Yield Gap Regime Map

⬆ Wide & Widening

Maximum divergence — gap above 5Y average and still expanding. Strong USD carry advantage, EUR/USD downside pressure.

⬇ Wide & Narrowing

Gap above average but compressing — early convergence signal. Fed easing or Bund yield surge beginning to close the differential.

↗ Narrow & Widening

Gap below average but expanding — divergence building. Policy paths separating, dollar carry advantage increasing.

↘ Narrow & Narrowing CURRENT

Convergence regime — gap below average and compressing. Policy alignment, EUR/USD support, reduced transatlantic flow stress.

Current Regime Narrative

The US-Germany yield gap has narrowed from 2.20% (Dec 2025) to 1.55% as German Bund yields surged on massive fiscal spending plans (€500B+ infrastructure package announced Feb 2026). The gap is now below its 5-year average of 1.80%, reflecting ECB hawkishness and German fiscal expansion. This convergence supports EUR/USD strength and reduces the dollar carry advantage over the euro.

Historical frequency: 25% · Avg duration: 10 months

Yield Gap Drivers

NARROW German Fiscal Expansion (High)

Germany's €500B+ infrastructure spending plan is pushing Bund yields higher, narrowing the gap with US Treasuries. This is a structural shift from Germany's traditional fiscal conservatism.

NARROW ECB Rate Path (Medium)

ECB deposit rate at 2.50% with potential for further cuts. However, German fiscal expansion may limit ECB easing, keeping Bund yields elevated.

WIDEN Fed Rate Expectations (Medium)

Markets price 1-2 additional Fed cuts in 2026. Each cut narrows the gap by pulling US yields lower.

NARROW European Defense Spending (Medium)

Increased European defense spending (post-Ukraine) is adding to Bund supply and pushing yields higher.

Methodology

The US-Germany Yield Gap Index (UGYG) measures structural stress in the Treasury-Bund spread:

  • Gap Deviation (40%): |current_gap − avg_gap_5y| / 1.5 × 100, capped at 100.
  • Gap Velocity (35%): |gap_30d_change| / 0.5 × 100, capped at 100.
  • Extreme Signal (25%): |current_gap| / 3.0 × 100, capped at 100.

Signal thresholds: LOW <25, ELEVATED 25–49, HIGH 50–74, CRITICAL ≥75. v0.1-beta.

Frequently Asked Questions

What is the Treasury-Bund spread?▾
The Treasury-Bund spread is the difference between the US 10-year Treasury yield and the German 10-year Bund yield. As of Apr 8, 2026, the spread is 155 basis points (US 10Y at 4.31% minus Germany 10Y Bund at 2.76%). A wider spread reflects greater monetary policy divergence between the Fed and ECB, creating capital flow pressure toward USD assets and weighing on EUR/USD.
How does German fiscal expansion affect the Treasury-Bund spread?▾
Germany's €500B+ infrastructure spending package (announced Feb 2026) has pushed Bund yields sharply higher, narrowing the Treasury-Bund spread from 220bps (Dec 2025) to 155bps. Increased government bond issuance to fund fiscal expansion raises Bund yields, reducing the transatlantic yield differential. This is a structural shift from Germany's traditional fiscal conservatism and supports EUR/USD by reducing the dollar's carry advantage.
How does the ECB vs Fed policy divergence affect EUR/USD?▾
The Fed holds rates at 3.50–3.75% while the ECB is at 2.5%. This rate differential, reflected in the 155bps Treasury-Bund spread, is a primary driver of EUR/USD at 1.09. When the spread narrows (as it has recently due to German fiscal expansion pushing Bund yields higher), EUR/USD tends to strengthen. Conversely, a widening spread favors USD strength.
How does the US-Germany yield gap affect EUR/USD?▾
The 155bps yield gap creates incentives for capital to flow toward higher-yielding USD assets, putting downward pressure on EUR/USD. With EUR/USD at 1.09 and DXY at 97.5, the narrowing gap (from 220bps in Dec 2025) has supported euro strength. The 5-year average gap is 180bps — the current 155bps is below average, suggesting reduced USD carry advantage.
Will the Treasury-Bund spread narrow further in 2026?▾
Further narrowing depends on two forces: Fed rate cuts (markets price 1-2 additional cuts in 2026, pulling US yields lower) and German fiscal expansion (continued Bund issuance keeps German yields elevated). European defense spending adds further upward pressure on Bund yields. The base case is continued modest narrowing as German fiscal expansion is structural, but ECB rate cuts could partially offset by pulling shorter-dated European yields lower. The 5-year average gap is 180bps vs the current 155bps.
