Columbia Financial, Washington Trust Bancorp, and Old Second Bancorp Shares Skyrocket, What You Need To Know
Shares of Columbia Financial (CLBK), Washington Trust Bancorp (WASH), and Old Second Bancorp (OSBC) rose after June inflation data showed CPI at 3.5% and softer producer prices, cooling expectations for further Fed hikes. The article links the move to improved sentiment for regional banks and notes CLBK’s prior $597 million Northfield Bancorp deal and 48.9% YTD gain.
How this was made

The 30-second read
Why it matters
It frames the move as a rates-driven sentiment shift for regional banks, with KRE trading near 2026 highs. For each named bank, the text emphasizes the stock’s intraday jump but does not introduce new company-specific disclosures in the current session.
Market read
Traders get a rates-to-regional-banks read-through and a snapshot of which names moved, but no fresh CLBK/WASH/OSBC-specific catalyst is disclosed beyond the macro setup.
What to watch
Regional banks can still face credit-cycle risk and deposit betas that do not fully normalize quickly; the article provides no bank-specific credit or deposit metrics for CLBK, WASH, or OSBC today.
Background
The article is a multi-stock market wrap linking a regional-bank rally to softer inflation prints and a wave of large-bank earnings that supposedly stabilize net interest income and credit-loss expectations.
Ticker impact
Columbia Financial shares jumped 4.1% in the afternoon session, framed as read-through from cooling inflation and regional-bank sentiment.
Likely supports continued upside bias intraday to the extent rate-hike expectations keep easing.
The move is attributed to softer inflation and sector earnings read-through, while the only CLBK-specific deal mentioned (Northfield Bancorp acquisition) is described as occurring 5 months ago.
Washington Trust Bancorp shares rose 3.1% alongside other regional banks after softer-than-expected inflation data cooled rate-hike expectations.
May track sector strength while markets price fewer future hikes.
The article attributes the rally to CPI and producer-price softness plus regional-bank earnings read-through, without any new WASH event.
Old Second Bancorp shares gained 3.1% in the afternoon session as inflation data reduced expectations for additional Fed tightening.
Potential for follow-through if rate expectations continue to ease, but limited conviction without OSBC-specific news.
The only cited drivers are macro inflation prints and broader regional-bank earnings read-through; no OSBC-specific catalyst is newly disclosed.
Market effects
Supports a near-term bid in regional banks via lower expected funding pressure and improved net interest income outlook.
Positive read-through for US regional lenders, especially thrifts, as deposit-cost competition is implied to be easing.
Limited direct global linkage; primarily US rates and domestic bank funding dynamics.
Counterpoint
The rally may fade if the inflation data is later revised higher or if the Fed signals it still needs additional tightening despite the print.
