The reflex trade — global VIX up, emerging market currencies down — has weakened, and the reason is structural rather than cyclical. Research from the New York Fed's Liberty Street Economics team makes the case that the health of financial intermediaries in capital-source countries, not the risk appetite of destination markets, now sets the amplitude of currency pressure during global risk events. That is a substantive rewrite of the post-2013 taper-tantrum playbook, and it has direct implications for how policymakers and macro allocators should price the next shock.
The headline fact is that Exchange Market Pressure — an index that bundles FX moves with the interventions (rate hikes, reserve sales) central banks deploy to resist them — has become less responsive to global risk than at any point since the mid-2000s. Linda Goldberg and Samantha Hirschhorn document that EM sensitivity spiked immediately after the crisis, then fell below pre-crisis levels. For emerging markets, that composite matters more than the spot rate alone, because EM central banks lean against depreciation rather than let it run. Reading only the currency understates how much stress the system used to absorb.
The mechanism is a compositional shift in how cross-border credit reaches EM borrowers. Avdjiev, Gambacorta, Goldberg and Schiaffi show that the risk sensitivity of cross-border bank loans, which was significantly negative before 2008, became statistically insignificant afterward. International debt securities, by contrast, remain risk-sensitive — particularly for EM issuers. Post-crisis bank capital rules pushed riskier borrowers out of the loan book and into the bond market. Aggregate global liquidity looks calmer, but that calm partly reflects where the risk was warehoused, not whether it was extinguished.
The source-country balance sheet is the transmission variable
This is the operative claim: when a global risk shock hits, the depreciation pressure a given EM currency experiences depends less on that EM's own fundamentals than on the capital ratios of the banks and the leverage of the nonbank financial institutions (NBFIs) domiciled in the source country routing credit its way. Higher bank capitalization dampens the pass-through; higher NBFI leverage amplifies it. This makes source-country regulation an externality-generating policy — Basel-era capital rules have quietly become an EM FX stabiliser, while the migration of intermediation into thinly capitalised nonbanks is the offsetting risk.
Post-crisis bank capital rules are, in effect, an EM currency stabiliser — and the NBFI shadow is the offsetting risk.
Nina Boyarchenko and Leonardo Elias sharpen the tail. Their global credit factor — built from the excess bond premium (EBP, the component of corporate spreads not explained by default risk) and the VIX — is roughly flat when the VIX sits below its historical median of 18, then steepens sharply above it, with the slope amplifying at wider credit spreads. Boyarchenko and Elias take the YES side on the forecastable question of whether high readings of that factor predict elevated corporate bond returns, deteriorating local credit conditions, and outflows from global bond funds. The dossier offers no dissenting position — every named forecaster in the cluster sits on the same side of these questions at medium conviction, which readers should treat as a one-sided prior rather than a settled debate.
The operational read for the next risk-off episode: a VIX print that stays below 18 is likely to produce a muted EM currency response consistent with the post-crisis regime; a break above the median, combined with widening credit spreads, is where the nonlinearity bites and the source-country NBFI leverage channel becomes the variable to watch. The New York Fed's separate work on correlated NBFI drawdowns of bank credit lines flags the same pressure point from the other direction — that stress transmitted from nonbanks back into bank liquidity is a plausible two-year horizon risk, not a hypothetical one. The plumbing has been re-laid. It has not been made safe.
