Global markets are experiencing significant turbulence this morning, with risk assets showing mixed signals. Bitcoin has climbed to $69,415.60, up 7.41% over the past 24 hours, while Ethereum has jumped 18.06% to $2,259.59, according to the latest trading data. The sharp crypto rally has triggered widespread liquidations, with Coinglass reporting 175,007 traders forced out of positions in the last day, predominantly short sellers caught off guard by the upward surge.

Meanwhile, precious metals are shining brightly, with spot gold advancing 4.27% to $4,519.35 per ounce and spot silver rising 5.07% to $66.51 per ounce. In the bond market, the US Treasury's announcement that it will "at least double" its weekly long-term debt buyback program has driven the 10-year yield down nearly 7 basis points to 4.641%, while the 30-year yield plunged almost 10 basis points to 5.189%. The dollar index, which measures the greenback against six major currencies, fell 0.83% to settle at 98.833.

The latest Federal Reserve meeting minutes revealed that several officials favored rate hikes last month, with many policymakers indicating that tighter monetary policy would be necessary if inflation fails to decline. However, the minutes from the July 28-29 meeting showed that uncertainty still keeps Fed officials highly vigilant. Participants reiterated that their interpretation of fresh data will be a crucial component of policy discussions going forward. Dallas Fed President Lorie Logan, Cleveland Fed President Beth Hammack, and Minneapolis Fed President Neel Kashkari dissented, advocating for a 25-basis-point increase. Kansas City Fed President Jeff Schmid and St. Louis Fed President Alberto Musalem, who lacked voting rights in July, indicated they would have supported a hike had they been able to vote.

In the Middle East, Israeli forces have launched an airstrike on the Gaza City police headquarters, resulting in 9 deaths and 15 injuries, according to Palestinian sources. The Israeli military has also conducted operations across the West Bank and Jerusalem, detaining at least 31 Palestinians, including Ashraf Al-Awar, the Palestinian Authority's Minister for Jerusalem Affairs. The Palestinian Authority condemned the arrest as the latest in a series of restrictive measures against its officials in Jerusalem, while the Israeli military has yet to respond to the allegations.

US officials have confirmed that American forces have quietly established a shipping corridor through the Strait of Hormuz, ensuring that millions of barrels of oil can transit the critical waterway daily. The operation, which has been running for several weeks, now sees 15 to 20 tankers per day navigating a southern route off the Omani coast. Daily oil shipments have surged to nearly 10 million barrels, with some nights seeing total volumes between 15 and 20 million barrels. While exports remain below pre-war levels, the corridor is already having a noticeable impact on global supply.

President Donald Trump has declared he is imposing the "most severe economic action ever taken against any country" on Iran, stating that Tehran failed to seize an opportunity for a deal. In a post on his Truth Social platform, Trump described this as an unprecedented "economic war and economic isolation" campaign. He warned that any nation allowing its financial institutions, businesses, airports, or government entities to support Iran would face "massive economic consequences." The President demanded an immediate halt to oil smuggling, currency swaps, cash transfers, ship registrations, and the use of shell companies, urging US allies to join Washington in isolating Tehran. Trump reiterated that Iran will never possess nuclear weapons.

Turning to the Chinese A-share market, all three major indices fell sharply on August 19, with stock index futures closing uniformly lower. The CSI 300 futures contract dropped 2.38%, the SSE 50 futures fell 1.42%, the CSI 500 futures declined 3.78%, and the CSI 1000 futures plunged 4.26%. The divergence between large-cap and small-cap stocks was striking, as the small and mid-cap growth-oriented indices suffered significantly larger losses than their large-cap blue-chip counterparts.

Analysts attribute the sharp correction primarily to external risk shocks and profit-taking. Jia Tingting, an equity index futures analyst at Shenyin & Wanguo Futures, noted that the Tuesday selloff in US semiconductor, memory, and optical module sectors cooled expectations for the global AI supply chain, transmitting risk-averse sentiment to the A-share market. Domestically, high-volatility growth sectors like semiconductors, CPO, and robotics led the decline, while defensive low-valuation sectors such as banking and coal held up relatively well.

Liao Chenyue, a financial futures derivatives analyst at Nanhua Futures, pointed to escalating Middle East geopolitical risks pushing oil prices higher, which in turn fuels global inflation expectations. Simultaneously, rising long-term government bond yields in multiple overseas countries have lifted risk-free rates, pressuring global equity valuations. These dual headwinds have collectively dampened global risk appetite and dragged the A-share market lower.

On the domestic front, Liao noted that certain sectors had accumulated substantial profits, and with external headwinds intensifying, concentrated profit-taking by market participants amplified the index correction. Jia added that with the interim earnings reporting window in full swing, uncertainty around some sectors' performance has heightened market anxiety.

Looking ahead, analysts recommend closely monitoring four key variables. First, the Middle East situation will directly determine crude oil price trends; an expanded conflict would push prices higher, raising imported inflation risks and continuing to pressure global risk assets, while de-escalation could restore market confidence. Second, shifts in Fed rate expectations and Treasury yield movements are critical for global liquidity conditions and growth-stock valuations. Liao believes that if oil-driven inflation expectations rise, rate hike bets may resurface, extending the period of elevated Treasury yields and warranting close attention to US inflation data.

Third, the release of A-share interim earnings will be pivotal for sector rotation, as investors assess the fundamental resilience of growth sectors and identify quality opportunities. Fourth, the pace of domestic pro-stabilization policy implementation and high-frequency economic data will shape market direction. Jia observed that the SSE 50 and CSI 300 focus on low-valuation heavyweight sectors like financials and consumer staples, offering strong defensive characteristics with limited downside and steady performance. In contrast, the CSI 500 and CSI 1000 comprise small and mid-cap growth names with higher trading elasticity but more pronounced short-term adjustment pressure.

Liao expects market style to gradually shift toward large-cap stocks. From both valuation and liquidity perspectives, the earlier rebound rally saw small and mid-cap indices outperform, but their valuation advantages have largely been consumed, reducing their margin of safety. If inflation rebounds and overseas liquidity expectations tighten, higher-valuation small and mid-cap indices would face greater pressure. The CSI 300 and SSE 50, with their stronger dividend and defensive attributes, are better positioned to withstand risk-off sentiment.
