<prompt> Human: Hi-When I look at my emergency fund balance in a high yield savings account, I often wonder if Im missing out by not putting that money to better use. Because I have a heloc available, does it make sense to reduce the amount of cash in the emergency fund to 2-3 months of living expenses and to redeploy the rest. That way, Id still be able to cover myself for short term issues but could leverage the heloc if it ever was something beyond the 3 months. Yes, I know the first step is to stop looking at the balance in the emergency fund. Thoughts?  <response>: There was a discussion about using HELOC as an emergency fund source on this sub a few weeks back. A few people felt like it was a really good idea mostly people with lots of equity in their homes and otherwise steady and well paying jobs. Others felt like it was overly risky as uclarkbmiller and uellismai mention for the limited potential benefit.If you dont like having a large chunk of change your efund sitting in cash, an alternative to allow you to be more aggressive in investing the market, while still having the safety net of cash in the vent of an emergency is to consider your efund as part of your bond allocation for retirement. There was an interesting analysis comparing the expected returns of a total bond index fund vs a HYSA and the difference was in the 3 range, so not exactly identical products, but relatively similar.For example, if you retirement strategy is currently 7030 stocks to bonds and you have 200K in your retirement accounts, you would have 140K in stocks and 60K in bonds. Now lets also say you have 50K in emergency funds. You could now look at the whole 250K as your portfolio for allocating so 175K stocks and 75K bonds. The difference is the amount kept in cash in your emergency fund would count towards your bond portfolio. So in this example you would sit at 1752550K Stocksbondscash.This strategy essentially keeps the safety of having the efund in cash, while taking the additional risk you are willing to absorb and shifting it to your retirement accounts.
