Optimism over a potential peace agreement between the U.S. and Iran has restored calm to the U.S. Treasury market recently, but a growing number of Wall Street institutions are warning that this low-volatility environment may not be stable.
Recently, volatility indicators in the U.S. Treasury market have fallen to their lowest levels this year, nearly erasing the market panic previously triggered by the Middle East conflict and surging oil prices. At the same time, the yield on the 30-year U.S. Treasury note has also retreated significantly from its near 19-year high.
Earlier, tensions between the U.S. and Iran pushed up energy prices and sparked concerns about re-inflation and potential Federal Reserve rate hikes, leading to a significant sell-off in the Treasury market. However, as markets have begun betting on a possible peace agreement between the two sides, Treasury yields have gradually declined, and market sentiment has noticeably stabilized.
Nevertheless, Morgan Stanley's strategy team believes that the current market expectation of "sustained calm" may be underestimating potential future risks. Strategists including Shaun Zhou stated in a recent report that factors such as renewed shocks in energy markets and escalating geopolitical conflicts could quickly reignite volatility in long-term interest rates. The report noted, "The market has formed a clearly asymmetric situation, where relatively small macro catalysts could lead to a significant repricing of long-term interest rate uncertainty."
In fact, some large traders have already begun positioning ahead. Last week, a "long volatility" trade with a premium of up to $15 million appeared in the U.S. Treasury options market, betting on a return to sharp market fluctuations. At the same time, there has been a surge in "straddle" and "strangle" option strategy trades recently.
These strategies are typically used to bet on significant future volatility in the underlying asset without specifying a direction. Analysts point out that this indicates a growing number of funds are concerned that the current low-volatility state in the Treasury market may not be sustainable.
However, not all investors believe volatility will rise again. On Tuesday, there were also significant "short straddle" trades in the market, betting that interest rate volatility will continue to decline. This strategy means that as long as Treasury prices remain relatively stable in the future, sellers can earn premium income. However, if the market experiences sharp fluctuations again, these positions could quickly incur substantial losses.
Morgan Stanley explicitly warns that the current macro environment remains "fragile." The bank noted that multiple factors currently suppressing market volatility could weaken simultaneously in the future, and the extremely low implied volatility suggests that the market may be significantly underpricing risks.
Beyond the derivatives market, bullish sentiment has also reemerged in the spot Treasury market recently. According to the latest JPMorgan client survey, as of the week ending May 26, investors' net long positions have risen to a one-month high. Data shows that investors' long positions increased by 5 percentage points, while short positions decreased by 2 percentage points.
Meanwhile, the SOFR (Secured Overnight Financing Rate) options market has also seen a surge in new bets recently. Notably, a large number of new positions have accumulated around the 96.5 strike price, indicating that the market is actively positioning for potential future changes in interest rate paths.
Analysts point out that the core market contradiction lies in the fact that, on one hand, the easing Middle East situation has stabilized market sentiment in the short term; on the other hand, uncertainties surrounding inflation, energy prices, and the Federal Reserve's policy path are still sufficient to reignite significant volatility in the long-term Treasury market. Wall Street fears that the current market "calm" may only be a brief window before the next wave of major fluctuations.
