Yield Curve Control (YCC)
A monetary policy tool where a central bank commits to capping long-term interest rates at a specific level by purchasing whatever volume of bonds is necessary to maintain that cap. Japan's Bank of Japan has operated YCC since 2016, targeting 10-year JGB yields near 0%. YCC is effectively a commitment to unlimited bond purchases — a form of permanent QE when markets test the ceiling.
Why It Matters
BoJ YCC is the single largest distortion in global sovereign bond markets. When YCC breaks or the cap is widened (as in Dec 2022 and Jul 2023), Japanese institutional investors repatriate capital from US Treasuries and European bonds, causing global yield spikes.

Stealth QE
Liquidity injection mechanisms deployed by central banks that expand money supply without being officially labelled as Quantitative Easing. Historical examples include the Fed's Bank Term Funding Program (BTFP, March 2023 — ~$180B), unscheduled overnight repo operations in September 2019, and the ECB's Pandemic Emergency Purchase Programme (PEPP) extensions. The purpose is operational: inject liquidity while maintaining a hawkish public narrative.SOFR (Secured Overnight Financing Rate)
The benchmark US dollar overnight interest rate, computed by the New York Fed as the volume-weighted median rate on overnight Treasury-collateralised repo transactions. SOFR replaced LIBOR as the global reference rate for dollar-denominated interest rate derivatives in 2023. It reflects the true cost of overnight dollar funding in the US financial system.Breakeven Inflation Rate
The market-implied expected inflation rate over a given period, derived from the yield differential between nominal Treasury bonds and Treasury Inflation-Protected Securities (TIPS) of the same maturity. If the 10-year nominal yield is 4.5% and the 10-year TIPS yield is 2.0%, the 10-year breakeven inflation rate is 2.5% — meaning markets expect average inflation of 2.5% per year for a decade.Ready to see this live?
