BAMLC0A0CM — ICE BofA US Corporate Index Option-Adjusted Spread (Investment Grade). It tracks investment-grade-rated US corporate bonds and is published on the same daily, business-days-only cadence as the site's tracked hy-spread (BAMLH0A0HYM2), with roughly a one-business-day lag. Read alone it only says whether IG borrowing costs are cheap or expensive. Charted against hy-spread, the gap between the two is the real signal: it shows whether credit stress is confined to junk-rated borrowers or has spread up into investment grade.
