The National Australia Bank Ltd (ASX: NAB) share price is having an August to remember.
At close of trade on Friday, shares in the big four bank were trading for $27.41 – down 0.36%.
For context, the S&P/ASX 200 Index (ASX: XJO) ended 0.29% higher. Since the beginning of the month, NAB shares have risen 5.78% while the benchmark index is 0.85% higher.
This golden August comes off the back of NAB announcing a $2.5 billion share buyback at the end of July. The news saw the NAB share price lift by the end of the day.
Let's see what's been affecting NAB this month.
The month so far for NAB
The first significant story that was material to the NAB share price was its confirmation it would purchase the Citigroup Inc (NYSE: C) Australian consumer business for $1.2 billion.
As Motley Fool previously reported, NAB announced it would buy Citi's home lending portfolio, unsecured lending business, retail deposits business, and private wealth management business for the value of the net assets plus a premium of $250 million.
Citigroup's Australian consumer business has lending assets of approximately $12.2 billion ($7.9 billion in residential mortgages and $4.3 billion in unsecured debt) and deposits of about $9 billion.
As part of the deal, Citibank senior management and around 800 staff will join NAB on completion. Citigroup's institutional business in Australia is not a part of the deal.
The purchase is subject to regulatory approval including from the federal Treasurer, the Australian Prudential Regulation Authority (APRA), and the Australian Competition and Consumer Commission (ACCC). If all goes as planned, the deal should be completed by March 2022.
Other news that affected the NAB share price included the results out of competitor Commonwealth Bank of Australia (ASX: CBA). In fact, most ASX bank shares lifted that day.
Finally, NAB released a third-quarter trading update. This was not price-sensitive.
NAB's revenue fell 1% as declines in markets and treasury (M&T) income outweighed higher volumes and margins in its lending businesses.
The bank's net interest margin (NIM) was broadly stable, reflecting lower deposit and funding costs, partly offset by the impact of low-interest rates and home lending competition.
NAB share price snapshot
Over the past 12 months, the NAB share price has increased by 55.3%. It has outperformed the ASX 200 by 30 percentage points over the period. Year-to-date, however, it has underperformed the ASX 200 by about 3 percentage points.
NAB has a market capitalisation of approximately $90.7 billion.
