ECB Rate Hike Forecast: A 25bps Flow Shock

The core driver is a persistent energy-driven inflation shock from Middle East disruptions. Goldman Sachs now expects shipping through the Strait of Hormuz "to remain at only 5% of normal levels for 6 weeks," leading it to forecast Brent crude at $80 per barrel by year-end. This surge directly pressures euro zone inflation, with Goldman revising its headline forecast to peak at 3.2% in the second quarter.

This shock triggered a sharp hawkish pivot in market expectations. Goldman's revised outlook calls for two 25 basis point ECB hikes in April and June, a dramatic shift from its previous forecast of steady rates through 2026. The ECB itself held its key rate at 2% but signaled a low hurdle for hikes, with policymakers now expected to discuss tightening in the coming months.

The parallel shift is clear in the UK. The Bank of England held rates at 3.75% and flagged elevated inflation risks, prompting Goldman to delay its forecast for rate cuts until 2027. This marks a close call for the BoE, with a significant risk of a near-term hike if energy prices climb further.

The Flow Impact: Liquidity and Asset Prices

Higher interest rates tighten financial conditions, directly reducing liquidity for risk assets. The ECB's shift toward a 25 basis point hike in April and June will drain reserves from the banking system and raise funding costs, a classic flow shock that typically leads to lower asset valuations and reduced trading activity.

This policy pivot is occurring alongside a significant growth downgrade. Goldman Sachs has cut its euro area growth forecast to 0.7% for year-end, a further 0.3 percentage point reduction. The inflation shock is dampening consumer spending, creating a headwind for corporate earnings and equity flows.

While the baseline for unchanged ECB rates remains, the risk is now tilted toward hikes. This uncertainty itself can increase market volatility and trading volume as investors reassess positioning. The setup favors a period of choppiness until the direction of the first hike is confirmed.

Catalysts and Risks: The Energy Price Flow

The primary catalyst confirming or breaking the new forecast is the duration of the energy price shock. Goldman's model assumes shipping through the Strait of Hormuz will remain disrupted at only 5% of normal levels for 6 weeks. This assumption underpins its forecast for high energy prices and a peak in euro area headline inflation at 3.2%. A faster resolution to Middle East tensions would ease inflation pressures and allow the ECB to maintain its pause. Conversely, a prolonged conflict would reinforce the hike path.

The key watchpoint for the broader disinflation trajectory is the core PCE inflation gauge in the US. Goldman Sachs now targets a 3.05% year-over-year jump in core PCE, indicating the "last mile" of disinflation is longer than expected. This matters because the Federal Reserve's policy pivot hinges on this gauge, and a stubbornly high core PCE would pressure global financial conditions, potentially forcing the ECB to act more aggressively to anchor inflation expectations.

The setup creates a dual risk. On one hand, the energy shock is already dampening growth, with Goldman downgrading euro area forecasts to 0.7% for year-end. On the other, the magnitude of the energy shock is introducing more persistence into core inflation. The ECB's response will be a direct function of which force wins: the flow of higher energy prices or the flow of weaker economic activity.
