  • Options traders’ crash fears near pre-strike levels
  • TailDex and Cboe Skew Indexes show reduced crash protection costs
  • Market anxiety remains higher than early February levels

NEW YORK, March 17 (Reuters) – Options traders’ fears of a U.S. stock market crash have pulled ‌back nearly to levels seen before the U.S.-Israeli attacks on Iran that made oil prices soar.

, two separate gauges that measure how much traders are paying ​for crash protection, have retreated to near where they stood before the ​February 28 strikes on Iran. The S&P 500 is still down ⁠2% from pre-war levels.

“TDEX is signaling that investors are now less worried about a “tail ​event,” or a really steep drop in equity prices, than at any point since ​the war started,” said Scott Nations, president of Nations Indexes, an independent developer of volatility and option strategy index products.

“Given the muted response from the S&P 500, this outlook makes sense, but ​it’s an important metric to watch,” he said.

On Monday, the TailDex index was at ​18.84, just below its closing level of 19.01 on February 27. The Cboe SKEW index finished ‌at ⁠141.49 on Monday, down from 146.67 prior to the air strikes.

Both indexes soared to multi-month highs as soaring oil prices unleashed fear of a sizeable pullback in markets.

The cost of deep out-of-the-money S&P 500 puts – contracts that would offer protection against a ​20% drop in the ​market over the ⁠next three months – stands just slightly higher than it was immediately prior to the strikes, according to Susquehanna Financial Group strategist ​Christopher Jacobson.

“After hitting multi-year highs at times last week, S&P skew ​levels have ⁠declined incrementally as some of that downside tail bid has faded alongside,” Jacobson said.

While fear of a market crash has faded, market anxiety levels are still higher than they ⁠were ​in early February. Nor are investors rushing to bet ​on a sharp rebound in stocks past old highs.

“We haven’t really seen that skew shift back towards the ​upside tail,” Jacobson said.
