What it means
A bubble forms when the prices of assets such as shares, property or commodities rise far above what the underlying earnings or rents can justify. When it bursts, prices fall sharply and many investors lose money.
An echo bubble is what happens when the same enthusiasm, and often the same cheap money, finds a new home soon after the first collapse. The classic story people tell is of low interest rates.
After one bubble pops, central banks may cut rates to protect the economy, and the cheap borrowing that results can fuel a rush into a different asset class. Savers and investors who were burned in the first episode may also chase quick gains in the new market to make their losses back.
The term is an interpretation of events rather than an official category. Economists often disagree about whether a particular boom was an echo of the one before, or simply a separate cycle that happened to follow it.
Because of that, the phrase is usually used in commentary and debate, not in formal accounting or regulation. For a business, the lesson is practical.
If your customers, suppliers or lenders are caught up in a fast-rising market, your own results may be flattered by conditions that will not last. A company that sells to property developers during a boom, for example, should plan for the day when orders fall.
Warning signs are fairly consistent. Prices rise much faster than incomes or earnings, borrowing grows quickly, ordinary people who never followed the market suddenly start to talk about it, and promises of easy returns multiply.
No single sign proves a bubble, but several at once call for caution. It is also worth remembering that the existence of a bubble can only be confirmed in hindsight.
Prices that look too high may keep rising for years, which is why timing the end of a bubble is so hard even for experienced professionals.
In practice
Real-world examples.
Example
After a stock market crash, borrowing costs fall and money flows into housing. Within a few years property prices climb far faster than rents or wages, and commentators describe the boom as an echo of the earlier share price bubble. Lenders in that market begin to relax their standards because recent price rises make the collateral look safe.
Example
A technology fund that lost heavily when a sector collapsed moves its money into a newly fashionable asset class. Other investors do the same, and prices surge on expectations rather than earnings. Observers note that the behaviour looks very familiar. Several commentators write that the story sounds uncomfortably like the one told a few years earlier.
Example
A building materials supplier enjoys record orders during a regional property boom. The finance director treats the extra profit as temporary, and builds a cash reserve rather than committing to a permanent expansion. The firm also agrees not to sign any long leases on new yards until the market has settled.
Case study
Seen in the real world.
This is a fictional story. Meridian Timber Supplies, an invented company, grew quickly when a wave of speculative house building followed a stock market crash in its region. Orders doubled in eighteen months, and the owners were tempted to buy a second sawmill.
The finance director studied earlier property booms and noticed that this one looked like an echo of the previous bubble, with rapid price rises, loose lending and many first-time speculators. Instead of borrowing to expand, the company built up a cash reserve equal to six months of costs.
When the property market cooled two years later, orders fell by 40%. Competitors that had expanded struggled with debt, whereas Meridian used its reserve to ride out the slowdown and bought equipment at a discount from a failing rival. The story is illustrative, but it shows why caution during a boom can pay off. The owners later said the discipline felt frustrating at the time but turned out to be the best decision of the decade.
Watch out
Common mistakes.
- Treating "echo bubble" as a technical or official term. It is a descriptive phrase, and different writers use it in different ways.
- Assuming a bubble can be identified with certainty while it is happening. Only hindsight confirms whether prices were truly unjustified.
- Believing that this time is different. Bubbles tend to repeat familiar patterns of cheap credit, rising leverage and rising confidence.
Questions
People also ask.
What causes an echo bubble?
Common ingredients are low interest rates, easy credit, investors looking to recover losses and a story that makes a new asset seem special.
How is an echo bubble different from a normal bubble?
It follows closely after an earlier bust and is seen as a continuation of the same pattern, but there is no precise rule dividing the two. Analysts therefore tend to describe the link in words rather than with a number.
How can a business protect itself?
It can keep debt moderate, hold cash reserves, avoid relying on one boom market and stress test its plans for a sharp fall in demand. A prudent firm does this in good times, when funding is cheap and easy to arrange.
