Goldman Sachs Delta-One: Behind SoftBank's AGI-Fueled Surge, the Yen and Energy Are the Real Risks
nashnova research
SoftBank surged roughly 30% in three sessions on AI euphoria, but Goldman's Delta-One head Rich Privorotsky warns: the real systemic risks are yen carry-trade unwinds and energy price disruption — the AI rally buys the market a day or two at most.
SoftBank up 30% in three days — how long can AI euphoria last?
OpenAI's new model Astra triggered AGI expectations; combined with a tech conference and upbeat earnings from AMD and Cisco, SoftBank rallied roughly 30% over three sessions.
Privorotsky is blunt: this wave of AI optimism supports the market for a day or two at most.
This means → if a SoftBank spike looks like a bull-market signal, Goldman's read is the opposite — short-term sentiment is not a trend.
Why is a stronger yen making global equities nervous?
Japan's latest wage data beat expectations, reinforcing bets that the Bank of Japan will tighten policy. The yen is appreciating fast.
In plain terms = for years, traders borrowed cheap yen to buy global stocks and bonds — the "carry trade." A stronger yen forces those positions to unwind, sending shockwaves across asset classes worldwide.
Japanese exporters face a double squeeze — a stronger currency and rising energy costs — and are clearly lagging the broader market. Korea's KOSPI rose 2.5% intraday then reversed to close lower; even record corporate buybacks could not absorb the selling.
Energy — what is Goldman's "least willing to hold risk" scenario?
Privorotsky names energy as the biggest material risk to equities. Iran has proposed an exclusion zone that could restrict ship-to-ship crude transfers; Vitol's Hardy estimates Hormuz Strait throughput at roughly 10 million barrels per day.
Shanghai crude futures have been steadily outperforming, sparking speculation that China may have re-entered the market as a marginal buyer — after visibly compressing apparent demand earlier this summer.
Diplomatic signals offer some hope: Iran says talks with Oman are nearing a deal, but this is not yet an actionable framework, nor a broader U.S.–Iran agreement. This means → both sides have incentives to compromise, but without a landed deal, the risk of an energy price blow-up remains live.
Are European geopolitical risks escalating?
Russia closed the German consulate in St. Petersburg; German authorities are investigating infrastructure sabotage. Geopolitical friction is intensifying.
Russia's State Duma elections run September 18–20; Privorotsky flags the window around that date as a period to watch for escalation.
Copper hit a new high — is this a growth signal?
Copper quietly set a new London Metal Exchange record, but Privorotsky cautions: supply constraints and tariff distortions are the backdrop — this is not a pure growth signal.
He frames it as "late-cycle, spend-heavy" economics. In plain terms = equities and commodities can keep running until energy or rates rise enough to break demand — that is where the inflection sits.
Bonds and the Fed — what is the market waiting for?
Key events this week: 3-year Treasury auction, Treasury buyback-size announcement; Thursday's PPI and Friday's CPI are the main macro tests.
The market has priced in roughly three rate hikes, with about 61 basis points of implied tightening from September through next September.
Privorotsky argues that unless inflation data run genuinely hot, room for a major repricing is limited. This means → current hikes look more like "credibility maintenance" — the Fed signaling resolve, not actually trying to break the spending cycle.
