    This study doesn't correct for baseline exponential decay due to inflation, to better highlight the meaningful variations. By comparing based on 1914 dollars it also causes old variations to be relatively more extreme and newer inflationary events to look less extreme. You must compare apples to apples.

    Finally the events are quite cherry-picked. It is a conclusion looking for a result, when the statistical reason for choosing those 4 events simply isn't evident when you look at the data itself. There is no mathematical rule you could apply to your dataset that would distinctly highlight those 4 periods.

    • vessenes 8 minutes ago

      Yes, a log chart would be better. That said, apples cannot be compared in this case; probably very few of us would choose to go back to 1914. A Tesla model Y would cost $1,680 in 1901 dollars, but would have been worth millions of those same 1901 dollars. Or nothing, depending on how much charging tech you could fit in the frunk. Many quality of life items are not covered by PPP (or money supply or other measures) adjustments.

      I think this graph shows the "apples to apples" comparison:

      https://www.officialdata.org/us/inflation/1800?amount=1

      Doing a spot check, this means $1 in in 1913 is equivalent to roughly $32.83 today.

    This supports my hunch that the current Iran war creates a lethal trifecta that could potentially cause a dollar collapse. 1. Massive military overspend. 2. Petrodollar squeeze (Strait of Hormuz). 3. Allies pulling out: Europe and the Gulf diversifying both their investments and defense purchases.

    #1 creates oversupply of dollars and #2 and #3 lower demand. This study supports the idea that wars can indeed destroy purchasing power.

      Iran is also playing its own Uno card here by saying that it would consider allowing some oil and gas shipments through the Strait if they have been bought with Chinese Yuan, than the US dollar. ( The Islamic Republic may grant safe passage to oil tankers if the cargo is traded in Chinese yuan - https://www.lbc.co.uk/article/iran-allow-chinese-ships-hormu... ).

      • johnmaguire an hour ago

        I've never heard the expression "to play one's Uno card." Is this a play on "to play one's Trump card"? I can understand why this phrasing could cause confusion, but want to make sure I'm not missing something.

          In Uno, you're supposed to say ‘Uno’ as you play your second to last card (indicating you are close to winning).

          Trump attacked Iran thinking that this would somehow be good for the US, except it's weakening the petrodollar because it's pushed Iran to simply accept Yuan for oil.

            One of the previous times the US attacked Iran, it was because Iran wanted to accept Euros for oil.

        This is particularly funny if you consider petrodollar to be a bad deal for US, not a good one. Ironically, if yuan becomes new petroleum currency, it might hurt Chinese long term.

        • maxglute 39 minutes ago

          Petro-yuan =/= reserve currency.

          USD reserve = print USD for everything liquidity to sustain debt financed existence where Triffin hollows out industry, and financialize everything because having stupid amount of liquidity incentivizes certain behaviors.

          Petro-yuan = PRC gives swap lines to trusted partners to buy oil denominated in yuan in exchange for things like resources. Hormuz ships ~1 trillion USD worth energy that needs "swapping" - incidentally PRC imports around ~2-3 trillion, more than enough to cover.

          So think petro-yuan = PRC gives trusted countries with resources that PRC bonds credit lines to buy yuan denominated energy (possibly at discount), in return they guarantee PRC resources or other commercial/geopolitical arrangements. It will be narrow, not like USD brrrting reserves.

          This benefits PRC because get to have leverage over "need" transactions (countries need energy to survive, it's no negotiate) while US keeps supporting "want" transactions by reserve debt servicing blackhole that US cannot extricate itself from until it debases / technical defaults. PRC best game plan is... assume privileged part of exorbitant privilege, while leaving US the exorbitant.

          • kasey_junk 18 minutes ago

            The problem with that plan is that no one wants to trade hard commodities for a currency that can’t be spent. One part of the dollars appeal is that it spends the world over. The sanctioned countries frequently have more liberal access to dollars than to unsanctioned yuan.

            So no one is going to take up a lot of yuan trade unless that changes or they are forced to.

            But that puts China in a bind. Liberalizing their currency is going to require very careful and slow actions, China threads this needle now in a very fraught way. If they openly start trading oil at any real size in yuan that will break their peg as you’ll be able to trade through the oil markets.

            This is the main reason there isn’t more petro yuan already, it’s bad for China.

              You can buy from China though. And China is the largest import trading partner for the majority of countries in the world. They literally don't need to do anything to prop up a "petro-yuan".

        • cjbgkagh an hour ago

          The petrodollar confers a huge advantage to the US, which is the whole point of it. It soaks up liquidity and allows the US to export inflation which allows it to be in the insanely profitable business of printing money. An argument could be made that this is corrupting and economically distorting to society resulting in a net negative but there is no guarantee that the same corruption would undermine China in a timely manner. I think the effect would be rather muted provided that the US remains world hegemon but if the US would lose the petrodollar and credible force projection at the same time we will shift from the current looting stages of collapse to the free for all stage of collapse. Or put another way, from a managed decline to an unmanaged decline.

          Agreed. Which is why the Chinese do NOT want their currency to become the Petrodollar or world's reserve currency. They know that that is what destroyed US Manufacturing. China wants to maintain their manufacturing dominance. They've seen what de-industrialization has done to the US.

          • ImJamal an hour ago

            How are you connecting the petrodollar and US manufacturing? US manufacturing was destroyed because companies closed their factories in the US and used factories in China because labor was cheaper and they were less regulated.

            • mekdoonggi 33 minutes ago

              Petrodollar creates demand for dollars. This is demand that no other currency gets. That's why US production is expensive vs other countries. China labor is cheaper and it is less regulated, but the petrodollar exacerbates the problem.

            • lvass 43 minutes ago

              Because it increases US workers relative (to other countries) wage. Though with current automation levels this may be a lesser problem.

        Only cheap labor can bring manufacturing back to the US. Are Americans willing to work in factories for the same wages as the Chinese and Indians? I don't see it happening.

          Under conditions of free trade with low-wage countries.

          Free trade with low-wage countries is a policy choice, but a lot of people confuse it for a natural law.

        • vessenes 6 minutes ago

          That is the point of cheapening the dollar, BTW. The local wages can stay 'high' dollar denominated, but the euro-denominated value of those wages drops. It was for some time the strategy of the Chinese central bank; you can keep export good costs low by controlling your currency to weaker. The trick is to do that while everyone is paying you for your stuff.

        • nradov 17 minutes ago

          Cheap labor wouldn't necessarily bring manufacturing back to the USA. Over time much of the labor can potentially be automated. But environmental and zoning rules effectively ban entire industries such as metal casting. If we want those industries back then we'll need a major realignment of public policy that goes beyond just labor.

        • devsda 12 minutes ago

The real economies are tied to a stronger middle class and national security. That’s the thesis as I understand it.

          The United States is current getting the base material for its entire economy from a country that is openly at war with it: China. If the US attacked East Tiawan because East Tiawan attacked Taiwan, East Tiawan would simply stop exporting rare earths, silver, steel, and electronics to the US. As a result the US needs to manufacture at home. So too does the EU.

        • roncesvalles 35 minutes ago

          I'll dig down 3 levels of "why".

          The endemic anti-intellectualism among white communities (especially rural and southern) has resulted in a steady decline of white people in well-paying professions in America. If you count the Jewish as a separate group, white people are likely a minority in corporate America. Combined with social upliftment of other groups ("wokism") and the opioid crisis (that has disproportionately affected hinterland communities but immigrant groups seem immune to), white people are sliding down the American totem pole. Trumpism, alt-right, anti-woke, and the general resurgence of racist rhetoric are basically just reactions to all this.

          These people want manufacturing because manufacturing is largely considered a "white people sport". If America becomes a manufacturing-first society, the hope is that it puts white people at the front and center of American society again.

      #1: US military war spending concerns are largely overblown. It's expending what it already has. The spending is mostly on its own internal industry i.e. the US economy (with due respect to broken window fallacy). It arguably makes it all back from the increase in oil prices.

      It's a very different thing to fire a $5m missile that you imported vs one that you made domestically with all-domestic components and labor.

      I hate to admit it, but it's much less that the US is great because it's the reserve currency, and much more that the world reserve currency is the dollar because the US is what it is.

      Weapons are expensive, and it only makes sense to buy them from a country that specializes in them. And a country that makes weapons at huge scale is likely to be big enough tilt the direction of the country to be all the ugly things the modern US military industrial complex is.

      • thisislife2 an hour ago

        Is China really dependent on middle-east oil? I read that they had been diversifying in preparation for an energy resource fight for some time now. For example, they've massively invested in Solar power generation, are building a 300-400 billion dollar gas pipeline from Russia, already buy a lot of oil to from Russia, and also purchased from Venezuela (though how that's going now is anybody's guess). They also have a good relationship with most of the players in the middle-east and helped repair ties between the Saudis and the Iranians.

      • znnajdla an hour ago

        That would be a double whammy for America then: a devalued dollar and higher oil prices. Both cause inflation.

            Inflation is about what goes on inside the country. So you can have inflation internally while the domestic currency strengthens against foreign currencies, and vice versa.

            If your currency is falling against foreign currencies but prices are also dropping domestically, you get deflation. This was happening in China a couple of years ago, and they were exporting this deflation to other countries.

  • Booktrope 23 minutes ago

    Whoever wrote this article seems to think a strong dollar is fundamental to a strong economy. But, notice where it is on this timeline the only prolonged strengthening of the dollar that shows up. Yep, you've got it, the depth of the great depression. And, notice where the WWII and postwar weakening of the dollar led -- that's right, to in many ways the most prosperous economy the world has ever seen.

    Because we try to figure out how things like "strengthening" and "weakening" of the dollar fit in, and we actually have policies much more intelligent than, weaking of the dollar! Collapse is imminent!

    Note that most of this period falls before the modern inflation target was established in 1995. In the past 30 years we've had 75% accumulated annual inflation (aka prices have increased be a factor of exp(0.75) = 2.1) of which 16% (aka 21% of the total) took place during an inflation excursion (which lasted 2.5 years aka 8% of the total time period).

          • zer00eyz 6 minutes ago

            Wage data, population growth, overall consumption, credit (and guarantees against it) are all drivers of inflation.

            Look at student loans vs the cost of college:

            1958: Federal program to encourage science and engineering. 1976: Remove restrictions on bankruptcy dismissal of this debt. 2005: Same rules for private loans.

            Today college has a (as someone here so eloquently put it) a cruise ship ascetic, and has far more "administration" than "eduction" in terms of raw staff.

            Tv went from an expensive box (fixed cost) to cable (monthly fee) to on demand programing (several monthly fees, and with ad's).

            A phone used to be a single item in your house with a monthly fee. It was an item so durable that you could beat a robber with it and still call the police (see old att, black rotary phone). Now its an item per person in a household, that you can easily loose, might break if you drop it, and costs any where from 200 to 1500 dollars.

            None of this is inflation in the traditional sense, but it does impact the velocity of all money in the system, and puts pressure on individual spending in a way that isnt even accounted for in this chart.

    • cyanydeez an hour ago

      I believe the broader reason for an inflation target is to increase the value of "doing something" as opposed to "doing nothing" with money. Of course, like most policies, this acts on people with way too much of it and skews the perception of control and locus of control to those entities with too much.

      • PowerElectronix 44 minutes ago

        That's a bit of falacy. If inflation target were 0%, people would still have an oportunity cost of doing nothing compared to deposits, bonds and other "zero risk" investments. You just stop punishing people that has their wealth in form of cash savings.

        2% is an arbitrary number that just looks good and seems to work. The issue is that that target is very much not set into stone, as central banks often disregard or take too long to take action when inflation shoots up. And never, ever do they try to compensate afterwards with a lower target for a time.

        You can have a government spend way beyond its income making inflation spike, eroding their own debt at the cost of cash savings purchase power and the central bank just sit put and wait until inflation runs too hot to then increase rates that then cut way before inflation is on target. As we are having right now in basically every country on earth.

      • siruwastaken an hour ago

        Not to reply against you, just to add clarification. This is the reason why a slightly positive inflation rate is normally targeted. Theoretically, it would be entirely possible to target 0% inflation, but then you are so close to possible deflation, that most people would simply save up money instead of buying things from the economy.

    I compiled 1,357 monthly CPI observations from 1913 to 2026 (BLS data via FRED). The common narrative is that inflation slowly erodes purchasing power over time. The data tells a different story. Four concentrated episodes — WWI, WWII/post-war, the Great Inflation (1968–82), and post-COVID — account for 72% of total cumulative price increase, despite spanning only 29% of the time period. The dataset includes regime classification, episode tagging, and a decomposition analysis. Full CSV available for download.

      IMO the first graph would make a lot more sense when plotted in log scale.

      Also this way of framing "As of February 2026, the US dollar has lost 96.9% of its purchasing power relative to January 1914. This means that $100 in 1914 would buy only approximately $3.05 worth of goods today" is of course math-correct but difficult to understand intuitively.

      I think it makes more sense to explain it in the opposite direction or in both directions: "$100 in 1914 would buy only approximately $3.05 worth of goods today, or equivalently, $100 in 1914 is worth ~ $3278 nowdays (because 100 / 3.05 ~= 32.78 "

      This also makes it easier to understand that the term "millionaire == person that has 1 million USD" only makes sense around 1914, because the equivalent amount of wealth nowdays would be "millionaire == person that has 32 million USD"

      Anyways, I liked a lot this visualization https://mlde8o0xa4ew.i.optimole.com/cb:VNTn.d9a/w:auto/h:aut... that visualizes the compression in time of the big value changes.

        It's still a bad chart because of the "the great inflation destroyed more value than both world wars combined" claim, for two reasons:

        1. It's not clear (from the chart at least), that the claim is true. 20.0% + 18.1% = 38.1%, greater than 30.2%, but the quote claims otherwise. True, the red and orange segments cover more than just ww1 and ww2, but if more granular data is available why not show it?

        2. "destroyed more value" might be technically true if we define "value destroyed = inflation", but it's a non-intuitive definition to use. If you asked someone about the value destroyed in ww1/ww2, they'll talk about europe being bombed out, not higher inflation.

        Also if you had that $100 in 1914 dollar coins it would actually be worth $5,400 in silver.

        If you had $100 in 1914 $10 coins you would have $24,800 in gold.

        Fair point on Pareto distributions. The distinction I'd draw is that these aren't random clusters — they map to specific policy regimes (wartime monetization, oil shocks + Fed accommodation, post-COVID fiscal expansion). The concentration isn't statistical noise, it's identifiable macro episodes. The dataset tags each month by regime if you want to dig in.

      Really not interesting analysis. Four "concentrated episodes" totaling 30 years, hardly "concentrated episodes", especially when you have a "concentrated episode" that lasts for fifteen years. It's extremely unsurprising there are periods of inflationary growth that's higher, and some lower.

  • milesskorpen 2 hours ago

    1950-1985 and 1985-now are pretty steady. Decreased inflation volatility over time.

    I think your chart shows the "that inflation slowly erodes purchasing power over time." That doesn't mean there aren't periods of change - if you study economic history at all you know about the Great Depression and stagflation - but for ~50 years it's been pretty well managed.

    • eykanal an hour ago

      The purchasing power of $3.05 in 1914 would require $100 in today's time. A bag of "stuff" worth $100 today could have been purchased for $3.05 in 1914.

      Technically, it does mean that $3.05 from 1914 is worth $100 today, but that's not a useful way of thinking about this. I.e., if your great-grandfather put $3.05 in an envelope in 1914 and you opened it today, it's still $3.05 worth of money (ignoring wheat pennies being a collectors items and whatnot).

    • kogus an hour ago

      I'm pretty sure you are right. Or to emphasize the devaluation, "$100 today would be worth only $3.05 in 1914."

      I think it is astonishing that we accept that in a best case scenario of sustained 2% inflation, we are literally planning for the value of the dollar to be cut in half every 36 years.

        Our system is designed to encourage asset ownership, not cash saving. If you stuff it under a mattress for 36 years, yeah you'll get fleeced. But buying assets is the way to keep up; an investment of $100 in the S&P500 in 1990 and never touched would be worth $4,120.93 today.

            "worth" can have two meanings in this context. $100 from 1917 can be worth exactly $100 today. Or it can be worth what you can buy with it.

            Some folks will see a $100 bill from the era and see an old $100 bill. Some folks will imagine what that $100 took to save back then, and what it bought.

            FWIW my brain automatically went with "the goods that can be bought with $100" - such as what I could buy in a grocery store today with $100 would be about what I could buy with $3 back then.

            I never considered the other reading until this thread. It was obvious to me the author meant "you can buy 97% less stuff today with the same $100".

      I think probably the interest rate is higher, but the value as a proportion of the starting value on LHS is less significant, compared with the periods you mention. If you look at the monthly interest rates at the bottom, it seems to support this notion.

  • WarmWash an hour ago

    The value of the dollar over time is largely meaningless unless you are a dollar investor (i.e. sit on lots of cash in consumer tier bank accounts). Generally once you have enough cash that this would meaningfully impact you, you are already beyond sitting on cash.

    At the end of the day, the dollar or any other currency, is just a conversion tool for [value created] to [goods/services received]. A ratio of 3/1 is equivalent to a ratio of 300/100, even if 3 and 1 are 99% smaller than 300 and 100. The numerator and denominator can move out of sync, creating periods of strain and arbitrage while they equilibrate, but what really matters is how much xyz you get per hour of work at job abc. And overwhelmingly we are leagues beyond 1914 in that regard.

    • mothballed an hour ago

      It's meaningful because you pay capital gains on nominal increase in dollar value even if there is no real change in value. Inflation is thus a tax on realized non-gains at roughly 1/5th the cumulative inflation.

    Fiscal deficit. That is the main reason by far of Dollar's destruction. Everything else is wrong or over-thinking.

  • jawns an hour ago

    Another way to frame this is that during inflationary episodes, debt became easier to repay.

    My parents bought a house in the 1970s. Because of the inflation that occurred during that time, incomes and expenses rose, yet long-term debt obligations such as fixed mortgages remained unchanged; their mortgage payment was the same in year 30 as in year 1.

    I guess another way to say it is that during an inflationary period, the people who HAVE money suffer the loss of its purchasing power. But the people who OWE money benefit from the dollar not being what it used to be.

    Why do wars tend to devalue the dollar?

    • t-3 an hour ago

      In addition to the already-stated causes of government issuing currency necessary to meet war spending and the fact that war spending produces destruction of economic capability rather than development, wars tend to introduce trade barriers and divert resources away from productive tasks. Whether barriers are legal (tariffs, embargoes), or simply higher premiums due to increased risk, less trade happens, which raises prices (inflation). Economists also really hate number-go-down even when down is good, so policy is oriented towards making sure deflation never gets a chance in the interwar development periods.

    • kmeisthax an hour ago

      Only half of the incidents listed were actually full-scale wars (WWI and II). The other two incidents are an oil shock and a pandemic.

      The commonality between all four of these incidents is that they correspond to severe supply shocks:

      - During WWI and WWII, industrial supply was rerouted by force to the war effort, leaving normal consumer demand unfulfilled.

      - During the oil crisis of the 70s, a critical energy input to the American economy massively increased in price due to sanctions placed on America.

      - During the COVID-19 pandemic, a significant chunk of workers were paid not to work, as a form of deliberate supply destruction to avoid the spread of a novel coronavirus.

      In a "normal" economy, supply is flexible enough that you can print money and nobody even notices. The supply curve is smooth and gradual, so prices only rise a little. When supply is constrained, however, prices rise to whatever value is necessary to curtail demand, because they have to. The supply curve is a brick wall.

    The most notable anomalous event if you zoom back to more like 1814 instead of 1914 is that ever since the US completely decoupled from the gold standard, it switched into purely inflationary mode rather than often bouncing back. From the 1800-1900 pretty much the entire time was spent at worst 1/2 to 2x the average value. Far less variance than after the introduction of federal reserve and taking off the gold standard, where purchasing power was destroyed to something like <1/10th of the century average.

    > The Great Inflation of 1968–1982 alone accounts for 30.2% of all cumulative purchasing power destruction since 1914 — more than WWI and WWII combined. During this 15-year period, the CPI rose from 34.1 to 97.7, nearly tripling the price level.

    In 1971, the United States ended the convertibility of the US dollar to gold, effectively bringing the Bretton Woods system to an end and rendering the dollar a fiat currency.

    This allowed for the global reserve currency to float which allowed for global credit expansion at the cost of the dollar value but with the benefit of more overall dollars (monetary velocity increasing)

    This is what politicians want because it makes the dollar printing machine the most powerful thing, hence why everyone hung on the fedchair words every few months.

    So the USD is already hyperinflated but the price relative to other currencies is still high.

    Once that price collapses (and it eventually will and increasingly soon) the entire US will look like the rust belt.
