Wednesday's minutes from the Fed's July meeting (0.25% hike) had a hawkish tilt and kept the door open to more hikes, showing that "most participants" still see upside risk to inflation, which "could require further tightening" of the monetary policy . Coupled with strong retail sales, industrial production and overall resilient economy, they helped USD/JPY to new 2023 highs.
It pulls back from those highs though, as it also moved into the levels (dashed line) that had prompted Japanese authorities to steep in the FX market in support of the Yen, nearly a year ago. This crates some caution for new intervention, verbal or actual.
Today's CPI report from the country sustains the pressure, since core-core inflation ticked back up to 4.3% y/y, matching the May reading and the highest since 1981. CPI ex-fresh food eased to 3.1% y/y, but stayed above the 2% target for eleventh straight month.
The Bank of Japan raised its FY2023 forecast for CPI ex-fresh food, to a median of 2.5% (from 1.8% previously) , but still thinks there is more work needed. Policymakers believe that "sustainable and stable achievement" of the 2% target "has not yet come in sight". 
Today's inflation figures do keep pressure for an exit from the ultra-loose policy setting that has been detrimental to the Yen, but they are not strong enough to compel the BoJ to change its ways. Officials did take another step towards policy normalization in July, since they essentially loosened the yield curve control, but this maneuver also allows them to maintain their dovish stance for longer.
USD/JPY slides further today as it hovers around intervention levels and markets still look for policy normalization by the BoJ. This creates scope for a correction towards the EMA200 (142.70-80), but the downside is well protected and daily closes below it have a high degree of difficulty.
Bulls are in control though, and have the ability to challenge 148.83. The hawkish Fed minutes keep more tightening in play and markets adjust to prospects for prolonged restrictive stance, while the policy differential continues to favor the greenback.
