Yen Plunges Amid Prospects of Eased Fiscal Measures; Dollar Gains Ground

The Japanese yen sharply declined to levels unseen since July 2024 in response to growing concerns about looser fiscal and monetary policy under Prime Minister Sanae Takaichi, who is reportedly considering an early general election. Meanwhile, the U.S. dollar broadly strengthened following inflation data aligned with economists' expectations, reflecting cautious optimism about easing price pressures.

Key Points

  • Japanese yen declined sharply due to expectations of looser fiscal and monetary policy under new Prime Minister.
  • U.S. dollar gained broadly after inflation data aligned with analyst forecasts, tempering rate cut expectations.
  • Possible Japanese government intervention and geopolitical issues are contributing to market uncertainty.

In the currency markets on Tuesday, the Japanese yen experienced a significant decline, falling to its weakest point against the U.S. dollar since July 2024. This depreciation reflects mounting apprehension regarding upcoming fiscal and monetary policy adjustments in Japan, where speculation is rising about further easing under the leadership of Prime Minister Sanae Takaichi.

Reports have surfaced that Prime Minister Takaichi is contemplating an early general election, potentially in February, a move confirmed indirectly by the leader of her coalition partner party. This election would enable her to leverage the considerable public support she has maintained since taking office in October.

Currency strategist Eric Theoret from Scotiabank in Toronto commented that such a development signifies a negative outlook for the yen. He noted that Takaichi is positioned as a dove concerning both fiscal and monetary policies, meaning she is likely to endorse looser fiscal spending and higher deficit tolerance, which traditionally weighs on the currency.

The yen retreated by 0.6% to 159.11 per U.S. dollar amid these developments. The pace of yen weakening has also heightened trader vigilance regarding the possibility of Japanese government intervention to support the currency. Finance Minister Satsuki Katayama expressed shared concerns with U.S. Treasury Secretary Scott Bessent about the yen's "one-sided depreciation," emphasizing Tokyo's intensified stance on staving off further declines through potential market intervention.

On the other side of the Pacific, the U.S. dollar demonstrated broad strength, rebounding after a brief retracement prompted by inflation data that largely matched economist forecasts. The December Consumer Price Index showed a 0.3% monthly increase, translating to an annual rise of 2.7%. Meanwhile, core CPI, which excludes volatile food and energy prices, grew by 0.2% for the month, marking a 2.6% increase year on year.

Preston Caldwell, Morningstar’s chief U.S. economist, remarked that the data reinforced the notion of declining inflation trends. The market had been cautiously anticipating potentially higher inflation figures, so the outcomes bolstered a view that inflation might have reached a relative low point. This sentiment supported gains in more risk-sensitive currencies such as the Australian dollar, which initially rallied following the CPI release.

Nonetheless, Federal Reserve officials continue to deliberate on the extent to which productivity improvements will facilitate a return to the central bank's 2% inflation target. They have reiterated the necessity to maintain current interest rate levels until inflationary pressures clearly ease.

Correspondingly, the dollar index, measuring the greenback against a range of major currencies including the euro and yen, rose by 0.28% to 99.15. Among other currencies, the euro declined 0.17% to $1.1647, and the British pound slipped 0.23% to $1.3428. The Australian dollar faced a slight decrease of 0.45%, settling at $0.668 after a temporary uptick to $0.6725 prompted by the inflation figures.

The U.S. dollar’s recent strength also builds on last Friday’s data revealing robust December job growth. This reinforced market expectations that the Federal Reserve will maintain interest rate levels at its January 27-28 meeting. Futures traders indicate that a rate cut is unlikely before June.

Market participants are also monitoring developments around the Federal Reserve’s independence after the U.S. Department of Justice reportedly threatened an indictment against Fed Chair Jerome Powell related to a building renovation project. In response, global central bank leaders issued a joint statement expressing support for Powell. Meanwhile, former President Donald Trump is anticipated to announce his candidate to succeed Powell when his term ends in May, asserting that the recent inflation data favors his push for rate reductions.

Additional geopolitical concerns persist, including the United States detaining Venezuelan leader Nicolas Maduro, ongoing protests in Iran, and Trump's expressed interest in acquiring Greenland. Traders are also awaiting a Supreme Court decision on the legality of Trump-era tariff policies, expected imminently.
