It last traded at \u2060159.09 to the dollar after trading as low 163.65 on Thursday.<\/p>\n<p>The method of potential Treasury intervention was not immediately clear. The Federal Reserve has \u200bmaintained a dollar liquidity swap line with the Bank of Japan and four other major central banks since 2013.<\/p>\n<p>Japan&#8217;s top currency diplomat \u200bAtsushi Mimura in Tokyo Friday declined to comment on intervention but hinted at U.S. involvement in the effort to stem the yen&#8217;s decline, including so-called &#8220;rate checks&#8221; &#8212; requests to dealers for indicative dollar\/yen quotes that are considered a precursor to interventions.<\/p>\n<p>Mimura added that the U.S. support &#8220;goes beyond psychological support.&#8221;<\/p>\n<p>The Reuters report of Treasury&#8217;s \u200bnotice to banks of potential intervention &#8220;fits in with the view in the market that the New York Fed has been carrying rate checks, \u200bso it&#8217;s adding to the nervousness of market participants that there could be further intervention,&#8221; said Lee Hardman, currency strategist at MUFG in London. &#8220;It definitely helps \u200csupport the \u2060idea that there is intervention risk on the table.&#8221;<\/p>\n<p>U.S. Treasury Secretary Bessent said in an X social media post that the Treasury maintains &#8220;a strong relationship and close coordination&#8221; with Japanese authorities, but did not confirm the intervention preparations.<\/p>\n<p>He said he looked forward to meeting with Bank of Japan Governor Kazuo Ueda at the U.S.-hosted G20 finance ministers and central bank governors meeting in Asheville, North Carolina, at the end \u200bof August.<\/p>\n<p>&#8220;Japan&#8217;s economy continues to perform \u200bwell under Prime Minister Takaichi, \u2060Governor Ueda and the Bank of Japan Board, which has demonstrated a strong commitment to monetary and financial stability,&#8221;<\/p>\n<p>On Thursday, U.S. Treasury Secretary Scott Bessent told Fox Business Network that the yen &#8220;seems very undervalued to \u200bme&#8221; and that Japanese Prime Minister Sanae Takaichi was enacting &#8220;strong policies&#8221; that would help Japan&#8217;s economic fundamentals.<\/p>\n<p>Bessent \u200badded that &#8220;we think excess \u2060volatility in the yen isn&#8217;t healthy&#8221; and that the yen has &#8220;substantially overshot what would be called an equilibrium price.&#8221;<\/p>\n<p>The last time that the U.S. Treasury intervened directly to prop up Japan&#8217;s yen was in 2011 as part of a coordinated action by G7 countries to stabilize the currency after a devastating \u2060earthquake and \u200btsunami rocked Japan.<\/p>\n<p>The Treasury last fall intervened to prop up Argentina&#8217;s peso market \u200bahead of parliamentary elections and provided President Javier Milei&#8217;s government with a <a data-testid=\"Link\" referrerpolicy=\"no-referrer-when-downgrade\" href=\"https:\/\/www.reuters.com\/world\/americas\/us-purchased-argentine-pesos-after-top-finance-officials-meeting-bessent-says-2025-10-09\/\" class=\"text-module__text__0GDob text-module__inherit-color__PhuPF text-module__inherit-font__1P1hv text-module__inherit-size__EyiQW link-module__link__INqxZ link-module__underline_default__-okuC\" rel=\"nofollow noopener\" target=\"_blank\">$20 billion currency swap line<\/a> to help stabilize the currency and Argentina&#8217;s dollar bonds.<\/p>\n<p>The aid to Argentina relied \u200bpartly on the Exchange Stabilization Fund, which had total assets of about $217 billion as of June 30.<\/p>\n<p data-testid=\"SignOff\" class=\"text-module__text__0GDob text-module__dark-grey__UFC18 text-module__regular__qJJtA text-module__extra_small__8Buss body-module__full_width__kCIGb body-module__extra_small_body__Bfz20 sign-off-module__text__LQAMP\">Reporting by David Lawder;
