Which households are most exposed to the inflation tax?
Core argument: Treasury holdings peak at 6% of net worth for the oldest and wealthiest households, in the fifth wealth quintile.
For households in the top wealth quintile, Treasuries become a more important element of their balance sheets, topping at 6% for the oldest and wealthiest group (the fifth quintile). However, for the second to fourth wealth quintiles, holdings of Treasuries as a share of net worth tend to fluctuate with age: increasing from the 20s age group to middle age, but then decreasing gradually. This transition likely reflects the change in household asset holdings over the life cycle. We can interpret the numbers in the second figure as showing how much households’ wealth in each group is exposed to the implicit inflation tax through their Treasury holdings. Overall, the older, wealthiest households and the groups that are both middle-aged and middle wealth seem to be the most exposed.
