From Fed Chair Janet Yellen: Monetary Policy and Financial Stability. A few excerpts:

I am also mindful of the potential for low interest rates to heighten the incentives of financial market participants to reach for yield and take on risk, and of the limits of macroprudential measures to address these and other financial stability concerns. Accordingly, there may be times when an adjustment in monetary policy may be appropriate to ameliorate emerging risks to financial stability.
...
[M]onetary policy has powerful effects on risk taking. Indeed, the accommodative policy stance of recent years has supported the recovery, in part, by providing increased incentives for households and businesses to take on the risk of potentially productive investments. But such risk-taking can go too far, thereby contributing to fragility in the financial system. This possibility does not obviate the need for monetary policy to focus primarily on price stability and full employment--the costs to society in terms of deviations from price stability and full employment that would arise would likely be significant.
...
In recent years, accommodative monetary policy has contributed to low interest rates, a flat yield curve, improved financial conditions more broadly, and a stronger labor market. These effects have contributed to balance sheet repair among households, improved financial conditions among businesses, and hence a strengthening in the health of the financial sector. Moreover, the improvements in household and business balance sheets have been accompanied by the increased safety of the financial sector associated with the macroprudential efforts I have outlined. Overall, nonfinancial credit growth remains moderate, while leverage in the financial system, on balance, is much reduced. Reliance on short-term wholesale funding is also significantly lower than immediately before the crisis, although important structural vulnerabilities remain in short-term funding markets.

Taking all of these factors into consideration, I do not presently see a need for monetary policy to deviate from a primary focus on attaining price stability and maximum employment, in order to address financial stability concerns. That said, I do see pockets of increased risk-taking across the financial system, and an acceleration or broadening of these concerns could necessitate a more robust macroprudential approach. For example, corporate bond spreads, as well as indicators of expected volatility in some asset markets, have fallen to low levels, suggesting that some investors may underappreciate the potential for losses and volatility going forward. In addition, terms and conditions in the leveraged-loan market, which provides credit to lower-rated companies, have eased significantly, reportedly as a result of a "reach for yield" in the face of persistently low interest rates. The Federal Reserve, the Office of the Comptroller of the Currency, and the Federal Deposit Insurance Corporation issued guidance regarding leveraged lending practices in early 2013 and followed up on this guidance late last year. To date, we do not see a systemic threat from leveraged lending, since broad measures of credit outstanding do not suggest that nonfinancial borrowers, in the aggregate, are taking on excessive debt and the improved capital and liquidity positions at lending institutions should ensure resilience against potential losses due to their exposures. But we are mindful of the possibility that credit provision could accelerate, borrower losses could rise unexpectedly sharply, and that leverage and liquidity in the financial system could deteriorate. It is therefore important that we monitor the degree to which the macroprudential steps we have taken have built sufficient resilience, and that we consider the deployment of other tools, including adjustments to the stance of monetary policy, as conditions change in potentially unexpected ways.
