TOKYO (BLOOMBERG) - Japan's Government Pension Investment Fund (GPIF) made a record cut to the weighting of Treasuries in its portfolio last fiscal year as the world's safest asset led a global debt sell-off.

GPIF, the world's biggest pension fund, slashed United States government bonds and bills to 35 per cent of its foreign debt holdings in the 12 months through March 30, from 47 per cent previously, according to an analysis by Bloomberg of the latest data.

The rebalancing comes with the fund now over a year into a new investment plan that has reduced dependence on Japanese government bonds and shifted focus toward higher returning equities and overseas debt. Bloomberg's analysis indicates the shift came largely through boosting holdings of European sovereign bonds, rather than selling Treasuries into a falling market.

While GPIF offers little commentary on annual changes in its portfolios, even small adjustments reverberate through world markets given its total investments of about US$1.7 trillion (S$2.3 trillion). Some strategists suggested the pension giant may have sought to trim Treasuries because of an extended period of underperformance. Others said this could have been incidental as it moved to reduce risk by aligning weightings with global indexes.

To be sure, GPIF's Treasury holdings had shot up in the year earlier, particularly in shorter maturities, just as it was mulling the new investment plan. This offers yet another reason - that extra funds had only been parked temporarily in US bills and notes as a substitute for cash before the fund settled on more permanent allocations.

Whatever the motives may have been, GPIF made a 7.1 per cent return on overseas debt last fiscal year, versus 5.4 per cent for FTSE Russell's World Government Bond Index excluding Japan, which it measures performance against. That represents the strongest result in four years versus the benchmark.

FTSE Russell's weighting for Treasuries was around 38 per cent as at the end of June, including Japanese debt.

GPIF's allocations for French, Italian, German and British bonds all increased by at least 1.7 percentage points in the 12 months through March. Purchases of these securities totaled 5.72 trillion yen (S$70.6 billion) after adjusting for fluctuations in exchange rates and bond prices, Bloomberg's analysis found.

While the weighting for US bonds fell, GPIF still added about 1.1 trillion yen worth of Treasuries to its holdings last fiscal year, after adjusting for currency fluctuations and bond returns, according to Bloomberg's analysis. That took its hoard to about 17.5 trillion yen.

Under its five-year investment plan that took effect in April last year, GPIF aims to split its portfolio evenly between stocks and bonds, with these two asset classes then divided equally between domestic and foreign markets. Japanese government bonds previously had a 35 per cent weighting in total investments.

The changes are paying off, with the return last fiscal year on bonds and stocks combined beating the fund's composite benchmark for the first time in seven years.

Still, it is not possible to fully assess how well GPIF timed its adjustments because the fund does not disclose when during the 12-month period changes took place.

There was enormous movement in bonds over the period, with 10-year Treasury yields largely moving sideways over the first half of the fund's fiscal year before surging about 100 basis points to around 1.7 per cent in the second half.

The fund's smaller peers in Japan, which often follow its lead, will scrutinize the latest changes.

"GPIF has a large influence over the investment decisions of other pension funds in Japan," said market strategist Ayako Sera at Sumitomo Mitsui Trust Bank in Tokyo. "What it does has an impact in the market."

Looking at the more recent moves, Ms Sera sees the attractiveness of Treasuries dropping even further.

"Current yield levels don't compensate investors enough to take foreign-exchange risks," she said.

Treasury Department data show Japanese investors overall have sold a net US$24 billion of United States government bonds since the start of the Asian nation's current fiscal year on April 1. They offloaded US$35 billion in the 12 months before that, the most in three years.
