USD/JPY at 162.75 pushes well past the levels that triggered Japan's last intervention, keeping MoF action risk elevated into a period traders see as tactically favourable given Friday's thinner US holiday liquidity. The bigger driver remains the US side of the pair, with Treasury yields jumping overnight and Fed hike odds for September surging to 67% from just 20.5% a month ago, a repricing that has more room to run into Thursday's payrolls data. A resilient labour market read, even with softer hiring, is reinforcing the hawkish case and narrowing the runway for anyone still expecting the Fed to hold. Warsh's Wednesday appearance at the ECB's Sintra forum is a watch item, though expectations for fresh guidance are low given his reluctance to signal forward direction last month.---The yen hit a 40-year low near 162.75+ per dollar as US Treasury yields jumped and traders lifted Fed September hike bets to 67% from 20.5% a month ago.Earlier:MUFG: Japan's FX warnings fall short of signalling imminent yen interventionSummary:The yen fell to its lowest level since 1986 on Wednesday, with the dollar rising to around 162.75 in early Asian trading, above the levels that prompted Japanese intervention a few months agoTraders are watching Friday's US public holiday as a potential window for Tokyo to intervene, given thinner liquidity could amplify the impact of any actionThe dollar's advance followed an overnight jump in Treasury yields, with the 10-year yield rising as much as 9 basis points intraday before closing 4.8 basis points higherThe 2-year Treasury yield rose 3 basis points to 4.1702%US job openings edged up to a two-year high in May, though weaker hiring dented consumer perceptions of the labour marketTraders are now pricing a 67% chance of a Fed rate hike in September, up sharply from 20.5% a month ago, according to the CME FedWatch toolFocus turns to Fed Chair Kevin Warsh's appearance at the ECB Forum on Central Banking in Sintra, Portugal on WednesdayThe yen slid to its weakest level since 1986 on Wednesday, with the dollar pushing to a fresh peak near 162.75 in early Asian trading, comfortably above the levels that prompted Japanese authorities to intervene in support of the currency a few months ago. The move has left traders on alert for renewed action from Tokyo, with attention turning to Friday's US public holiday as a potential window for intervention, given that thinner liquidity conditions around the holiday could magnify the impact of any yen-buying operation.The dollar's broader strength was underpinned by a sharp overnight rise in US Treasury yields. The 10-year yield climbed as much as 9 basis points intraday on Tuesday before settling around 4.8 basis points higher on the session, while the 2-year yield added 3 basis points to close at 4.1702%. There was no single clear catalyst behind the move, with some of the pressure potentially tied to month-end positioning flows rather than any fresh data or policy signal.The yield jump came ahead of Thursday's closely watched US non-farm payrolls report. Data released overnight showed US job openings rose to a two-year high in May, even as softer hiring activity weighed on consumers' perceptions of the labour market. That resilience in the labour market has been read as reinforcing the case for the Federal Reserve to stay on a hawkish footing, with little in current conditions supporting an argument for rate cuts under the Fed's dual mandate. Traders are now pricing a 67% probability of a Fed rate hike in September, a sharp jump from just 20.5% a month earlier, according to the CME FedWatch tool, as inflation running above target and better than expected US data narrow the case for holding policy steady.Markets are also looking ahead to Federal Reserve Chair Kevin Warsh's appearance at the European Central Bank's Forum on Central Banking in Sintra, Portugal, on Wednesday. Expectations for fresh policy signals from that appearance remain limited, given Warsh's reluctance to offer forward guidance in his most recent public remarks.---US markets are closed on Friday, which may provide Japan's Ministry of Finance an opportunity to get more 'bang for its buck' in intervention: This article was written by Eamonn Sheridan at investinglive.com.
