YES Bank Shares Crash 14%: Which Mutual Funds Are Affected?

YES Bank shares crashed 14.4% on October 15, 2026, following a Supreme Court ruling involving ₹8,415 crore worth of bonds written off during its 2020 financial crisis. While shareholders faced a sharp decline, the development also raised an important question for mutual fund investors.

As of September 2026, mutual funds collectively owned 5.48% of YES Bank shares, meaning investors in several equity funds and ETFs have indirect exposure to the stock. Interestingly, some mutual funds were also among the investors affected by the original AT1 bond write off in 2020.

This creates an unusual situation. The same court ruling that has hurt YES Bank shareholders could potentially improve recovery prospects for certain historical bond investors. But the implications for someone investing in mutual funds today are very different.

Why Did YES Bank Shares Fall So Sharply?

The Supreme Court upheld an earlier Bombay High Court judgment that set aside YES Bank's decision to write off ₹8,415 crore of Additional Tier 1, or AT1, bonds during its 2020 reconstruction.

AT1 bonds are special instruments issued by banks to raise capital. Unlike ordinary fixed deposits, they carry substantial risk and can suffer losses when a bank faces serious financial trouble, subject to their terms and applicable regulations.

During the YES Bank crisis in March 2020, these bonds were written down to zero. Several bondholders subsequently challenged that decision, questioning whether the bank administrator had the legal authority to carry it out.

The Supreme Court ruling has now revived questions about the treatment of these bonds and their potential effect on the bank's finances. YES Bank shares fell from ₹21.20 in the previous session to approximately ₹18.15 on October 15.

For mutual fund investors, the concern is whether funds holding YES Bank shares will suffer losses as the market reassesses the bank's financial position.

How Much of YES Bank Is Owned by Mutual Funds?

YES Bank's September 2026 shareholding data shows that mutual funds owned approximately 171.93 crore shares, representing 5.48% of the bank's total equity.

This is lower than the 6.43% stake reported in June 2026. However, looking at a longer period reveals that mutual fund ownership has actually increased considerably from September 2025.

The ownership trend tells an interesting story. Mutual fund holdings increased steadily through June 2026 before declining in the latest reported quarter, although they remained above the level seen a year earlier.

However, this does not necessarily indicate a coordinated decision by active fund managers to reduce their conviction in YES Bank. The figures include index funds and arbitrage funds, whose transactions can be driven by index changes, investment flows and derivative strategies.

There is another important distinction. Mutual funds owning 5.48% of YES Bank does not mean every mutual fund has allocated 5.48% of its portfolio to the stock.

The first number shows how much of the bank mutual funds collectively own. What determines the impact on an individual investor is the percentage of a particular scheme invested in YES Bank.

Which Mutual Funds Hold YES Bank Shares?

September 2026 portfolio data shows YES Bank holdings across banking ETFs, actively managed equity schemes, hybrid funds and arbitrage funds.

Among the notable schemes are Nippon India ETF Nifty Bank BeES, DSP Nifty Bank ETF, ICICI Prudential Nifty Private Banks ETF and Baroda BNP Paribas Mid Cap Fund. These funds provide different types of exposure, despite owning shares of the same company.

The banking ETFs have exposure because YES Bank forms part of their underlying indices. For these funds, the portfolio is largely determined by index composition rather than a fund manager's individual opinion about YES Bank.

Baroda BNP Paribas Mid Cap Fund reported YES Bank exposure of approximately 1.38% in September 2026. Baroda BNP Paribas Value Fund had approximately 1.31%, while Baroda BNP Paribas Aggressive Hybrid Fund had approximately 1.06%.

These actively managed positions reflect portfolio decisions made within each scheme's investment mandate. Their exposure can change when fund managers rebalance their holdings.

Investors can compare mid cap mutual funds and individual scheme portfolios on INDmoney to understand how much of their investment is concentrated in particular companies.

An especially interesting part of the ownership data is the presence of large arbitrage fund positions. But these holdings need to be interpreted very differently.

Why Do Arbitrage Funds Hold So Many YES Bank Shares?

Among the notable holders in September were Invesco India Arbitrage Fund, with approximately ₹419 crore of YES Bank shares, and Kotak Arbitrage Fund, with approximately ₹418 crore.

At first glance, investors might assume that these funds are taking substantial bets on YES Bank's future share price. That conclusion would be misleading because arbitrage funds use a very different investment strategy.

An arbitrage fund typically purchases shares in the cash market and simultaneously creates an offsetting position in the futures market. Its objective is to benefit from the difference between these prices, rather than predict whether the stock will rise or fall.

For example, imagine a fund purchases YES Bank shares worth ₹100 and simultaneously establishes a corresponding futures position that benefits when the share price declines. A fall in the cash holding can be offset by a gain on the futures position.

The actual outcome depends on the size of the hedge, execution prices, transaction costs and market conditions. However, the important point is that a large reported equity holding does not necessarily represent an equally large directional investment.

That is why a sharp fall in YES Bank shares should not automatically be treated as an equivalent loss for funds such as UTI Arbitrage Fund, Invesco India Arbitrage Fund or Kotak Arbitrage Fund.

The distinction matters because the underlying investment strategy is more important than the name of a stock appearing in a holdings list. Investors can learn more about how arbitrage mutual funds manage stock-market exposure.

How Much Could the YES Bank Crash Affect Mutual Fund NAVs?

When a stock falls sharply, its impact on a mutual fund depends primarily on its portfolio weight. A stock representing 1% of a scheme's assets has much less influence on returns than one representing 10%, assuming other factors remain unchanged.

Consider the DSP Nifty Bank ETF, which had approximately 3.01% exposure to YES Bank in September 2026. If that allocation remained unchanged, a 14.4% decline in YES Bank shares would create a negative contribution of approximately 0.43 percentage points to the fund's return.

In simple terms, for every ₹10,000 invested in the ETF, the YES Bank position alone would contribute an estimated loss of around ₹43. This does not mean the ETF would actually decline by ₹43 because the prices of its other holdings also change.

Now consider Baroda BNP Paribas Mid Cap Fund, where YES Bank represented approximately 1.38% of the portfolio. The same 14.4% decline would create an estimated negative contribution of around 0.20 percentage points, equivalent to roughly ₹20 on a ₹10,000 investment.

These are illustrative calculations using September portfolio weights, not reported October 15 mutual fund returns. Actual results will depend on the holdings and hedges in place when the price movement occurred.

A mutual fund's Net Asset Value, or NAV, reflects the combined value of its investments after accounting for relevant liabilities and expenses. A sharp decline in one holding can therefore be offset by gains elsewhere in the portfolio.

This explains why a mutual fund can report a positive daily return even when one of its underlying stocks has crashed.

Investors unfamiliar with the calculation can read how mutual fund NAV works to understand how changes in stock prices affect the value of their investments.

Could the Fall Hurt Banking Mutual Funds More Than Other Categories?

Banking and financial services mutual funds are an obvious category to examine because they concentrate investments in financial companies. However, not every banking fund owns YES Bank, and even those that do may have very different allocations.

A diversified banking fund may primarily invest in HDFC Bank, ICICI Bank, State Bank of India, Axis Bank and several other financial institutions. Whether YES Bank's decline meaningfully affects its returns depends on the actual scheme portfolio.

The market movement on October 15 demonstrates why this matters. While YES Bank shares plunged, the broader Nifty Private Bank index gained approximately 1.9%, reflecting stronger performance from other banking stocks.

For a banking ETF holding YES Bank, losses from the stock could therefore be partly or fully offset by gains elsewhere in the index. The stock-specific decline does not automatically translate into an equally negative day for the entire banking category.

The same reasoning applies to diversified equity funds and hybrid funds. The larger and more varied the portfolio, the smaller the effect of an individual holding generally becomes, although diversification cannot eliminate market risk.

Investors comparing banking and financial services mutual funds should evaluate concentration, portfolio overlap and the financial health of underlying banks rather than reacting to a single stock headline.

Did Mutual Funds Also Lose Money in YES Bank AT1 Bonds in 2020?

The stock-market decline is only one part of the mutual fund story. The Supreme Court case relates to AT1 bonds, and several mutual fund schemes had exposure to these instruments during the YES Bank crisis in 2020.

This is particularly important because the impact on bond investors is fundamentally different from the impact on equity investors today.

When YES Bank entered reconstruction in March 2020, its AT1 bonds worth ₹8,415 crore were written off. Mutual funds, institutions and individual investors holding these instruments faced significant losses.

Nippon India Mutual Fund was among the affected fund houses. Its historical exposure included schemes such as Nippon India Credit Risk Fund, Nippon India Aggressive Hybrid Fund, Nippon India Equity Savings Fund, Nippon India Conservative Hybrid Fund and Nippon India Medium Duration Fund.

A Nippon India Mutual Fund disclosure covering December 31, 2025 listed approximately ₹2,483 crore of YES Bank AT1 exposure at face value across the specified schemes and segregated portfolios. That figure represents the original face value of the instruments, not their recoverable value or current NAV.

This is why the October 15 Supreme Court ruling has different implications for different groups of mutual fund investors.

Investors holding equity mutual funds with YES Bank shares face the effect of the share-price decline. Historical investors entitled to segregated portfolios containing the disputed AT1 bonds could potentially benefit if money is eventually recovered.

Neither outcome should be assumed to be automatic.

What Happens to Mutual Fund Investors if the AT1 Bonds Are Recovered?

When a bond held by a mutual fund experiences a severe credit event, such as a major credit-rating downgrade, the fund may create a segregated portfolio. This is commonly called a side pocket.

A side pocket separates the affected security from the remaining investments in the fund. The purpose is to prevent investors entering or exiting the normal fund from unfairly benefiting from, or being disadvantaged by, the distressed asset.

This mechanism was used by Nippon India Mutual Fund for affected YES Bank securities during the 2020 crisis.

Suppose an investor held units in an affected debt mutual fund when the segregated portfolio was created. That investor would have received corresponding units in the separate portfolio, while the remaining investments continued in the main fund.

Even if the investor later redeemed the main fund units, ownership of the segregated portfolio units could continue. A subsequent investment into the ordinary mutual fund would not automatically provide rights over those older segregated assets.

If an AMC recovers money from the distressed bonds, SEBI's segregated portfolio framework requires the recovered amount to be distributed to entitled unit holders in proportion to their holdings.

However, the Supreme Court ruling does not establish that investors will immediately receive the entire principal, unpaid coupons or any particular amount. Actual recovery will depend on the final implementation of the judgment, the bond terms, the amounts realised and the relevant AMC disclosures.

This is an important investor education lesson. Money recovered years after a credit event may still belong to investors who held the affected segregated portfolio, rather than being distributed across all current investors in the main mutual fund scheme.

Does the Supreme Court Ruling Make AT1 Bonds Safer for Debt Mutual Funds?

The verdict could have important implications for the rights of investors in the specific YES Bank instruments. But it does not eliminate the underlying risks of AT1 bonds.

These bonds are designed to absorb losses when banks face serious financial difficulties. Depending on the terms, investors may lose part or all of their principal, coupon payments may be cancelled, and the instrument may not be repaid on an expected call date.

The YES Bank dispute concerned the legal authority and process used for the particular 2020 write off. It should not be interpreted as a ruling that AT1 bonds issued by every bank are protected against future losses.

For debt mutual fund investors, the broader lesson is that not all bonds carry the same level of risk. A portfolio containing government securities, highly rated corporate bonds and AT1 instruments can behave very differently under financial stress.

Debt fund investors should therefore examine the credit quality of their schemes and the type of securities they hold. A relatively high interest rate on a bond does not automatically make it a more attractive investment.

The debt mutual fund category includes strategies with different levels of credit and interest-rate risk, making scheme selection and portfolio analysis important.

Should Mutual Fund Investors Change Their Investments After the YES Bank Crash?

For existing investors, the most useful response is to understand their actual exposure before making a decision. The presence of YES Bank in a mutual fund does not by itself determine whether the scheme remains suitable.

An investor can assess the situation by checking the following factors.

• Actual YES Bank allocation. Check whether the scheme holds YES Bank and what percentage of the portfolio it represents.
• Type of exposure. Distinguish conventional equity funds, index ETFs and hedged arbitrage positions.
• Portfolio concentration. Examine whether several funds in the portfolio hold the same banking stocks, creating hidden overlap.
• Historical segregated portfolios. Investors affected by the 2020 bond crisis should check their statements and AMC disclosures for continuing rights in any segregated holdings.

It is also important to remember that SIPs invest periodically into an entire mutual fund portfolio, rather than into one stock alone. A single company-related event does not automatically invalidate a long-term SIP strategy.

However, repeated financial or governance problems in a major portfolio holding may be relevant when assessing a scheme's investment process and risk management.

Investors can use the INDmoney mutual fund screener and scheme portfolio disclosures to understand how their funds are invested.

What Should Mutual Fund Investors Watch Next?

The next major development is YES Bank's Q2 FY27 results, scheduled for October 17, 2026. These results will provide an opportunity for the bank to clarify the financial implications of the Supreme Court ruling.

CRISIL Ratings had previously estimated that a complete write back of the disputed AT1 instruments could reduce YES Bank's Common Equity Tier 1 capital ratio by approximately 2.3 to 2.5 percentage points. That was a conditional scenario, rather than a confirmed financial outcome following the judgment.

For equity mutual funds holding YES Bank, the important questions concern future profitability, capital strength and whether the ruling changes the underlying value of the bank.

For historical bond investors, the focus should be on any recovery process, revised security valuations and disclosures issued by the affected mutual fund houses.

For arbitrage funds, investors should continue to distinguish gross equity holdings from their net exposure after hedging. A large cash-market position alone is insufficient to assess the fund's risk.

Subsequent monthly portfolio disclosures will also show whether equity fund managers retain their YES Bank positions or change their allocations following the judgment. September data establishes exposure before the event, but it cannot reveal decisions made afterward.

Final Takeaway

The YES Bank share-price crash provides an important example of how one corporate event can have different consequences for different types of mutual funds.

Equity funds and banking ETFs holding the stock may experience a negative contribution to their NAVs. Arbitrage funds may have much of that price movement offset through futures positions, while historical debt fund investors holding segregated AT1 bond portfolios face a separate question about potential recovery.

The most important number for a current mutual fund investor is therefore not the 14.4% fall in YES Bank shares or the bank's 5.48% aggregate mutual fund ownership. It is the fund's own exposure, the investment strategy behind that exposure and the extent to which the portfolio is diversified.

The larger lesson is that understanding what a mutual fund owns is only the beginning. Investors also need to understand why it owns those assets and how the associated risks are managed.

That understanding is far more useful than reacting to a sharp movement in one stock.
