The National Australia Bank Ltd (ASX: NAB) share price fell off a cliff throughout the month of June.
Despite the bank not releasing any announcements, investors offloaded its shares to an 11-month low of $25.43 on 17 June.
For context, NAB shares started the month from 31 May's market close at $31.26 and ended at $27.39 on 30 June. This represents a decline of around 12% which can be considered sizeable for a blue-chip share in a short time frame.
While NAB shares have since recovered some lost ground, they are still trading 0.88% lower today to $27.49.
What dragged down NAB shares in June?
The NAB share price finished lower than it started last month, dragged down by weakened investor sentiment.
An aggressive rate hike by the Reserve Bank of Australia (RBA) to cool inflation levels spooked the market.
The RBA ramped up the official cash rate by 0.50% to 0.85% on 7 June. This led to NAB shares tumbling 3.25% on the day of the news.
However, the blood-letting didn't stop there with the bank recording a loss over the next five business days.
In total, NAB shares declined 16.4% from 7 June until 15 June.
And the bank wasn't the only ASX 200 financial share to suffer.
For context, the Commonwealth Bank of Australia (ASX: CBA) share price dropped 14.21% over the same period while Westpac Banking Corp (ASX: WBC) and Australia and New Zealand Banking Group Ltd (ASX: ANZ) reversed 19.02% and 13.7%, respectively.
Notably, the RBA is meeting today to decide whether it will lift interest rates from the current level.
Most economists are tipping another 0.5% rate hike to 1.35% which will likely have a negative impact on the ASX.
