Oaktree's Howard Marks on Unpredictability, Importance and Investing in AI

Howard Marks, after nearly five decades lending to below-investment-grade companies, now faces what he calls the most unpredictable environment of his lifetime. The very power that makes artificial intelligence important also makes it impossible to forecast — raising existential questions about employment, corporate survival, and the validity of 30-year bonds issued by tech giants. Meanwhile, a once-hot asset class — private credit — has shifted from «what about private credit?» (enthusiastic) to «what about private credit?» (anxious), as early advantages erode and retail investors discover illiquidity the hard way. Can traditional investment judgment survive when AI can read everything, remember everything, and extrapolate patterns faster than any human — yet lacks the intuition to sense when «the hairs on the back of your neck stand up»?

Punti chiave

1

AI is rendering the investment world far less predictable than at any prior point, because the same transformative power that gives it importance also makes its consequences unknowable.

2

Private credit has moved from lush early-mover advantage (high rates, strong safety) to equilibrium with public credit, as competition bid down spreads to roughly 125 basis points — adequate but no longer special.

3

Lending to AI or tech companies for fixed returns is likely a mistake; if you're taking fundamental business-model risk in an unpredictable environment, you should own equity and capture upside, not accept bond coupons.

4

The worst loans are made in the best of times: 17 years of low defaults and easy money have bred complacency, FOMO, and lax underwriting — setting the stage for an eventual default cycle.

5

AI is a powerful research and pattern-recognition tool, but it makes predictions (hypotheses) rather than judgments; humans still need to assess character, exercise intuition, and decide when assets are cheap enough to buy aggressively.

In breve

Marks believes AI's sweeping, unpredictable impact renders most forward-looking predictions unreliable, yet he remains confident that assets can still become cheap enough to warrant aggressive buying — so long as human intuition, not algorithmic prediction, guides the final call.

Private Credit: From FOMO to Fear

Private credit has shifted from lush advantage to equilibrium pricing.

THEN (2011–2023)
Early-Mover Advantage
When banks pulled back after the global financial crisis, non-bank lenders stepped into mid-sized buyout lending with limited supply and strong demand. They commanded high interest rates and robust safety provisions, delivering strong risk-adjusted returns as the «specialness» of the asset class was undeniable.
NOW (2024–present)
Equilibrium and Anxiety
Success attracted capital; competition bid down yields and safety. Private credit now offers roughly 125 basis points over public credit (8.25% vs. 7%) — fair compensation for illiquidity, but no longer lush. Retail investors, sold on promise without full understanding of illiquidity, are now «shocked» to discover long-standing limitations as defaults loom.

The Most Unpredictable Environment Ever

AI's transformative power makes the future impossible to forecast with confidence.

Marks argues that artificial intelligence has introduced a degree of uncertainty unprecedented in his 48-year career. The very capabilities that make AI important — its ability to displace labor, render software obsolete, and reshape entire industries — also make it impossible to model with any reliability. «We've never contemplated questions like these,» he notes, pointing to the potential for mass unemployment, societal upheaval, and the collapse of business models that seemed durable just months ago.

This unpredictability has profound investment implications. Marks has always maintained that successful investing requires two things: a view of what will happen and an honest assessment of the probability that view is correct. In the age of AI, he believes the second element — confidence in one's forecast — has collapsed. The result is a world where lending money to companies for 30 or 40 years (as Google, Microsoft, and Amazon have done) looks less like prudent stewardship and more like «optimism and credulousness in the ascendancy.»

For Marks, this is not a reason to abandon investing, but it is a reason to demand a higher margin of safety, to favor equity over debt when taking business-model risk, and to wait for assets to become genuinely cheap before deploying capital aggressively.

Lending to AI Companies: A Mistake

If you're taking fundamental business risk, own equity — don't lend.

⚠️

Lending to AI Companies: A Mistake

Marks quotes Oaktree colleague Bob O'Leary: if you're going to finance AI or tech companies in this environment, «you should probably buy the stock and get the upside if it ensues, rather than just lend the money and get a fixed return if they're successful.» Lending for fixed coupons while shouldering existential business-model risk is a mismatch — you bear downside without participating in upside.

What AI Can and Cannot Do for Investors

📚
Universal Knowledge
AI has read everything ever written, remembers it all, and can retrieve it instantly without error — a dramatic advantage over human memory.
🔢
Flawless Execution
It extrapolates patterns, makes calculations without arithmetic mistakes, and avoids emotional biases like euphoria at tops or panic at bottoms.
🤖
Prediction, Not Judgment
AI generates hypotheses based on historical patterns, but it predicts rather than judges. It cannot sense when «the hairs on the back of your neck stand up» or assess character.
🧠
Human Intuition Still Essential
Marks believes Oaktree has saved clients money by avoiding «bad people» — a skill AI lacks. The firm uses AI as a research aid but will not turn the investment process over to it.

The Worst Loans Are Made in the Best of Times

Seventeen years of low defaults bred complacency and set up the next cycle.

Marks observes that the financial markets have enjoyed an extraordinary run since March 2009 — 17 years with only brief interruptions (three bad weeks in March 2020, a poor 2022). During such periods, money flows freely, lenders compete for deals by lowering standards, and FOMO replaces skepticism. «The worst loans are made in the best of times,» Marks repeats, because easy money creates the conditions for undeserving credits to get funded and frauds to be perpetuated.

He points to the bankruptcies of First Brands and Tricolor in late 2024 as early warning signs — «cockroaches in the coal mine.» These failures, some involving probable fraud, are the natural result of a long period of lax underwriting. Marks expects more shoes to drop: «It's only when the tide goes out that we find out who's swimming naked,» borrowing Buffett's phrase. Yield spreads on sub-investment-grade credit remain at the low end of historical ranges, suggesting the market has not yet priced in elevated defaults.

Key Figures from the Conversation

Notable data points illustrating market conditions and AI's impact.

Oaktree High Yield Bond Success Rate (since 1978)
99%
Marks reports that 99% of high yield bonds Oaktree has purchased over 48 years have paid off, underscoring the fundamental soundness of lending to below-investment-grade companies when done with discipline.
Private Credit Yield Premium Over Public (circa late 2024)
~125 basis points
Direct lending was yielding approximately 8.25% versus 7% for public credit — adequate compensation for illiquidity, but no longer lush or special.
S&P 500 Gain Since September 2022
~100% (doubled)
Marks notes that since roughly September 30, 2022, the S&P 500 has doubled in price, despite intrinsic values not doubling — evidence of exuberance.
Google 100-Year Bond Yield
5.8%
Marks cites Google's issuance of century bonds at 5.8% as emblematic of «optimism and credulousness» in an unpredictable environment.
Block Workforce Reduction (one day, early 2025)
4,000 employees (40%)
A company with 10,000 employees cut 40% in a single day because AI could do the work cheaper and faster — illustrating AI's disruptive potential.

Waiting for the Buying Point

Marks remains cautious until assets become cheap enough to warrant aggression.

I'm always cautious until the time when I believe... that caution has to be overcome. And by the way, a lender should be 80% caution. So I think we'll remain cautious until we believe that the disappointment and the declines have been profound enough to make it time to be aggressive. And then hopefully, as we have in past cycles, hopefully we'll be the best, most aggressive people on the planet. And, by the way, may be the only aggressive people left on the planet.

Glossario
FOMO (Fear of Missing Out)The emotional drive to invest based on anxiety that others are profiting, which displaces disciplined analysis and elevates risk.
Yield SpreadThe difference in yield between a riskier bond (e.g., high yield) and a safer benchmark (e.g., Treasuries or investment-grade credit); narrow spreads indicate low perceived risk.
BDC (Business Development Company)A publicly traded vehicle that invests in private companies and distributes most income to shareholders; often used to give retail investors access to private credit.
Mark-to-MarketValuing an asset based on its current market price; private credit often lacks this transparency because holdings are illiquid and not exchange-traded.
Direct LendingNon-bank lenders providing loans directly to companies (often for buyouts), bypassing traditional bank intermediaries.
