NEW YORK (ETF Expert) -- An overwhelming majority of commentators seem convinced that interest rates will remain elevated. Some have suggested that 2.72% on a 10-year yield is merely a pit stop on the way to a year-end close of 3.25%.I believe that global economic uncertainty coupled with disappointing corporate guidance will push the 10-year back down to 2.25% by year's end. For that matter, I believe the Federal Reserve will wait to slow its bond-buying program until 2014. At the moment, I appear to be in the minority. Still, there are a great many individuals who require an income stream from their investments, whether rates fall, settle in at their current levels or creep higher. For that reason, I think it is important to identify income-oriented ETFs that are less sensitive to spikes or long-term changes in Treasury bond yields. The first income-oriented possibility is PowerShares Senior Bank Loan ( BKLN). In the bond swoon that has seen 10-years rise 100 basis points, BKLN has only forfeited 1.6% in price appreciation. The iShares 7-10 Year Tresury Bond ETF ( IEF) is down 7.5%. While losing 1.6% on price may not be desirable, one is picking up roughly 4.4% in annualized income. In fact, if you haven't purchased BKLN yet, even if the 10-year rose to 3.25% by year's end, the annualized income of the remaining months in the year could still wind up generating 1.5% in income over the six months. If the 10-year holds flat, one might expect 2.2% in the 6 months. If the 10-year reverts to 2.25% as I suspect, BKLN would likely garner 3% in total return over a half-year, which is similar to the 6% annualized that many income seekers pursue. Senior bank loans are floating-rate securities from below-investment grade companies. Unlike "junk bonds," these debts have seniority over other creditors and the debts have been secured by collateral (e.g. real estate, etc.). Better yet, since the debt "floats" over short time periods, prices and yields can rise alongside interest rates. What makes BKLN particularly attractive include distributions that occur monthly as well as diversification across 135 holdings. The second income-oriented ETF is actually an exchange-traded note, UBS E-TRACS Alerian MLP ( MLPI). While it is widely assumed that energy pipeline partnerships are interest rate-sensitive (and in truth, they often are), there are plenty of instances when these high-yielders have stood their ground. For example, the folks at Credit Suisse pointed out that when rates had been rising and the Fed had been tightening between mid-2004 and mid-2007, MLPs managed to outperform aggregate bond indexes as well as the S&P 500. Similarly, over the last two months of rapidly rising interest rates, Vanguard Total Bond Market ( BND) logged -3.6% while the S&P 500 SPDR Trust ( SPY) registered 1.2%. Yet, MLPI picked up 1.8%. In truth, domestic demand for natural gas as well as other products pushed through pipelines in the U.S. is growing. It follows that the dividends that pipeline partnerships have to pay out can go up over time; price appreciation does not necessarily kill a reliable yield. And while there may be a variety of Alerian pipeline partnership ETFs and ETNs to choose from, the one with the best relative strength today is MLPI.
