SEOUL, Sept 29 (Reuters) - South Korean treasury bonds fell further on Tuesday, with most debt investors growing cautious ahead of major data and central bank policy statements.

The nation's latest monthly output, trade and inflation data are due out later this week while the central bank will issue a bi-annual policy report on Wednesday.

Robust business confidence data and rebounding imports spurred hopes of sustainable economic recovery but a sizable treasury bond buyback deal helped the yields end off their daily lows.

"We had every reason to stay back today, with key data impending and the central bank issuing policy-related statements ahead of the holiday," said Jung Sung-min, a fixed-income analyst at Eugene Futures.

The minutes from the Bank of Korea's August policy meeting released after the market closed showed that one board member proposed consideration of a policy shift last month while another saw a need to curb excessive investor risk appetite.

The benchmark five-year treasury bond yield rose 3 basis points to 4.84 percent while December treasury bond futures fell 3 ticks to end at 108.63, rewinding many of their earlier 15-tick losses.

The three-month certificate of deposit rate rose 1 basis point to 2.74 percent, the highest since February, while one-year interest swaps also rose for a second day.
