Stale Valuation Marks#
BIST publishes an official settlement price for every listed
instrument in tfd daily. For non-trading bonds, that price is the
last actual trade — so the mark "ages" until the next trade. This page tracks
that aging.

Mark Age Distribution#
Why is 31-90d so large? Bonds in that window were actively quoted but haven't printed yet — dealers are showing axes but no transactions have crossed. Watch this bucket: when one of these prints, it can move that issuer's mark several pp at once.
Mark-Snap Risk — TRY Bonds Stale 30-180 Days, Still Active#
These are TRY-denominated bonds whose valuation hasn't refreshed in over a month but which haven't matured. When one of these prints next, the mark can jump several pp — relevant for any MTM portfolio holding them.
