Corporate Bonds#

These records are retained because their stated maturity has not passed, but their ISIN is absent from the current BIST instrument master. Same-day timing and instruments outside the listed master are both possible; the dashboard does not silently treat them as listed bonds.

Today's Trades with Treasury Spread#

Same-day corporate yield less the interpolated TRY nominal treasury yield, in basis points.

Coverage today: 59 distinct corporate ISINs traded · 9 had a published yield · 2 mapped to the treasury curve range. BIST publishes a compound return only on a subset of corporate trades — yieldless rows are price-only and would require bond-math to spread.

Each dot = one bond's spread. With 2 bonds priced today, a histogram would be misleading; strip plot shows actual values cleanly.

Recent Auctions — Primary Spread to Treasury#

382 corporate primary issuances where the auction date falls inside our backfilled treasury history. Auction yield is converted to compound when tbliste publishes a simple annual value; treasury yield is interpolated on the auction date. Sorted newest first — this is your primary market activity feed.

Historical Spread Snapshot — 59 Corporate ISINs#

Each row = one corporate ISIN's most recent observed yield, compared to the TRY treasury yield interpolated on the same day at that observation's DTM. Sorted widest spread first. This pools across the full backfilled history so the table doesn't depend on what traded today.
