The US 10-year Treasury yield rose to 4.81 per cent on Wednesday, moving closer to the 5 per cent level that Wood considers a potential trigger point for a major equity-market correction.

Rising global bond yields, US fiscal deterioration and AI-led debt issuance create fresh risks for equities

Global bond markets are increasingly becoming a key source of concern for equity investors, with Christopher Wood, global head of equity strategy at Jefferies, warning that a move in the US 10-year Treasury yield above 5 per cent could become an important trigger for a significant correction in global stock markets.

Wood, in his weekly GREED & fear note, identified rising Treasury yields as the most important near-term risk for equities. His warning comes as long-term government bond yields in the US, Japan and the UK have moved sharply higher, raising concerns over fiscal sustainability, inflation, debt issuance and the availability of global investment capital.

The US 10-year Treasury yield rose to 4.81 per cent on Wednesday, moving closer to the 5 per cent level that Wood considers a potential trigger point for a major equity-market correction.

At the same time, the US two-year Treasury yield climbed 5 basis points to 4.41 per cent, indicating that both short- and long-duration borrowing costs remain elevated.

US 10-year yield moves closer to the critical 5% threshold

The US 10-year Treasury yield has increased significantly from around 3.8 per cent on February 27, 2026, reaching 4.81 per cent.

The move is significant because the 10-year Treasury is one of the most important reference rates in the global financial system.

It influences the pricing of corporate debt, mortgages, infrastructure financing, equity valuations and several other financial assets.

A further move above 5 per cent could therefore have consequences extending well beyond the US bond market.

Investors would potentially need to reassess the return they demand from equities, credit and emerging-market assets.

Why 5% could become a major equity trigger

The 5 per cent level is important because it could represent a meaningful change in the relative attractiveness of bonds versus equities.

When long-term government bonds offer higher yields, investors can demand greater compensation for holding riskier assets.

This can place pressure on equity valuation multiples, particularly for companies trading at elevated price-to-earnings ratios.

High-growth businesses can be especially vulnerable because their valuations often depend on earnings expected several years into the future.

As the discount rate increases, the present value of those future earnings falls.

Foreign investors could reassess US assets

Wood also highlighted the potential behaviour of foreign investors.

Global investors have remained heavily invested in US equities, supported in part by the strong performance of the artificial intelligence theme.

However, the Treasury market has experienced a prolonged period of weakness.

Wood's concern is that investors who are prepared to reduce exposure to US government bonds could eventually reassess their exposure to other US assets as well.

If foreign investors simultaneously reduce holdings of Treasuries and equities, market volatility could rise substantially.

AI boom creates enormous financing requirements

The rapid expansion of artificial intelligence infrastructure is adding another dimension to the bond-market risk.

Companies are spending enormous amounts on:

Data centres
AI computing infrastructure
Semiconductor capacity
Power generation
Electricity transmission
Cooling systems
Networking infrastructure

Much of this investment requires significant capital.

According to Nigel Green, CEO of deVere Group, US corporate debt issuance linked to data-centre expansion has reached the hundreds of billions of dollars.

This creates additional competition for investor capital at a time when governments themselves are issuing large quantities of debt.

Government and corporate borrowers compete for the same capital

The increasing financing requirements of governments and companies could become an important structural factor for bond markets.

Both public and private borrowers depend on institutional investors, pension funds, insurers, asset managers and other large pools of capital.

If the supply of bonds rises faster than demand, issuers may need to offer higher yields to attract investors.

Higher yields then increase borrowing costs, potentially creating further pressure on government finances and corporate balance sheets.

This dynamic is particularly important as AI infrastructure investment accelerates.

US fiscal deterioration adds to long-term yield pressure

Wood has also pointed towards the deterioration in US fiscal conditions as a key factor behind higher long-term Treasury yields.

Persistent fiscal deficits require governments to issue additional debt.

The greater the amount of debt that needs to be absorbed by the market, the more important investor demand becomes.

If investors demand greater compensation for holding long-duration government debt, Treasury yields can rise.

This could create a challenging environment for both the bond and equity markets.

Nominal GDP growth remains an important variable

Wood also highlighted the relationship between nominal GDP growth and the 10-year Treasury yield.

US nominal GDP growth has been running at a trend rate of approximately 5.9 per cent year-on-year over the past 12 quarters, according to the note.

Wood believes that when nominal GDP growth remains significantly above the 10-year Treasury yield, there is a fundamental argument for long-term yields to move higher.

This suggests that even if inflation moderates, strong nominal economic growth could keep upward pressure on long-duration bond yields.

Global bond markets show signs of broader stress

The bond-market pressure is not confined to the US.

Government bond yields have risen sharply across several developed economies.

The 10-year Japanese government bond yield reached 3 per cent, marking its highest level since 1996.

In the UK, the 30-year government bond yield reached its highest level since 1998.

Meanwhile, the US 10-year Treasury yield has climbed to levels last seen in January 2025.

The simultaneous rise in long-term yields across major economies indicates that investors are reassessing the global interest-rate and fiscal environment.

Japan's rising yields could have global implications

The move in Japanese government bond yields deserves particular attention.

Japan has historically been associated with exceptionally low interest rates and yields.

A 10-year government bond yield of 3 per cent therefore represents a substantial change in the country's financial environment.

Japanese institutional investors are significant participants in global capital markets. If domestic bond yields become more attractive, Japanese investors could potentially reconsider overseas investments.

Any resulting repatriation of capital could affect global bond and equity markets.

UK long-term yields also send a warning signal

The rise in UK long-term bond yields adds to the global picture.

Thirty-year yields are particularly sensitive to long-term expectations surrounding inflation, fiscal policy, government borrowing and economic growth.

When long-duration yields rise simultaneously across major developed economies, the impact can spread through global asset-allocation decisions.

Investors may demand higher returns across a wider range of markets.

Higher yields can tighten global financial conditions

The consequences of rising bond yields extend well beyond fixed-income markets.

Higher benchmark yields can translate into:

More expensive corporate borrowing
Higher mortgage rates
Increased infrastructure financing costs
Lower valuations for long-duration equities
Higher government interest expenses
Greater pressure on leveraged businesses
More selective investment flows
Increased volatility in emerging markets

The overall effect is a tightening of financial conditions.

Growth stocks could face greater valuation pressure

High-growth companies are particularly sensitive to changes in interest rates.

Their valuations often depend on earnings and cash flows expected far into the future.

When the discount rate increases, those future cash flows become less valuable in present terms.

This can result in multiple compression even when the underlying company continues to grow.

Technology, internet, AI and other high-multiple segments could therefore remain particularly sensitive to movements in long-term Treasury yields.

AI stocks face a two-sided market dynamic

The AI investment cycle presents an unusual combination of opportunities and risks.

AI companies and infrastructure providers are benefiting from strong demand and substantial investment.

However, the infrastructure required to support the AI boom also requires enormous amounts of capital.

Companies building data centres and related infrastructure may rely increasingly on debt markets to fund expansion.

This could create a situation where the same AI boom supporting corporate earnings is also contributing to increased demand for debt financing.

Investors may consequently differentiate more carefully between companies generating strong cash flows and businesses requiring substantial external financing.

Government bond intervention may not solve structural issues

Market intervention can temporarily ease pressure in the Treasury market, but it may not eliminate the underlying forces driving long-term yields.

Fiscal deficits, debt issuance, economic growth, inflation expectations and investor demand are structural factors.

If these forces remain unfavourable, yields could continue to face upward pressure despite short-term policy measures.

This is why investors are increasingly focusing on the sustainability of government borrowing rather than simply monitoring central-bank policy rates.

India is not insulated from global bond-market stress

The rise in global yields is particularly relevant for India because global investors allocate capital across developed and emerging markets based on relative returns and risk.

When US Treasury yields rise significantly, Indian equities and bonds may need to offer a sufficient risk premium to remain attractive.

Higher US yields can therefore influence:

FII equity flows
Indian bond yields
Rupee valuation
Equity-market multiples
Corporate borrowing costs
Foreign investment decisions

This does not automatically imply a sustained fall in Indian markets, but it can increase volatility.

FII flows could become more important

Foreign institutional investor activity will remain an important market indicator.

If US Treasury yields rise sharply, global investors could become more selective about emerging-market exposure.

India's strong domestic liquidity and economic growth can provide support, but foreign flows can still influence short-term market direction.

A combination of rising US yields and FII selling could increase pressure on Indian benchmarks.

Rupee could face additional pressure

Higher US yields generally provide support to the dollar.

If the dollar strengthens while crude oil prices remain elevated, the Indian rupee could face additional pressure.

A weaker rupee can increase the local cost of imported commodities, particularly crude oil.

This creates a potential feedback mechanism involving the dollar, crude oil, inflation and Indian interest rates.

Crude oil adds another macroeconomic risk

Global bond-market concerns are emerging at the same time as crude oil prices have risen sharply because of renewed geopolitical tensions in West Asia.

Higher crude prices can increase India's import bill and potentially add to inflationary pressures.

For Indian equities, the combination of higher oil prices and higher US Treasury yields is particularly unfavourable because it can simultaneously affect corporate costs, currency markets, inflation expectations and foreign capital flows.

Nifty technical outlook turns cautious

The Indian equity-market technical setup has also weakened.

Ponmudi R, CEO of Enrich Money, identified 23,800 on the Nifty as an important support level.

According to him, the 24,000 and 24,200 zones are important levels that the benchmark needs to reclaim to improve its near-term outlook.

A sustained break below 23,800 could increase selling pressure, particularly if global markets remain under pressure from rising bond yields and crude oil.

Global markets face a valuation reset risk

If long-term bond yields remain elevated, equity markets could undergo a valuation reset.

This does not necessarily mean that corporate earnings will collapse.

Instead, investors could assign lower valuation multiples to the same earnings because the opportunity cost of investing in equities has increased.

The impact could therefore be more pronounced in expensive market segments.

Companies with strong cash flows may become more attractive

In a high-yield environment, investors may increasingly favour companies with:

Strong free cash flow
Low debt
Stable earnings
Pricing power
Sustainable dividends
High return on capital
Reasonable valuations

Companies that require continuous external financing may face greater pressure if borrowing costs remain high.

This could encourage greater differentiation within equity markets.

What investors should monitor

Investors should closely track the following indicators:

US 10-year Treasury yield

A sustained move above 5 per cent could materially increase global equity-market risk.

US 2-year Treasury yield

The two-year yield will provide clues about Federal Reserve expectations and short-term monetary policy.

US fiscal position

Government borrowing and Treasury issuance will influence the supply-demand balance in the bond market.

Nominal GDP growth

Strong nominal growth could keep pressure on long-term yields if it remains above prevailing bond yields.

Inflation expectations

Any renewed increase in inflation expectations could accelerate the rise in long-term yields.

AI-related debt issuance

The scale of corporate borrowing required for data centres and AI infrastructure could influence the broader credit market.

FII flows

Foreign buying or selling will remain important for Indian equity-market liquidity.

Crude oil

A sustained rise in oil prices could add pressure to India's inflation and currency outlook.

Nifty support levels

The 23,800 level remains an important technical marker, while 24,000-24,200 is the key recovery zone.

Three possible market scenarios

Scenario 1: Yields stabilise below 5%

If the US 10-year yield stabilises around current levels, markets may gradually absorb the higher interest-rate environment.

In this scenario, strong corporate earnings could continue to support equities, although valuation expansion may remain limited.

Scenario 2: Yield crosses 5% gradually

A gradual move above 5 per cent could result in a period of valuation adjustment.

High-multiple growth stocks may face pressure, while value-oriented and cash-generating companies could perform relatively better.

Scenario 3: Yield spikes above 5% rapidly

A sharp and disorderly move above 5 per cent would pose the greatest risk.

It could trigger simultaneous selling across bonds and equities, increase dollar demand and result in greater volatility in emerging markets.

This is the scenario that could produce the type of broad equity correction highlighted by Wood.

Market Outlook

The global market outlook has turned increasingly cautious, with bond yields emerging as one of the most important macro indicators for equity investors.

The US 10-year Treasury yield at 4.81 per cent is now close to the 5 per cent level identified by Christopher Wood as a potential trigger for a significant correction. At the same time, the Japanese 10-year yield has reached 3 per cent, while UK 30-year yields have climbed to their highest level since 1998.

The combination of US fiscal deterioration, strong nominal GDP growth, heavy Treasury issuance, AI-related corporate borrowing and rising global yields could keep upward pressure on long-term interest rates.

For India, the risk is amplified by elevated crude oil prices, rupee pressure and the possibility of changing FII flows. The Nifty's 23,800 support level and 24,000-24,200 recovery zone will remain important in the near term.

Investors should not interpret a rise in yields as an automatic signal to exit equities. Instead, the focus should be on whether yields rise gradually or move sharply higher, and whether corporate earnings are strong enough to offset the resulting valuation pressure.

A sustained move above 5 per cent in the US 10-year yield, particularly if accompanied by higher crude prices and weakening global liquidity, would represent a significant risk to equity markets. Conversely, stabilisation in bond yields, easing geopolitical tensions and moderation in crude prices could help markets absorb the current pressure.
