Summary

The episode focuses on the convergence of elevated US Treasury yields, oil above $100, and a heated AI safety debate that hit semiconductor shares. Guests debate whether the AI selloff is a knee-jerk reaction or a real slowdown risk, while discussing rotation into software, cybersecurity, Asia value sectors, energy, JGBs, and risks around SoftBank and Kioxia. Central bank meetings, especially the Fed and BOJ, are a key backdrop.

  • US 10-year yield briefly tops 5%, pressuring equities and raising inflation concerns.
  • AI safety warnings and political pushback hit chipmakers; the Philadelphia Semiconductor Index falls.
  • Oil stays above $100 as Saudi pipeline outages and Strait of Hormuz risks constrain supply.
  • Speakers debate AI demand resilience, favoring software and cybersecurity over AI semis.
  • Asia value sectors, pharmaceuticals, energy and JGBs are highlighted as selective opportunities.
  • SoftBank is flagged as vulnerable to OpenAI IPO delay and BOJ rate hikes.
  • Fed and BOJ meetings, bond auctions, China credit data, and Hong Kong's five-year plan are in focus.
Ideas
Mark Cranfield Cross Asset Strategist, Bloomberg 3:06
Bonds no longer hedge equity risk
Government bonds are no longer acting as a reliable equity hedge; the typical hedge relationship has broken down during geopolitical conflict and is breaking down again, leaving multi-asset portfolios without the expected ballast.
Mark Cranfield Cross Asset Strategist, Bloomberg 4:17
Japanese tech may underperform Asia
Kioxia's potential large U.S. fundraising would take capital out of an already declining market, while hyperscaler spending concerns weigh further; Japanese tech stocks may underperform the rest of Asia.
Dilin Wu Head of Research, The Block 19:17
Cautious AI pace helps incumbents
The AI slowdown debate is not an immediate shock to the AI cycle; if development is paced more cautiously, it reduces competitive pressure and aggressive capex commitments, which is positive for the biggest AI incumbents even if the initial market reaction is risk-off.
Dilin Wu Head of Research, The Block 20:04
Oil and BOJ pressure Nikkei
Japan is a major energy importer, so oil above $100 hurts its economy and Nikkei upside; the BOJ hike is priced, but the combination of energy costs and BOJ policy creates a negative overhang for the Nikkei 225.
Dilin Wu Head of Research, The Block 21:33
BOJ hiking path supports yen
If the Bank of Japan signals a continuous rate-hiking path rather than a one-off move, that could marginally support the yen as forward guidance becomes more hawkish.
Lynn Managing Editor, Bloomberg 28:52
AI computing demand remains resilient
The knee-jerk AI selloff is overdone because demand for AI computing remains intact and resilient, with much usage coming from already established in-service AI systems rather than only training new models; tapping the brakes on new development does not eliminate that demand.
Anthony Stevens Bloomberg Market Producer 33:39
Software and cybersecurity benefit from AI
Existing falls in token prices and open-weight models are benefiting AI users; software and cybersecurity rally as users monetize deployed AI, and cybersecurity CEOs highlight AI risk, making software and cybersecurity relative winners in the AI disruption.
Anthony Stevens Bloomberg Market Producer 34:14
China India software beat semis
A divergence may emerge where software plays in China and India outperform semiconductors as high yields and political uncertainty challenge the AI semiconductor trade.

China India software beat semis
A divergence may emerge where software plays in China and India outperform semiconductors as high yields and political uncertainty challenge the AI semiconductor trade.
Anthony Stevens Bloomberg Market Producer 34:47
Asia ex-Korea value rotation
With high yields and AI uncertainty, Asia ex-Korea and Taiwan offers value sectors such as financials, energy, metals and pharmaceuticals that screen well as a rotation away from the momentum AI trade.
Anthony Stevens Bloomberg Market Producer 35:05
Pharma and biotech value rotation
Pharmaceuticals are a structural loser of AI in product development but offer value, cash-flow richness and a different flavor from momentum AI; they screen well and the Hang Seng Biotech Index is a way to play the rotation.
Alice French Japan Equities Reporter, Bloomberg 43:51
Kioxia ADR positive but valuation risky
Kioxia's planned U.S. ADR listing is positive for liquidity and valuation and signals confidence in chip demand, but the stock has rallied over 350% this year and higher borrowing costs create tail risk for the shares.
Alice French Japan Equities Reporter, Bloomberg 44:53
Japanese AI supply chain demand resilient
Japan's AI trade is broad and includes many chip and gear makers supplying necessary parts; even a slight slowdown in AI development should not reduce demand for these parts unless supply and demand loosen considerably, so the rally need not slow.
Mark Franklin Deputy Head of Asia Multi-Asset, Manulife 52:11
Energy prices to spike further
Middle East conflict, the closed Saudi East-West pipeline and risks around the Strait of Hormuz are constraining supply while inventories are low; unless conflicts stop, expect ongoing volatility and attempted spikes to further breakout in upstream and downstream energy prices.
Mark Franklin Deputy Head of Asia Multi-Asset, Manulife 60:02
JGB yields attractive to investors
With 10-year JGB yields around 3%, foreign investors get favorable yield levels and hedging differentials while domestic investors see improving relative yields; although valuation is creeping in, the JGB market is becoming more interesting.
Anthony Stevens Bloomberg Market Producer 66:39
Korea Taiwan AI case positive
Much AI spending is long-lead data-center construction into 2027-28, so the medium and short-term impact on Korea and Taiwan economies and chip exports is limited; their baseline AI economic case remains positive for the next couple of years even if frontier 2028-29 spending is challenged.
Shuli Ren Opinion Columnist, Bloomberg 68:16
SoftBank faces refinancing and carry unwind
OpenAI's delayed IPO is badly timed for SoftBank because Masayoshi Son financed a $65bn OpenAI stake with borrowed money and must refinance; SoftBank lacks recurring cash flow to cover interest, and BOJ rate hikes reverse its cheap-yen carry trade, making the risk profile severe.
Yasutaka Asian Equity Reporter, Bloomberg 93:17
Samsung ADR seeks US valuation
U.S. semiconductor valuations are much higher than Asian markets, so Samsung is considering a U.S. ADR listing to access a broader U.S. investor base and capture a higher valuation.
