There's no question that Brazil remains a popular emerging/developing market for international and global investors. Unfortunately, it's all too common for long-term macro calls ("buy Brazil") to have only passing relevance to particular sectors or companies. In the case of Brazilian banks such as Banco Bradesco (NYSE:BBD), lower interest rates hold the potential for compressing net interest margins and bank profit/return on equity (ROE) growth just as we've seen lately in the United States. While investing money in Brazil may make sense today, Bradesco is not looking like the best means of going about it.

A Solid, Diverse Business
While Bradesco is facing some potentially punishing near-term risks, it is, on the whole, a relatively strong bank. The third-largest bank in Brazil, Bradesco holds a mid-teens share of the assets and deposits in Brazil's banking system. While loan losses are elevated in Brazil relative to the U.S., Bradesco has generally done well in managing its credit exposures and boasts a solid long-term record for ROE generation.

Bradesco has also taken a page from the "complete bank" playbook, and has coupled a large bank operation with insurance and pension operations as well. Bradesco is the largest health insurance provider in Brazil (with over 50% share), the third-largest auto insurer (after Porto Seguro and Banco do Brasil (OTC:BDORY)), and the largest pension company by assets (ahead of Itau (NYSE:ITUB), Banco do Brasil and Zurich).

Will Lower Rates Compress Growth?
Bradesco has been reporting respectable results lately. For the third quarter, the company saw 9% year-over-year growth in loans and 1% growth in adjusted net interest income (with a net interest margin nearly double that of large U.S. banks such as Bank of America (NYSE:BAC) and Citigroup (NYSE:C)). Better still, the delinquency ratio has been coming in below long-term trends (down to 4.1% in the third quarter).

Unfortunately, while Bradesco, Itau and Banco Santander Brasil (NYSE:BSBR) have all been seeing pretty good operating conditions, I think investors have reason to worry about results in the next year or two. SELIC rates, the Brazilian version of the overnight lending rate, have been coming down, and this has historically meant net interest margin compression for the commercial banks. So while Bradesco management is talking about ROEs in the high teens or even 20% next year, a repeat of past performance during SELIC declines would suggest downside risk in the mid-teens (and substantial revisions to sell-side earnings estimates).

Making matters worse, the bank doesn't seem to have a lot of options to counteract the spread pressure. Bradesco already operates a pretty efficient bank by Brazilian standards, and marketing moves such as increasing customer credit lines are typically matched pretty quickly by rivals. Lower rates will also pressure profits in the company's insurance operations, just as we've seen in the U.S. with large P&C companies such as Allstate (NYSE:ALL). What's more, a proposal to change the treatment of deferred tax assets and make it easier for Brazilian banks to reach Basel-3 capital standards would likely be of least benefit to Bradesco (and of most benefit to Banco do Brasil).

The Bottom Line
Bradesco is a bank that I would love to love, but the valuation figures just don't support that right now. A return on capital model using a long-range ROE target of 18% suggests fair value of about $17.50 today. Moreover, taking the implied earnings growth rate of 11% from that model and comparing it to the current P/E (13 times) or forward P/E (11.5 times) doesn't suggest a great bargain. Last but not least, using a long-term tangible book value/return on tangible equity regression suggests that Bradesco is, at best, fairly valued on the basis of tangible book value.

All in all, Bradesco is at best fairly valued today, and that's assuming that fears of spread compression (and lower ROE) in 2013 are overblown. The quality of this bank makes it a good one to watch, however, particularly if that spread compression leads to significant cuts in estimates and underperformance in the shares.
