AI Chip Boom Lifts Tech; Oil Shock Roils Bonds Ahead of US Open

Overnight sessions painted a stark tale of two markets: euphoria in semiconductors, anxiety in durationBond price sensitivity to interest rate changes.. Asia and Europe closed with a resounding cheer for AI infrastructure plays after the US approved NVIDIA H200 chip sales to ten Chinese companies on May 14, a move coinciding with CEO Jensen Huang's visit to Beijing during the Trump-Xi summit. The approval signals an easing of US-China tech restrictions and validates the broadening AI capex narrative. Cerebras Systems, an AI chipmaker specialist, raised $5.55 billion in an upsized IPOInitial Public Offering - a company's first public sale of stock. and is indicated to open 89% above its $24 listing price, marking the year's largest tech IPO. The combined effect lifted NVIDIA to within striking distance of $6 trillion in market value after a 20% rally in seven days, while Broadcom (AVGO) and AMD also benefited from the supercycle conviction.

Simultaneously, however, global bond markets entered a historically violent repricing. The Iran conflict and resulting Strait of Hormuz disruption have upended oil supply, with WTI and Brent crude rallying on 20% of global flows blocked. Treasury yields, gilts, and JGBs have all hit multi-year highs as inflationThe rate at which prices rise across an economy. expectations shift sharply higher. T. Rowe Price CIO Sebastian Page warned of a "collision course between inflation and Fed policy," while RBC strategist Lori Calvasina flagged that a 5% 10-year Treasury yield would challenge equity bull arguments and compress price-to-earnings multiples. The selloff has been global and acute, with the British pound posting its worst week since 2024.

US index futures are set to open with upward bias from the AI narrative, but face headwinds from the bond sell-off and rising real rates. The S&P 500 has added 38% of its market cap to just seven mega-cap names (NVDA, MSFT, GOOGL, META, AMZN, AAPL, TSLA), creating concentration risk that could amplify volatility if rotation sentiment shifts. Broadening participation remains weak; breadth metrics suggest the rally is narrowing. Mega-cap tech wealth effects may sustain near-term momentumThe empirical fact that winners keep winning over the medium term., but the tone in rates, credit spreads, and volatility is fragile. Watch for any intraday reversal if bond yields push past technical resistance.

The macro calendar for May 15 appears light in terms of scheduled releases; however, the Trump-Xi summit backdrop and ongoing Iran supply shock will dominate real-time price discovery. Oil markets are the chief risk asset, with energy stocks benefiting but broader equity valuation compression a growing threat. Gold and the US dollar have both rallied on flight-to-safety flows and higher real rates. Crypto has been a bright spot; Bitcoin rallied to $81k and XRP surged 8.6% after the Senate Banking Committee advanced the CLARITY Act on May 14, defining regulatory jurisdiction over crypto assets and settling the SEC-CFTC turf war.

Earnings flow remains light before the open. The equity positioning narrative is dominated by AI capex exuberance, yet rate volatility, oil shocks, and concentration risk create a tactical minefield. The desk is leaning long tech but watching for any deterioration in bonds or equity breadth. Any move above 5% in the 10-year will test conviction; any move above $85 WTI will signal deeper inflationThe rate at which prices rise across an economy. concerns. Sector rotation risk is high.

Key levels: S&P 500 near fresh highs but breadth diverging; Nasdaq near records on mega-cap concentration; Russell 2000 lagging sharply as small caps struggle with rising rates. The 10-year Treasury is the day's pivot; break above 4.8% on a sustained basis could trigger de-risking and profit-taking in AI names. Watch Goldman Sachs, JPMorgan, and other rate-sensitive financials for signals of capitulation or conviction in the current setup.
