The second auction of the 30-year bond first issued a month ago is due at the top of the hour. The when-issued market is pricing the bond at 3.340% tend of affect USD/JPY less than the 2 or 5-year space. A yield at 3.36% or higher might drive a ‘risk on’ trade that would benefit commodities and risk FX. A yield around 3.34% triggers the opposite, but probably to a lesser extent. People used to get geared up for 30-year sales when they only came once per quarter, those were the good old days.
