IMF sees Japan's currency intervention as 'signaling' move with short-term impact

  • IMF official: Not the time for BOJ yield control tweaking
  • Japan's intervention likely tied to yen's impact on capex
  • Intervention was one-time event of relatively small size
  • Impact of intervention doesn't last long, IMF says

WASHINGTON, Oct 13 (Reuters) - Japan's currency intervention last month to stop a sharp slide in the yen was likely a "signaling action" to smooth volatility, though the impact of such moves tend to be short-lived, a senior International Monetary Fund official said on Thursday.

Recent volatile market moves heighten the need for the Bank of Japan to maintain ultra-low interest rates and avoid making tweaks to yield curve control (YCC), Sanjaya Panth, deputy director for the IMF's Asia and Pacific Department, told Reuters in an interview.

"We think this is not a good time to change YCC. In a particularly volatile situation where markets are edgy and many things are happening, you want to offer continued commitment to monetary easing until inflation picks up durably," Panth said.

"It's a very important signal the BOJ needs to provide. Tinkering with that right now may confuse markets. We don't see room for that," he said.

Some investors speculate the BOJ could tweak YCC and allow Japanese yields to rise more to moderate the pace of yen falls.

Japan spent roughly 2.8 trillion yen ($19 billion) intervening in the currency market last month to arrest sharp drops in the value of the yen, which were driven largely by the policy divergence between the U.S. central bank's aggressive interest rate hikes and the BOJ's resolve to keep monetary policy ultra-loose.

Markets are focusing on whether Japan will step in again, as stronger-than-expected U.S. inflation data pushed the dollar to a fresh 32-year high against the yen of 147.665.

Speaking in Washington, Japanese Finance Minister Shunichi Suzuki said on Thursday authorities were ready to take "appropriate action" against excessive volatility.

Panth said Japanese authorities likely intervened last month with the view that the yen's "pretty sharp" moves could dampen corporate investment and hurt consumer confidence.

Although interest rate increases by the U.S. Federal Reserve and the European Central Bank remain key drivers of currency moves, authorities most likely saw the yen's recent "particularly sharp moves" as driven by no new information of relevance, he said.

"It was a fairly small amount given how liquid the market is," Panth said, referring to the size of Japan's intervention. "It seems more of a signaling action to smooth the market's adjustment."

"When there is intervention, it does slow down the pace of depreciation. We saw that in this round in September. When looked at historically, the impact of these kinds of interventions doesn't last very long," he said.

Once welcomed as giving exports a boost, the weak yen has become a headache for Japanese policymakers by inflating the cost of importing already expensive fuel and food.

"What is of relevance is the overall stance of monetary and fiscal policy, which remains appropriate. The intervention was a one-time event so far of relatively small magnitude in a deep market."
