[MARKET ANALYSIS] Fixed contained on the UK Bank Holiday, USTs briefly take out last week's low, Bunds await mainland inflation

• A contained start to the week for fixed income. The European morning has been particularly quiet, owing to the fact that the UK is away on Bank Holiday. USTs are currently firmer by a few ticks, in 108-01 to 108-09 parameters; note, the initial low went below last week’s trough by half a tick, and any resumption of the move looks to 107-31+ from the last week of July.
• Overnight, USTs, JGBs and Bunds were all in relatively narrow ranges and ultimately didn't significantly differ from the unchanged mark. Broadly speaking, the main focus was the weekend’s geopolitical updates and particularly US action on Larak Island and then Iranian retaliation.
• Geopolitics aside, desks remain focused on the speech by Fed Chair Warsh last week, which had a hawkish skew and has contributed to the implied probability of a September 25bps hike increasing to just under 60% currently via CME, vs around 41% one week ago.
• Bunds reside in the red by a few ticks. Nonetheless, the benchmark holds at the upper-end of 123.43-60 parameters. No move to the German State CPIs, which saw the Y/Y tick up modestly from the prior, in-fitting with consensus for the 13:00BST mainland figure. On Tuesday, we get the Flash EZ HICP series, and given what we have seen so far the energy component may be the most pertinent.

Holiday-thinned sessions of this kind have a well-established pattern: ranges compress, technical levels carry more weight than they would on a full desk, and breaks of prior lows on half a tick of follow-through are read as indicative rather than conclusive until normal liquidity returns. The distinction worth drawing is between the technical picture in USTs, where a marginal takeout of the prior week's trough leaves the next support zone as the operative reference, and the macro driver, which here is repricing of the rate path off hawkish communication from the Fed chair rather than fresh data. In past episodes where implied probabilities of a near-term policy move have shifted this quickly on rhetoric alone, the move has tended to hold only if subsequent data and follow-up commentary from other officials corroborate it; the risk of partial retracement on pushback or a soft print is the established sequence. For Bunds, the state-level CPI prints feeding into the national and then the flash euro-area HICP are the standard relay, with the energy component the usual swing factor in the aggregate. The calendar is the tell: whether mainland inflation confirms the state-level uptick determines whether the bearish skew in Bunds extends, and the return of UK participation typically restores the two-way flow that holiday sessions lack.
