The Bank of Japan’s failure to spur demand for its cheap loans is forcing it to buy more treasury bills rather than make more productive asset purchases.

The BOJ has raised holdings of bills maturing in one year or less by ¥7.21 trillion this year as of Feb. 28, exceeding the ¥6.09 trillion increase for the eight months through Dec. 31 after the central bank radically expanded stimulus in April.

In contrast, the outstanding balance of its loan programs fell 10 percent between April and February. Three-month bill rates have almost halved in the past six months to 0.04 percent, while those in the United States have risen three basis points.

Gov. Haruhiko Kuroda has succeeded in increasing the supply of money by buying bills and bonds, weakening the yen and putting Japan on the path toward its 2 percent inflation target. He has been less successful in encouraging banks to boost lending and finding takers for the BOJ’s favorable 0.1 percent loans, reflecting the limitations of relying on monetary policy to spur economic growth.

“I can’t rule out the possibility that bill yields will briefly break below zero,” said Toshiaki Terada, a researcher at Totan Research Co., a money-market brokerage in Tokyo. “There’s little benefit for financial companies in borrowing at 0.1 percent because there aren’t any worthy assets available that offer higher returns.”

A negative rate means investors who hold the debt until expiry will receive less than they paid to buy. U.S. three-month bill yields fell to negative 0.0101 percent on Sept. 27 amid political gridlock over the budget. Germany sold two-year notes in July 2012 with a yield below zero for the first time ever as a sovereign-debt crisis prompted investors to seek safety.

Japan’s ¥3.2 trillion sale of six-month treasury discount bills on March 5 drew an average yield of 0.0337 percent, the lowest on record dating back to 2007. The offering of three-month securities the next day saw the yield fall to 0.0328 percent, the second least in data starting July 2012.

The BOJ bought ¥2 trillion of bills on Feb. 28 with yields 0.2 basis point lower on average than market rates. Three-month securities yielded 0.036 percent that day, data compiled by the Japan Securities Dealers Association showed.

The “tight” supply-demand balance for T-bills will keep their yields anchored, prompting investors to buy longer-maturity government bonds for higher returns, according to Tomohiro Miyasaka, the Tokyo-based director for fixed-income strategy at Credit Suisse Group AG, one of the 23 primary dealers obliged to bid at government debt auctions.

The extra yield that investors can get by holding two-year sovereign notes instead of three-month bills has shrunk to three basis points. The comparable spread is 32 basis points in the United States and eight basis points in Germany.

The benchmark 10-year note yield fell to as low as 0.57 percent on March 3, a level unseen since May 7. While yields will remain at the current levels for the rest of this year, bill rates are unlikely to fall below zero, Credit Suisse’s Miyasaka said.

“If interest on bank deposits for savers becomes negative, money-market funds would not be able to secure the principal,” he said. “Considering such a broad impact, it’s technically very difficult” for bill rates to be negative.

In addition to purchasing bills and offering 0.1 percent loans to banks, the BOJ buys about ¥7 trillion of government debt every month to spur lending and investments in riskier assets through lower borrowing costs. Demand for bank lending is still muted as businesses are awash with cash.

The outstanding balance of domestic bank loans was at ¥413 trillion in January, 23 percent lower than a record high in 1996, though it increased 2.5 percent from a year earlier. Nonfinancial private companies in Japan held a record ¥224 trillion in cash at the end of September, the latest BOJ data show, which is bigger than Russia’s gross domestic product in dollar terms.

The BOJ, which was to conclude a two-day board meeting Tuesday, will keep its main policy target of expanding the monetary base at a pace of ¥60 trillion to ¥70 trillion per year, according to 33 of 34 economists surveyed by Bloomberg. Meiji Yasuda Life Insurance Co. forecasts the BOJ will boost the target to ¥80 trillion to ¥90 trillion.
