Front-end pressure sustains flat curve; NIM compression and USD strength dominant.

Regime read
With the 10Y-2Y spread at 0.33, the curve indicates a late-cycle transition where the 3.63% Fed Funds Rate anchors the front end. High-frequency evidence suggests persistent flattening pressures NIM for banks while supporting the 118.07 DXY. Current tight HY spreads (2.65) remain vulnerable to any growth slowdown signaled by further inversion.
Transmission channels (asset · direction · mechanism)
UST 2Y
▲higher
Monetary policy shocks transmit primarily through the front-end via expectations of the path of the federal funds rate.
+0.70 ±0.10 bp per 100bp FFR shock3m
UST 10Y/2Y Spread
-flattens
Policy shocks move short rates more than long rates as term premiums remain anchored by long-run inflation expectations.
-0.15 ±0.04 bp spread change per 100bp FFR shock1m
S&P 500 Bank Index
▼lower
Curve flattening reduces Net Interest Margin (NIM) and disincentivizes maturity transformation by financial intermediaries.

USD Broad (DXY)
▲higher
Uncovered Interest Parity (UIP) deviations drive capital inflows toward the currency with higher short-term risk-free rates.
