Japan's central bank decided Tuesday to end its negative interest rate policy and introduce a rate hike for the first time in 17 years, marking a historic step away from its unprecedented monetary easing framework of the past decade that was intended to end deflation.

Despite the highly anticipated landmark hike, the Bank of Japan (BOJ) still keeps rates stuck around zero. A fragile economic recovery forces the central bank to slow any further rise in borrowing costs, analysts say.

The shift made Japan the last central bank to exit negative rates and ended an era in which policymakers around the world sought to prop up growth through cheap money and unconventional monetary tools.

"We reverted to a normal monetary policy targeting short-term interest rates, as with other central banks," BOJ Governor Kazuo Ueda said at a news conference after the decision. "We will choose the appropriate level of short-term rates in line with our economic and price outlook."

"The BOJ today took its first, tentative step towards policy normalization," said Frederic Neumann, chief Asia economist at HSBC in Hong Kong.

"The elimination of negative interest rates in particular signals the BOJ's confidence that Japan has emerged from the grip of deflation."

In a widely expected decision, the BOJ ditched a 2016 policy that applied a 0.1% charge on some excess reserves financial institutions parked with the central bank.

The BOJ set the overnight call rate as its new policy rate and decided to guide it in a range of 0-0.1% partly by paying 0.1% interest to deposits at the central bank.

The central bank also abandoned yield curve control (YCC), a policy that had been in place since 2016 that capped long-term interest rates around zero.

However, in a statement announcing the decision, the BOJ said it will keep buying "broadly the same amount" of government bonds as before and ramp up purchases in case yields rise rapidly.

The BOJ additionally decided to discontinue purchases of risky assets like exchange-traded funds (ETF) and Japanese real estate investment trusts.

"We judged that sustainable, stable achievement of our price target came in sight," the central bank said in a statement explaining the decision to dismantle former Governor Haruhiko Kuroda's massive stimulus program.

With inflation having exceeded the BOJ's 2% target for well over a year, many market players had projected an end to negative interest rates either in March or April.

Expectations for a shift this week heightened significantly after unions' annual wage talks with major firms delivered the biggest pay hikes in 33 years.

As a sign that any future rate hike will be moderate, the BOJ said in its statement that it expects "accommodative financial conditions will be maintained for the time being."

The language compared with the more dovish guidance that was removed from the statement, in which the BOJ pledged to ramp up stimulus as needed and keep increasing the pace of money printing until inflation stably exceeded 2%.

Japanese shares were volatile on Tuesday. The yen fell to almost 150 per dollar, as investors took the BOJ's dovish guidance as a sign that the interest rate differential between Japan and the United States would likely not narrow much.

The stakes are high. A spike in bond yields would boost the cost of funding Japan's huge public debt, which, at twice the size of its economy, is the largest among advanced economies.

An end to the world's last remaining provider of cheap funds could also jolt global financial markets as Japanese investors, who amassed overseas investments in search of yields, shift money back to their home country.

Under previous Governor Kuroda, the BOJ deployed a massive asset-buying program in 2013, originally aimed at boosting inflation to a 2% target within roughly two years.

The central bank introduced negative rates and YCC in 2016 as tepid inflation forced it to tweak its stimulus program to a more sustainable one.

As the yen's sharp falls pushed up the cost of imports and heightened public criticism over the demerits of Japan's ultra-low interest rates, however, the BOJ last year tweaked YCC to relax its grip on long-term rates.
