Shares of major United States banks are on course for their longest run of weekly declines since the 2008 financial crisis, as investors weigh a mixed set of quarterly earnings results against renewed pressure from rising inflation.

The KBW Bank Index, a widely followed benchmark of large US lenders compiled by investment bank Keefe, Bruyette & Woods, has fallen about 13% since peaking in August. The index's current streak of weekly losses has reached a length not seen since 2008, when the collapse and rescue of major financial institutions triggered a global financial crisis. The comparison refers to the duration of the streak — consecutive weeks of closing declines — rather than a replay of that era's conditions, though benchmarks measured against 2008 tend to draw close scrutiny because that year remains the reference point for systemic stress in the banking sector.

Beyond earnings and inflation, concerns that artificial intelligence could disrupt financial services have added to the negative sentiment surrounding bank stocks, as market participants assess how the technology might reshape parts of the industry.

Analysts also highlight challenges stemming from elevated interest rates, which could slow economic growth and add further pressure on the sector. With quarterly results still being weighed, further earnings updates and inflation readings remain the immediate focal points for investors tracking the group.
