Markets were moderately risk-on: 11 of the 12 equity markets tracked rose, credit gained modestly and the dollar weakened. The rally was broad but uneven, led by South Korea and semiconductors, while China fell sharply; stronger gold, energy and weak long-dated US Treasuries added an inflation-sensitive undertone.
TOP THEMES THIS WEEK
- AI investment is becoming a credit story
Nvidia and major financial institutions are developing a financing pipeline of up to $500 billion for AI infrastructure, while chipmakers are increasingly supporting loans secured against their products. This expands the AI build-out but introduces contingent liabilities and collateral risks that may only become visible when demand slows or technology becomes obsolete.
- AI market concentration is increasing volatility
Leveraged funds have channelled growing amounts of capital into a small group of AI-related companies, particularly South Korean memory-chip producers, even as investors question whether the memory cycle is approaching a peak. The week’s strong gains in South Korea and semiconductors show that the trade retains momentum, but crowded positioning could amplify any reversal.
- China is mobilising capital while managing domestic risks
Beijing is accelerating technology listings and providing strategic industries with comparatively cheap funding, while investors rotate from infrastructure names towards profitable internet platforms. At the same time, uncertainty over expiring commercial-property land leases remains a systemic concern; the 4.04% weekly fall in Chinese equities suggests that these risks are outweighing the broader rally for now. However, the mainland focused market remains well supported, falling 0.98% for the week.

- Credit strains are emerging beneath stable public markets
Defaults and borrower watchlists at major private-credit funds have risen to their highest levels in several years, despite relatively calm public credit markets this week. This divergence matters because private credit may be giving an earlier warning about weakening corporate balance sheets, particularly among highly leveraged software companies exposed to AI disruption.
