Balance Sheet Growth
Our balance sheet remains a source of strength. Total assets were $12.36 billion at June 30, 2022, compared to $12.57 billion at March 31, 2022, and $12.42 billion at June 30, 2021. At June 30, 2022, portfolio loans were $7.50 billion, compared to $7.27 billion as of March 31, 2022, and $7.19 billion as of June 30, 2021. Amortized costs of Paycheck Protection Program (PPP) loans of $7.6 million, $31.8 million, and $390.4 million are included in the June 30, 2022, March 31, 2022, and June 30, 2021, portfolio loan balances, respectively. During the second quarter of 2022, Busey Bank experienced another strong quarter of core loan1 growth of $249.1 million, consisting of growth in commercial balances2 of $151.3 million and growth in retail real estate and retail other balances of $97.8 million. Growth was principally driven by our Northern Illinois and Central Illinois regions. As has been our practice, we remain steadfast in our disciplined underwriting.
Average portfolio loans were $7.38 billion for the second quarter of 2022, compared to $7.16 billion for the first quarter of 2022 and $6.89 billion for the second quarter of 2021. The average balance of PPP loans for the second quarter of 2022 was $19.3 million, compared to $51.5 million for the first quarter of 2022 and $496.2 million for the second quarter of 2021. Average interest-earning assets for the second quarter of 2022 were $11.45 billion, compared to $11.70 billion for the first quarter of 2022, and $10.45 billion for the second quarter of 2021.
Total deposits were $10.40 billion at June 30, 2022, compared to $10.59 billion at March 31, 2022, and $10.34 billion at June 30, 2021. Fluctuations in deposit balances can be attributed to the retention of PPP loan funding in customer deposit accounts, the impacts of fiscal stimulus, inflation and related economic effects on our customers, as well as typical seasonality aspects within our portfolio, and other core deposit1 growth. The Company remains funded substantially through core deposits1 with significant market share in its primary markets. Core deposits1 accounted for 98.9% of total deposits as of June 30, 2022. Cost of deposits was 0.08% in the second quarter of 2022, holding steady with the first quarter of 2022. Excluding time deposits, the Company’s cost of deposits was 0.05% in the second quarter of 2022, an increase of 0.01% from March 31, 2022.
During the second quarter of 2022, we redeemed $40.0 million of 3.75% senior notes which matured on May 25, 2022.
Net Interest Margin1 and Net Interest Income
Net interest margin1 for the second quarter of 2022 was 2.68%, compared to 2.45% for the first quarter of 2022 and 2.50% for the second quarter of 2021. Excluding purchase accretion, adjusted net interest margin1 was 2.66% for the second quarter of 2022, compared to 2.41% in the first quarter of 2022 and 2.43% in the second quarter of 2021. Net interest income was $75.9 million in the second quarter of 2022, compared to $70.1 million in the first quarter of 2022 and $64.5 million in the second quarter of 2021.
The Federal Open Market Committee (FOMC) raised rates during the first quarter of 2022, for the first time in three years, and again in both May and June 2022. Rising rates have a positive impact on net interest margin1, as assets, in particular commercial loans, reprice more quickly and to a greater extent than liabilities. Given the timing of the FOMC meetings in May and June, the full benefit of the associated movement in rates to our net interest margin will be largely realized in subsequent quarters. In general, net interest margins1 have been impacted over the last two years by PPP loans, significant growth in the Company’s liquidity position, and the issuance of debt. Factors contributing to the 23 basis point increase in net interest margin during the second quarter of 2022 include:
| ● | Loan growth and higher new volume and repricing rates which contributed +23 basis points |
| ● | Increases in the cash and securities portfolio yield which contributed +7 basis points |
| ● | Reduced volume of PPP loan forgiveness which contributed -3 basis points |
| ● | Reduced recognition of purchase accounting accretion which contributed -2 basis points |
| ● | Increase in borrowing costs contributed -2 basis points |
Future FOMC rate decisions are expected to continue to be a net positive to net interest margin. Based on our most recent Asset Liability Management Committee (ALCO) model, a 100 basis point parallel rate shock is expected to increase net interest income by 4.3% over the subsequent twelve month period. Market competition for deposits has started to increase and deposits betas are likely to increase going forward, which is factored into our ALCO model. In the second quarter of 2022, our interest-bearing non-maturity deposit beta was 2.7%.
