TOKYO, June 17 (Reuters) - Japanese government bond (JGB)

yields fell on Wednesday after a slump in crude oil prices eased

global inflation concerns ahead of the U.S. Federal Reserve

policy decision.

Here are a few details:

* The benchmark 10-year JGB yield fell 5

basis points (bps) to 2.595%. Yields move inversely to bond

prices.

* The 20-year JGB yield slid 5 bps to 3.485%.

The 30-year yield sank 7 bps to 3.705%.

Meanwhile, the two-year yield, the one most

sensitive to Bank of Japan policy rates, decreased 2 bps to

1.385%. The five-year yield fell 5 bps to 1.860%.

* Oil prices inched lower on Wednesday, extending the

previous session's declines.

* "There may also have been some rebound buying after

yesterday's sell-off, but the main drivers were the drop in oil

prices and the decline in U.S. yields," said Katsutoshi Inadome,

senior strategist at Sumitomo Mitsui Trust Asset Management.

* Investors will be watching new Federal Reserve Chair Kevin

Warsh closely at his first post-Federal Open Market Committee

press conference on Wednesday, focusing on his remarks and any

changes in the Fed's communication. The Fed is widely expected

to keep interest rates steady and remove its reference to an

easing bias.

* The BOJ on Tuesday raised interest rates to a 31-year high

and signalled readiness to tighten further as it focuses on

taming price pressures from the Iran-war-induced energy shock.
