Like a lot of folks I've been bummed by bond performance recently (well, all of my investing life if I'm honest). I've been 90/10, most of the time, but drifted up towards 80/20 as we near FIRE. That said, much of our 20% is in "safe" things like I-Bonds and GFICs (the Canadian equivalent of CDs). And I'm not sweating it too much, as my current plan is to use much of our bond allocation (and perhaps some of our taxable equities) to pay off our house in 3.5 years. With that short of a time horizon, I can accept that I don't have great options available to me, and I've been pleasantly surprised by the I-bonds. Most of the rest of our bonds are in LTTs and TIPS.
Once we pay off the house, I'm not sure what I'll do with our FI portion. My current plan is to be retired, and to keep our AA around 80/20, with half of that 20 in GFICs / high interest savings. I want more cash because 1) I don't want to have to sell equities low and 2) I don't want to have to exchange currencies at bad times (most of my investments are in USD while we spend in CAD). We'll see how it all shakes out, though.
