A crisis-level print that vanished in weeks
On August 5, 2024, the VIX briefly spiked intraday to around 65 — its highest intraday level since the March 2020 COVID crash — before settling to close near 38. For a few hours the fear gauge flashed a reading associated with genuine crisis. Yet within weeks it had reverted toward its normal range, making August 2024 a textbook study in the difference between a positioning shock and a systemic one.
The episode is also a lesson in how the VIX is calculated. The eye-catching intraday figure near 65 was distorted by thin liquidity in the S&P 500 options used to compute the index before the U.S. cash open; VIX futures, traded by professionals, never priced in anything close to that level. This page covers the catalysts, the data, and why the spike faded. It is educational information, not investment advice.
Two catalysts in a single week
August 2024 was not one shock but two, landing within days of each other and reinforcing one another.
Late July to early August 2024
- July 31, 2024 (Bank of Japan hike): The BoJ raised its policy rate and signaled further tightening. A higher yen undercut the long-standing carry trade — borrowing cheaply in yen to buy higher-yielding assets elsewhere.
- August 1–2, 2024 (weak U.S. jobs data): A soft U.S. employment report stoked recession fears and triggered closely watched recession signals, adding a growth scare to the currency shock.
- August 5, 2024 (the unwind): Japanese equities fell sharply overnight and global risk assets sold off as leveraged carry positions were unwound. The VIX gapped higher, touching roughly 65 intraday before closing near 38.
- Mid-to-late August 2024: As the deleveraging passed and U.S. data steadied, the VIX mean-reverted back toward normal levels.
The carry-trade unwind is the heart of the story: when the funding currency (the yen) strengthens abruptly, leveraged positions financed in that currency must be cut all at once, forcing simultaneous selling across markets.
The numbers, in context
| Measure | August 2024 | Note |
|---|---|---|
| Prior-day VIX close | ~23 | Already elevated heading in |
| Aug 5 intraday high | ~65 | Highest intraday since March 2020; thin pre-open SPX options |
| Aug 5 close | ~38 | Far below the intraday spike |
| VIX futures | well below spot | Never priced the ~65 print; deep backwardation |
The gap between the ~65 intraday spot reading and a much lower futures market is the key data point. It tells you the headline number overstated the actual fear that professionals were willing to pay for. For why the spot index can behave this way, see VIX term structure and why is the VIX low for the calm regime it sprang from.
Why it reverted so quickly
August 2024 shares its essential shape with Volmageddon: a sharp, mechanical, positioning-driven spike rather than a deep macro crisis. The distinction explains the speed of the recovery.
Anatomy of a fast-fading spike
- Forced, finite selling. Carry-trade deleveraging is intense but self-limiting — once the leveraged positions are cut, the pressure stops.
- No systemic breakage. Unlike 2008, there was no credit freeze or banking failure underneath the move.
- Steep backwardation. The futures curve inverted hard, signaling the market expected volatility to subside — and it did.
- Mean reversion in action. The VIX's tendency to revert toward its baseline reasserted itself within weeks, a pattern explored in VIX mean reversion.
This is educational framing, not a recommendation. The structural lesson is that a liquidity-and-positioning shock can produce a crisis-level print without producing a crisis-level regime.
Reading the spot-versus-futures gap
The August 5 episode is one of the clearest real-world demonstrations of why the spot VIX and VIX futures can diverge sharply, and why a savvy reader checks both. The spot VIX is computed continuously from a strip of S&P 500 option prices. Before the U.S. cash equity market opens, those options are thinly traded; a handful of wide quotes on deep out-of-the-money puts can drag the calculation to an extreme that no large position could actually transact at.
Why the ~65 print overstated the fear
- Thin quotes feed the formula. The VIX calculation is only as reliable as the option prices behind it; pre-open, those prices are sparse and skewed.
- Futures price what traders will pay. VIX futures, set by participants posting real risk capital, never approached 65 — a far more honest read of expected volatility.
- The close told the truth. By the time liquidity normalized, the index closed near 38, roughly 27 points below its intraday extreme.
The practical lesson: treat a sensational intraday spot reading with skepticism when liquidity is poor, and corroborate it against the futures curve. This is exactly the kind of nuance covered in how to read the VIX and in our breakdown of how the VIX is calculated.
Anatomy of a carry trade unwind
To understand why a Bank of Japan rate decision could jolt the U.S. fear gauge, it helps to understand the mechanics of the carry trade. For years, investors borrowed in yen at near-zero rates and deployed the proceeds into higher-yielding assets — U.S. equities, emerging-market debt, the dollar, and more. The strategy earns the interest-rate differential as long as the yen stays weak and stable.
- The funding currency strengthens. When the BoJ hiked and signaled more tightening, the yen rallied, eroding the very edge the carry trade depended on.
- Margin pressure builds. A rising yen increases the cost of repaying yen-denominated loans, pressuring leveraged positions.
- Positions are cut simultaneously. Because the trade was crowded and leveraged, the exits happened all at once, forcing sales across otherwise unrelated assets.
- Volatility spikes globally. Correlated selling and a growth scare from the weak U.S. jobs print pushed the VIX sharply higher.
It is the same crowding-plus-leverage pattern that recurs across these case studies — the funding source differs, but the unwind dynamic rhymes with both Volmageddon and the deleveraging phases of larger crises.
How August 2024 fits the record
Placed alongside the other major events, August 2024 belongs to the "fast and mechanical" family rather than the "deep and durable" one. Its intraday print rivaled crisis levels, but its closing value and its short duration tell the real story.
- Versus 2020: The COVID-19 crash closed at 82.69 and stayed elevated for months; August 2024 closed near 38 and faded in weeks.
- Versus 2018: Like Volmageddon, the move was amplified by positioning and liquidity, then unwound quickly.

Frequently asked questions
How high did the VIX spike in August 2024?
On August 5, 2024 the VIX briefly spiked intraday to roughly 65 — its highest intraday level since the March 2020 COVID crash — before settling to close around 38. The intraday figure was inflated by thin pre-open liquidity in the S&P 500 options used to calculate the index.
What caused the August 2024 VIX spike?
Two catalysts collided: the unwind of the Japanese yen carry trade after the Bank of Japan raised rates on July 31, 2024, and a weak U.S. jobs report on August 2 that sparked recession fears. Both hit over a few days, forcing a rapid global de-risking.
Why did the August 2024 spike fade so fast?
It was a positioning and liquidity shock, not a systemic crisis. Once the carry-trade deleveraging passed and U.S. data steadied, the VIX mean-reverted toward normal levels within a few weeks rather than staying elevated for months.
