NEW YORK, Oct 27 (Reuters) - The dollar and yen gained on Monday as a slide in world stock markets and fears of a global recession prompted investors to abandon risky assets, but U.S. stocks bucked the downward trend on Verizon's good results.
Pessimism about the deteriorating global economic outlook weighed on investors around the world, driving oil prices to a 17-month low below $62 a barrel at one point and keeping alive a modest safe-haven bid in U.S. and euro-zone government debt.
The dollar climbed to its strongest level against the euro in about 2-1/2 years, while the yen hovered near 13-year peaks against the dollar. The yen also rose to its highest since May 2002 versus the single euro zone currency despite concern by G7 finance officials about its excessive volatility.
Both the dollar and yen have been the biggest beneficiaries of global capital flows as investors unwind carry trades, which use the low-yielding Japanese currency to buy everything from higher-yielding currencies to stocks and commodities.
"This is a continuation of deleveraging and unwinding of risk that has been happening the past week and this has benefited the yen and the dollar," said Omer Esiner, senior market analyst at Ruesch International in Washington.

Fear of a global recession remained high in other markets, too, helping push the yield on two-year bunds <EU2YT=RR> to its lowest in three years.
The price of U.S. government debt, which moves in the opposite direction of yield, were capped by a slight improvement of sentiment in short-term funding markets, helped by a Federal Reserve program to buy commercial paper.
