QCP Macro Themes - 12 August 2026

The Fed held rates at 3.50%–3.75% for a fifth consecutive meeting, but the 9–3 vote revealed its deepest split since September 2016. Three dissenters argued that persistent inflation and a resilient labour market warranted earlier action, while reduced forward guidance has made each meeting harder to price.

Markets still assign a 57% chance of a September rate cut, even as the 30-year Treasury yield has climbed to 5.21%—a 19-year high. The disconnect between policy expectations and long-end yields is keeping the rates outlook unsettled.

That uncertainty extends to FX. After the yen weakened beyond ¥163 per dollar, Japan’s estimated ¥8.45tn intervention pushed USD/JPY back towards ¥157. The US joined a day later with an estimated $5–10bn operation—the first joint US–Japan yen-buying intervention since 1998—reinforcing that policymakers are prepared to act again.

When central banks stop guiding and start intervening, which policy signal should markets trust?
