NEW YORK, July 30 (Reuters) - Bond investors were the most bullish on U.S. longer-dated government debt since late May ahead of a Federal Reserve meeting where policy makers are widely expected to lower interest rates for the first time in a decade, a J.P. Morgan survey showed on Tuesday.
The share of investors who said they are "long" or hold more longer-dated Treasuries than their portfolio benchmarks exceeded those investors who said they are "short" or hold fewer longer-term government debt issues than their benchmarks by 13 percentage points.
This was the highest level of net longs since May 28, J.P. Morgan said.
Investors were net long by 5 percentage points a week earlier. (Reporting by Richard Leong Editing by Susan Thomas)
