Emerging markets have developed stronger immune systems. US debt dynamics are deteriorating and the Federal Reserve has started hiking interest rates, yet EM appears under no pressure to follow suit.

The US has sneezed, but EM isn't catching the proverbial cold. Historically, when the Fed starts tightening policy, emerging economies are forced to hike as well, even if their domestic economies aren't strong enough to warrant it, due to currency concerns and debt dynamics.

This has given rise to another market cliche: the Fed is central banker to the world. But surprisingly resilient economic growth across emerging economies this year, sturdier fiscal fundamentals, and relatively high interest rates and bond yields are offering EM central banks a degree of flexibility.

That could allow them to start cutting rates in the next year, or, at the very least, enable them not to follow the Fed in lockstep as it tightens. RATE BUFFEREmerging markets - like their developed peers - are currently beset by a host of risks stemming from geopolitical strife, trade frictions, the energy price shock, and AI bubble fears.

But even though some EM countries are particularly vulnerable, either to persistently high energy prices or a sudden, disorderly unwind of the AI trade, the threat of rapidly tightening monetary policy is mostly absent. This is largely because policy rates are already elevated across much of EM.

45%, according to State Street. Lofty policy rates have helped restore EM central bank credibility, support exchange rates, and create a real rate buffer.

Bank of America strategists say EM rates at the front end of the curve have "materially" overshot to such an extent that implied policy rates next year will be in restrictive territory in all major emerging economies except China." Widespread tightening seems unlikely," State Street strategists wrote earlier this month.

While EMs look surprisingly calm, robust, and attractive - with some notable exceptions like Indonesia - the same cannot be said of their developed-market peers. While many emerging countries appear to be strengthening their economic fundamentals, investors' concern over the fiscal trajectory in the US, Japan, much of the euro zone, and the UK has sent yields across the industrialized world to the highest in decades.

PIQUE INTERESTInvestors are positioning accordingly. A JPMorgan survey of investors at the International Monetary Fund/World Bank meetings in Bangkok last week showed that 33% favor EM stocks, compared with 26% who prefer developed market equities.
