Country Rates Board (UK / EA / JP)

Comparing curves across countries usually means comparing conventions. This operator puts UK, euro-area and Japanese rates on ONE taxonomy — the same 7-class 2s10s regime read used for the US — plus each country's policy rate, 10Y decomposition where official legs exist, and for the UK the OIS-implied path in 25bp moves. Its defining feature is that coverage honesty is part of the output: every leg a country lacks is declared with its reason, so a board never silently looks more complete than its sources are. At ship time the boards read: UK bear_flattener with ONE 25bp hike priced (gilt 10Y above 5%), EA bear_flattener at a 2.25% deposit rate, and Japan twist_flattener with the steepest 2s10s of the three.
