SoftBank CFO opens the door to breaching its own leverage ceiling

SoftBank has long marketed its 25% loan-to-value ratio as a kind of financial guardrail — a self-imposed ceiling designed to reassure investors that the firm’s massive, often volatile bets wouldn’t spiral into existential risk. Now the company’s own CFO is suggesting that guardrail might be more of a suggestion.

According to the Financial Times, SoftBank CFO Yoshimitsu Goto said the firm “does not rule out” the possibility of its LTV ratio temporarily climbing above that 25% threshold. In English: the company is telling the market to expect more borrowing, and not to panic when the numbers look stretched.

What the 25% line actually means

Loan-to-value ratio is a straightforward metric. It measures how much debt a company carries relative to the value of its assets. Think of it like a mortgage — if your house is worth $400K and you owe $100K, your LTV is 25%.

For SoftBank, that ratio has served as a credibility anchor. The firm manages roughly $200B in assets across its Vision Funds and direct holdings, with stakes in companies like Arm Holdings, T-Mobile, and a sprawling portfolio of private tech bets. Keeping leverage at or below 25% was Masayoshi Son’s way of saying: yes, we swing big, but we’re not reckless about it.

Breaching that ceiling — even temporarily — changes the calculus. It signals that SoftBank sees opportunities worth stretching its balance sheet for, or that existing asset valuations have softened enough to push the ratio higher without any new borrowing at all.

Why now

The timing matters. SoftBank has been on an aggressive spending tear, particularly in artificial intelligence. The firm committed $100B to its Stargate joint venture with OpenAI and Oracle, announced earlier this year. Son has called AI the defining investment opportunity of his career, which is saying something for a man who once handed $100B to a Saudi-backed fund and let it ride on WeWork.

That kind of capital deployment doesn’t come cheap. Even for a firm with SoftBank’s asset base, writing nine-figure and ten-figure checks requires either selling existing positions or taking on more debt. Goto’s comments suggest the company is leaning toward the latter, at least in the near term.

There’s also the Arm factor. SoftBank’s crown jewel — its roughly 90% stake in chip designer Arm Holdings — has seen its stock price fluctuate significantly over the past year. Arm shares traded above $180 at their peak but have pulled back meaningfully at various points. Since Arm represents a huge chunk of SoftBank’s asset column, any dip in its share price mechanically pushes the LTV ratio higher, even if debt levels stay flat.

What this means for investors

Here’s the thing about self-imposed limits: they only work as confidence signals if they’re actually maintained. The moment a company starts saying “temporarily” and “does not rule out,” the market has to recalibrate what that commitment is really worth.

That doesn’t mean SoftBank is heading for trouble. Plenty of well-run firms operate at LTV ratios well above 25%. But SoftBank isn’t a typical firm. Its portfolio is concentrated in tech and AI — sectors where valuations can swing 30% in a quarter. Higher leverage on a volatile asset base is a fundamentally different risk profile than higher leverage on, say, a portfolio of toll roads.

For crypto-adjacent observers, SoftBank’s AI spending spree has indirect implications. The firm’s massive bets on AI infrastructure could accelerate demand for decentralized compute networks and GPU tokenization projects — sectors that have been gaining traction as centralized AI costs balloon. If SoftBank is willing to lever up for AI, it validates the thesis that capital will flow aggressively into the space, with some of that inevitably spilling into crypto-native AI plays.

The risk to watch is a scenario where Arm’s valuation drops materially while SoftBank’s debt is elevated. That combination pushed the firm into crisis territory back in 2020, when it was forced into emergency asset sales. Son has said those days are behind him. Markets will be watching to see if that’s true.

Bottom line: SoftBank is telling the world it’s willing to borrow more aggressively to fund its AI ambitions. Whether that’s visionary or reckless depends entirely on whether Masayoshi Son’s bet on artificial intelligence pays off before the balance sheet gets uncomfortable. History suggests he’ll swing hard either way.
