Boeing (BA) kicked off the Farnborough International Airshow with a triple-digit aircraft commitment Monday, while on the other side of the globe South Korea’s roller-coaster equity market is watching individual investors pull back sharply. SMBC Aviation Capital signed for 100 737 MAX jets—60 of the stretched 737-10 variant and 40 737-8s—handing the U.S. manufacturer an early commercial victory at the industry’s marquee trade event. The same day, Korean brokerage data showed retail trading deposits had slumped roughly ₩24 trillion ($16.3 billion) so far in July as whipsawing indexes, a central bank rate hike and tighter mortgage rules sap the ammunition of the country’s army of day traders.

The twin developments underscore how a single session can capture diverging moods: Western aerospace executives are betting on a multi-year upswing in global travel, while Asian retail investors are retreating to the sidelines after a brutal stretch of circuit breakers and sidecar halts.

Farnborough Opens with a Leasing-Giant Endorsement

SMBC Aviation Capital, already the world’s second-largest aircraft lessor after completing its acquisition of Air Lease earlier this year, described the deal as its first-ever purchase of the 737-10, the highest-capacity member of the MAX family. The Dublin-based platform—backed by Sumitomo Mitsui Financial Group and Sumitomo Corporation—now counts 450 owned, managed and committed 737 MAX jets.

“This transaction represents a significant milestone for SMBC Aviation Capital and will ensure our airline customers have access to a long-term pipeline of new technology aircraft,” Chief Executive Peter Barrett said in a statement. “Our partnership with Boeing spans over two decades and this order reflects market dynamics as our airline and investor customers look to upgauge to the 737-10.”

Neither side disclosed the financial value or delivery timetable, though the commitment is the largest single 737-10 order ever placed by a lessor. Boeing Commercial Airplanes President and CEO Stephanie Pope called the deal a reflection of “the strong demand we are seeing for the 737 MAX family’s efficiency, reliability and versatility.”

Aircraft lessors have become critical customers for both Boeing and Airbus (EADSY) because they allow airlines to refresh fleets without tying up capital in outright purchases. Single-aisle models such as the 737 and the A320 family are the most liquid assets in the jet-finance industry, making them attractive to investors who back leasing platforms.

Boeing also disclosed that Saudi Arabia’s Riyadh Air is exercising options for 28 787 Dreamliners from a 2023 order and will convert 20 options to the largest Dreamliner variant. Airbus separately said Riyadh Air had firmed an order for six additional A350-1000s, bringing its total commitment for the type to 31 aircraft.

Seoul’s Retail Army Runs Low on Ammo

While Farnborough celebrated dealmaking, Seoul’s dealing rooms were digesting another bout of turbulence. The benchmark KOSPI index closed 4.46 percent lower Monday, extending a stretch that has already triggered two market-wide circuit breakers, six sell-side sidecars and three buy-side sidecars this month alone.

Investor deposits—cash parked in brokerage accounts ready to buy stocks—stood at ₩108.08 trillion ($73.2 billion) as of July 16, according to the Korea Financial Investment Association. That is down roughly ₩24 trillion from ₩132.47 trillion at the end of June, an 18.4 percent drop in just over two weeks. The balance had brushed against ₩140 trillion in early June when the KOSPI briefly traded above the 8,000 level.

“In a market where sidecars and circuit breakers are being triggered about once a week, it is hard to expect large-scale inflows based solely on fundamental improvement,” said Lee Jae-won, an analyst at Yuanta Securities. “Retail investors are supporting the market, but considering the Bank of Korea’s rate hike, government loan regulations and falling deposits, individual buying power cannot expand indefinitely.”

The Bank of Korea lifted its benchmark rate for the first time in three and a half years this half, and signaled further tightening could follow. Commercial banks have simultaneously tightened household lending, squeezing the leverage that many retail traders have relied on.

Exchange-traded fund flows reflect the shift toward safety. Over the past week, the “KODEX 200 Target Weekly Covered Call” ETF pulled in ₩141.1 billion ($95.6 million), while money-market ETFs such as “1Q Money Market Active” and “RISE Money Market Active” also ranked among the top 20 for inflows, according to Koscom ETF Check.

A reverse money-move is also visible in banking data. Deposit balances at Korean banks rose ₩28.8 trillion month-on-month in June to ₩2,622.5 trillion, while loan balances increased by a smaller ₩12.7 trillion. Earlier in the year the gap had been narrowing as cash rushed into equities; that trend has now reversed.

Not Everyone Is Calling It an Exodus

Some analysts caution against reading the deposit decline as a wholesale exit from stocks. Kim Jae-seung of Hyundai Motor Securities argued that the drop is a consequence rather than a cause. “The fall in customer deposits can be seen as a reduction in additional buying capacity, but it is premature to interpret it as individual investors leaving the domestic market or as a signal of deteriorating retail supply-demand dynamics,” he wrote.

Kim noted that heavy retail buying had been concentrated between the 7,000 and 8,500 levels on the KOSPI, meaning much of the cash that has vanished from deposit accounts is now simply tied up in equity positions. “Rather than a loss of investment capacity, we should pay attention to potential selling pressure when the market rebounds,” he added.

What It Means for Markets

For Boeing, the SMBC order reinforces the narrative that the 737 MAX program has put its quality and regulatory troubles behind it. The Federal Aviation Administration lifted the production cap on the single-aisle jet in October 2025, and the company is now awaiting certification of three new aircraft variants after years of delays. A large lessor willing to bet on the largest MAX variant signals confidence that airlines will need bigger narrow-bodies for high-density routes well into the 2030s.

For South Korean policymakers, the rapid evaporation of retail deposits is a warning that the army of individual investors who helped power the KOSPI’s surge past 8,000 may not have limitless firepower. If the Bank of Korea continues tightening and volatility persists, the deposit base could shrink further, potentially removing a key pillar of support that has cushioned the market during sell-offs. The coming weeks will test whether the cash is merely parked in stocks—ready to be sold on any bounce—or whether it has genuinely left the building.
