The US dollar's renewed strength has once again pushed the Japanese yen past the 160 mark, sparking speculation about potential intervention. In response, US Treasury Secretary Scott Bessent has stepped forward to set the tone.

The yen slipped to 160.11 on Monday, triggering widespread market speculation about a possible coordinated intervention by the US and Japan. In a Sunday interview with Reuters, Bessent stated that recent yen movements have been "reasonably well contained," a stark contrast to the "disorderly" conditions that prompted previous intervention. He also expressed confidence that Bank of Japan Governor Kazuo Ueda will "do the right thing" on monetary policy, and revealed plans to meet with him during this week's G20 Finance Ministers and Central Bank Governors meetings.

While Bessent's comments somewhat tempered expectations of immediate intervention, he also delivered a deeper policy signal—explicitly stating that Japan's era of "Abenomics" has reached its endpoint, and that the Japanese economy is transitioning to a new phase characterized by a more market-oriented approach.

Yen Breaches 160 Again, Bessent Says Currency 'Under Control'

The yen has once again fallen below the 160 level, widely viewed by markets as the intervention warning line. The immediate catalyst for this depreciation was a hawkish speech by Federal Reserve Chairman Kevin Warsh, who signaled a firm commitment to achieving the inflation target, which boosted the dollar.

The 160 level carries significant psychological weight for the market. Just last month, the US and Japan implemented a rare coordinated yen-buying intervention to prevent the selloff in the yen and Japanese government bonds from spreading to global markets. With the yen again approaching and breaching this level, market attention has naturally focused on whether authorities will step in once more.

However, analysts point out that the root cause of this yen weakness lies in dollar strength and expectations of higher US interest rates, rather than domestic Japanese factors, which may lead authorities to adopt a wait-and-see approach regarding intervention.

Addressing market speculation about intervention, Bessent made his position clear in the Reuters interview, stating that the current yen movements are "reasonably well contained," differing from the "disorderly" situation that triggered last month's joint intervention. This statement signals to the market that the US and Japan do not currently view the yen's depreciation as requiring immediate action.

Bessent: Japan's Central Bank 'Will Do the Right Thing'

Bessent also revealed plans for a bilateral meeting with Ueda during the two-day G20 Finance Ministers and Central Bank Governors meeting, which began Monday in Asheville, North Carolina.

Bessent spoke highly of Ueda, saying, "I've known him for 15 years. He's an excellent economist, and the market underestimates his acumen."

Notably, Bessent has previously made repeated public calls for the Bank of Japan to raise interest rates to combat inflation and yen depreciation. These statements have already pushed the market to almost fully price in a rate hike at the September policy meeting.

Ahead of the G20 meetings, Bessent also publicly defended last month's joint intervention. It was reported that he responded to a letter from Democratic Senator Elizabeth Warren, explaining the rationale for US participation in the yen intervention.

In his letter, Bessent argued that a disorderly yen depreciation could force Japan to passively sell US Treasuries, ultimately pushing up borrowing costs for American households and businesses. This statement clearly articulates the interest logic behind US participation in the intervention—maintaining yen stability is, in essence, maintaining the stability of the US Treasury market.

The End of 'Abenomics' and the Dawn of 'Takaichi-nomics'

Another significant signal from Bessent's interview was his qualitative assessment of Japan's economic policy framework. He stated that Japan has "conquered" deflation and that "Abenomics"—the reflationary policy framework centered on massive monetary stimulus, fiscal expansion, and growth reforms—has reached its historical endpoint.

"I think we are probably at the end of Abenomics, which was a reflation program," Bessent said.

He noted that Japan, under Prime Minister Takaichi Sanae, is transitioning to "Takaichi-nomics"—a new framework that is more shareholder-friendly, with significant deregulation particularly in the labor sector and less government intervention.

Bessent's advice on Japan's fiscal policy was succinct: "I think they should sit back and enjoy the fruits of Abenomics, and let it run."

On monetary policy, while Bessent declined to directly instruct the Bank of Japan to hike rates aggressively, his words conveyed trust and expectation in Ueda: "I'm not going to tell them what to do, but I do think Governor Ueda will do the right thing with the support of Prime Minister Takaichi."
