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#

Valuation Mark Age — 2026-09-04. Axes: bucket · instruments.

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.
