Capital Economics has warned that the spread between 10-year and 2-year US Treasury yields will narrow further in the coming months and that escalating tensions in the Strait of Hormuz could lead to a complete yield curve inversion. The firm forecasts the Federal Reserve will raise interest rates by 75 basis points over the next year — nearly double the 40 basis points currently priced by markets — making Capital Economics one of the most hawkish institutional forecasters in the current rate cycle. The yield curve flattening is already underway: the 10-year Treasury yield rose to 4.59% on Monday while the 2-year yield has been driven higher by rising rate hike expectations, compressing the spread between the two.Why the Curve Is Flattening — Short-Term Real Rates Rising FasterCapital Economics identifies the specific mechanism driving the flattening: short-term real rate expectations have risen more than long-term real rate expectations. "One reason for this divergence is that short-term real rate expectations have risen more than long-term real rate expectations, likely in response to strong economic data," the firm stated. This pattern is consistent with the current data environment — June nonfarm payrolls at 57,000 were soft, but the unemployment rate has continued to fall, consumer inflation expectations per the NY Fed reached 3.7% in July, and Brent crude at $82-85 is adding energy-driven inflation pressure that feeds directly into short-term CPI expectations.When short-term real rates rise faster than long-term rates, the yield curve flattens — the 2-year yield rises toward the 10-year yield, compressing the spread. A complete inversion — where the 2-year yields more than the 10-year — has historically been one of the most reliable leading indicators of recession in the US economy, having preceded every recession since the 1970s with a lead time of 6-18 months.The Hormuz Channel — How Oil Feeds Into Curve InversionCapital Economics explicitly links Strait of Hormuz escalation to the potential for complete yield curve inversion — a connection that runs through the inflation channel rather than the growth channel. Hormuz shipping at a three-week low of eight transits per day, Brent crude at $82-85 from a pre-conflict level of approximately $65, and the SPR at its lowest since 1983 reducing the government's ability to buffer supply shocks — all of these feed directly into the near-term inflation expectations that drive 2-year yields higher.The 10-year yield is more anchored by long-term growth and inflation expectations — expectations that incorporate the possibility of a recession slowing inflation over the medium term — while the 2-year yield reflects the market's pricing of Fed policy over the next two years. If Hormuz escalation keeps oil elevated and short-term inflation high, the Fed is forced to keep rates higher for longer, pushing the 2-year yield up. If that same oil shock simultaneously slows economic growth — the stagflation scenario — the 10-year yield stays contained as the market prices in eventual Fed cuts. The spread between the two compresses toward zero and potentially inverts.75 Basis Points vs 40 Basis Points — The Market Underpricing RiskCapital Economics' forecast of 75 basis points in Fed rate hikes over the next year against the market's current 40 basis points pricing represents a 35 basis point divergence that is significant for asset allocation. If Capital Economics is correct, the market is currently underpricing the Fed's tightening trajectory by nearly double — which means risk assets including Bitcoin are being priced with insufficient rate hike risk embedded in their valuations.The 75 basis point forecast is consistent with the current data picture Capital Economics is working from: September rate hike odds at 63% per CME FedWatch imply one 25 basis point hike with moderate probability. Capital Economics is projecting three 25 basis point hikes — September, November, and potentially January — in a scenario where Hormuz-driven energy inflation keeps headline CPI elevated through H2 2026 despite the labor market softening that the June payrolls miss had signaled.The Bitcoin Implications — Three Compounding HeadwindsA yield curve inversion driven by Hormuz-escalation-induced rate hikes would represent the most challenging single macro configuration for Bitcoin since the current correction began. Three headwinds compound simultaneously in that scenario. First, higher short-term rates increase the opportunity cost of holding non-yielding Bitcoin — the same mechanism that drove $4.06 billion in June ETF outflows when the 2-year yield was already elevated. Second, yield curve inversion historically signals recession risk — and recession fears produce broad risk-off de-risking that reduces institutional appetite for volatile assets like Bitcoin. Third, the Fed hiking 75 basis points against a backdrop of yield curve inversion and Hormuz-driven stagflation is the precise scenario in which the macro permission signal that Bitcoin's recovery thesis requires — a dovish FOMC — becomes most unlikely to arrive.The FOMC meeting on July 28-29 is now the most consequential scheduled event not just for Bitcoin's near-term price direction but for determining whether Capital Economics' 75 basis point forecast begins to be validated or is pushed back by a more data-dependent Fed communication.
