What it means
Ordinary inflation is a gradual loss of purchasing power that central banks try to hold near a low target. Hyperinflation is a different phenomenon driven by a collapse in confidence, usually after a government funds its spending by creating money rather than by taxing or borrowing.
Once people expect prices to keep climbing they spend cash immediately, which pushes prices up faster still. For businesses the damage goes well beyond expensive inputs.
Credit terms vanish because nobody wants to be paid in 60 days, working capital is destroyed as receivables lose value before they are collected, and any long term contract priced in local currency becomes a liability. Ordinary accounting also stops being meaningful, since figures from January and December are effectively in different currencies.
Practical responses are consistent across episodes: price in a stable foreign currency, shorten payment terms to days, hold stock rather than cash, and index wages and contracts. Firms that owe money in local currency can benefit, because the real value of their debt melts away, while firms holding local currency receivables are wiped out.
Survival depends far more on balance sheet structure than on trading skill. Accounting standards address the problem through inflation adjusted reporting.
Under the international standard for hyperinflationary economies, accounts are restated into the purchasing power of the currency at the balance sheet date using a general price index. The usual trigger for applying it is cumulative inflation approaching or exceeding 100% over three years.
Hyperinflation almost always ends the same way, through a currency reform, a peg to a stable currency or full dollarisation, combined with credible control of government spending. The technical fix is well understood, but restoring trust is the hard part, which is why some countries relapse.
For managers the practical lesson is that the exchange rate and the money supply give warning long before prices move.
In practice
Real-world examples.
Example
A food importer in a hyperinflating economy reprices its catalogue every morning at the parallel exchange rate. Sales staff quote prices valid for four hours, and any customer wanting 30 day terms pays a 40% premium.
Example
A manufacturer with a large local currency bank loan finds the real burden of that debt has almost vanished within a year. Its lender responds by refusing all new local currency lending and offering only dollar denominated facilities.
Example
A multinational applies inflation adjusted accounting to a subsidiary once cumulative inflation passes 100% over three years. Restating the accounts turns a reported local currency profit into a real terms loss, and group management changes how it rewards the local team.
Think of it
“Hyperinflation is prices rising extremely fast-often doubling in months.
Formula
Calculation
Annual inflation from a monthly rate = ((1 + monthly rate) to the power of 12) - 1
If prices rise 50% every month, the monthly multiplier is 1.5, and over twelve months prices multiply by 1.5 to the power of 12, which is about 129.75. Annual inflation is therefore 129.75 - 1 = 128.75, or roughly 12,875%.
In cash terms, an item costing $10 at the start of the year would cost $10 x 129.75 = $1,297.50 twelve months later. A business that held $100,000 of local currency cash through that year would end with purchasing power of $100,000 / 129.75, or roughly $771, which is why cash balances disappear into stock, foreign currency or hard assets within days.Case study
Seen in the real world.
The following example is illustrative and fictional. Solvera Beverages, an invented bottler operating in a country entering hyperinflation, began the year selling on 60 day credit and holding most of its working capital in local currency cash. Within four months it was insolvent on paper despite selling more cases than ever before.
The mechanism was simple. With prices rising roughly 30% a month, an invoice issued on 60 day terms was collected after prices had risen by a factor of 1.30 x 1.30 = 1.69, so $100,000 of value at the point of sale bought only about $100,000 / 1.69 = $59,000 of goods by the time the cash arrived.
In this fictional account Solvera moved to payment on delivery, priced in a stable foreign currency with settlement at the day's rate, and deliberately held four weeks of raw materials instead of cash. Volumes fell by a fifth as some customers could not meet the terms, but the invented company was still trading when two larger rivals that had kept generous credit terms were wound up.
Watch out
Common mistakes.
- Treating hyperinflation as ordinary inflation with a bigger number, when it changes how a business must be run rather than just what things cost.
- Leaving credit terms unchanged, which quietly hands customers a large discount every single month.
- Reading local currency accounts across a year without restating them, so growth that is purely price driven is mistaken for real growth.
Questions
People also ask.
What actually causes hyperinflation?
Almost always a government financing large deficits by creating money, combined with a collapse in public confidence in the currency.
At what point does inflation become hyperinflation?
The widely used working definition is more than 50% a month, though accounting standards use cumulative inflation of about 100% over three years as their trigger.
Does anyone gain from hyperinflation?
Borrowers with fixed local currency debt and holders of hard assets can gain, while savers, pensioners and anyone holding cash or receivables lose heavily.
