Let's say I have an account with $30,000 set aside for long-term unemployment, medical emergency, etc. This account will most likely (and hopefully) remain unused for at least 5-10 years. I could place it into a savings account, but even the best online banks have an interest rate of around 1%, which doesn't even come close to meeting the average inflation rate of 3%. Even short-term bond funds are less than 1.5% annually.
What is the least unsafe investment vehicle where I can place my money that will at least meet a 3% inflation rate?
