TOKYO - Japan's government is readying to unfetter its huge public pension fund, freeing managers to dump low-yield sovereign bonds and go in search of higher, but riskier returns, in a move that could see cash flood global markets.
The nation's pension programme, into which almost all citizens pay, is supported by the world's largest investment fund, worth a staggering $1.26 trillion - equivalent to one-quarter of the country's entire economy.
It towers over its nearest competitor - the $700 billion belonging to Norway - and is multiples of the $173 billion holdings of Temasek, the Singaporean sovereign wealth fund.
But, unlike some other more adventurous vehicles, the Government Pension Investment Fund (GPIF) keeps by far the majority of its cash in super-safe - and super low return - Japanese government bonds.
Now all that could be about to change, as Prime Minister Shinzo Abe shuffles into place the next piece of his "Abenomics" jigsaw puzzle.
The bid to shake up Japan's slumbering economy after two decades of drift began in early 2013 with a huge public spending bonanza and unprecedented monetary easing from the Bank of Japan.
But, 18 months down the line, the initial sugar rush is fading, and Abe must now put in place some of the structural reforms he - and most economists - say are necessary.
Not least of which is getting more bang for the buck on the public pension fund to help a shrinking number of workers pay for a growing number of retirees.
About half of Japan's social security budget goes on pensions, a figure equal to around 12 per cent of the entire economy. Bolstering the performance of the reserve fund would take pressure off the public purse.
One trillion yen
Earlier this month, Abe reportedly instructed his welfare minister to review the fund's operating portfolio, urging it to make more aggressive investments in foreign and domestic stock markets.
The knock-on effect, say analysts, could be huge.
"Moving just one per cent of the fund onto stock markets - there goes more than one trillion yen ($9.8 billion) right there," said Tsuyoshi Ueno, a senior economist at NLI Research Institute.
