 percent. But the ECB and BOE cuts failed to satisfy.
"Markets were certainly disappointed by (the ECB's) move today, given what the Riksbank did," said Investec's chief economist Philip Shaw.
The euro rose and sterling traded off a session low against the dollar even after the big European rate cuts.
"It comes back to the theme of proactive rate cuts are seen to be beneficial for the longer-term economic outlook," said Brian Dolan, chief currency strategist at Forex.com in Bedminster, New Jersey.
"Had they done only 50, you probably would see the euro under pressure more than it is," Dolan said of the ECB.

Oil prices were down almost 5.0 percent on demand worries.
"We think the oil market is mostly riding on a wave of worry over weak demand that has taken on a life independent of many actual statistics," said Tim Evans, energy analyst, Citi Futures Perspective in New York.
U.S. light sweet crude oil <CLc1> fell $2.32 to $44.47 a barrel.
