Since the outbreak of the Middle East conflict, traditional correlations among global assets have broken down and have yet to recover. Investors are navigating with a malfunctioning dashboard, piecing together trading strategies as they grope for clarity. The S&P 500 index has repeatedly hit record highs, starkly contrasting with severe geopolitical risks, persistent threats of energy supply disruptions, and underlying concerns about long-term economic damage.
According to Mark McCormick, Chief FX Strategist at BMO, the market is expected to depart from its pre-conflict norms over the next three to six months. He noted in a research report, "While economic growth momentum has shown some improvement, it remains below levels projected for late 2025. Pressure from tightening monetary policy persists, asset interrelationships continue to be reconfigured, and risks of asset drawdowns are rising, indicating a new market landscape is gradually taking shape."
This analysis focuses on four major asset classes—stocks, bonds, currencies, and commodities—to examine the breakdown of traditional market linkages. These relationships have historically served as a core reference for assessing economic trends.
Fixed income markets are facing a severe test. Under normal conditions, stock markets and bond yields typically move in tandem. Concerns about economic downturns lead investors to seek safety in bonds, depressing equities and yields; the opposite occurs during economic expansions. However, since the pandemic, this pattern has been persistently disrupted, as high inflation and elevated government debt continue to undermine bonds' traditional role as a hedge against equity risk.
Prior to the escalation of geopolitical tensions in February, the International Monetary Fund warned in a blog post that investors and policymakers must reconsider risk management in a "new era" where conventional hedging tools are failing. Two-year government bonds, highly sensitive to inflation and interest rate expectations, are at the epicenter of the current market turbulence. The rolling monthly correlation between the U.S. two-year Treasury yield and the S&P 500 has plummeted to approximately -0.8 from a five-year average of 0.23. Since the conflict began, this figure has stabilized around -0.63. A highly similar divergence is observed between Germany's two-year bond yield and the Europe Stoxx 600 index.
Michael Metcalfe, Global Head of Macro Strategy at State Street, remarked, "Historically, short-term sovereign bonds should have attracted inflows during the market turmoil in March, but that did not materialize. This shock presents a severe test for fixed income markets, as it represents both an inflation shock and a potential growth shock, amplifying concerns about long-term fiscal outlooks."
Gold is exhibiting反常 behavior. Following the recent geopolitical conflict, gold has shed its classic safe-haven attributes, moving in unusual lockstep with equities and highly volatile cryptocurrencies. Its current price remains about 10% below its pre-conflict peak. Traditionally, gold maintains a strong inverse correlation with the U.S. dollar. During periods of heightened market volatility, when investors sell risk assets like stocks and bonds, the dollar typically becomes the primary safe-haven choice, a pattern observed during this conflict as well. The correlation between gold and the dollar has narrowed to -0.19 from a five-year average of -0.4 since late February. Conversely, the correlation between gold and equities has risen to 0.55, significantly exceeding its five-year average of 0.22.
This may reflect an extreme anomaly in the relationship between the dollar and equities: their correlation recently dropped to -0.94, nearing perfect inverse correlation, compared to a five-year average of -0.28. Meanwhile, the correlation between Bitcoin and U.S. stocks has surged to a record high of 0.96, far above its pre-conflict average of 0.4, substantially weakening cryptocurrencies' value for portfolio diversification.
Extreme events are generating反常 market effects. Rising inflation risks have led traders to price in expectations for interest rate hikes, particularly in Europe, while expectations for U.S. rate cuts have diminished significantly. Typically, divergence in monetary policy between regions directly drives currency strength differentials, but this classic logic has also failed. Markets widely anticipate the European Central Bank will implement two rate hikes this year, whereas the Federal Reserve is inclined toward cutting rates. Nevertheless, the EUR/USD exchange rate has merely stabilized around 1.17, showing little recovery from its post-conflict decline.
UniCredit stated, "Major disruptive events can reshape financial market dynamics, overturning traditional relationships between various assets and economic indicators. The decoupling of the EUR/USD exchange rate from interest rate differentials is a clear example." Measured by the two-year swap rate spread between the U.S. and Europe, the correlation between the interest rate differential and the euro's exchange rate has risen to 0.5. This figure was nearly zero at the start of the year and averaged -0.3 over the past two years. UniCredit added, "Until the risk premium induced by the geopolitical conflict fully dissipates, the Europe-U.S. rate differential is unlikely to re-emerge as the dominant factor for the euro."
Inflation expectations are becoming unanchored from fundamentals. Historically, rising oil prices directly push up market inflation expectations. However, despite a significant oil price surge during this conflict, long-term inflation expectations have continued to decline. The five-year, five-year forward inflation swap rate, a gauge of U.S. long-term inflation expectations, has fallen to around 2.4% from approximately 2.45% previously, even as oil prices have maintained a cumulative gain of about 40%. The correlation between the two has dropped to -0.7, a significant deviation from its five-year average of 0.2. In contrast, during the 2022 energy crisis triggered by the Russia-Ukraine conflict, this indicator rose to 0.7.
Analysis from Deutsche Bank suggests that increased U.S. fiscal spending related to the conflict and widening fiscal deficits are partial contributors to this reversal in inflation logic. "But another possibility is that the pricing of forward inflation is becoming increasingly disconnected from fundamentals," the bank noted.
