What Happens to Your Retirement Plans If the Stock Market Drops 50%?

Read: I Review Investing Platforms for a Living, And SoFi Crypto Finally Changed My Mind

I’ve spent years reviewing investing platforms across stocks, options, ETFs, and now crypto. Most crypto platforms fall into one of two categories: fast-moving exchanges with regulatory uncertainty, or traditional financial firms that treat crypto like an afterthought. SoFi Crypto is one of the very few platforms that breaks that mold.

Investing in the stock market involves risk, and market downturns can happen unexpectedly, causing portfolio values to fall sharply.

That’s stressful enough when you’re still working and building retirement wealth. But when you’re already retired and relying on your savings as your sole source of income, a major market decline can have a much bigger impact.

A major market downturn doesn’t necessarily mean a 50% drop. Even a decline of 20% or 25% can do meaningful damage to a retirement portfolio, which is why it’s important to plan for that possibility in advance.

In this Reddit post, the OP wonders how a stock market crash might impact their retirement plans. It’s a very real and valid concern. But there are ways to protect yourself in that situation.

When building wealth for retirement, many investors keep a larger portion of their portfolio in stocks because stocks have historically offered stronger long-term growth potential. Once retired, many people choose a more balanced mix of stocks, bonds, and cash to reduce the impact of market volatility.

The reason? At that stage of life, you’re using your savings for income. That’s why having an extremely stock-heavy portfolio in retirement can be risky, especially if you may need to withdraw money during a downturn. If you’re forced to sell stocks at a loss to cover living expenses, that can hurt your portfolio’s long-term sustainability.

One common approach is to gradually reduce stock exposure as retirement approaches so that your portfolio includes a larger share of bonds and cash by the time you begin taking withdrawals.

Then, if stocks fall sharply, you may be able to draw from bond income or other lower-volatility assets instead of selling stocks at depressed prices. Bonds don’t always move in the same direction as stocks, which is why they can help reduce overall portfolio volatility. Bond prices can also decline, especially when interest rates rise, but they often behave differently from stocks and can still play an important stabilizing role in a portfolio.

Many retirees choose to keep one to two years’ worth of living expenses in cash or cash equivalents, so they have spending money available during market downturns. Some stock market downturns last longer than others. But if you have a nice amount of cash on hand, you’ll be positioned to withstand a longer recovery if need be. Some retirees choose to keep as much as three years of cash on hand, depending on their spending needs and comfort with risk.

It can be a scary thing to see your portfolio value take a dive during retirement. For that reason, a good bet is to consult with a qualified financial advisor before retirement and have them help you assemble a portfolio that’s better positioned to handle a stock market downturn.

A financial advisor can help make sure your portfolio is appropriately diversified and can also help you identify income-producing or lower-volatility assets that may support your spending needs in retirement. Plus, they can talk you through market events, because sometimes, even the most seasoned investors need a bit of reassurance.
