What $100 in 2015 was worth — measured in gold

The price of gold didn't get more expensive. The value of the US dollar fell.

71.3%

of the US dollar's value, gone — measured in gold, since 2015.
It now takes 3.5× more dollars to buy the same ounce.

In 2015, $100 bought 0.09 oz of gold at $1,160/oz. Held as metal, that same money is worth $349 at today's gold price of $4,043/oz (spot as of 2026-08-02).

Same $100. Three rulers.

Measure	$100 from 2015, today	Multiple
Official story — CPI-U (BLS)	$141	1.4×
Money created — M2 money supply	$191	1.9×
In gold — honest weight, valued today	$349	3.5×

The gap between 1.4× (CPI) and 1.9× (M2) is official inflation understating the money actually created. The gap between 1.9× and 3.5× (gold) is the flight to hard money — gold outrunning even the printing.

2015 in the fiat story

QE became permanent policy. The one attempt to reverse it ended in the December 2018 market break and the September 2019 repo blowup — the system had become structurally dependent on new money.
