New military actions by the United States and Israel in the Middle East triggered a market reaction that defied conventional safe-haven logic. On Tuesday, the U.S. dollar strengthened, gold plunged, government bond yields rose across the board, and both the Japanese yen and Swiss franc declined—traditional safe-haven assets collectively lost their defensive appeal. The only asset acting as a refuge was crude oil. Brent crude surged more than 8% intraday, becoming the most prominent winner and reshaping the performance logic of nearly all other assets that day.

This combination is highly unusual. According to The Wall Street Journal, since 1983, there have been only 16 instances where Brent crude rose more than 7% in a single day while gold fell and bond yields increased. Furthermore, during Tuesday's early trading, the S&P 500 index fell over 2%—a decline never seen in any of those previous 16 occurrences. Analysis suggests that for investors holding gold, U.S. Treasuries, and consumer staples stocks as hedges, the day's experience was far more uncomfortable than the price movements alone indicated. Market logic shifted from "stocks to bonds, weak currencies to strong" to "oil-importing nations suffer, oil-exporting nations benefit."

Bonds fell first, followed by gold, the yen, and the Swiss franc. During periods of significant global turmoil, government bonds are typically the first refuge for capital. However, on Tuesday, U.S. Treasury yields rose instead of falling, and even yields on Swiss government bonds, renowned for their safety, moved higher. The reason lies in the immediate transmission of the sharp oil price increase to inflation expectations, which dampened market bets on Federal Reserve interest rate cuts and consequently pushed bond yields higher. Under this mechanism, the safe-haven function of the bond market was directly negated.

The logical chain was clear and direct: rising oil prices → heightened inflation expectations → reduced rate cut expectations → higher bond yields → falling bond prices. Tuesday's market movements perfectly illustrated this sequence. Gold should theoretically benefit from inflation concerns, yet its price fell approximately 4% on Tuesday. Even after a strong afternoon rebound in equities, gold's decline remained significant.

Analysts noted that gold suffered a "double blow." First, gold is priced in U.S. dollars, so dollar strength directly pressured the gold price. Second, before the Middle East conflict erupted, gold had already rallied 21%, leaving it at elevated levels and making it a convenient target for traders looking to reduce leverage when needed. This phenomenon highlights a market reality: when an asset experiences excessive gains and becomes overcrowded with positions, it can become one of the first assets sold during an external shock, rather than acting as a safe haven.

Notably, while the U.S. dollar index rose about 1% on Tuesday, superficially aligning with the typical pattern of capital flowing into the dollar during crises, the underlying driver of this dollar appreciation was fundamentally different. In typical risk-off scenarios, the Swiss franc and Japanese yen tend to strengthen alongside the dollar, sometimes even outperforming it. However, on Tuesday, the Swiss franc fell 0.5% against the dollar, and the yen declined 0.3%. This suggests capital was not seeking the "safest currencies" but rather concentrating in "oil-benefiting nations."

The United States is the world's largest oil producer and a net oil exporter. If Iran disrupts tanker traffic through the Strait of Hormuz or attacks oil and gas infrastructure in the Arabian Peninsula, the U.S. would be one of the primary economic beneficiaries. Norway is in a similar position—the Norwegian krone appreciated noticeably against the dollar that day. In contrast, most European countries and Japan are net oil importers, placing pressure on their respective currencies.

Oil prices dictated everything, but the outlook remains uncertain. Rising oil prices hurt equities; falling oil prices help equities. Until the outcome of the conflict becomes clear, every fluctuation in crude will directly steer market direction. Remarkably, on Tuesday, both rising and falling scenarios played out within the same trading session. Analysts pointed out that all of Tuesday's market volatility was predicated on one assumption: the war would persist, and Iran retained the capability to significantly disrupt oil transportation or production.

However, this assumption was later challenged. A statement from former President Donald Trump indicated that the U.S. might begin providing escorts for oil tankers transiting the Strait of Hormuz. This announcement complicated market assessments of the situation's trajectory. According to reports, the market's turning point on Tuesday occurred in the afternoon following Trump's post on Truth Social, which stated:

"Effective immediately, I have directed the U.S. International Development Finance Corporation to offer political risk insurance and financial security at reasonable terms for all maritime commerce, especially energy shipments, transiting the Gulf region. If necessary, the U.S. Navy will promptly begin escorting tankers through the Strait of Hormuz. America will ensure the free flow of energy to the world."

This statement prompted a rapid reversal in market sentiment. Oil prices retreated from their highs, while equities rebounded significantly from their intraday lows. Adam Turnquist of LPL Financial noted that the latest developments helped reduce concerns about a major disruption to global supplies, easing inflation tensions and calming the surge in Treasury yields.
