Sometime in the next 12 to 20 months (or even sooner), we’re looking at the very real possibility of interest rate hikes. If you’re caught off guard and holding the wrong exchange traded funds (ETFs), it could wind up being costly.

What goes down must eventually come back up, right? The rock-bottom interest rates we’ve been enjoying for the last few years aren’t going to last forever. They won’t be as necessary to help goad an economic recovery, so as the picture brightens both here and around the world, they’ll naturally have to go back up.

Avoid Surprises. Expect the “Unexpected.”

If it weren’t so sad, it would be amusing to see the financial headline writers’ competition to feign the most astonishment when the most obvious news is reported.

Direxion announced the expansion of its fixed income product line on Thursday with the launch of two leveraged ETFs targeting a short-term Treasury index. The Direxion Daily 2-Year Treasury Bull 3x Shares (TWOL) seeks 300% of the daily performance of the NYSE Arca Current 2-Year U.S. Treasury Index, a benchmark that consists of the most recently issued 2-year U.S. Treasury notes. The Daily 2-Year Treasury Bear 3x Shares (TWOZ) seeks 300% of the inverse of the daily performance of the same index.

The addition of TWOL and TWOZ expands Direxion’s leveraged fixed income offerings to six funds, joining 300% and -300% ETFs linked to the the NYSE Arca Current 10-Year U.S. Treasury Index (TYD and TYO) and NYSE Arca Current 30-Year U.S. Treasury Index (TMF and TMV). While most leveraged ETFs are linked to equity benchmarks, leveraged bond funds have seen a surge in popularity over the last year. According to the latest industry figures from the National Stock Exchange, leveraged bond ETF assets exceed $5 billion, with the vast majority of that amount in inverse funds. The ProShares UltraShort 20+ Year Treasury (TBT) took in more than $2 billion alone last year.
