That could be $100k on hand in checking, $600k in stocks/bonds, and $200k in home equity, with $0 in a savings account. Asset allocations that don't use savings accounts are not necessarily 'precarious'.
Also, it's worth noting that most financial advisors do not recommend that you keep a significant portion of your assets in savings accounts. Primary reason is that by not being in assets that deliver returns, you are losing money to inflation, even at these low levels of inflation. (Also, you have to save a ton more if you don't let your money multiply.)
