Japan Intervenes to Support Yen for the First Time Since 1998

·4 min read

(Bloomberg) -- Japan intervened to prop up the yen for the first time since 1998, after its central bank sparked further declines in the currency by sticking with ultra-low interest rates as its global peers hiked.

The yen rose as much as 2.5% against the dollar, pulling back sharply from the lows of the day when it had breached a key psychological level of 145, as top currency official Masato Kanda said Thursday the government was taking “decisive action.”

The intervention shows that Prime Minister Fumio Kishida’s government has reached the limit of its patience after the yen tumbled around 20% against the dollar this year as hedge funds kept adding to short bets on the yen. The question now is whether the unilateral action will work, with the currency deeply volatile in trading after the comments.

“I think they went in solo, but they can’t do so without at least informing the US,” said Nobuyasu Atago, chief economist at Ichiyoshi Securities and a former BOJ official. “If they really want to change the yen’s slide as a trend, I think the government needs to get its act together with the BOJ.”

The currency extended gains in New York trading hours, touching an intraday high of 140.36 per dollar. Earlier, it had weakened to 145.90 as the Bank of Japan stuck to holding rates down even as the Federal Reserve hiked for the fifth time this year.

“The government is concerned about excessive moves in the foreign exchange markets, and we took decisive action just now,” Kanda said late afternoon. “We’re seeing speculative moves behind the current sudden and one-sided moves in the foreign exchange market.”

In remarks in New York later, Kishida said they will take necessary action if there’s an excessive move in the currency. He reiterated the government is seeing speculative moves recently and added it’s important for the exchange rate to be stable.

The US Treasury said it understood Japan’s action to intervene in the foreign-exchange market Thursday, noting Japan’s statement that it was aimed at reducing recent heightened volatility of the yen. The US didn’t participate in the intervention, according to the statement, which did little to budge markets.

The intervention, ordered up by the Ministry of Finance, comes with risks if it fails to scare off speculators. Hedge funds have been adding to bearish bets on the currency, with Goldman Sachs Group Inc. warning it may decline all the way to 155.

“At best, their action can help to slow the pace of yen depreciation,” said Christopher Wong, a currency strategist at Oversea-Chinese Banking Corp. “The move alone is not likely to alter the underlying trend unless the dollar, US Treasury yields turn lower or the BOJ tweaks its monetary policy.”

BOJ Governor Haruhiko Kuroda insisted at a briefing in the Tokyo afternoon there were no rate hikes in the works and guidance on future policy would not be change for the time being, even for as long as two or three years in principle. Still, his influence over policy will fade next April when he steps down.

“Today’s outcome strengthens my view that the chance of policy change is almost zero under Kuroda’s governorship,” said Masamichi Adachi, chief Japan economist at UBS Securities.

Kuroda’s stance sets him apart from other central banks that had also previously had negative rates, with the European Central Bank and the Swiss National Bank all hiking to deal with surging inflation.

What Bloomberg Economics Says....

“The MOF cannot sustainably move the market on its own. Still, Thursday’s move was needed as Japan heads into a long weekend starting Friday and after inaction from the Bank of Japan and comments from Governor Haruhiko Kuroda invited speculative bets against the battered currency.”

The combination of central bank easing and government intervention suggests a division of labor to support the country’s policy stance.

“For the time being, we could see some unwinding of yen shorts, particularly if the BOJ continues to intervene in the market on the behalf of the finance ministry over early next week,” said Jian Hui Tan, strategist at Informa Global Markets. “What it probably does is buy Japan some time, in the hope that broad USD strength moderates somewhat and any further yen depreciation can be slowed.”
