Barclays: Swaption Volumes Drop, Flows Slightly Long Volatility

The signal here is the mismatch between thinning liquidity and a tilt toward owning volatility, concentrated in long-dated tenors. That combination matters because it suggests positioning is being built for rate uncertainty rather than for carry, even as fewer participants are trading. Long-dated swaption demand is where hedging interest and relative-value bets overlap most, so it is the cleaner read on sentiment. Whether the long-vol skew persists if volumes stay subdued, or fades as the market thins further, is the open question.
