KBW Bank Index posts longest losing streak since the 2008 crisis
As seen on the 24/7 Wall St. homepage on October 17, 2026.
Six straight down weeks for bank stocks is a streak the market has not seen since 2008, and an 11% slide in that window says credit worries are no longer confined to one lender.
Large US bank stocks are under historic pressure: The KBW Bank Index has dropped for 6 consecutive weeks, its longest streak since the 2008 Financial Crisis. This also marks its 3rd-longest streak this century. Over this span, the index has fallen -11%, to its lowest level https://t.co/Wjb9fV8I7m

The KBW Bank Index has fallen for six consecutive weeks, matching a stretch last seen in the 2008 Financial Crisis and ranking as the third-longest losing streak for the index this century. The pressure on large US bank stocks is sector-wide.
The cumulative decline over those six weeks stands at 11%, pushing the index to its lowest level in the current period. Declines of that size in under two months reflect more than ordinary profit-taking.
Six weeks of sustained selling suggests the market is repricing the entire sector, whether on credit quality concerns, margin pressure, or broader macro anxiety. None of those resolve quickly.
A seventh consecutive down week would push this streak into territory with almost no modern precedent outside of 2008, intensifying scrutiny of individual bank earnings and loan-book health across the sector.
